+Panic Timeouts
+--------------
+
+The OpenIPMI driver supports the ability to put semi-custom and custom
+events in the system event log if a panic occurs. if you enable the
+'Generate a panic event to all BMCs on a panic' option, you will get
+one event on a panic in a standard IPMI event format. If you enable
+the 'Generate OEM events containing the panic string' option, you will
+also get a bunch of OEM events holding the panic string.
+
+
+The field settings of the events are:
+* Generator ID: 0x21 (kernel)
+* EvM Rev: 0x03 (this event is formatting in IPMI 1.0 format)
+* Sensor Type: 0x20 (OS critical stop sensor)
+* Sensor #: The first byte of the panic string (0 if no panic string)
+* Event Dir | Event Type: 0x6f (Assertion, sensor-specific event info)
+* Event Data 1: 0xa1 (Runtime stop in OEM bytes 2 and 3)
+* Event data 2: second byte of panic string
+* Event data 3: third byte of panic string
+See the IPMI spec for the details of the event layout. This event is
+always sent to the local management controller. It will handle routing
+the message to the right place
+
+Other OEM events have the following format:
+Record ID (bytes 0-1): Set by the SEL.
+Record type (byte 2): 0xf0 (OEM non-timestamped)
+byte 3: The slave address of the card saving the panic
+byte 4: A sequence number (starting at zero)
+The rest of the bytes (11 bytes) are the panic string. If the panic string
+is longer than 11 bytes, multiple messages will be sent with increasing
+sequence numbers.
+
+Because you cannot send OEM events using the standard interface, this
+function will attempt to find an SEL and add the events there. It
+will first query the capabilities of the local management controller.
+If it has an SEL, then they will be stored in the SEL of the local
+management controller. If not, and the local management controller is
+an event generator, the event receiver from the local management
+controller will be queried and the events sent to the SEL on that
+device. Otherwise, the events go nowhere since there is nowhere to
+send them.
+
+
+Poweroff
+--------
+
+If the poweroff capability is selected, the IPMI driver will install
+a shutdown function into the standard poweroff function pointer. This
+is in the ipmi_poweroff module. When the system requests a powerdown,
+it will send the proper IPMI commands to do this. This is supported on
+several platforms.
+
+There is a module parameter named "poweroff_control" that may either be zero
+(do a power down) or 2 (do a power cycle, power the system off, then power
+it on in a few seconds). Setting ipmi_poweroff.poweroff_control=x will do
+the same thing on the kernel command line. The parameter is also available
+via the proc filesystem in /proc/ipmi/poweroff_control. Note that if the
+system does not support power cycling, it will always to the power off.
+
+Note that if you have ACPI enabled, the system will prefer using ACPI to
+power off.

+Block io priorities
+===================
+
+
+Intro
+-----
+
+With the introduction of cfq v3 (aka cfq-ts or time sliced cfq), basic io
+priorities is supported for reads on files. This enables users to io nice
+processes or process groups, similar to what has been possible to cpu
+scheduling for ages. This document mainly details the current possibilites
+with cfq, other io schedulers do not support io priorities so far.
+
+Scheduling classes
+------------------
+
+CFQ implements three generic scheduling classes that determine how io is
+served for a process.
+
+IOPRIO_CLASS_RT: This is the realtime io class. This scheduling class is given
+higher priority than any other in the system, processes from this class are
+given first access to the disk every time. Thus it needs to be used with some
+care, one io RT process can starve the entire system. Within the RT class,
+there are 8 levels of class data that determine exactly how much time this
+process needs the disk for on each service. In the future this might change
+to be more directly mappable to performance, by passing in a wanted data
+rate instead.
+
+IOPRIO_CLASS_BE: This is the best-effort scheduling class, which is the default
+for any process that hasn't set a specific io priority. The class data
+determines how much io bandwidth the process will get, it's directly mappable
+to the cpu nice levels just more coarsely implemented. 0 is the highest
+BE prio level, 7 is the lowest. The mapping between cpu nice level and io
+nice level is determined as: io_nice = (cpu_nice + 20) / 5.
+
+IOPRIO_CLASS_IDLE: This is the idle scheduling class, processes running at this
+level only get io time when no one else needs the disk. The idle class has no
+class data, since it doesn't really apply here.
+
+Tools
+-----
+
+See below for a sample ionice tool. Usage:
+
+# ionice -c<class> -n<level> -p<pid>
+
+If pid isn't given, the current process is assumed. IO priority settings
+are inherited on fork, so you can use ionice to start the process at a given
+level:
+
+# ionice -c2 -n0 /bin/ls
+
+will run ls at the best-effort scheduling class at the highest priority.
+For a running process, you can give the pid instead:
+
+# ionice -c1 -n2 -p100
+
+will change pid 100 to run at the realtime scheduling class, at priority 2.

-Linux 2.4.x support is not planned, but patches are very welcome.
-
-NOTE: I'm using Debian testing, so the following explaination (especially

-1.2. Compiling
-
-Since the driver is in the linux kernel, activating the driver in
-your favorite config-environment should sufficient. I recommend
-to compile the driver as module. Hotplug does the rest.
-
-1.3. Loading the drivers
-
-Hotplug is able to load the driver, when it is needed (because you plugged
-in the device).
-
-If you want to enable debug output, you have to load the driver manually and
-from withing the dvb-kernel cvs repository.
-
-first have a look, which debug level are available:
-
-modinfo dib3000mb
-modinfo dib3000-common
-modinfo dib3000mc
-modinfo dvb-dibusb
-
-modprobe dib3000-common debug=<level>
-modprobe dib3000mb debug=<level>
-modprobe dib3000mc debug=<level>
-modprobe dvb-dibusb debug=<level>
-
-should do the trick.
-
-When the driver is loaded successfully, the firmware file was in
-the right place and the device is connected, the "Power"-LED should be
-turned on.
-
-At this point you should be able to start a dvb-capable application. For myself
-I used mplayer, dvbscan, tzap and kaxtv, they are working. Using the device
-in vdr is working now also.
-
-2. Known problems and bugs
-
-- Don't remove the USB device while running an DVB application, your system will die.
-
-2.1. Adding support for devices
-
-It is not possible to determine the range of devices based on the DiBcom
-reference designs. This is because the reference design of DiBcom can be sold
-to thirds, without telling DiBcom (so done with the Twinhan VP7041 and
-the HAMA device).
-
-When you think you have a device like this and the driver does not recognizes it,
-please send the ****load*.inf and the ****cap*.inf of the Windows driver to me.
-
-Sometimes the Vendor or Product ID is identical to the ones of Twinhan, even
-though it is not a Twinhan device (e.g. HAMA), then please send me the name
-of the device. I will add it to this list in order to make this clear to
-others.
-
-If you are familar with C you can also add the VID and PID of the device to
-the dvb-dibusb-core.c-file and create a patch and send it over to me or to
-the linux-dvb mailing list, _after_ you have tried compiling and modprobing
-it.
-
-2.2. USB1.1 Bandwidth limitation
-
-Most of the currently supported devices are USB1.1 and thus they have a
-maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.
-This is not enough for receiving the complete transport stream of a
-DVB-T channel (which can be about 16 MBit/s). Normally this is not a
-problem, if you only want to watch TV (this does not apply for HDTV),
-but watching a channel while recording another channel on the same
-frequency simply does not work very well. This applies to all USB1.1
-DVB-T devices, not just dibusb)
-
-Update: For the USB1.1 and VDR some work has been done (patches and comments
-are still very welcome). Maybe the problem is solved in the meantime because I
-now use the dmx_sw_filter function instead of dmx_sw_filter_packet. I hope the
-linux-dvb software filter is able to get the best of the garbled TS.
-
-The bug, where the TS is distorted by a heavy usage of the device is gone
-definitely. All dibusb-devices I was using (Twinhan, Kworld, DiBcom) are
-working like charm now with VDR. Sometimes I even was able to record a channel
-and watch another one.
-
-2.3. Comments
-
-Patches, comments and suggestions are very very welcome.

+Documentation for dvb-usb-framework module and its devices
+
+Idea behind the dvb-usb-framework
+=================================
+
+In March 2005 I got the new Twinhan USB2.0 DVB-T device. They provided specs and a firmware.
+
+Quite keen I wanted to put the driver (with some quirks of course) into dibusb.
+After reading some specs and doing some USB snooping, it realized, that the
+dibusb-driver would be a complete mess afterwards. So I decided to do it in a
+different way: With the help of a dvb-usb-framework.
+
+The framework provides generic functions (mostly kernel API calls), such as:
+
+- Transport Stream URB handling in conjunction with dvb-demux-feed-control
+ (bulk and isoc are supported)
+- registering the device for the DVB-API
+- registering an I2C-adapter if applicable
+- remote-control/input-device handling
+- firmware requesting and loading (currently just for the Cypress USB
+ controllers)
+- other functions/methods which can be shared by several drivers (such as
+ functions for bulk-control-commands)
+- TODO: a I2C-chunker. It creates device-specific chunks of register-accesses
+ depending on length of a register and the number of values that can be
+ multi-written and multi-read.
+
+The source code of the particular DVB USB devices does just the communication
+with the device via the bus. The connection between the DVB-API-functionality
+is done via callbacks, assigned in a static device-description (struct
+dvb_usb_device) each device-driver has to have.
+
+For an example have a look in drivers/media/dvb/dvb-usb/vp7045*.
+
+Objective is to migrate all the usb-devices (dibusb, cinergyT2, maybe the
+ttusb; flexcop-usb already benefits from the generic flexcop-device) to use
+the dvb-usb-lib.
+
+TODO: dynamic enabling and disabling of the pid-filter in regard to number of
+feeds requested.
+

+
+1. How to use?
+1.1. Firmware
+
+Most of the USB drivers need to download a firmware to the device before start
+working.
+
+Have a look at the Wikipage for the DVB-USB-drivers to find out, which firmware
+you need for your device:
+
+http://www.linuxtv.org/wiki/index.php/DVB_USB
+
+1.2. Compiling
+
+Since the driver is in the linux kernel, activating the driver in
+your favorite config-environment should sufficient. I recommend
+to compile the driver as module. Hotplug does the rest.
+
+If you use dvb-kernel enter the build-2.6 directory run 'make' and 'insmod.sh
+load' afterwards.
+
+1.3. Loading the drivers
+
+Hotplug is able to load the driver, when it is needed (because you plugged
+in the device).
+
+If you want to enable debug output, you have to load the driver manually and
+from withing the dvb-kernel cvs repository.
+
+first have a look, which debug level are available:
+
+modinfo dvb-usb
+modinfo dvb-usb-vp7045
+etc.
+
+modprobe dvb-usb debug=<level>
+modprobe dvb-usb-vp7045 debug=<level>
+etc.
+
+should do the trick.
+
+When the driver is loaded successfully, the firmware file was in
+the right place and the device is connected, the "Power"-LED should be
+turned on.
+
+At this point you should be able to start a dvb-capable application. I'm use
+(t|s)zap, mplayer and dvbscan to test the basics. VDR-xine provides the
+long-term test scenario.
+
+2. Known problems and bugs
+
+- Don't remove the USB device while running an DVB application, your system
+ will go crazy or die most likely.

+For further details about TwinHan DST + clones see /Documentation/dvb/ci.txt.
-3a) Nebula / Pinnacle PCTV
+3a) The manual approach
+-----------------------
+
+Loading modules:
+modprobe bttv
+modprobe dvb-bt8xx
+
+Unloading modules:
+modprobe -r dvb-bt8xx
+modprobe -r bttv
+
+3b) The automatic approach
--------------------------
- $ modprobe bttv (normally bttv is being loaded automatically by kmod)
- $ modprobe dvb-bt8xx (or just place dvb-bt8xx in /etc/modules for automatic loading)
+If not already done by installation, place a line either in
+/etc/modules.conf or in /etc/modprobe.conf containing this text:
+alias char-major-81 bttv
+Then place a line in /etc/modules containing this text:
+dvb-bt8xx
-3b) TwinHan and Clones
---------------------------
-
- $ modprobe bttv i2c_hw=1 card=0x71
- $ modprobe dvb-bt8xx
- $ modprobe dst
-
-The value 0x71 will override the PCI type detection for dvb-bt8xx,
-which is necessary for TwinHan cards.
-
-If you're having an older card (blue color circuit) and card=0x71 locks
-your machine, try using 0x68, too. If that does not work, ask on the
-mailing list.
-
-The DST module takes a couple of useful parameters.
-
-verbose takes values 0 to 5. These values control the verbosity level.
-
-debug takes values 0 and 1. You can either disable or enable debugging.
-
-dst_addons takes values 0 and 0x20. A value of 0 means it is a FTA card.
-0x20 means it has a Conditional Access slot.
-
-The autodected values are determined bythe cards 'response
-string' which you can see in your logs e.g.
-
-dst_get_device_id: Recognise [DSTMCI]
-
+Reboot your system and have fun!

+ inotify
+ a powerful yet simple file change notification system
+
+
+
+Document started 15 Mar 2005 by Robert Love <rml@novell.com>
+
+(i) User Interface
+
+Inotify is controlled by a set of three sys calls
+
+First step in using inotify is to initialise an inotify instance
+
+ int fd = inotify_init ();
+
+Change events are managed by "watches". A watch is an (object,mask) pair where
+the object is a file or directory and the mask is a bit mask of one or more
+inotify events that the application wishes to receive. See <linux/inotify.h>
+for valid events. A watch is referenced by a watch descriptor, or wd.
+
+Watches are added via a path to the file.
+
+Watches on a directory will return events on any files inside of the directory.
+
+Adding a watch is simple,
+
+ int wd = inotify_add_watch (fd, path, mask);
+
+You can add a large number of files via something like
+
+ for each file to watch {
+ int wd = inotify_add_watch (fd, file, mask);
+ }
+
+You can update an existing watch in the same manner, by passing in a new mask.
+
+An existing watch is removed via the INOTIFY_IGNORE ioctl, for example
+
+ inotify_rm_watch (fd, wd);
+
+Events are provided in the form of an inotify_event structure that is read(2)
+from a inotify instance fd. The filename is of dynamic length and follows the
+struct. It is of size len. The filename is padded with null bytes to ensure
+proper alignment. This padding is reflected in len.
+
+You can slurp multiple events by passing a large buffer, for example
+
+ size_t len = read (fd, buf, BUF_LEN);
+
+Will return as many events as are available and fit in BUF_LEN.
+
+each inotify instance fd is also select()- and poll()-able.
+
+You can find the size of the current event queue via the FIONREAD ioctl.
+
+All watches are destroyed and cleaned up on close.
+
+
+(ii) Internal Kernel Implementation
+
+Each open inotify instance is associated with an inotify_device structure.
+
+Each watch is associated with an inotify_watch structure. Watches are chained
+off of each associated device and each associated inode.
+
+See fs/inotify.c for the locking and lifetime rules.
+
+
+(iii) Rationale
+
+Q: What is the design decision behind not tying the watch to the open fd of
+ the watched object?
+
+A: Watches are associated with an open inotify device, not an open file.
+ This solves the primary problem with dnotify: keeping the file open pins
+ the file and thus, worse, pins the mount. Dnotify is therefore infeasible
+ for use on a desktop system with removable media as the media cannot be
+ unmounted.
+
+Q: What is the design decision behind using an-fd-per-device as opposed to
+ an fd-per-watch?
+
+A: An fd-per-watch quickly consumes more file descriptors than are allowed,
+ more fd's than are feasible to manage, and more fd's than are optimally
+ select()-able. Yes, root can bump the per-process fd limit and yes, users
+ can use epoll, but requiring both is a silly and extraneous requirement.
+ A watch consumes less memory than an open file, separating the number
+ spaces is thus sensible. The current design is what user-space developers
+ want: Users initialize inotify, once, and add n watches, requiring but one fd
+ and no twiddling with fd limits. Initializing an inotify instance two
+ thousand times is silly. If we can implement user-space's preferences
+ cleanly--and we can, the idr layer makes stuff like this trivial--then we
+ should.
+
+ There are other good arguments. With a single fd, there is a single
+ item to block on, which is mapped to a single queue of events. The single
+ fd returns all watch events and also any potential out-of-band data. If
+ every fd was a separate watch,
+
+ - There would be no way to get event ordering. Events on file foo and
+ file bar would pop poll() on both fd's, but there would be no way to tell
+ which happened first. A single queue trivially gives you ordering. Such
+ ordering is crucial to existing applications such as Beagle. Imagine
+ "mv a b ; mv b a" events without ordering.
+
+ - We'd have to maintain n fd's and n internal queues with state,
+ versus just one. It is a lot messier in the kernel. A single, linear
+ queue is the data structure that makes sense.
+
+ - User-space developers prefer the current API. The Beagle guys, for
+ example, love it. Trust me, I asked. It is not a surprise: Who'd want
+ to manage and block on 1000 fd's via select?
+
+ - You'd have to manage the fd's, as an example: Call close() when you
+ received a delete event.
+
+ - No way to get out of band data.
+
+ - 1024 is still too low. ;-)
+
+ When you talk about designing a file change notification system that
+ scales to 1000s of directories, juggling 1000s of fd's just does not seem
+ the right interface. It is too heavy.
+
+Q: Why the system call approach?
+
+A: The poor user-space interface is the second biggest problem with dnotify.
+ Signals are a terrible, terrible interface for file notification. Or for
+ anything, for that matter. The ideal solution, from all perspectives, is a
+ file descriptor-based one that allows basic file I/O and poll/select.
+ Obtaining the fd and managing the watches could have been done either via a
+ device file or a family of new system calls. We decided to implement a
+ family of system calls because that is the preffered approach for new kernel
+ features and it means our user interface requirements.
+
+ Additionally, it _is_ possible to more than one instance and
+ juggle more than one queue and thus more than one associated fd.

+Execute-in-place for file mappings
+----------------------------------
+
+Motivation
+----------
+File mappings are performed by mapping page cache pages to userspace. In
+addition, read&write type file operations also transfer data from/to the page
+cache.
+
+For memory backed storage devices that use the block device interface, the page
+cache pages are in fact copies of the original storage. Various approaches
+exist to work around the need for an extra copy. The ramdisk driver for example
+does read the data into the page cache, keeps a reference, and discards the
+original data behind later on.
+
+Execute-in-place solves this issue the other way around: instead of keeping
+data in the page cache, the need to have a page cache copy is eliminated
+completely. With execute-in-place, read&write type operations are performed
+directly from/to the memory backed storage device. For file mappings, the
+storage device itself is mapped directly into userspace.
+
+This implementation was initialy written for shared memory segments between
+different virtual machines on s390 hardware to allow multiple machines to
+share the same binaries and libraries.
+
+Implementation
+--------------
+Execute-in-place is implemented in three steps: block device operation,
+address space operation, and file operations.
+
+A block device operation named direct_access is used to retrieve a
+reference (pointer) to a block on-disk. The reference is supposed to be
+cpu-addressable, physical address and remain valid until the release operation
+is performed. A struct block_device reference is used to address the device,
+and a sector_t argument is used to identify the individual block. As an
+alternative, memory technology devices can be used for this.
+
+The block device operation is optional, these block devices support it as of
+today:
+- dcssblk: s390 dcss block device driver
+
+An address space operation named get_xip_page is used to retrieve reference
+to a struct page. To address the target page, a reference to an address_space,
+and a sector number is provided. A 3rd argument indicates whether the
+function should allocate blocks if needed.
+
+This address space operation is mutually exclusive with readpage&writepage that
+do page cache read/write operations.
+The following filesystems support it as of today:
+- ext2: the second extended filesystem, see Documentation/filesystems/ext2.txt
+
+A set of file operations that do utilize get_xip_page can be found in
+mm/filemap_xip.c . The following file operation implementations are provided:
+- aio_read/aio_write
+- readv/writev
+- sendfile
+
+The generic file operations do_sync_read/do_sync_write can be used to implement
+classic synchronous IO calls.
+
+Shortcomings
+------------
+This implementation is limited to storage devices that are cpu addressable at
+all times (no highmem or such). It works well on rom/ram, but enhancements are
+needed to make it work with flash in read+write mode.
+Putting the Linux kernel and/or its modules on a xip filesystem does not mean
+they are not copied.

+USERSPACE VERBS ACCESS
+
+ The ib_uverbs module, built by enabling CONFIG_INFINIBAND_USER_VERBS,
+ enables direct userspace access to IB hardware via "verbs," as
+ described in chapter 11 of the InfiniBand Architecture Specification.
+
+ To use the verbs, the libibverbs library, available from
+ <http://openib.org/>, is required. libibverbs contains a
+ device-independent API for using the ib_uverbs interface.
+ libibverbs also requires appropriate device-dependent kernel and
+ userspace driver for your InfiniBand hardware. For example, to use
+ a Mellanox HCA, you will need the ib_mthca kernel module and the
+ libmthca userspace driver be installed.
+
+User-kernel communication
+
+ Userspace communicates with the kernel for slow path, resource
+ management operations via the /dev/infiniband/uverbsN character
+ devices. Fast path operations are typically performed by writing
+ directly to hardware registers mmap()ed into userspace, with no
+ system call or context switch into the kernel.
+
+ Commands are sent to the kernel via write()s on these device files.
+ The ABI is defined in drivers/infiniband/include/ib_user_verbs.h.
+ The structs for commands that require a response from the kernel
+ contain a 64-bit field used to pass a pointer to an output buffer.
+ Status is returned to userspace as the return value of the write()
+ system call.
+
+Resource management
+
+ Since creation and destruction of all IB resources is done by
+ commands passed through a file descriptor, the kernel can keep track
+ of which resources are attached to a given userspace context. The
+ ib_uverbs module maintains idr tables that are used to translate
+ between kernel pointers and opaque userspace handles, so that kernel
+ pointers are never exposed to userspace and userspace cannot trick
+ the kernel into following a bogus pointer.
+
+ This also allows the kernel to clean up when a process exits and
+ prevent one process from touching another process's resources.
+
+Memory pinning
+
+ Direct userspace I/O requires that memory regions that are potential
+ I/O targets be kept resident at the same physical address. The
+ ib_uverbs module manages pinning and unpinning memory regions via
+ get_user_pages() and put_page() calls. It also accounts for the
+ amount of memory pinned in the process's locked_vm, and checks that
+ unprivileged processes do not exceed their RLIMIT_MEMLOCK limit.
+
+ Pages that are pinned multiple times are counted each time they are
+ pinned, so the value of locked_vm may be an overestimate of the
+ number of pages pinned by a process.
+
+/dev files
+
+ To create the appropriate character device files automatically with
+ udev, a rule like
+
+ KERNEL="uverbs*", NAME="infiniband/%k"
+
+ can be used. This will create device nodes named
+
+ /dev/infiniband/uverbs0
+
+ and so on. Since the InfiniBand userspace verbs should be safe for
+ use by non-privileged processes, it may be useful to add an
+ appropriate MODE or GROUP to the udev rule.

+Documentation for kdump - the kexec-based crash dumping solution
+================================================================
+
+DESIGN
+======
+
+Kdump uses kexec to reboot to a second kernel whenever a dump needs to be taken.
+This second kernel is booted with very little memory. The first kernel reserves
+the section of memory that the second kernel uses. This ensures that on-going
+DMA from the first kernel does not corrupt the second kernel.
+
+All the necessary information about Core image is encoded in ELF format and
+stored in reserved area of memory before crash. Physical address of start of
+ELF header is passed to new kernel through command line parameter elfcorehdr=.
+
+On i386, the first 640 KB of physical memory is needed to boot, irrespective
+of where the kernel loads. Hence, this region is backed up by kexec just before
+rebooting into the new kernel.
+
+In the second kernel, "old memory" can be accessed in two ways.
+
+- The first one is through a /dev/oldmem device interface. A capture utility
+ can read the device file and write out the memory in raw format. This is raw
+ dump of memory and analysis/capture tool should be intelligent enough to
+ determine where to look for the right information. ELF headers (elfcorehdr=)
+ can become handy here.
+
+- The second interface is through /proc/vmcore. This exports the dump as an ELF
+ format file which can be written out using any file copy command
+ (cp, scp, etc). Further, gdb can be used to perform limited debugging on
+ the dump file. This method ensures methods ensure that there is correct
+ ordering of the dump pages (corresponding to the first 640 KB that has been
+ relocated).
+
+SETUP
+=====
+
+1) Download http://www.xmission.com/~ebiederm/files/kexec/kexec-tools-1.101.tar.gz
+ and apply http://lse.sourceforge.net/kdump/patches/kexec-tools-1.101-kdump.patch
+ and after that build the source.
+
+2) Download and build the appropriate (latest) kexec/kdump (-mm) kernel
+ patchset and apply it to the vanilla kernel tree.
+
+ Two kernels need to be built in order to get this feature working.
+
+ A) First kernel:
+ a) Enable "kexec system call" feature (in Processor type and features).
+ CONFIG_KEXEC=y
+ b) This kernel's physical load address should be the default value of
+ 0x100000 (0x100000, 1 MB) (in Processor type and features).
+ CONFIG_PHYSICAL_START=0x100000
+ c) Enable "sysfs file system support" (in Pseudo filesystems).
+ CONFIG_SYSFS=y
+ d) Boot into first kernel with the command line parameter "crashkernel=Y@X".
+ Use appropriate values for X and Y. Y denotes how much memory to reserve
+ for the second kernel, and X denotes at what physical address the reserved
+ memory section starts. For example: "crashkernel=64M@16M".
+
+ B) Second kernel:
+ a) Enable "kernel crash dumps" feature (in Processor type and features).
+ CONFIG_CRASH_DUMP=y
+ b) Specify a suitable value for "Physical address where the kernel is
+ loaded" (in Processor type and features). Typically this value
+ should be same as X (See option d) above, e.g., 16 MB or 0x1000000.
+ CONFIG_PHYSICAL_START=0x1000000
+ c) Enable "/proc/vmcore support" (Optional, in Pseudo filesystems).
+ CONFIG_PROC_VMCORE=y
+ d) Disable SMP support and build a UP kernel (Until it is fixed).
+ CONFIG_SMP=n
+ e) Enable "Local APIC support on uniprocessors".
+ CONFIG_X86_UP_APIC=y
+ f) Enable "IO-APIC support on uniprocessors"
+ CONFIG_X86_UP_IOAPIC=y
+
+ Note: i) Options a) and b) depend upon "Configure standard kernel features
+ (for small systems)" (under General setup).
+ ii) Option a) also depends on CONFIG_HIGHMEM (under Processor
+ type and features).
+ iii) Both option a) and b) are under "Processor type and features".
+
+3) Boot into the first kernel. You are now ready to try out kexec-based crash
+ dumps.
+
+4) Load the second kernel to be booted using:
+
+ kexec -p <second-kernel> --crash-dump --args-linux --append="root=<root-dev>
+ init 1 irqpoll"
+
+ Note: i) <second-kernel> has to be a vmlinux image. bzImage will not work,
+ as of now.
+ ii) By default ELF headers are stored in ELF32 format (for i386). This
+ is sufficient to represent the physical memory up to 4GB. To store
+ headers in ELF64 format, specifiy "--elf64-core-headers" on the
+ kexec command line additionally.
+ iii) Specify "irqpoll" as command line parameter. This reduces driver
+ initialization failures in second kernel due to shared interrupts.
+
+5) System reboots into the second kernel when a panic occurs. A module can be
+ written to force the panic or "ALT-SysRq-c" can be used initiate a crash
+ dump for testing purposes.
+
+6) Write out the dump file using
+
+ cp /proc/vmcore <dump-file>
+
+ Dump memory can also be accessed as a /dev/oldmem device for a linear/raw
+ view. To create the device, type:
+
+ mknod /dev/oldmem c 1 12
+
+ Use "dd" with suitable options for count, bs and skip to access specific
+ portions of the dump.
+
+ Entire memory: dd if=/dev/oldmem of=oldmem.001
+
+ANALYSIS
+========
+
+Limited analysis can be done using gdb on the dump file copied out of
+/proc/vmcore. Use vmlinux built with -g and run
+
+ gdb vmlinux <dump-file>
+
+Stack trace for the task on processor 0, register display, memory display
+work fine.
+
+Note: gdb cannot analyse core files generated in ELF64 format for i386.
+
+TODO
+====
+
+1) Provide a kernel pages filtering mechanism so that core file size is not
+ insane on systems having huge memory banks.
+2) Modify "crash" tool to make it recognize this dump.

+ The semaphore could be used to govern access to the payload and to control
+ the payload pointer. It must be write-locked for modifications and would
+ have to be read-locked for general access. The disadvantage of doing this
+ is that the accessor may be required to sleep.
+
+ (3) RCU.
+
+ RCU must be used when the semaphore isn't already held; if the semaphore
+ is held then the contents can't change under you unexpectedly as the
+ semaphore must still be used to serialise modifications to the key. The
+ key management code takes care of this for the key type.
+
+ However, this means using:
+
+ rcu_read_lock() ... rcu_dereference() ... rcu_read_unlock()
+
+ to read the pointer, and:
+
+ rcu_dereference() ... rcu_assign_pointer() ... call_rcu()
+
+ to set the pointer and dispose of the old contents after a grace period.
+ Note that only the key type should ever modify a key's payload.
+
+ Furthermore, an RCU controlled payload must hold a struct rcu_head for the
+ use of call_rcu() and, if the payload is of variable size, the length of
+ the payload. key->datalen cannot be relied upon to be consistent with the
+ payload just dereferenced if the key's semaphore is not held.

+10/100 ethernet cards uses Davicom chipset too, so this driver supports CNET cards too ).If you
+didn't compile this driver as a module, it will automatically load itself on boot and print a
+line similar to :
- A-1: For normal single or multiple processor kernel
- "gcc -DMODULE -D__KERNEL__ -I/usr/src/linux/net/inet -Wall
- -Wstrict-prototypes -O6 -c dmfe.c"

+If you compiled this driver as a module, you have to load it on boot.You can load it with command :
+
+ insmod dmfe
+
+This way it will autodetect the device mode.This is the suggested way to load the module.Or you can pass
+a mode= setting to module while loading, like :
+
+ insmod dmfe mode=0 # Force 10M Half Duplex
+ insmod dmfe mode=1 # Force 100M Half Duplex
+ insmod dmfe mode=4 # Force 10M Full Duplex
+ insmod dmfe mode=5 # Force 100M Full Duplex
+
+Next you should configure your network interface with a command similar to :
+
+ ifconfig eth0 172.22.3.18
+ ^^^^^^^^^^^
+ Your IP Adress
+
+Then you may have to modify the default routing table with command :
+
+ route add default eth0
- B. The following steps teach you how to activate a DM9102 board:
-
- 1. Used the upper compiler command to compile dmfe.c
-
- 2. Insert dmfe module into kernel
- "insmod dmfe" ;;Auto Detection Mode (Suggest)
- "insmod dmfe mode=0" ;;Force 10M Half Duplex
- "insmod dmfe mode=1" ;;Force 100M Half Duplex
- "insmod dmfe mode=4" ;;Force 10M Full Duplex
- "insmod dmfe mode=5" ;;Force 100M Full Duplex
-
- 3. Config a dm9102 network interface
- "ifconfig eth0 172.22.3.18"
- ^^^^^^^^^^^ Your IP address
-
- 4. Activate the IP routing table. For some distributions, it is not
- necessary. You can type "route" to check.
-
- "route add default eth0"
+Now your ethernet card should be up and running.
- 5. Well done. Your DM9102 adapter is now activated.

+ LC-trie implementation notes.
+
+Node types
+----------
+leaf
+ An end node with data. This has a copy of the relevant key, along
+ with 'hlist' with routing table entries sorted by prefix length.
+ See struct leaf and struct leaf_info.
+
+trie node or tnode
+ An internal node, holding an array of child (leaf or tnode) pointers,
+ indexed through a subset of the key. See Level Compression.
+
+A few concepts explained
+------------------------
+Bits (tnode)
+ The number of bits in the key segment used for indexing into the
+ child array - the "child index". See Level Compression.
+
+Pos (tnode)
+ The position (in the key) of the key segment used for indexing into
+ the child array. See Path Compression.
+
+Path Compression / skipped bits
+ Any given tnode is linked to from the child array of its parent, using
+ a segment of the key specified by the parent's "pos" and "bits"
+ In certain cases, this tnode's own "pos" will not be immediately
+ adjacent to the parent (pos+bits), but there will be some bits
+ in the key skipped over because they represent a single path with no
+ deviations. These "skipped bits" constitute Path Compression.
+ Note that the search algorithm will simply skip over these bits when
+ searching, making it necessary to save the keys in the leaves to
+ verify that they actually do match the key we are searching for.
+
+Level Compression / child arrays
+ the trie is kept level balanced moving, under certain conditions, the
+ children of a full child (see "full_children") up one level, so that
+ instead of a pure binary tree, each internal node ("tnode") may
+ contain an arbitrarily large array of links to several children.
+ Conversely, a tnode with a mostly empty child array (see empty_children)
+ may be "halved", having some of its children moved downwards one level,
+ in order to avoid ever-increasing child arrays.
+
+empty_children
+ the number of positions in the child array of a given tnode that are
+ NULL.
+
+full_children
+ the number of children of a given tnode that aren't path compressed.
+ (in other words, they aren't NULL or leaves and their "pos" is equal
+ to this tnode's "pos"+"bits").
+
+ (The word "full" here is used more in the sense of "complete" than
+ as the opposite of "empty", which might be a tad confusing.)
+
+Comments
+---------
+
+We have tried to keep the structure of the code as close to fib_hash as
+possible to allow verification and help up reviewing.
+
+fib_find_node()
+ A good start for understanding this code. This function implements a
+ straightforward trie lookup.
+
+fib_insert_node()
+ Inserts a new leaf node in the trie. This is bit more complicated than
+ fib_find_node(). Inserting a new node means we might have to run the
+ level compression algorithm on part of the trie.
+
+trie_leaf_remove()
+ Looks up a key, deletes it and runs the level compression algorithm.
+
+trie_rebalance()
+ The key function for the dynamic trie after any change in the trie
+ it is run to optimize and reorganize. Tt will walk the trie upwards
+ towards the root from a given tnode, doing a resize() at each step
+ to implement level compression.
+
+resize()
+ Analyzes a tnode and optimizes the child array size by either inflating
+ or shrinking it repeatedly until it fullfills the criteria for optimal
+ level compression. This part follows the original paper pretty closely
+ and there may be some room for experimentation here.
+
+inflate()
+ Doubles the size of the child array within a tnode. Used by resize().
+
+halve()
+ Halves the size of the child array within a tnode - the inverse of
+ inflate(). Used by resize();
+
+fn_trie_insert(), fn_trie_delete(), fn_trie_select_default()
+ The route manipulation functions. Should conform pretty closely to the
+ corresponding functions in fib_hash.
+
+fn_trie_flush()
+ This walks the full trie (using nextleaf()) and searches for empty
+ leaves which have to be removed.
+
+fn_trie_dump()
+ Dumps the routing table ordered by prefix length. This is somewhat
+ slower than the corresponding fib_hash function, as we have to walk the
+ entire trie for each prefix length. In comparison, fib_hash is organized
+ as one "zone"/hash per prefix length.
+
+Locking
+-------
+
+fib_lock is used for an RW-lock in the same way that this is done in fib_hash.
+However, the functions are somewhat separated for other possible locking
+scenarios. It might conceivably be possible to run trie_rebalance via RCU
+to avoid read_lock in the fn_trie_lookup() function.
+
+Main lookup mechanism
+---------------------
+fn_trie_lookup() is the main lookup function.
+
+The lookup is in its simplest form just like fib_find_node(). We descend the
+trie, key segment by key segment, until we find a leaf. check_leaf() does
+the fib_semantic_match in the leaf's sorted prefix hlist.
+
+If we find a match, we are done.
+
+If we don't find a match, we enter prefix matching mode. The prefix length,
+starting out at the same as the key length, is reduced one step at a time,
+and we backtrack upwards through the trie trying to find a longest matching
+prefix. The goal is always to reach a leaf and get a positive result from the
+fib_semantic_match mechanism.
+
+Inside each tnode, the search for longest matching prefix consists of searching
+through the child array, chopping off (zeroing) the least significant "1" of
+the child index until we find a match or the child index consists of nothing but
+zeros.
+
+At this point we backtrack (t->stats.backtrack++) up the trie, continuing to
+chop off part of the key in order to find the longest matching prefix.
+
+At this point we will repeatedly descend subtries to look for a match, and there
+are some optimizations available that can provide us with "shortcuts" to avoid
+descending into dead ends. Look for "HL_OPTIMIZE" sections in the code.
+
+To alleviate any doubts about the correctness of the route selection process,
+a new netlink operation has been added. Look for NETLINK_FIB_LOOKUP, which
+gives userland access to fib_lookup().

+- Congestion control
+- How the new TCP output machine [nyi] works
+
+Congestion control
+==================
+
+The following variables are used in the tcp_sock for congestion control:
+snd_cwnd The size of the congestion window
+snd_ssthresh Slow start threshold. We are in slow start if
+ snd_cwnd is less than this.
+snd_cwnd_cnt A counter used to slow down the rate of increase
+ once we exceed slow start threshold.
+snd_cwnd_clamp This is the maximum size that snd_cwnd can grow to.
+snd_cwnd_stamp Timestamp for when congestion window last validated.
+snd_cwnd_used Used as a highwater mark for how much of the
+ congestion window is in use. It is used to adjust
+ snd_cwnd down when the link is limited by the
+ application rather than the network.
+
+As of 2.6.13, Linux supports pluggable congestion control algorithms.
+A congestion control mechanism can be registered through functions in
+tcp_cong.c. The functions used by the congestion control mechanism are
+registered via passing a tcp_congestion_ops struct to
+tcp_register_congestion_control. As a minimum name, ssthresh,
+cong_avoid, min_cwnd must be valid.
+
+Private data for a congestion control mechanism is stored in tp->ca_priv.
+tcp_ca(tp) returns a pointer to this space. This is preallocated space - it
+is important to check the size of your private data will fit this space, or
+alternatively space could be allocated elsewhere and a pointer to it could
+be stored here.
+
+There are three kinds of congestion control algorithms currently: The
+simplest ones are derived from TCP reno (highspeed, scalable) and just
+provide an alternative the congestion window calculation. More complex
+ones like BIC try to look at other events to provide better
+heuristics. There are also round trip time based algorithms like
+Vegas and Westwood+.
+
+Good TCP congestion control is a complex problem because the algorithm
+needs to maintain fairness and performance. Please review current
+research and RFC's before developing new modules.
+
+The method that is used to determine which congestion control mechanism is
+determined by the setting of the sysctl net.ipv4.tcp_congestion_control.
+The default congestion control will be the last one registered (LIFO);
+so if you built everything as modules. the default will be reno. If you
+build with the default's from Kconfig, then BIC will be builtin (not a module)
+and it will end up the default.
+
+If you really want a particular default value then you will need
+to set it with the sysctl. If you use a sysctl, the module will be autoloaded
+if needed and you will get the expected protocol. If you ask for an
+unknown congestion method, then the sysctl attempt will fail.
+
+If you remove a tcp congestion control module, then you will get the next
+available one. Since reno can not be built as a module, and can not be
+deleted, it will always be available.

-Linux WAN Router Utilities Package
-------------------------------------------------------------------------------
-Version 2.2.1

-INTRODUCTION
-
-Wide Area Networks (WANs) are used to interconnect Local Area Networks (LANs)
-and/or stand-alone hosts over vast distances with data transfer rates
-significantly higher than those achievable with commonly used dial-up
-connections.
-
-Usually an external device called `WAN router' sitting on your local network
-or connected to your machine's serial port provides physical connection to
-WAN. Although router's job may be as simple as taking your local network
-traffic, converting it to WAN format and piping it through the WAN link, these
-devices are notoriously expensive, with prices as much as 2 - 5 times higher
-then the price of a typical PC box.
-
-Alternatively, considering robustness and multitasking capabilities of Linux,
-an internal router can be built (most routers use some sort of stripped down
-Unix-like operating system anyway). With a number of relatively inexpensive WAN
-interface cards available on the market, a perfectly usable router can be
-built for less than half a price of an external router. Yet a Linux box
-acting as a router can still be used for other purposes, such as fire-walling,
-running FTP, WWW or DNS server, etc.
-
-This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux
-operating system and provides generic hardware-independent services for such
-drivers. Why can existing Linux network device interface not be used for
-this purpose? Well, it can. However, there are a few key differences between
-a typical network interface (e.g. Ethernet) and a WAN link.
-
-Many WAN protocols, such as X.25 and frame relay, allow for multiple logical
-connections (known as `virtual circuits' in X.25 terminology) over a single
-physical link. Each such virtual circuit may (and almost always does) lead
-to a different geographical location and, therefore, different network. As a
-result, it is the virtual circuit, not the physical link, that represents a
-route and, therefore, a network interface in Linux terms.
-
-To further complicate things, virtual circuits are usually volatile in nature
-(excluding so called `permanent' virtual circuits or PVCs). With almost no
-time required to set up and tear down a virtual circuit, it is highly desirable
-to implement on-demand connections in order to minimize network charges. So
-unlike a typical network driver, the WAN driver must be able to handle multiple
-network interfaces and cope as multiple virtual circuits come into existence
-and go away dynamically.
-
-Last, but not least, WAN configuration is much more complex than that of say
-Ethernet and may well amount to several dozens of parameters. Some of them
-are "link-wide" while others are virtual circuit-specific. The same holds
-true for WAN statistics which is by far more extensive and extremely useful
-when troubleshooting WAN connections. Extending the ifconfig utility to suit
-these needs may be possible, but does not seem quite reasonable. Therefore, a
-WAN configuration utility and corresponding application programmer's interface
-is needed for this purpose.
-
-Most of these problems are taken care of by this module. Its goal is to
-provide a user with more-or-less standard look and feel for all WAN devices and
-assist a WAN device driver writer by providing common services, such as:
-
- o User-level interface via /proc file system
- o Centralized configuration
- o Device management (setup, shutdown, etc.)
- o Network interface management (dynamic creation/destruction)
- o Protocol encapsulation/decapsulation
-
-To ba able to use the Linux WAN Router you will also need a WAN Tools package
-available from
-
- ftp.sangoma.com/pub/linux/current_wanpipe/wanpipe-X.Y.Z.tgz
-
-where vX.Y.Z represent the wanpipe version number.

-ACKNOWLEDGEMENTS
-
-This product is based on the WANPIPE(tm) Multiprotocol WAN Router developed
-by Sangoma Technologies Inc. for Linux 2.0.x and 2.2.x. Success of the WANPIPE
-together with the next major release of Linux kernel in summer 1996 commanded
-adequate changes to the WANPIPE code to take full advantage of new Linux
-features.
-
-Instead of continuing developing proprietary interface tied to Sangoma WAN
-cards, we decided to separate all hardware-independent code into a separate
-module and defined two levels of interfaces - one for user-level applications
-and another for kernel-level WAN drivers. WANPIPE is now implemented as a
-WAN driver compliant with the WAN Link Driver interface. Also a general
-purpose WAN configuration utility and a set of shell scripts was developed to
-support WAN router at the user level.
-
-Many useful ideas concerning hardware-independent interface implementation
-were given by Mike McLagan <mike.mclagan@linux.org> and his implementation
-of the Frame Relay router and drivers for Sangoma cards (dlci/sdla).
-
-With the new implementation of the APIs being incorporated into the WANPIPE,
-a special thank goes to Alan Cox in providing insight into BSD sockets.
-
-Special thanks to all the WANPIPE users who performed field-testing, reported
-bugs and made valuable comments and suggestions that help us to improve this
-product.
-
-
-
-NEW IN THIS RELEASE
-
- o Updated the WANCFG utility
- Calls the pppconfig to configure the PPPD
- for async connections.
-
- o Added the PPPCONFIG utility
- Used to configure the PPPD dameon for the
- WANPIPE Async PPP and standard serial port.
- The wancfg calls the pppconfig to configure
- the pppd.
-
- o Fixed the PCI autodetect feature.
- The SLOT 0 was used as an autodetect option
- however, some high end PC's slot numbers start
- from 0.
-
- o This release has been tested with the new backupd
- daemon release.

-
-beta-2.1.4 Jul 2000 o Dynamic interface configuration:
- Network interfaces reflect the state
- of protocol layer. If the protocol becomes
- disconnected, driver will bring down
- the interface. Once the protocol reconnects
- the interface will be brought up.
-
- Note: This option is turned off by default.
-
- o Dynamic wanrouter setup using 'wanconfig':
- wanconfig utility can be used to
- shutdown,restart,start or reconfigure
- a virtual circuit dynamically.
-
- Frame Relay: Each DLCI can be:
- created,stopped,restarted and reconfigured
- dynamically using wanconfig.
-
- ex: wanconfig card wanpipe1 dev wp1_fr16 up
-
- o Wanrouter startup via command line arguments:
- wanconfig also supports wanrouter startup via command line
- arguments. Thus, there is no need to create a wanpipe#.conf
- configuration file.
-
- o Socket based x25api update/bug fixes.
- Added support for LCN numbers greater than 255.
- Option to pass up modem messages.
- Provided a PCI IRQ check, so a single S514
- card is guaranteed to have a non-sharing interrupt.
-
- o Fixes to the wancfg utility.
- o New FT1 debugging support via *pipemon utilities.
- o Frame Relay ARP support Enabled.
-
-beta3-2.1.4 Jul 2000 o X25 M_BIT Problem fix.
- o Added the Multi-Port PPP
- Updated utilites for the Multi-Port PPP.
-
-2.1.4 Aut 2000
- o In X25API:
- Maximum packet an application can send
- to the driver has been extended to 4096 bytes.
-
- Fixed the x25 startup bug. Enable
- communications only after all interfaces
- come up. HIGH SVC/PVC is used to calculate
- the number of channels.
- Enable protocol only after all interfaces
- are enabled.
-
- o Added an extra state to the FT1 config, kernel module.
- o Updated the pipemon debuggers.
-
- o Blocked the Multi-Port PPP from running on kernels
- 2.2.16 or greater, due to syncppp kernel module
- change.
-
-beta1-2.1.5 Nov 15 2000
- o Fixed the MulitPort PPP Support for kernels 2.2.16 and above.
- 2.2.X kernels only
-
- o Secured the driver UDP debugging calls
- - All illegal netowrk debugging calls are reported to
- the log.
- - Defined a set of allowed commands, all other denied.
-
- o Cpipemon
- - Added set FT1 commands to the cpipemon. Thus CSU/DSU
- configuraiton can be performed using cpipemon.
- All systems that cannot run cfgft1 GUI utility should
- use cpipemon to configure the on board CSU/DSU.
-
-
- o Keyboard Led Monitor/Debugger
- - A new utilty /usr/sbin/wpkbdmon uses keyboard leds
- to convey operatinal statistic information of the
- Sangoma WANPIPE cards.
- NUM_LOCK = Line State (On=connected, Off=disconnected)
- CAPS_LOCK = Tx data (On=transmitting, Off=no tx data)
- SCROLL_LOCK = Rx data (On=receiving, Off=no rx data
-
- o Hardware probe on module load and dynamic device allocation
- - During WANPIPE module load, all Sangoma cards are probed
- and found information is printed in the /var/log/messages.
- - If no cards are found, the module load fails.
- - Appropriate number of devices are dynamically loaded
- based on the number of Sangoma cards found.
-
- Note: The kernel configuraiton option
- CONFIG_WANPIPE_CARDS has been taken out.
-
- o Fixed the Frame Relay and Chdlc network interfaces so they are
- compatible with libpcap libraries. Meaning, tcpdump, snort,
- ethereal, and all other packet sniffers and debuggers work on
- all WANPIPE netowrk interfaces.
- - Set the network interface encoding type to ARPHRD_PPP.
- This tell the sniffers that data obtained from the
- network interface is in pure IP format.
- Fix for 2.2.X kernels only.
-
- o True interface encoding option for Frame Relay and CHDLC
- - The above fix sets the network interface encoding
- type to ARPHRD_PPP, however some customers use
- the encoding interface type to determine the
- protocol running. Therefore, the TURE ENCODING
- option will set the interface type back to the
- original value.
-
- NOTE: If this option is used with Frame Relay and CHDLC
- libpcap library support will be broken.
- i.e. tcpdump will not work.
- Fix for 2.2.x Kernels only.
-
- o Ethernet Bridgind over Frame Relay
- - The Frame Relay bridging has been developed by
- Kristian Hoffmann and Mark Wells.
- - The Linux kernel bridge is used to send ethernet
- data over the frame relay links.
- For 2.2.X Kernels only.
-
- o Added extensive 2.0.X support. Most new features of
- 2.1.5 for protocols Frame Relay, PPP and CHDLC are
- supported under 2.0.X kernels.
-
-beta1-2.2.0 Dec 30 2000
- o Updated drivers for 2.4.X kernels.
- o Updated drivers for SMP support.
- o X25API is now able to share PCI interrupts.
- o Took out a general polling routine that was used
- only by X25API.
- o Added appropriate locks to the dynamic reconfiguration
- code.
- o Fixed a bug in the keyboard debug monitor.
-
-beta2-2.2.0 Jan 8 2001
- o Patches for 2.4.0 kernel
- o Patches for 2.2.18 kernel
- o Minor updates to PPP and CHLDC drivers.
- Note: No functinal difference.
-
-beta3-2.2.9 Jan 10 2001
- o I missed the 2.2.18 kernel patches in beta2-2.2.0
- release. They are included in this release.
-
-Stable Release
-2.2.0 Feb 01 2001
- o Bug fix in wancfg GUI configurator.
- The edit function didn't work properly.
-
-
-bata1-2.2.1 Feb 09 2001
- o WANPIPE TTY Driver emulation.
- Two modes of operation Sync and Async.
- Sync: Using the PPPD daemon, kernel SyncPPP layer
- and the Wanpipe sync TTY driver: a PPP protocol
- connection can be established via Sangoma adapter, over
- a T1 leased line.
-
- The 2.4.0 kernel PPP layer supports MULTILINK
- protocol, that can be used to bundle any number of Sangoma
- adapters (T1 lines) into one, under a single IP address.
- Thus, efficiently obtaining multiple T1 throughput.
-
- NOTE: The remote side must also implement MULTILINK PPP
- protocol.
-
- Async:Using the PPPD daemon, kernel AsyncPPP layer
- and the WANPIPE async TTY driver: a PPP protocol
- connection can be established via Sangoma adapter and
- a modem, over a telephone line.
-
- Thus, the WANPIPE async TTY driver simulates a serial
- TTY driver that would normally be used to interface the
- MODEM to the linux kernel.
-
- o WANPIPE PPP Backup Utility
- This utility will monitor the state of the PPP T1 line.
- In case of failure, a dial up connection will be established
- via pppd daemon, ether via a serial tty driver (serial port),
- or a WANPIPE async TTY driver (in case serial port is unavailable).
-
- Furthermore, while in dial up mode, the primary PPP T1 link
- will be monitored for signs of life.
-
- If the PPP T1 link comes back to life, the dial up connection
- will be shutdown and T1 line re-established.
-
-
- o New Setup installation script.
- Option to UPGRADE device drivers if the kernel source has
- already been patched with WANPIPE.
-
- Option to COMPILE WANPIPE modules against the currently
- running kernel, thus no need for manual kernel and module
- re-compilatin.
-
- o Updates and Bug Fixes to wancfg utility.
-
-bata2-2.2.1 Feb 20 2001
-
- o Bug fixes to the CHDLC device drivers.
- The driver had compilation problems under kernels
- 2.2.14 or lower.
-
- o Bug fixes to the Setup installation script.
- The device drivers compilation options didn't work
- properly.
-
- o Update to the wpbackupd daemon.
- Optimized the cross-over times, between the primary
- link and the backup dialup.
-
-beta3-2.2.1 Mar 02 2001
- o Patches for 2.4.2 kernel.
-
- o Bug fixes to util/ make files.
- o Bug fixes to the Setup installation script.
-
- o Took out the backupd support and made it into
- as separate package.
-
-beta4-2.2.1 Mar 12 2001
-
- o Fix to the Frame Relay Device driver.
- IPSAC sends a packet of zero length
- header to the frame relay driver. The
- driver tries to push its own 2 byte header
- into the packet, which causes the driver to
- crash.
-
- o Fix the WANPIPE re-configuration code.
- Bug was found by trying to run the cfgft1 while the
- interface was already running.
-
- o Updates to cfgft1.
- Writes a wanpipe#.cfgft1 configuration file
- once the CSU/DSU is configured. This file can
- holds the current CSU/DSU configuration.

+Matching of PCMCIA devices to drivers is done using one or more of the
+following criteria:
+
+- manufactor ID
+- card ID
+- product ID strings _and_ hashes of these strings
+- function ID
+- device function (actual and pseudo)
+
+You should use the helpers in include/pcmcia/device_id.h for generating the
+struct pcmcia_device_id[] entries which match devices to drivers.
+
+If you want to match product ID strings, you also need to pass the crc32
+hashes of the string to the macro, e.g. if you want to match the product ID
+string 1, you need to use
+
+PCMCIA_DEVICE_PROD_ID1("some_string", 0x(hash_of_some_string)),
+
+If the hash is incorrect, the kernel will inform you about this in "dmesg"
+upon module initialization, and tell you of the correct hash.
+
+You can determine the hash of the product ID strings by catting the file
+"modalias" in the sysfs directory of the PCMCIA device. It generates a string
+in the following form:
+pcmcia:m0149cC1ABf06pfn00fn00pa725B842DpbF1EFEE84pc0877B627pd00000000
+
+The hex value after "pa" is the hash of product ID string 1, after "pb" for
+string 2 and so on.
+
+Alternatively, you can use this small tool to determine the crc32 hash.
+simply pass the string you want to evaluate as argument to this program,
+e.g.
+$ ./crc32hash "Dual Speed"
+

+/* crc32hash.c - derived from linux/lib/crc32.c, GNU GPL v2 */

+This file details changes in 2.6 which affect PCMCIA card driver authors:
+
+* event handler initialization in struct pcmcia_driver (as of 2.6.13)
+ The event handler is notified of all events, and must be initialized
+ as the event() callback in the driver's struct pcmcia_driver.
+
+* pcmcia/version.h should not be used (as of 2.6.13)
+ This file will be removed eventually.
+
+* in-kernel device<->driver matching (as of 2.6.13)
+ PCMCIA devices and their correct drivers can now be matched in
+ kernelspace. See 'devicetable.txt' for details.
+
+* Device model integration (as of 2.6.11)
+ A struct pcmcia_device is registered with the device model core,
+ and can be used (e.g. for SET_NETDEV_DEV) by using
+ handle_to_dev(client_handle_t * handle).
+
+* Convert internal I/O port addresses to unsigned long (as of 2.6.11)
+ ioaddr_t should be replaced by kio_addr_t in PCMCIA card drivers.
+
+* irq_mask and irq_list parameters (as of 2.6.11)
+ The irq_mask and irq_list parameters should no longer be used in
+ PCMCIA card drivers. Instead, it is the job of the PCMCIA core to
+ determine which IRQ should be used. Therefore, link->irq.IRQInfo2
+ is ignored.
+
+* client->PendingEvents is gone (as of 2.6.11)

+
+ resume(): devices are woken up so that system can continue
+
+ thaw all user processes
+
+Q: What is this 'Encrypt suspend image' for?
+
+A: First of all: it is not a replacement for dm-crypt encrypted swap.
+It cannot protect your computer while it is suspended. Instead it does
+protect from leaking sensitive data after resume from suspend.
+
+Think of the following: you suspend while an application is running
+that keeps sensitive data in memory. The application itself prevents
+the data from being swapped out. Suspend, however, must write these
+data to swap to be able to resume later on. Without suspend encryption
+your sensitive data are then stored in plaintext on disk. This means
+that after resume your sensitive data are accessible to all
+applications having direct access to the swap device which was used
+for suspend. If you don't need swap after resume these data can remain
+on disk virtually forever. Thus it can happen that your system gets
+broken in weeks later and sensitive data which you thought were
+encrypted and protected are retrieved and stolen from the swap device.
+To prevent this situation you should use 'Encrypt suspend image'.
+
+During suspend a temporary key is created and this key is used to
+encrypt the data written to disk. When, during resume, the data was
+read back into memory the temporary key is destroyed which simply
+means that all data written to disk during suspend are then
+inaccessible so they can't be stolen later on. The only thing that
+you must then take care of is that you call 'mkswap' for the swap
+partition used for suspend as early as possible during regular
+boot. This asserts that any temporary key from an oopsed suspend or
+from a failed or aborted resume is erased from the swap device.
+
+As a rule of thumb use encrypted swap to protect your data while your
+system is shut down or suspended. Additionally use the encrypted
+suspend image to prevent sensitive data from being stolen after
+resume.

-</TABLE>
-<P>
-The minimum and maximum sizes listed for a capture device do not imply all
-that all height/width ratios or sizes within the range are possible. A
-request to set a size will be honoured by the largest available capture
-size whose capture is no large than the requested rectangle in either
-direction. For example the quickcam has 3 fixed settings.
-<P>
-<H3>Frame Buffer</H3>
-Capture cards that drop data directly onto the frame buffer must be told the
-base address of the frame buffer, its size and organisation. This is a
-privileged ioctl and one that eventually X itself should set.
-<P>
-The <b>VIDIOCSFBUF</b> ioctl sets the frame buffer parameters for a capture
-card. If the card does not do direct writes to the frame buffer then this
-ioctl will be unsupported. The <b>VIDIOCGFBUF</b> ioctl returns the
-currently used parameters. The structure used in both cases is a
-<b>struct video_buffer</b>.

-<P>
-Note that these values reflect the physical layout of the frame buffer.
-The visible area may be smaller. In fact under XFree86 this is commonly the
-case. XFree86 DGA can provide the parameters required to set up this ioctl.
-Setting the base address to NULL indicates there is no physical frame buffer
-access.
-<P>
-<H3>Capture Windows</H3>
-The capture area is described by a <b>struct video_window</b>. This defines
-a capture area and the clipping information if relevant. The
-<b>VIDIOCGWIN</b> ioctl recovers the current settings and the
-<b>VIDIOCSWIN</b> sets new values. A successful call to <b>VIDIOCSWIN</b>
-indicates that a suitable set of parameters have been chosen. They do not
-indicate that exactly what was requested was granted. The program should
-call <b>VIDIOCGWIN</b> to check if the nearest match was suitable. The
-<b>struct video_window</b> contains the following fields.

-<P>
-Merely setting the window does not enable capturing. Overlay capturing
-(i.e. PCI-PCI transfer to the frame buffer of the video card)
-is activated by passing the <b>VIDIOCCAPTURE</b> ioctl a value of 1, and
-disabled by passing it a value of 0.

-Some capture devices can capture a subfield of the image they actually see.
-This is indicated when VIDEO_TYPE_SUBCAPTURE is defined.

-must set the channel field to the channel that is being queried. On return
-the <b>struct video_channel</b> is filled in with information about the
-nature of the channel itself.
-<P>
-The <b>VIDIOCSCHAN</b> ioctl takes an integer argument and switches the

-<P>
-<H3>Reading Images</H3>
-Each call to the <b>read</b> syscall returns the next available image
-from the device. It is up to the caller to set format and size (using
-the VIDIOCSPICT and VIDIOCSWIN ioctls) and then to pass a suitable
-size buffer and length to the function. Not all devices will support
-read operations.
-<P>
-A second way to handle image capture is via the mmap interface if supported.
-To use the mmap interface a user first sets the desired image size and depth
-properties. Next the VIDIOCGMBUF ioctl is issued. This reports the size
-of buffer to mmap and the offset within the buffer for each frame. The
-number of frames supported is device dependent and may only be one.
-<P>
-The video_mbuf structure contains the following fields
-<P>
-<TABLE>
-<TR><TD><b>size</b><TD>The number of bytes to map</TD>
-<TR><TD><b>frames</b><TD>The number of frames</TD>
-<TR><TD><b>offsets</b><TD>The offset of each frame</TD>
-</TABLE>
-<P>
-Once the mmap has been made the VIDIOCMCAPTURE ioctl starts the
-capture to a frame using the format and image size specified in the
-video_mmap (which should match or be below the initial query size).
-When the VIDIOCMCAPTURE ioctl returns the frame is <em>not</em>
-captured yet, the driver just instructed the hardware to start the
-capture. The application has to use the VIDIOCSYNC ioctl to wait
-until the capture of a frame is finished. VIDIOCSYNC takes the frame
-number you want to wait for as argument.
-<p>
-It is allowed to call VIDIOCMCAPTURE multiple times (with different
-frame numbers in video_mmap->frame of course) and thus have multiple
-outstanding capture requests. A simple way do to double-buffering
-using this feature looks like this:
-<pre>
-/* setup everything */
-VIDIOCMCAPTURE(0)
-while (whatever) {
- VIDIOCMCAPTURE(1)
- VIDIOCSYNC(0)
- /* process frame 0 while the hardware captures frame 1 */
- VIDIOCMCAPTURE(0)
- VIDIOCSYNC(1)
- /* process frame 1 while the hardware captures frame 0 */
-}
-</pre>
-Note that you are <em>not</em> limited to only two frames. The API
-allows up to 32 frames, the VIDIOCGMBUF ioctl returns the number of
-frames the driver granted. Thus it is possible to build deeper queues
-to avoid loosing frames on load peaks.
-<p>
-While capturing to memory the driver will make a "best effort" attempt
-to capture to screen as well if requested. This normally means all
-frames that "miss" memory mapped capture will go to the display.
-<P>
-A final ioctl exists to allow a device to obtain related devices if a
-driver has multiple components (for example video0 may not be associated
-with vbi0 which would cause an intercast display program to make a bad
-mistake). The VIDIOCGUNIT ioctl reports the unit numbers of the associated
-devices if any exist. The video_unit structure has the following fields.
-<P>
-<TABLE>
-<TR><TD><b>video</b><TD>Video capture device</TD>
-<TR><TD><b>vbi</b><TD>VBI capture device</TD>

-<P>
-<H3>RDS Datastreams</H3>
-For radio devices that support it, it is possible to receive Radio Data
-System (RDS) data by means of a read() on the device. The data is packed in
-groups of three, as follows:
-<TABLE>
-<TR><TD>First Octet</TD><TD>Least Significant Byte of RDS Block</TD></TR>

+ Register 24'h20004 PCI Interrupt Status
+ bit [18] IR_SMP_INT Set when 32 input samples have been collected over
+ gpio[16] pin into GP_SAMPLE register.
+
+What's missing from the data sheet:
+
+Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
+compat remote)
+set register 0x35C050 to 0xa80a80
+
+enable sampling
+set register 0x35C054 to 0x5
+
+Of course, enable the IRQ bit 18 in the interrupt mask register .(and
+provide for a handler)
+
+GP_SAMPLE register is at 0x35C058
+
+Bits are then right shifted into the GP_SAMPLE register at the specified
+rate; you get an interrupt when a full DWORD is recieved.
+You need to recover the actual RC5 bits out of the (oversampled) IR sensor
+bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data) An
+actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
+
+I'm pretty sure when no IR signal is present the receiver is always in a
+marking state(1); but stray light, etc can cause intermittent noise values
+as well. Remember, this is a free running sample of the IR receiver state
+over time, so don't assume any sample starts at any particular place.
+
+http://www.atmel.com/dyn/resources/prod_documents/doc2817.pdf
+This data sheet (google search) seems to have a lovely description of the
+RC5 basics
+
+http://users.pandora.be/nenya/electronics/rc5/ and more data
+
+http://www.ee.washington.edu/circuit_archive/text/ir_decode.txt

+ help
+ Select this option if you want to disable continuous timer ticks
+ and have them programmed to occur as required. This option saves
+ power as the system can remain in idle state for longer.
+
+ By default dynamic tick is disabled during the boot, and can be
+ manually enabled with:
+
+ echo 1 > /sys/devices/system/timer/timer0/dyn_tick
+
+ Alternatively, if you want dynamic tick automatically enabled
+ during boot, pass "dyntick=enable" via the kernel command string.
+
+ Please note that dynamic tick may affect the accuracy of
+ timekeeping on some platforms depending on the implementation.
+ Currently at least OMAP platform is known to have accurate
+ timekeeping with dynamic tick.

- 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
- multiplies two u32 integers MULTIPLER and MULTIPLICAND,
- and generates a two-part u32 product in HIGH_PROD and
- LOW_PROD.
-
- 2) __umulsidi3(a,b) multiplies two u32 integers A and B,
- and returns a u64 product. This is just a variant of umul_ppmm.
-
- 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
- denominator) divides a two-word unsigned integer, composed by the
- integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
- places the quotient in QUOTIENT and the remainder in REMAINDER.
- HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
- If, in addition, the most significant bit of DENOMINATOR must be 1,
- then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
-
- 4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
- denominator). Like udiv_qrnnd but the numbers are signed. The
- quotient is rounded towards 0.
-
- 5) count_leading_zeros(count, x) counts the number of zero-bits from
- the msb to the first non-zero bit. This is the number of steps X
- needs to be shifted left to set the msb. Undefined for X == 0.
-
- 6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
- high_addend_2, low_addend_2) adds two two-word unsigned integers,
- composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
- LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and
- LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is
- lost.
-
- 7) sub_ddmmss(high_difference, low_difference, high_minuend,
- low_minuend, high_subtrahend, low_subtrahend) subtracts two
- two-word unsigned integers, composed by HIGH_MINUEND_1 and
- LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
- respectively. The result is placed in HIGH_DIFFERENCE and
- LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
- and is lost.

- * PIC AS DEVICE ZERO
- * ------------------
- *
- * PIC handles PCI/X busses. PCI/X requires that the 'bridge' (i.e. PIC)
- * be designated as 'device 0'. That is a departure from earlier SGI
- * PCI bridges. Because of that we use config space 1 to access the
- * config space of the first actual PCI device on the bus.
- * Here's what the PIC manual says:
- *
- * The current PCI-X bus specification now defines that the parent
- * hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
- * reduced the total number of devices from 8 to 4 and removed the
- * device registers and windows, now only supporting devices 0,1,2, and
- * 3. PIC did leave all 8 configuration space windows. The reason was
- * there was nothing to gain by removing them. Here in lies the problem.
- * The device numbering we do using 0 through 3 is unrelated to the device
- * numbering which PCI-X requires in configuration space. In the past we
- * correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
- * PCI-X requires we start a 1, not 0 and currently the PX brick
- * does associate our:
- *
- * device 0 with configuration space window 1,
- * device 1 with configuration space window 2,
- * device 2 with configuration space window 3,
- * device 3 with configuration space window 4.
- *
- * The net effect is that all config space access are off-by-one with
- * relation to other per-slot accesses on the PIC.
- * Here is a table that shows some of that:
- *
- * Internal Slot#
- * |
- * | 0 1 2 3
- * ----------|---------------------------------------
- * config | 0x21000 0x22000 0x23000 0x24000
- * |
- * even rrb | 0[0] n/a 1[0] n/a [] == implied even/odd
- * |
- * odd rrb | n/a 0[1] n/a 1[1]
- * |
- * int dev | 00 01 10 11
- * |
- * ext slot# | 1 2 3 4

+ kexec is a system call that implements the ability to shutdown your

+ you can start any kernel with it, not just Linux.
+
+ The name comes from the similiarity to the exec system call.
+
+ It is an ongoing process to be certain the hardware in a machine
+ is properly shutdown, so do not be surprised if this code does not
+ initially work for you. It may help to enable device hotplugging
+ support. As of this writing the exact hardware interface is
+ strongly in flux, so no good recommendation can be made.

- ---help---
- If you intend to attach a printer to the parallel port of your Linux
- box (as opposed to using a serial printer; if the connector at the
- printer has 9 or 25 holes ["female"], then it's serial), say Y.
- Also read the Printing-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- It is possible to share one parallel port among several devices
- (e.g. printer and ZIP drive) and it is safe to compile the
- corresponding drivers into the kernel. If you want to compile this
- driver as a module however, choose M here and read
- <file:Documentation/parport.txt>. The module will be called lp.
-
- If you have several parallel ports, you can specify which ports to
- use with the "lp" kernel command line option. (Try "man bootparam"
- or see the documentation of your boot loader (silo) about how to pass
- options to the kernel at boot time.) The syntax of the "lp" command
- line option can be found in <file:drivers/char/lp.c>.
-
- If you have more than 8 printers, you need to increase the LP_NO
- macro in lp.c and the PARPORT_MAX macro in parport.h.

+ * Double exception vector (Exceptions with PS.EXCM == 1)
+ * We get this exception when another exception occurs while were are
+ * already in an exception, such as window overflow/underflow exception,
+ * or 'expected' exceptions, for example memory exception when we were trying
+ * to read data from an invalid address in user space.
+ *
+ * Note that this vector is never invoked for level-1 interrupts, because such
+ * interrupts are disabled (masked) when PS.EXCM is set.
+ *
+ * We decode the exception and take the appropriate action. However, the
+ * double exception vector is much more careful, because a lot more error
+ * cases go through the double exception vector than through the user and
+ * kernel exception vectors.
+ *
+ * Occasionally, the kernel expects a double exception to occur. This usually
+ * happens when accessing user-space memory with the user's permissions
+ * (l32e/s32e instructions). The kernel state, though, is not always suitable
+ * for immediate transfer of control to handle_double, where "normal" exception
+ * processing occurs. Also in kernel mode, TLB misses can occur if accessing
+ * vmalloc memory, possibly requiring repair in a double exception handler.
+ *
+ * The variable at TABLE_FIXUP offset from the pointer in EXCSAVE_1 doubles as
+ * a boolean variable and a pointer to a fixup routine. If the variable
+ * EXC_TABLE_FIXUP is non-zero, this handler jumps to that address. A value of
+ * zero indicates to use the default kernel/user exception handler.
+ * There is only one exception, when the value is identical to the exc_table
+ * label, the kernel is in trouble. This mechanism is used to protect critical
+ * sections, mainly when the handler writes to the stack to assert the stack
+ * pointer is valid. Once the fixup/default handler leaves that area, the
+ * EXC_TABLE_FIXUP variable is reset to the fixup handler or zero.
+ *
+ * Procedures wishing to use this mechanism should set EXC_TABLE_FIXUP to the
+ * nonzero address of a fixup routine before it could cause a double exception
+ * and reset it before it returns.
+ *
+ * Some other things to take care of when a fast exception handler doesn't
+ * specify a particular fixup handler but wants to use the default handlers:
+ *
+ * - The original stack pointer (in a1) must not be modified. The fast
+ * exception handler should only use a2 as the stack pointer.
+ *
+ * - If the fast handler manipulates the stack pointer (in a2), it has to
+ * register a valid fixup handler and cannot use the default handlers.
+ *
+ * - The handler can use any other generic register from a3 to a15, but it
+ * must save the content of these registers to stack (PT_AREG3...PT_AREGx)
+ *
+ * - These registers must be saved before a double exception can occur.
+ *
+ * - If we ever implement handling signals while in double exceptions, the
+ * number of registers a fast handler has saved (excluding a0 and a1) must
+ * be written to PT_AREG1. (1 if only a3 is used, 2 for a3 and a4, etc. )
+ *
+ * The fixup handlers are special handlers:
+ *
+ * - Fixup entry conditions differ from regular exceptions:
+ *
+ * a0: DEPC
+ * a1: a1
+ * a2: trashed, original value in EXC_TABLE_DOUBLE_A2
+ * a3: exctable
+ * depc: a0
+ * excsave_1: a3
+ *
+ * - When the kernel enters the fixup handler, it still assumes it is in a
+ * critical section, so EXC_TABLE_FIXUP variable is set to exc_table.
+ * The fixup handler, therefore, has to re-register itself as the fixup
+ * handler before it returns from the double exception.
+ *
+ * - Fixup handler can share the same exception frame with the fast handler.
+ * The kernel stack pointer is not changed when entering the fixup handler.
+ *
+ * - Fixup handlers can jump to the default kernel and user exception
+ * handlers. Before it jumps, though, it has to setup a exception frame
+ * on stack. Because the default handler resets the register fixup handler
+ * the fixup handler must make sure that the default handler returns to
+ * it instead of the exception address, so it can re-register itself as
+ * the fixup handler.
+ *
+ * In case of a critical condition where the kernel cannot recover, we jump
+ * to unrecoverable_exception with the following entry conditions.
+ * All registers a0...a15 are unchanged from the last exception, except:
+ *
+ * a0: last address before we jumped to the unrecoverable_exception.
+ * excsave_1: a0
+ *
+ *
+ * See the handle_alloca_user and spill_registers routines for example clients.

+ * FIXME: Note: we currently don't allow signal handling coming from a double
+ * exception, so the item markt with (*) is not required.

+ * This function is intended to do the same thing as the standard

+ * However, where the source and/or destination references

+ * !!!!!!! XTFIXME:
+ * !!!!!!! Handling of IRAM/IROM has not yet
+ * !!!!!!! been implemented.
+ *
+ * The bcopy version is provided here to avoid the overhead
+ * of an extra call, for callers that require this convention.
+ *
+ * The (general case) algorithm is as follows:
+ * If destination is unaligned, align it by conditionally
+ * copying 1 and 2 bytes.
+ * If source is aligned,
+ * do 16 bytes with a loop, and then finish up with
+ * 8, 4, 2, and 1 byte copies conditional on the length;
+ * else (if source is unaligned),
+ * do the same, but use SRC to align the source data.
+ * This code tries to use fall-through branches for the common
+ * case of aligned source and destination and multiple
+ * of 4 (or 8) length.
+ *
+ * Register use:
+ * a0/ return address
+ * a1/ stack pointer

+ AES cipher algorithms (FIPS-197). AES uses the Rijndael
+ algorithm.
+
+ Rijndael appears to be consistently a very good performer in
+ both hardware and software across a wide range of computing
+ environments regardless of its use in feedback or non-feedback
+ modes. Its key setup time is excellent, and its key agility is
+ good. Rijndael's very low memory requirements make it very well
+ suited for restricted-space environments, in which it also
+ demonstrates excellent performance. Rijndael's operations are
+ among the easiest to defend against power and timing attacks.
+
+ The AES specifies three key sizes: 128, 192 and 256 bits
+
+ See <http://csrc.nist.gov/encryption/aes/> for more information.

+ A fifth-order polynomial fits the unofficial data (provided by Alex van
+ Kaam <darkside@chello.nl>) a bit better. It also give more reasonable
+ numbers on my machine (ie. they agree with what my BIOS tells me).
+ Here's the fifth-order fit to the 8-bit data:
+ temp = 1.625093e-10*val^5 - 1.001632e-07*val^4 + 2.457653e-05*val^3 -
+ 2.967619e-03*val^2 + 2.175144e-01*val - 7.090067e+0.
+
+ (2000-10-25- RFD: thanks to Uwe Andersen <uandersen@mayah.com> for
+ finding my typos in this formula!)
+
+ Alas, none of the elegant function-fit solutions will work because we
+ aren't allowed to use floating point in the kernel and doing it with
+ integers doesn't provide enough precision. So we'll do boring old
+ look-up table stuff. The unofficial data (see below) have effectively
+ 7-bit resolution (they are rounded to the nearest degree). I'm assuming
+ that the transfer function of the device is monotonic and smooth, so a
+ smooth function fit to the data will allow us to get better precision.
+ I used the 5th-order poly fit described above and solved for
+ VIA register values 0-255. I *10 before rounding, so we get tenth-degree
+ precision. (I could have done all 1024 values for our 10-bit readings,
+ but the function is very linear in the useful range (0-80 deg C), so
+ we'll just use linear interpolation for 10-bit readings.) So, tempLUT
+ is the temp at via register values 0-255: */

- A fifth-order polynomial fits the unofficial data (provided by Alex van

- Here's the fifth-order fit to the 8-bit data:
- temp = 1.625093e-10*val^5 - 1.001632e-07*val^4 + 2.457653e-05*val^3 -

- (2000-10-25- RFD: thanks to Uwe Andersen <uandersen@mayah.com> for
- finding my typos in this formula!)
-
- Alas, none of the elegant function-fit solutions will work because we
- aren't allowed to use floating point in the kernel and doing it with
- integers doesn't provide enough precision. So we'll do boring old
- look-up table stuff. The unofficial data (see below) have effectively
- 7-bit resolution (they are rounded to the nearest degree). I'm assuming
- that the transfer function of the device is monotonic and smooth, so a
- smooth function fit to the data will allow us to get better precision.
- I used the 5th-order poly fit described above and solved for
- VIA register values 0-255. I *10 before rounding, so we get tenth-degree
- precision. (I could have done all 1024 values for our 10-bit readings,
- but the function is very linear in the useful range (0-80 deg C), so
- we'll just use linear interpolation for 10-bit readings.) So, tempLUT
- is the temp at via register values 0-255: */

+ *
+ * May be copied or modified under the terms of the GNU General Public License
+ * Based in part on the ITE vendor provided SCSI driver.
+ *
+ * Documentation available from
+ * http://www.ite.com.tw/pc/IT8212F_V04.pdf
+ * Some other documents are NDA.
+ *
+ * The ITE8212 isn't exactly a standard IDE controller. It has two
+ * modes. In pass through mode then it is an IDE controller. In its smart
+ * mode its actually quite a capable hardware raid controller disguised
+ * as an IDE controller. Smart mode only understands DMA read/write and
+ * identify, none of the fancier commands apply. The IT8211 is identical
+ * in other respects but lacks the raid mode.
+ *
+ * Errata:
+ * o Rev 0x10 also requires master/slave hold the same DMA timings and
+ * cannot do ATAPI MWDMA.
+ * o The identify data for raid volumes lacks CHS info (technically ok)
+ * but also fails to set the LBA28 and other bits. We fix these in
+ * the IDE probe quirk code.
+ * o If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
+ * raid then the controller firmware dies
+ * o Smart mode without RAID doesn't clear all the necessary identify
+ * bits to reduce the command set to the one used
+ *
+ * This has a few impacts on the driver
+ * - In pass through mode we do all the work you would expect
+ * - In smart mode the clocking set up is done by the controller generally
+ * but we must watch the other limits and filter.
+ * - There are a few extra vendor commands that actually talk to the
+ * controller but only work PIO with no IRQ.
+ *
+ * Vendor areas of the identify block in smart mode are used for the
+ * timing and policy set up. Each HDD in raid mode also has a serial
+ * block on the disk. The hardware extra commands are get/set chip status,
+ * rebuild, get rebuild status.
+ *
+ * In Linux the driver supports pass through mode as if the device was
+ * just another IDE controller. If the smart mode is running then
+ * volumes are managed by the controller firmware and each IDE "disk"
+ * is a raid volume. Even more cute - the controller can do automated
+ * hotplug and rebuild.
+ *
+ * The pass through controller itself is a little demented. It has a
+ * flaw that it has a single set of PIO/MWDMA timings per channel so
+ * non UDMA devices restrict each others performance. It also has a
+ * single clock source per channel so mixed UDMA100/133 performance
+ * isn't perfect and we have to pick a clock. Thankfully none of this
+ * matters in smart mode. ATAPI DMA is not currently supported.
+ *
+ * It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
+ *
+ * TODO
+ * - ATAPI UDMA is ok but not MWDMA it seems
+ * - RAID configuration ioctls
+ * - Move to libata once it grows up

- hdlc_decode - decodes HDLC frames from a transparent bit stream.

- The source buffer is scanned for valid HDLC frames looking for
- flags (01111110) to indicate the start of a frame. If the start of
- the frame is found, the bit stuffing is removed (0 after 5 1's).
- When a new flag is found, the complete frame has been received
- and the CRC is checked.
- If a valid frame is found, the function returns the frame length
- excluding the CRC with the bit HDLC_END_OF_FRAME set.
- If the beginning of a valid frame is found, the function returns
- the length.
- If a framing error is found (too many 1s and not a flag) the function
- returns the length with the bit HDLC_FRAMING_ERROR set.
- If a CRC error is found the function returns the length with the
- bit HDLC_CRC_ERROR set.
- If the frame length exceeds the destination buffer size, the function
- returns the length with the bit HDLC_LENGTH_ERROR set.

- * at the input to the receiver becomes 'stuck' and locks up the receiver.
- * This problem can occur as a result of a zero bit at the receiver input
- * coincident with any of the following events:
- *
- * The SCC is initialized (hardware or software).
- * A framing error is detected.
- * The clocking option changes from synchronous or X1 asynchronous
- * clocking to X16, X32, or X64 asynchronous clocking.
- * The decoding mode is changed among NRZ, NRZI, FM0, or FM1.
- *
- * This workaround attempts to recover from the lockup condition by placing
- * the SCC in synchronous loopback mode with a fast clock before programming

- Ultima Electronic/Artec T1 USB TVBOX
- Compro Videomate DVB-U2000 - DVB-T USB

- Artec T1 USB1.1 and USB2.0 boxes
- Yakumo/Typhoon DVB-T USB2.0
- Hanftek UMT-010 USB2.0
- Hauppauge WinTV NOVA-T USB2
-
- The VP7041 seems to be identical to "CTS Portable" (Chinese
- Television System).
-
- These devices can be understood as budget ones, they "only" deliver
- (a part of) the MPEG2 transport stream.
-
- A firmware is needed to get the device working. See Documentation/dvb/README.dibusb
- details.
-

+/* DVB USB compliant linux driver for Conexant USB reference design.

+ * for analogue capturing it also has a cx22702 DVB-T demodulator on the main
+ * board. Besides it has a atiremote (X10) and a USB2.0 hub onboard.
+ *
+ * Maybe it is a little bit premature to call this driver cxusb, but I assume
+ * the USB protocol is identical or at least inherited from the reference
+ * design, so it can be reused for the "analogue-only" device (if it will
+ * appear at all).
+ *
+ * TODO: check if the cx25840-driver (from ivtv) can be used for the analogue
+ * part

+ This enables support for reading, writing and locking so called
+ "Protection Registers" present on some flash chips.
+ A subset of them are pre-programmed at the factory with a
+ unique set of values. The rest is user-programmable.
+
+ The user-programmable Protection Registers contain one-time
+ programmable (OTP) bits; when programmed, register bits cannot be
+ erased. Each Protection Register can be accessed multiple times to
+ program individual bits, as long as the register remains unlocked.
+
+ Each Protection Register has an associated Lock Register bit. When a
+ Lock Register bit is programmed, the associated Protection Register
+ can only be read; it can no longer be programmed. Additionally,
+ because the Lock Register bits themselves are OTP, when programmed,
+ Lock Register bits cannot be erased. Therefore, when a Protection
+ Register is locked, it cannot be unlocked.
+
+ This feature should therefore be used with extreme care. Any mistake
+ in the programming of OTP bits will waste them.

-The ELAN-104NC has up to 8 Mibyte of Intel StrataFlash (28F320/28F640) in x16
-mode. This drivers uses the CFI probe and Intel Extended Command Set drivers.
-
-The flash is accessed as follows:
-
- 32 kbyte memory window at 0xb0000-0xb7fff
-
- 16 bit I/O port (0x22) for some sort of paging.
-
-The single flash device is divided into 3 partition which appear as separate
-MTD devices.
-
-Linux thinks that the I/O port is used by the PIC and hence check_region() will
-always fail. So we don't do it. I just hope it doesn't break anything.

*
+ * 12-05-2004 dmarlin: add workaround for Renesas AG-AND chips "disturb" issue.
+ * Basically, any block not rewritten may lose data when surrounding blocks
+ * are rewritten many times. JFFS2 ensures this doesn't happen for blocks
+ * it uses, but the Bad Block Table(s) may not be rewritten. To ensure they
+ * do not lose data, force them to be rewritten when some of the surrounding
+ * blocks are erased. Rather than tracking a specific nearby block (which
+ * could itself go bad), use a page address 'mask' to select several blocks
+ * in the same area, and rewrite the BBT when any of them are erased.
+ *
+ * 01-03-2005 dmarlin: added support for the device recovery command sequence for Renesas
+ * AG-AND chips. If there was a sudden loss of power during an erase operation,
+ * a "device recovery" operation must be performed when power is restored
+ * to ensure correct operation.
+ *
+ * 01-20-2005 dmarlin: added support for optional hardware specific callback routine to
+ * perform extra error status checks on erase and write failures. This required
+ * adding a wrapper function for nand_read_ecc.
+ *
* Credits:
* David Woodhouse for adding multichip support

+ AppleTalk is the protocol that Apple computers can use to communicate
+ on a network. If your Linux box is connected to such a network and you
+ wish to connect to it, say Y. You will need to use the netatalk package
+ so that your Linux box can act as a print and file server for Macs as
+ well as access AppleTalk printers. Check out
+ <http://www.zettabyte.net/netatalk/> on the WWW for details.
+ EtherTalk is the name used for AppleTalk over Ethernet and the
+ cheaper and slower LocalTalk is AppleTalk over a proprietary Apple
+ network using serial links. EtherTalk and LocalTalk are fully
+ supported by Linux.
+
+ General information about how to connect Linux, Windows machines and
+ Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>. The
+ NET-3-HOWTO, available from
+ <http://www.tldp.org/docs.html#howto>, contains valuable
+ information as well.
+
+ To compile this driver as a module, choose M here: the module will be
+ called appletalk. You almost certainly want to compile it as a
+ module so you can restart your AppleTalk stack without rebooting
+ your machine. I hear that the GNU boycott of Apple is over, so
+ even politically correct people are allowed to say Y here.

- * It works on D-Link *only* after a tcpdump. Weird...
- * And still doesn't work on Intel card. Grrrr...
- * o Update the mode after a setport3
- * o Add preamble setting for Symbol cards (not yet enabled)
- * o Don't complain as much about Symbol cards...
- *
- * v0.04 -> v0.04b - 22/4/2001 - David Gibson
- * o Removed the 'eth' parameter - always use ethXX as the
- * interface name instead of dldwdXX. The other was racy
- * anyway.

- * o D-Link firmware doesn't support multicast. We just print a few
- * error messages, but otherwise everything works...
- * o For David : set/getport3 works fine, just upgrade iwpriv...
- *
- * v0.05b -> v0.05c - 5/5/2001 - Benjamin Herrenschmidt

- *
- * v0.05d -> v0.06 - 25/5/2001 - Jean II
- * Original patch from "Hong Lin" <alin AT redhat.com>,
- * "Ian Kinner" <ikinner AT redhat.com>
- * and "David Smith" <dsmith AT redhat.com>
- * o Init of priv->tx_rate_ctrl in firmware specific section.
- * o Prism2/Symbol rate, upto should be 0xF and not 0x15. Doh !
- * o Spectrum card always need cor_reset (for every reset)
- * o Fix cor_reset to not lose bit 7 in the register
- * o flush_stale_links to remove zombie Pcmcia instances
- * o Ack previous hermes event before reset
- * Me (with my little hands)
- * o Allow orinoco.c to call cor_reset via priv->card_reset_handler
- * o Add priv->need_card_reset to toggle this feature
- * o Fix various buglets when setting WEP in Symbol firmware
- * Now, encryption is fully functional on Symbol cards. Youpi !
- *
- * v0.06 -> v0.06b - 25/5/2001 - Jean II
- * o IBSS on Symbol use port_mode = 4. Please don't ask...
- *
- * v0.06b -> v0.06c - 29/5/2001 - Jean II
- * o Show first spy address in /proc/net/wireless for IBSS mode as well
- *
- * v0.06c -> v0.06d - 6/7/2001 - David Gibson

- * wishes to reduce the number of unnecessary messages.
- * o Removed bogus message on CRC error.
- * o Merged fixes for v0.08 Prism 2 firmware from William Waghorn
- * <willwaghorn AT yahoo.co.uk>
- * o Slight cleanup/re-arrangement of firmware detection code.
- *
- * v0.06d -> v0.06e - 1/8/2001 - David Gibson
- * o Removed some redundant global initializers (orinoco_cs.c).
- * o Added some module metadata
- *
- * v0.06e -> v0.06f - 14/8/2001 - David Gibson
- * o Wording fix to license
- * o Added a 'use_alternate_encaps' module parameter for APs which need an
- * oui of 00:00:00. We really need a better way of handling this, but
- * the module flag is better than nothing for now.
- *
- * v0.06f -> v0.07 - 20/8/2001 - David Gibson
- * o Removed BAP error retries from hermes_bap_seek(). For Tx we now
- * let the upper layers handle the retry, we retry explicitly in the
- * Rx path, but don't make as much noise about it.
- * o Firmware detection cleanups.
- *
- * v0.07 -> v0.07a - 1/10/3001 - Jean II
- * o Add code to read Symbol firmware revision, inspired by latest code
- * in Spectrum24 by Lee John Keyser-Allen - Thanks Lee !
- * o Thanks to Jared Valentine <hidden AT xmission.com> for "providing" me
- * a 3Com card with a recent firmware, fill out Symbol firmware
- * capabilities of latest rev (2.20), as well as older Symbol cards.
- * o Disable Power Management in newer Symbol firmware, the API
- * has changed (documentation needed).
- *
- * v0.07a -> v0.08 - 3/10/2001 - David Gibson
- * o Fixed a possible buffer overrun found by the Stanford checker (in
- * dldwd_ioctl_setiwencode()). Can only be called by root anyway, so not
- * a big problem.
- * o Turned has_big_wep on for Intersil cards. That's not true for all of
- * them but we should at least let the capable ones try.
- * o Wait for BUSY to clear at the beginning of hermes_bap_seek(). I
- * realized that my assumption that the driver's serialization
- * would prevent the BAP being busy on entry was possibly false, because
- * things other than seeks may make the BAP busy.
- * o Use "alternate" (oui 00:00:00) encapsulation by default.
- * Setting use_old_encaps will mimic the old behaviour, but I think we
- * will be able to eliminate this.
- * o Don't try to make __initdata const (the version string). This can't
- * work because of the way the __initdata sectioning works.
- * o Added MODULE_LICENSE tags.
- * o Support for PLX (transparent PCMCIA->PCI bridge) cards.
- * o Changed to using the new type-fascist min/max.
- *
- * v0.08 -> v0.08a - 9/10/2001 - David Gibson
- * o Inserted some missing acknowledgements/info into the Changelog.
- * o Fixed some bugs in the normalization of signal level reporting.
- * o Fixed bad bug in WEP key handling on Intersil and Symbol firmware,
- * which led to an instant crash on big-endian machines.
- *
- * v0.08a -> v0.08b - 20/11/2001 - David Gibson
- * o Lots of cleanup and bugfixes in orinoco_plx.c
- * o Cleanup to handling of Tx rate setting.
- * o Removed support for old encapsulation method.
- * o Removed old "dldwd" names.
- * o Split RID constants into a new file hermes_rid.h
- * o Renamed RID constants to match linux-wlan-ng and prism2.o
- * o Bugfixes in hermes.c
- * o Poke the PLX's INTCSR register, so it actually starts
- * generating interrupts. These cards might actually work now.
- * o Update to wireless extensions v12 (Jean II)
- * o Support for tallies and inquire command (Jean II)
- * o Airport updates for newer PPC kernels (BenH)
- *
- * v0.08b -> v0.09 - 21/12/2001 - David Gibson
- * o Some new PCI IDs for PLX cards.
- * o Removed broken attempt to do ALLMULTI reception. Just use
- * promiscuous mode instead
- * o Preliminary work for list-AP (Jean II)
- * o Airport updates from (BenH)
- * o Eliminated racy hw_ready stuff
- * o Fixed generation of fake events in irq handler. This should
- * finally kill the EIO problems (Jean II & dgibson)
- * o Fixed breakage of bitrate set/get on Agere firmware (Jean II)
- *
- * v0.09 -> v0.09a - 2/1/2002 - David Gibson
- * o Fixed stupid mistake in multicast list handling, triggering
- * a BUG()
- *
- * v0.09a -> v0.09b - 16/1/2002 - David Gibson
- * o Fixed even stupider mistake in new interrupt handling, which
- * seriously broke things on big-endian machines.
- * o Removed a bunch of redundant includes and exports.
- * o Removed a redundant MOD_{INC,DEC}_USE_COUNT pair in airport.c
- * o Don't attempt to do hardware level multicast reception on
- * Intersil firmware, just go promisc instead.
- * o Typo fixed in hermes_issue_cmd()
- * o Eliminated WIRELESS_SPY #ifdefs
- * o Status code reported on Tx exceptions
- * o Moved netif_wake_queue() from ALLOC interrupts to TX and TXEXC
- * interrupts, which should fix the timeouts we're seeing.
- *
- * v0.09b -> v0.10 - 25 Feb 2002 - David Gibson
- * o Removed nested structures used for header parsing, so the
- * driver should now work without hackery on ARM
- * o Fix for WEP handling on Intersil (Hawk Newton)
- * o Eliminated the /proc/hermes/ethXX/regs debugging file. It
- * was never very useful.
- * o Make Rx errors less noisy.
- *
- * v0.10 -> v0.11 - 5 Apr 2002 - David Gibson
- * o Laid the groundwork in hermes.[ch] for devices which map
- * into PCI memory space rather than IO space.
- * o Fixed bug in multicast handling (cleared multicast list when
- * leaving promiscuous mode).
- * o Relegated Tx error messages to debug.
- * o Cleaned up / corrected handling of allocation lengths.
- * o Set OWNSSID in IBSS mode for WinXP interoperability (jimc).
- * o Change to using alloc_etherdev() for structure allocations.
- * o Check for and drop undersized packets.
- * o Fixed a race in stopping/waking the queue. This should fix
- * the timeout problems (Pavel Roskin)
- * o Reverted to netif_wake_queue() on the ALLOC event.
- * o Fixes for recent Symbol firmwares which lack AP density
- * (Pavel Roskin).
- *
- * v0.11 -> v0.11a - 29 Apr 2002 - David Gibson
- * o Handle different register spacing, necessary for Prism 2.5
- * PCI adaptors (Steve Hill).
- * o Cleaned up initialization of card structures in orinoco_cs
- * and airport. Removed card->priv field.
- * o Make response structure optional for hermes_docmd_wait()
- * Pavel Roskin)
- * o Added PCI id for Nortel emobility to orinoco_plx.c.
- * o Cleanup to handling of Symbol's allocation bug. (Pavel Roskin)
- * o Cleanups to firmware capability detection.
- * o Arrange for orinoco_pci.c to override firmware detection.
- * We should be able to support the PCI Intersil cards now.
- * o Cleanup handling of reset_cor and hard_reset (Pavel Roskin).
- * o Remove erroneous use of USER_BAP in the TxExc handler (Jouni
- * Malinen).
- * o Makefile changes for better integration into David Hinds
- * pcmcia-cs package.
- *
- * v0.11a -> v0.11b - 1 May 2002 - David Gibson
- * o Better error reporting in orinoco_plx_init_one()
- * o Fixed multiple bad kfree() bugs introduced by the
- * alloc_orinocodev() changes.
- *
- * v0.11b -> v0.12 - 19 Jun 2002 - David Gibson
- * o Support changing the MAC address.
- * o Correct display of Intersil firmware revision numbers.
- * o Entirely revised locking scheme. Should be both simpler and
- * better.
- * o Merged some common code in orinoco_plx, orinoco_pci and
- * airport by creating orinoco_default_{open,stop,reset}()
- * which are used as the dev->open, dev->stop, priv->reset
- * callbacks if none are specified when alloc_orinocodev() is
- * called.
- * o Removed orinoco_plx_interrupt() and orinoco_pci_interrupt().
- * They didn't do anything.
- *
- * v0.12 -> v0.12a - 4 Jul 2002 - David Gibson
- * o Some rearrangement of code.
- * o Numerous fixups to locking and rest handling, particularly
- * for PCMCIA.
- * o This allows open and stop net_device methods to be in
- * orinoco.c now, rather than in the init modules.
- * o In orinoco_cs.c link->priv now points to the struct
- * net_device not to the struct orinoco_private.
- * o Added a check for undersized SNAP frames, which could cause
- * crashes.
- *
- * v0.12a -> v0.12b - 11 Jul 2002 - David Gibson
- * o Fix hw->num_init testing code, so num_init is actually
- * incremented.
- * o Fix very stupid bug in orinoco_cs which broke compile with
- * CONFIG_SMP.
- * o Squashed a warning.
- *
- * v0.12b -> v0.12c - 26 Jul 2002 - David Gibson
- * o Change to C9X style designated initializers.
- * o Add support for 3Com AirConnect PCI.
- * o No longer ignore the hard_reset argument to
- * alloc_orinocodev(). Oops.
- *
- * v0.12c -> v0.13beta1 - 13 Sep 2002 - David Gibson
- * o Revert the broken 0.12* locking scheme and go to a new yet
- * simpler scheme.
- * o Do firmware resets only in orinoco_init() and when waking
- * the card from hard sleep.
- *
- * v0.13beta1 -> v0.13 - 27 Sep 2002 - David Gibson
- * o Re-introduced full resets (via schedule_task()) on Tx
- * timeout.
- *
- * v0.13 -> v0.13a - 30 Sep 2002 - David Gibson
- * o Minor cleanups to info frame handling. Add basic support
- * for linkstatus info frames.
- * o Include required kernel headers in orinoco.h, to avoid
- * compile problems.
- *
- * v0.13a -> v0.13b - 10 Feb 2003 - David Gibson
- * o Implemented hard reset for Airport cards
- * o Experimental suspend/resume implementation for orinoco_pci
- * o Abolished /proc debugging support, replaced with a debugging
- * iwpriv. Now it's ugly and simple instead of ugly and complex.
- * o Bugfix in hermes.c if the firmware returned a record length
- * of 0, we could go clobbering memory.
- * o Bugfix in orinoco_stop() - it used to fail if hw_unavailable
- * was set, which was usually true on PCMCIA hot removes.
- * o Track LINKSTATUS messages, silently drop Tx packets before
- * we are connected (avoids confusing the firmware), and only
- * give LINKSTATUS printk()s if the status has changed.
- *
- * v0.13b -> v0.13c - 11 Mar 2003 - David Gibson
- * o Cleanup: use dev instead of priv in various places.
- * o Bug fix: Don't ReleaseConfiguration on RESET_PHYSICAL event
- * if we're in the middle of a (driver initiated) hard reset.
- * o Bug fix: ETH_ZLEN is supposed to include the header
- * (Dionysus Blazakis & Manish Karir)
- * o Convert to using workqueues instead of taskqueues (and
- * backwards compatibility macros for pre 2.5.41 kernels).
- * o Drop redundant (I think...) MOD_{INC,DEC}_USE_COUNT in
- * airport.c
- * o New orinoco_tmd.c init module from Joerg Dorchain for
- * TMD7160 based PCI to PCMCIA bridges (similar to
- * orinoco_plx.c).
- *
- * v0.13c -> v0.13d - 22 Apr 2003 - David Gibson
- * o Make hw_unavailable a counter, rather than just a flag, this
- * is necessary to avoid some races (such as a card being
- * removed in the middle of orinoco_reset().
- * o Restore Release/RequestConfiguration in the PCMCIA event handler
- * when dealing with a driver initiated hard reset. This is
- * necessary to prevent hangs due to a spurious interrupt while
- * the reset is in progress.
- * o Clear the 802.11 header when transmitting, even though we
- * don't use it. This fixes a long standing bug on some
- * firmwares, which seem to get confused if that isn't done.
- * o Be less eager to de-encapsulate SNAP frames, only do so if
- * the OUI is 00:00:00 or 00:00:f8, leave others alone. The old
- * behaviour broke CDP (Cisco Discovery Protocol).
- * o Use dev instead of priv for free_irq() as well as
- * request_irq() (oops).
- * o Attempt to reset rather than giving up if we get too many
- * IRQs.
- * o Changed semantics of __orinoco_down() so it can be called
- * safely with hw_unavailable set. It also now clears the
- * linkstatus (since we're going to have to reassociate).
- *
- * v0.13d -> v0.13e - 12 May 2003 - David Gibson
- * o Support for post-2.5.68 return values from irq handler.
- * o Fixed bug where underlength packets would be double counted
- * in the rx_dropped statistics.
- * o Provided a module parameter to suppress linkstatus messages.
- *
- * v0.13e -> v0.14alpha1 - 30 Sep 2003 - David Gibson
- * o Replaced priv->connected logic with netif_carrier_on/off()
- * calls.
- * o Remove has_ibss_any and never set the CREATEIBSS RID when
- * the ESSID is empty. Too many firmwares break if we do.
- * o 2.6 merges: Replace pdev->slot_name with pci_name(), remove
- * __devinitdata from PCI ID tables, use free_netdev().
- * o Enabled shared-key authentication for Agere firmware (from
- * Robert J. Moore <Robert.J.Moore AT allanbank.com>
- * o Move netif_wake_queue() (back) to the Tx completion from the
- * ALLOC event. This seems to prevent/mitigate the rolling
- * error -110 problems at least on some Intersil firmwares.
- * Theoretically reduces performance, but I can't measure it.
- * Patch from Andrew Tridgell <tridge AT samba.org>
- *
- * v0.14alpha1 -> v0.14alpha2 - 20 Oct 2003 - David Gibson
- * o Correctly turn off shared-key authentication when requested
- * (bugfix from Robert J. Moore).
- * o Correct airport sleep interfaces for current 2.6 kernels.
- * o Add code for key change without disabling/enabling the MAC
- * port. This is supposed to allow 802.1x to work sanely, but
- * doesn't seem to yet.
- *
* TODO
- * o New wireless extensions API (patch from Moustafa
- * Youssef, updated by Jim Carter and Pavel Roskin).
* o Handle de-encapsulation within network layer, provide 802.11
* headers (patch from Thomas 'Dent' Mirlacher)
- * o RF monitor mode support
* o Fix possible races in SPY handling.
* o Disconnect wireless extensions from fundamental configuration.
* o (maybe) Software WEP support (patch from Stano Meduna).

- bind_request() and bind_device() are merged by now. Register_client()
- is called right at the end of bind_request(), during the driver's
- ->attach() call. Individual descriptions:
-
- bind_request() connects a socket to a particular client driver.
- It looks up the specified device ID in the list of registered
- drivers, binds it to the socket, and tries to create an instance
- of the device. unbind_request() deletes a driver instance.
-
- Bind_device() associates a device driver with a particular socket.
- It is normally called by Driver Services after it has identified
- a newly inserted card. An instance of that driver will then be
- eligible to register as a client of this socket.
-
- Register_client() uses the dev_info_t handle to match the
- caller with a socket. The driver must have already been bound
- to a socket with bind_device() -- in fact, bind_device()
- allocates the client structure that will be used.

+ bind_request() and bind_device() are merged by now. Register_client()
+ is called right at the end of bind_request(), during the driver's
+ ->attach() call. Individual descriptions:
+
+ bind_request() connects a socket to a particular client driver.
+ It looks up the specified device ID in the list of registered
+ drivers, binds it to the socket, and tries to create an instance
+ of the device. unbind_request() deletes a driver instance.
+
+ Bind_device() associates a device driver with a particular socket.
+ It is normally called by Driver Services after it has identified
+ a newly inserted card. An instance of that driver will then be
+ eligible to register as a client of this socket.
+
+ Register_client() uses the dev_info_t handle to match the
+ caller with a socket. The driver must have already been bound
+ to a socket with bind_device() -- in fact, bind_device()
+ allocates the client structure that will be used.

- *
- * 1.5A: - Version for inclusion in 2.5 series kernel
- * - Modifications by Richard Purdie (rpurdie@rpsys.net)
- * - made compatible with kernel 2.5.6 onwards by changing
- * udsl_usb_send_data_context->urb to a pointer and adding code
- * to alloc and free it
- * - remove_wait_queue() added to udsl_atm_processqueue_thread()
- *
- * 1.5: - fixed memory leak when atmsar_decode_aal5 returned NULL.
- * (reported by stephen.robinson@zen.co.uk)
- *
- * 1.4: - changed the spin_lock() under interrupt to spin_lock_irqsave()
- * - unlink all active send urbs of a vcc that is being closed.
- *
- * 1.3.1: - added the version number
- *
- * 1.3: - Added multiple send urb support
- * - fixed memory leak and vcc->tx_inuse starvation bug

+ *
+ * 1.6: - No longer opens a connection if the firmware is not loaded
+ * - Added support for the speedtouch 330
+ * - Removed the limit on the number of devices
+ * - Module now autoloads on device plugin
+ * - Merged relevant parts of sarlib
+ * - Replaced the kernel thread with a tasklet

+ *
+ * 1.5A: - Version for inclusion in 2.5 series kernel
+ * - Modifications by Richard Purdie (rpurdie@rpsys.net)
+ * - made compatible with kernel 2.5.6 onwards by changing
+ * usbatm_usb_send_data_context->urb to a pointer and adding code
+ * to alloc and free it
+ * - remove_wait_queue() added to usbatm_atm_processqueue_thread()
+ *
+ * 1.5: - fixed memory leak when atmsar_decode_aal5 returned NULL.
+ * (reported by stephen.robinson@zen.co.uk)
+ *
+ * 1.4: - changed the spin_lock() under interrupt to spin_lock_irqsave()
+ * - unlink all active send urbs of a vcc that is being closed.
+ *
+ * 1.3.1: - added the version number
+ *
+ * 1.3: - Added multiple send urb support
+ * - fixed memory leak and vcc->tx_inuse starvation bug
+ * when not enough memory left in vcc.
+ *
+ * 1.2: - Fixed race condition in usbatm_usb_send_data()
+ * 1.1: - Turned off packet debugging

+ option if your board has this chip. If unsure, say N.
+
+ This driver does not support isochronous transfers.
+
+ To compile this driver as a module, choose M here: the
+ module will be called isp116x-hcd.

+ *
+ * This driver uses a ring buffer for time critical reading of
+ * interrupt in reports and provides read and write methods for
+ * raw interrupt reports (similar to the Windows HID driver).
+ * Devices based on the book USB COMPLETE by Jan Axelson may need
+ * such a compatibility to the Windows HID driver.

* Called when leasetime is changed.
*
- * if nfsd is not started, simply set the global lease.
- *
- * if nfsd(s) are running, lease change requires nfsv4 state to be reset.
- * e.g: boot_time is reset, existing nfs4_client structs are
- * used to fill reclaim_str_hashtbl, then all state (except for the
- * reclaim_str_hashtbl) is re-initialized.
- *
- * if the old lease time is greater than the new lease time, the grace
- * period needs to be set to the old lease time to allow clients to reclaim
- * their state. XXX - we may want to set the grace period == lease time
- * after an initial grace period == old lease time
- *
- * if an error occurs in this process, the new lease is set, but the server
- * will not honor OPEN or LOCK reclaims, and will return nfserr_no_grace
- * which means OPEN/LOCK/READ/WRITE will fail during grace period.
- *
- * clients will attempt to reset all state with SETCLIENTID/CONFIRM, and
- * OPEN and LOCK reclaims.
+ * The only way the protocol gives us to handle on-the-fly lease changes is to
+ * simulate a reboot. Instead of doing that, we just wait till the next time
+ * we start to register any changes in lease time. If the administrator
+ * really wants to change the lease time *now*, they can go ahead and bring

+ * PIC AS DEVICE ZERO
+ * ------------------
+ *
+ * PIC handles PCI/X busses. PCI/X requires that the 'bridge' (i.e. PIC)
+ * be designated as 'device 0'. That is a departure from earlier SGI
+ * PCI bridges. Because of that we use config space 1 to access the
+ * config space of the first actual PCI device on the bus.
+ * Here's what the PIC manual says:
+ *
+ * The current PCI-X bus specification now defines that the parent
+ * hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
+ * reduced the total number of devices from 8 to 4 and removed the
+ * device registers and windows, now only supporting devices 0,1,2, and
+ * 3. PIC did leave all 8 configuration space windows. The reason was
+ * there was nothing to gain by removing them. Here in lies the problem.
+ * The device numbering we do using 0 through 3 is unrelated to the device
+ * numbering which PCI-X requires in configuration space. In the past we
+ * correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
+ * PCI-X requires we start a 1, not 0 and currently the PX brick
+ * does associate our:
+ *
+ * device 0 with configuration space window 1,
+ * device 1 with configuration space window 2,
+ * device 2 with configuration space window 3,
+ * device 3 with configuration space window 4.
+ *
+ * The net effect is that all config space access are off-by-one with
+ * relation to other per-slot accesses on the PIC.
+ * Here is a table that shows some of that:
+ *
+ * Internal Slot#
+ * |
+ * | 0 1 2 3

+ * Encode and decode a swap entry.
+ * Each PTE in a process VM's page table is either:
+ * "present" -- valid and not swapped out, protection bits are meaningful;
+ * "not present" -- which further subdivides in these two cases:
+ * "none" -- no mapping at all; identified by pte_none(), set by pte_clear(
+ * "swapped out" -- the page is swapped out, and the SWP macros below
+ * are used to store swap file info in the PTE itself.
+ *
+ * In the Xtensa processor MMU, any PTE entries in user space (or anywhere
+ * in virtual memory that can map differently across address spaces)
+ * must have a correct ring value that represents the RASID field that
+ * is changed when switching address spaces. Eg. such PTE entries cannot
+ * be set to ring zero, because that can cause a (global) kernel ASID
+ * entry to be created in the TLBs (even with invalid cache attribute),
+ * potentially causing a multihit exception when going back to another
+ * address space that mapped the same virtual address at another ring.
+ *
+ * SO: we avoid using ring bits (_PAGE_RING_MASK) in "not present" PTEs.
+ * We also avoid using the _PAGE_VALID bit which must be zero for non-present
+ * pages.
+ *
+ * We end up with the following available bits: 1..3 and 7..31.
+ * We don't bother with 1..3 for now (we can use them later if needed),
+ * and chose to allocate 6 bits for SWP_TYPE and the remaining 19 bits
+ * for SWP_OFFSET. At least 5 bits are needed for SWP_TYPE, because it
+ * is currently implemented as an index into swap_info[MAX_SWAPFILES]
+ * and MAX_SWAPFILES is currently defined as 32 in <linux/swap.h>.
+ * However, for some reason all other architectures in the 2.4 kernel
+ * reserve either 6, 7, or 8 bits so I'll not detract from that for now. :)
+ * SWP_OFFSET is an offset into the swap file in page-size units, so
+ * with 4 kB pages, 19 bits supports a maximum swap file size of 2 GB.
+ *
+ * FIXME: 2 GB isn't very big. Other bits can be used to allow
+ * larger swap sizes. In the meantime, it appears relatively easy to get
+ * around the 2 GB limitation by simply using multiple swap files.

+ * instruction. It satisfies the Xtensa ABI while minizing argument
+ * shifting.
+ *
+ * The Xtensa ABI and software conventions require the system-call
+ * number in a2. If an argument exists in a2, we move it to the next
+ * available register. Note that for improved efficiency, we do NOT
+ * shift all parameters down one register to maintain the original
+ * order.
+ *
+ * At best case (zero arguments), we just write the syscall number to
+ * a2. At worst case (1 to 6 arguments), we move the argument in a2
+ * to the next available register, then write the syscall number to
+ * a2.

+ * General notes on MMU parameters.
+ *
+ * Terminology:
+ * ASID = address-space ID (acts as an "extension" of virtual addresses)
+ * VPN = virtual page number
+ * PPN = physical page number
+ * CA = encoded cache attribute (access modes)
+ * TLB = translation look-aside buffer (term is stretched somewhat here)
+ * I = instruction (fetch accesses)
+ * D = data (load and store accesses)
+ * way = each TLB (ITLB and DTLB) consists of a number of "ways"
+ * that simultaneously match the virtual address of an access;
+ * a TLB successfully translates a virtual address if exactly
+ * one way matches the vaddr; if none match, it is a miss;
+ * if multiple match, one gets a "multihit" exception;
+ * each way can be independently configured in terms of number of
+ * entries, page sizes, which fields are writable or constant, etc.
+ * set = group of contiguous ways with exactly identical parameters
+ * ARF = auto-refill; hardware services a 1st-level miss by loading a PTE
+ * from the page table and storing it in one of the auto-refill ways;
+ * if this PTE load also misses, a miss exception is posted for s/w.
+ * min-wired = a "min-wired" way can be used to map a single (minimum-sized)
+ * page arbitrarily under program control; it has a single entry,
+ * is non-auto-refill (some other way(s) must be auto-refill),
+ * all its fields (VPN, PPN, ASID, CA) are all writable, and it
+ * supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current
+ * restriction is that this be the only page size it supports).
+ *
+ * TLB way entries are virtually indexed.
+ * TLB ways that support multiple page sizes:
+ * - must have all writable VPN and PPN fields;
+ * - can only use one page size at any given time (eg. setup at startup),
+ * selected by the respective ITLBCFG or DTLBCFG special register,
+ * whose bits n*4+3 .. n*4 index the list of page sizes for way n
+ * (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n);
+ * this list may be sparse for auto-refill ways because auto-refill
+ * ways have independent lists of supported page sizes sharing a
+ * common encoding with PTE entries; the encoding is the index into
+ * this list; unsupported sizes for a given way are zero in the list;
+ * selecting unsupported sizes results in undefined hardware behaviour;
+ * - is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition).

+ * floop, floopnez, floopgtz, floopend
+ *
+ * These macros are used for fast inner loops that

+ * the zero-overhead LOOP instructions; otherwise
+ * they use explicit decrement and branch instructions.
+ *
+ * They are used in pairs, with floop, floopnez or floopgtz
+ * at the beginning of the loop, and floopend at the end.
+ *
+ * Each pair of loop macro calls must be given the loop count
+ * address register and a unique label for that loop.
+ *
+ * Example:
+ *
+ * movi a3, 16 // loop 16 times
+ * floop a3, myloop1
+ * :
+ * bnez a7, end1 // exit loop if a7 != 0
+ * :

+ * end1:
+ *
+ * Like the LOOP instructions, these macros cannot be
+ * nested, must include at least one instruction,
+ * cannot call functions inside the loop, etc.
+ * The loop can be exited by jumping to the instruction
+ * following floopend (or elsewhere outside the loop),
+ * or continued by jumping to a NOP instruction placed
+ * immediately before floopend.
+ *
+ * Unlike LOOP instructions, the register passed to floop*
+ * cannot be used inside the loop, because it is used as
+ * the loop counter if the Loops option is not configured.
+ * And its value is undefined after exiting the loop.
+ * And because the loop counter register is active inside
+ * the loop, you can't easily use this construct to loop
+ * across a register file using ROTW as you might with LOOP
+ * instructions, unless you copy the loop register along.

+ * the context of a simulation (as opposed to a Unix kernel).
+ *
+ * These services behave largely as if they had been invoked
+ * as a task in the simulator host's operating system
+ * (eg. files accessed are those of the simulator host).
+ * However, these SIMCALLs model a virtual operating system
+ * so that various definitions, bit assignments etc
+ * (eg. open mode bits, errno values, etc) are independent
+ * of the host operating system used to run the simulation.
+ * Rather these definitions are specific to the Xtensa ISS.
+ * This way Xtensa ISA code written to use these SIMCALLs
+ * can (in principle) be simulated on any host.
+ *
+ * Up to 6 parameters are passed in registers a3 to a8
+ * (note the 6th parameter isn't passed on the stack,
+ * unlike windowed function calling conventions).
+ * The return value is in a2. A negative value in the
+ * range -4096 to -1 indicates a negated error code to be
+ * reported in errno with a return value of -1, otherwise
+ * the value in a2 is returned as is.

+ * Device addresses.

+ * Note: for endianness-independence, use 32-bit loads and stores for all
+ * register accesses to Ethernet, DUART and LED devices. Undefined bits
+ * may need to be masked out if needed when reading if the actual register
+ * size is smaller than 32 bits.
+ *
+ * Note: XT2000 bus byte lanes are defined in terms of msbyte and lsbyte
+ * relative to the processor. So 32-bit registers are accessed consistently
+ * from both big and little endian processors. However, this means byte
+ * sequences are not consistent between big and little endian processors.
+ * This is fine for RAM, and for ROM if ROM is created for a specific
+ * processor (and thus has correct byte sequences). However this may be
+ * unexpected for Flash, which might contain a file-system that one wants
+ * to use for multiple processor configurations (eg. the Flash might contain
+ * the Ethernet card's address, endianness-independent application data, etc).
+ * That is, byte sequences written in Flash by a core of a given endianness
+ * will be byte-swapped when seen by a core of the other endianness.
+ * Someone implementing an endianness-independent Flash file system will
+ * likely handle this byte-swapping issue in the Flash driver software.

+
+ This allows reaction to interactive events by allowing a

+ *
+ * In that environment kexec copies the new kernel to its final
+ * resting place. This means I can only support memory whose

+ * addresses where (pfn << PAGE_SHIFT) > ULONG_MAX cannot be handled.
+ * If the assembly stub has more restrictive requirements
+ * KEXEC_SOURCE_MEMORY_LIMIT and KEXEC_DEST_MEMORY_LIMIT can be
+ * defined more restrictively in <asm/kexec.h>.
+ *
+ * The code for the transition from the current kernel to the
+ * the new kernel is placed in the control_code_buffer, whose size
+ * is given by KEXEC_CONTROL_CODE_SIZE. In the best case only a single
+ * page of memory is necessary, but some architectures require more.
+ * Because this memory must be identity mapped in the transition from
+ * virtual to physical addresses it must live in the range
+ * 0 - TASK_SIZE, as only the user space mappings are arbitrarily
+ * modifiable.
+ *
+ * The assembly stub in the control code buffer is passed a linked list
+ * of descriptor pages detailing the source pages of the new kernel,
+ * and the destination addresses of those source pages. As this data
+ * structure is not used in the context of the current OS, it must
+ * be self-contained.
+ *
+ * The code has been made to work with highmem pages and will use a
+ * destination page in its final resting place (if it happens
+ * to allocate it). The end product of this is that most of the
+ * physical address space, and most of RAM can be used.
+ *

+ * mapped, to simplify machine_kexec and make kexec_on_panic more

+ * ==========================================================================
+ *
+ * INTRODUCTION
+ *
+ * The textsearch infrastructure provides text searching facitilies for
+ * both linear and non-linear data. Individual search algorithms are
+ * implemented in modules and chosen by the user.
+ *
+ * ARCHITECTURE
+ *
+ * User
+ * +----------------+
+ * | finish()|<--------------(6)-----------------+
+ * |get_next_block()|<--------------(5)---------------+ |
+ * | | Algorithm | |
+ * | | +------------------------------+
+ * | | | init() find() destroy() |
+ * | | +------------------------------+
+ * | | Core API ^ ^ ^
+ * | | +---------------+ (2) (4) (8)
+ * | (1)|----->| prepare() |---+ | |
+ * | (3)|----->| find()/next() |-----------+ |
+ * | (7)|----->| destroy() |----------------------+
+ * +----------------+ +---------------+
+ *
+ * (1) User configures a search by calling _prepare() specifying the
+ * search parameters such as the pattern and algorithm name.
+ * (2) Core requests the algorithm to allocate and initialize a search
+ * configuration according to the specified parameters.
+ * (3) User starts the search(es) by calling _find() or _next() to
+ * fetch subsequent occurrences. A state variable is provided
+ * to the algorihtm to store persistant variables.
+ * (4) Core eventually resets the search offset and forwards the find()
+ * request to the algorithm.
+ * (5) Algorithm calls get_next_block() provided by the user continously
+ * to fetch the data to be searched in block by block.
+ * (6) Algorithm invokes finish() after the last call to get_next_block
+ * to clean up any leftovers from get_next_block. (Optional)
+ * (7) User destroys the configuration by calling _destroy().
+ * (8) Core notifies the algorithm to destroy algorithm specific
+ * allocations. (Optional)
+ *
+ * USAGE
+ *
+ * Before a search can be performed, a configuration must be created
+ * by calling textsearch_prepare() specyfing the searching algorithm and
+ * the pattern to look for. The returned configuration may then be used
+ * for an arbitary amount of times and even in parallel as long as a
+ * separate struct ts_state variable is provided to every instance.
+ *
+ * The actual search is performed by either calling textsearch_find_-
+ * continuous() for linear data or by providing an own get_next_block()
+ * implementation and calling textsearch_find(). Both functions return
+ * the position of the first occurrence of the patern or UINT_MAX if
+ * no match was found. Subsequent occurences can be found by calling
+ * textsearch_next() regardless of the linearity of the data.
+ *
+ * Once you're done using a configuration it must be given back via
+ * textsearch_destroy.
+ *
+ * EXAMPLE
+ *
+ * int pos;
+ * struct ts_config *conf;
+ * struct ts_state state;
+ * const char *pattern = "chicken";
+ * const char *example = "We dance the funky chicken";
+ *
+ * conf = textsearch_prepare("kmp", pattern, strlen(pattern),
+ * GFP_KERNEL, TS_AUTOLOAD);
+ * if (IS_ERR(conf)) {
+ * err = PTR_ERR(conf);
+ * goto errout;
+ * }
+ *
+ * pos = textsearch_find_continuous(conf, &state, example, strlen(example));
+ * if (pos != UINT_MAX)
+ * panic("Oh my god, dancing chickens at %d\n", pos);
+ *
+ * textsearch_destroy(conf);
+ *

+ *
+ * Implements a linear-time string-matching algorithm due to Knuth,
+ * Morris, and Pratt [1]. Their algorithm avoids the explicit
+ * computation of the transition function DELTA altogether. Its
+ * matching time is O(n), for n being length(text), using just an
+ * auxiliary function PI[1..m], for m being length(pattern),
+ * precomputed from the pattern in time O(m). The array PI allows
+ * the transition function DELTA to be computed efficiently
+ * "on the fly" as needed. Roughly speaking, for any state
+ * "q" = 0,1,...,m and any character "a" in SIGMA, the value
+ * PI["q"] contains the information that is independent of "a" and
+ * is needed to compute DELTA("q", "a") [2]. Since the array PI
+ * has only m entries, whereas DELTA has O(m|SIGMA|) entries, we
+ * save a factor of |SIGMA| in the preprocessing time by computing
+ * PI rather than DELTA.

+config BRIDGE
+ tristate "802.1d Ethernet Bridging"
+ ---help---
+ If you say Y here, then your Linux box will be able to act as an
+ Ethernet bridge, which means that the different Ethernet segments it
+ is connected to will appear as one Ethernet to the participants.
+ Several such bridges can work together to create even larger
+ networks of Ethernets using the IEEE 802.1 spanning tree algorithm.
+ As this is a standard, Linux bridges will cooperate properly with
+ other third party bridge products.
+
+ In order to use the Ethernet bridge, you'll need the bridge
+ configuration tools; see <file:Documentation/networking/bridge.txt>
+ for location. Please read the Bridge mini-HOWTO for more
+ information.
+
+ If you enable iptables support along with the bridge support then you
+ turn your bridge into a bridging IP firewall.
+ iptables will then see the IP packets being bridged, so you need to
+ take this into account when setting up your firewall rules.
+ Enabling arptables support when bridging will let arptables see
+ bridged ARP traffic in the arptables FORWARD chain.
+
+ To compile this code as a module, choose M here: the module
+ will be called bridge.
+
+ If unsure, say N.

+ BIC-TCP is a sender-side only change that ensures a linear RTT
+ fairness under large windows while offering both scalability and
+ bounded TCP-friendliness. The protocol combines two schemes
+ called additive increase and binary search increase. When the
+ congestion window is large, additive increase with a large

+ TCP Westwood+ is a sender-side only modification of the TCP Reno
+ protocol stack that optimizes the performance of TCP congestion
+ control. It is based on end-to-end bandwidth estimation to set
+ congestion window and slow start threshold after a congestion
+ episode. Using this estimation, TCP Westwood+ adaptively sets a

- * o To avoid the performance penalty imposed by increasing cwnd
- * only every-other RTT during slow start, we increase during
- * every RTT during slow start, just like Reno.
- * o Largely to allow continuous cwnd growth during slow start,
- * we use the rate at which ACKs come back as the "actual"
- * rate, rather than the rate at which data is sent.
- * o To speed convergence to the right rate, we set the cwnd
- * to achieve the right ("actual") rate when we exit slow start.
- * o To filter out the noise caused by delayed ACKs, we use the
- * minimum RTT sample observed during the last RTT to calculate
- * the actual rate.
- * o When the sender re-starts from idle, it waits until it has
- * received ACKs for an entire flight of new data before making
- * a cwnd adjustment decision. The original Vegas implementation
- * assumed senders never went idle.

+ * Linux in any way. Linux already recovers from losses quite well,
+ * using fine-grained timers, NewReno, and FACK.
+ * o To avoid the performance penalty imposed by increasing cwnd
+ * only every-other RTT during slow start, we increase during
+ * every RTT during slow start, just like Reno.
+ * o Largely to allow continuous cwnd growth during slow start,
+ * we use the rate at which ACKs come back as the "actual"
+ * rate, rather than the rate at which data is sent.
+ * o To speed convergence to the right rate, we set the cwnd
+ * to achieve the right ("actual") rate when we exit slow start.
+ * o To filter out the noise caused by delayed ACKs, we use the
+ * minimum RTT sample observed during the last RTT to calculate
+ * the actual rate.
+ * o When the sender re-starts from idle, it waits until it has
+ * received ACKs for an entire flight of new data before making
+ * a cwnd adjustment decision. The original Vegas implementation
+ * assumed senders never went idle.

+ ---help---
+ This is support for the Novell networking protocol, IPX, commonly
+ used for local networks of Windows machines. You need it if you
+ want to access Novell NetWare file or print servers using the Linux
+ Novell client ncpfs (available from
+ <ftp://platan.vc.cvut.cz/pub/linux/ncpfs/>) or from
+ within the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO,
+ available from <http://www.tldp.org/docs.html#howto>). In order
+ to do the former, you'll also have to say Y to "NCP file system
+ support", below.
+
+ IPX is similar in scope to IP, while SPX, which runs on top of IPX,
+ is similar to TCP. There is also experimental support for SPX in
+ Linux (see "SPX networking", below).
+
+ To turn your Linux box into a fully featured NetWare file server and
+ IPX router, say Y here and fetch either lwared from
+ <ftp://ibiblio.org/pub/Linux/system/network/daemons/> or
+ mars_nwe from <ftp://www.compu-art.de/mars_nwe/>. For more
+ information, read the IPX-HOWTO available from
+ <http://www.tldp.org/docs.html#howto>.
+
+ General information about how to connect Linux, Windows machines and
+ Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
+
+ The IPX driver would enlarge your kernel by about 16 KB. To compile
+ this driver as a module, choose M here: the module will be called ipx.
+ Unless you want to integrate your Linux box with a local Novell
+ network, say N.

+ ---help---
+ When the kernel has several packets to send out over a network
+ device, it has to decide which ones to send first, which ones to
+ delay, and which ones to drop. This is the job of the packet
+ scheduler, and several different algorithms for how to do this
+ "fairly" have been proposed.
+
+ If you say N here, you will get the standard packet scheduler, which
+ is a FIFO (first come, first served). If you say Y here, you will be
+ able to choose from among several alternative algorithms which can
+ then be attached to different network devices. This is useful for
+ example if some of your network devices are real time devices that
+ need a certain minimum data flow rate, or if you need to limit the
+ maximum data flow rate for traffic which matches specified criteria.
+ This code is considered to be experimental.
+
+ To administer these schedulers, you'll need the user-level utilities
+ from the package iproute2+tc at <ftp://ftp.tux.org/pub/net/ip-routing/>.
+ That package also contains some documentation; for more, check out
+ <http://snafu.freedom.org/linux2.2/iproute-notes.html>.
+
+ This Quality of Service (QoS) support will enable you to use
+ Differentiated Services (diffserv) and Resource Reservation Protocol
+ (RSVP) on your Linux router if you also say Y to "QoS support",
+ "Packet classifier API" and to some classifiers below. Documentation
+ and software is at <http://diffserv.sourceforge.net/>.
+
+ If you say Y here and to "/proc file system" below, you will be able
+ to read status information about packet schedulers from the file
+ /proc/net/psched.

+ Wide Area Networks (WANs), such as X.25, frame relay and leased

+ achievable with commonly used asynchronous modem connections.
+ Usually, a quite expensive external device called a `WAN router' is

+

+ With relatively inexpensive WAN interface cards available on the
+ market, a perfectly usable router can be built for less than half
+ the price of an external router. If you have one of those cards and
+ wish to use your Linux box as a WAN router, say Y here and also to
+ the WAN driver for your card, below. You will then need the
+ wan-tools package which is available from <ftp://ftp.sangoma.com/>.
+ Read <file:Documentation/networking/wan-router.txt> for more
+ information.
+
+ To compile WAN routing support as a module, choose M here: the
+ module will be called wanrouter.

+ ---help---
+ X.25 is a set of standardized network protocols, similar in scope to
+ frame relay; the one physical line from your box to the X.25 network
+ entry point can carry several logical point-to-point connections
+ (called "virtual circuits") to other computers connected to the X.25
+ network. Governments, banks, and other organizations tend to use it
+ to connect to each other or to form Wide Area Networks (WANs). Many
+ countries have public X.25 networks. X.25 consists of two
+ protocols: the higher level Packet Layer Protocol (PLP) (say Y here
+ if you want that) and the lower level data link layer protocol LAPB
+ (say Y to "LAPB Data Link Driver" below if you want that).
+
+ You can read more about X.25 at <http://www.sangoma.com/x25.htm> and
+ <http://www.cisco.com/univercd/cc/td/doc/product/software/ios11/cbook/cx25.htm>.
+ Information about X.25 for Linux is contained in the files
+ <file:Documentation/networking/x25.txt> and
+ <file:Documentation/networking/x25-iface.txt>.
+
+ One connects to an X.25 network either with a dedicated network card
+ using the X.21 protocol (not yet supported by Linux) or one can do
+ X.25 over a standard telephone line using an ordinary modem (say Y
+ to "X.25 async driver" below) or over Ethernet using an ordinary
+ Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link
+ Driver" and "LAPB over Ethernet driver" below).
