+MMUPageSize: 4 kB
+
+The first of these lines shows the same information as is displayed for the
+mapping in /proc/PID/maps. The remaining lines show the size of the mapping,
+the amount of the mapping that is currently resident in RAM, the "proportional
+set size” (divide each shared page by the number of processes sharing it), the
+number of clean and dirty shared pages in the mapping, and the number of clean
+and dirty private pages in the mapping. The "Referenced" indicates the amount
+of memory currently marked as referenced or accessed.
+
+This file is only present if the CONFIG_MMU kernel configuration option is
+enabled.
1.2 Kernel data
---------------
Similar to the process entries, the kernel data files give information about
the running kernel. The files used to obtain this information are contained in
-/proc and are listed in Table 1-4. Not all of these will be present in your
+/proc and are listed in Table 1-5. Not all of these will be present in your
system. It depends on the kernel configuration and the loaded modules, which
files are there, and which are missing.

+Using gcov with the Linux kernel
+================================
+
+1. Introduction
+2. Preparation
+3. Customization
+4. Files
+5. Modules
+6. Separated build and test machines
+7. Troubleshooting
+Appendix A: sample script: gather_on_build.sh
+Appendix B: sample script: gather_on_test.sh
+
+
+1. Introduction
+===============
+
+gcov profiling kernel support enables the use of GCC's coverage testing
+tool gcov [1] with the Linux kernel. Coverage data of a running kernel
+is exported in gcov-compatible format via the "gcov" debugfs directory.
+To get coverage data for a specific file, change to the kernel build
+directory and use gcov with the -o option as follows (requires root):
+
+# cd /tmp/linux-out
+# gcov -o /sys/kernel/debug/gcov/tmp/linux-out/kernel spinlock.c
+
+This will create source code files annotated with execution counts
+in the current directory. In addition, graphical gcov front-ends such
+as lcov [2] can be used to automate the process of collecting data
+for the entire kernel and provide coverage overviews in HTML format.
+
+Possible uses:
+
+* debugging (has this line been reached at all?)
+* test improvement (how do I change my test to cover these lines?)
+* minimizing kernel configurations (do I need this option if the
+ associated code is never run?)
+
+--
+
+[1] http://gcc.gnu.org/onlinedocs/gcc/Gcov.html
+[2] http://ltp.sourceforge.net/coverage/lcov.php
+
+
+2. Preparation
+==============
+
+Configure the kernel with:
+
+ CONFIG_DEBUGFS=y
+ CONFIG_GCOV_KERNEL=y
+
+and to get coverage data for the entire kernel:
+
+ CONFIG_GCOV_PROFILE_ALL=y
+
+Note that kernels compiled with profiling flags will be significantly
+larger and run slower. Also CONFIG_GCOV_PROFILE_ALL may not be supported
+on all architectures.
+
+Profiling data will only become accessible once debugfs has been
+mounted:
+
+ mount -t debugfs none /sys/kernel/debug
+
+
+3. Customization
+================
+
+To enable profiling for specific files or directories, add a line
+similar to the following to the respective kernel Makefile:
+
+ For a single file (e.g. main.o):
+ GCOV_PROFILE_main.o := y
+
+ For all files in one directory:
+ GCOV_PROFILE := y
+
+To exclude files from being profiled even when CONFIG_GCOV_PROFILE_ALL
+is specified, use:
+
+ GCOV_PROFILE_main.o := n
+ and:
+ GCOV_PROFILE := n
+
+Only files which are linked to the main kernel image or are compiled as
+kernel modules are supported by this mechanism.
+
+
+4. Files
+========
+
+The gcov kernel support creates the following files in debugfs:
+
+ /sys/kernel/debug/gcov
+ Parent directory for all gcov-related files.
+
+ /sys/kernel/debug/gcov/reset
+ Global reset file: resets all coverage data to zero when
+ written to.
+
+ /sys/kernel/debug/gcov/path/to/compile/dir/file.gcda
+ The actual gcov data file as understood by the gcov
+ tool. Resets file coverage data to zero when written to.
+
+ /sys/kernel/debug/gcov/path/to/compile/dir/file.gcno
+ Symbolic link to a static data file required by the gcov
+ tool. This file is generated by gcc when compiling with
+ option -ftest-coverage.
+
+
+5. Modules
+==========
+
+Kernel modules may contain cleanup code which is only run during
+module unload time. The gcov mechanism provides a means to collect
+coverage data for such code by keeping a copy of the data associated
+with the unloaded module. This data remains available through debugfs.
+Once the module is loaded again, the associated coverage counters are
+initialized with the data from its previous instantiation.
+
+This behavior can be deactivated by specifying the gcov_persist kernel
+parameter:
+
+ gcov_persist=0
+
+At run-time, a user can also choose to discard data for an unloaded
+module by writing to its data file or the global reset file.
+
+
+6. Separated build and test machines
+====================================
+
+The gcov kernel profiling infrastructure is designed to work out-of-the
+box for setups where kernels are built and run on the same machine. In
+cases where the kernel runs on a separate machine, special preparations
+must be made, depending on where the gcov tool is used:
+
+a) gcov is run on the TEST machine
+
+The gcov tool version on the test machine must be compatible with the
+gcc version used for kernel build. Also the following files need to be
+copied from build to test machine:
+
+from the source tree:
+ - all C source files + headers
+
+from the build tree:
+ - all C source files + headers
+ - all .gcda and .gcno files
+ - all links to directories
+
+It is important to note that these files need to be placed into the
+exact same file system location on the test machine as on the build
+machine. If any of the path components is symbolic link, the actual
+directory needs to be used instead (due to make's CURDIR handling).
+
+b) gcov is run on the BUILD machine
+
+The following files need to be copied after each test case from test
+to build machine:
+
+from the gcov directory in sysfs:
+ - all .gcda files
+ - all links to .gcno files
+
+These files can be copied to any location on the build machine. gcov
+must then be called with the -o option pointing to that directory.
+
+Example directory setup on the build machine:
+
+ /tmp/linux: kernel source tree
+ /tmp/out: kernel build directory as specified by make O=
+ /tmp/coverage: location of the files copied from the test machine
+
+ [user@build] cd /tmp/out
+ [user@build] gcov -o /tmp/coverage/tmp/out/init main.c
+
+
+7. Troubleshooting
+==================
+
+Problem: Compilation aborts during linker step.
+Cause: Profiling flags are specified for source files which are not
+ linked to the main kernel or which are linked by a custom
+ linker procedure.
+Solution: Exclude affected source files from profiling by specifying
+ GCOV_PROFILE := n or GCOV_PROFILE_basename.o := n in the
+ corresponding Makefile.
+
+
+Appendix A: gather_on_build.sh
+==============================

+Overview
+--------
+
+LinuxPPS provides a programming interface (API) to define in the
+system several PPS sources.
+
+PPS means "pulse per second" and a PPS source is just a device which
+provides a high precision signal each second so that an application
+can use it to adjust system clock time.
+
+A PPS source can be connected to a serial port (usually to the Data
+Carrier Detect pin) or to a parallel port (ACK-pin) or to a special
+CPU's GPIOs (this is the common case in embedded systems) but in each
+case when a new pulse arrives the system must apply to it a timestamp
+and record it for userland.
+
+Common use is the combination of the NTPD as userland program, with a
+GPS receiver as PPS source, to obtain a wallclock-time with
+sub-millisecond synchronisation to UTC.
+
+
+RFC considerations
+------------------
+
+While implementing a PPS API as RFC 2783 defines and using an embedded
+CPU GPIO-Pin as physical link to the signal, I encountered a deeper
+problem:
+
+ At startup it needs a file descriptor as argument for the function
+ time_pps_create().
+
+This implies that the source has a /dev/... entry. This assumption is
+ok for the serial and parallel port, where you can do something
+useful besides(!) the gathering of timestamps as it is the central
+task for a PPS-API. But this assumption does not work for a single
+purpose GPIO line. In this case even basic file-related functionality
+(like read() and write()) makes no sense at all and should not be a
+precondition for the use of a PPS-API.
+
+The problem can be simply solved if you consider that a PPS source is
+not always connected with a GPS data source.
+
+So your programs should check if the GPS data source (the serial port
+for instance) is a PPS source too, and if not they should provide the
+possibility to open another device as PPS source.
+
+In LinuxPPS the PPS sources are simply char devices usually mapped
+into files /dev/pps0, /dev/pps1, etc..
+
+
+Coding example
+--------------
+
+To register a PPS source into the kernel you should define a struct
+pps_source_info_s as follows:
+
+ static struct pps_source_info pps_ktimer_info = {
+ .name = "ktimer",
+ .path = "",
+ .mode = PPS_CAPTUREASSERT | PPS_OFFSETASSERT | \
+ PPS_ECHOASSERT | \
+ PPS_CANWAIT | PPS_TSFMT_TSPEC,
+ .echo = pps_ktimer_echo,
+ .owner = THIS_MODULE,
+ };
+
+and then calling the function pps_register_source() in your
+intialization routine as follows:
+
+ source = pps_register_source(&pps_ktimer_info,
+ PPS_CAPTUREASSERT | PPS_OFFSETASSERT);
+
+The pps_register_source() prototype is:
+
+ int pps_register_source(struct pps_source_info_s *info, int default_params)
+
+where "info" is a pointer to a structure that describes a particular
+PPS source, "default_params" tells the system what the initial default
+parameters for the device should be (it is obvious that these parameters
+must be a subset of ones defined in the struct
+pps_source_info_s which describe the capabilities of the driver).
+
+Once you have registered a new PPS source into the system you can
+signal an assert event (for example in the interrupt handler routine)
+just using:
+
+ pps_event(source, &ts, PPS_CAPTUREASSERT, ptr)
+
+where "ts" is the event's timestamp.
+
+The same function may also run the defined echo function
+(pps_ktimer_echo(), passing to it the "ptr" pointer) if the user
+asked for that... etc..
+
+Please see the file drivers/pps/clients/ktimer.c for example code.
+
+
+SYSFS support
+-------------
+
+If the SYSFS filesystem is enabled in the kernel it provides a new class:
+
+ $ ls /sys/class/pps/
+ pps0/ pps1/ pps2/
+
+Every directory is the ID of a PPS sources defined in the system and
+inside you find several files:
+
+ $ ls /sys/class/pps/pps0/
+ assert clear echo mode name path subsystem@ uevent
+
+Inside each "assert" and "clear" file you can find the timestamp and a
+sequence number:
+
+ $ cat /sys/class/pps/pps0/assert
+ 1170026870.983207967#8
+
+Where before the "#" is the timestamp in seconds; after it is the
+sequence number. Other files are:
+
+* echo: reports if the PPS source has an echo function or not;
+
+* mode: reports available PPS functioning modes;
+
+* name: reports the PPS source's name;
+
+* path: reports the PPS source's device path, that is the device the
+ PPS source is connected to (if it exists).
+
+
+Testing the PPS support
+-----------------------
+
+In order to test the PPS support even without specific hardware you can use
+the ktimer driver (see the client subsection in the PPS configuration menu)
+and the userland tools provided into Documentaion/pps/ directory.
+
+Once you have enabled the compilation of ktimer just modprobe it (if
+not statically compiled):
+
+ # modprobe ktimer
+
+and the run ppstest as follow:
+
+ $ ./ppstest /dev/pps0
+ trying PPS source "/dev/pps1"
+ found PPS source "/dev/pps1"
+ ok, found 1 source(s), now start fetching data...
+ source 0 - assert 1186592699.388832443, sequence: 364 - clear 0.000000000, sequence: 0

+ source 0 - assert 1186592701.389032765, sequence: 366 - clear 0.000000000, sequence: 0

+The rfkill subsystem has a concept of "hard" and "soft" block, which
+differ little in their meaning (block == transmitters off) but rather in
+whether they can be changed or not:
+ - hard block: read-only radio block that cannot be overriden by software
+ - soft block: writable radio block (need not be readable) that is set by
+ the system software.
2. Implementation details
-The rfkill subsystem is composed of various components: the rfkill class, the
-rfkill-input module (an input layer handler), and some specific input layer
-events.
+The rfkill subsystem is composed of three main components:
+ * the rfkill core,
+ * the deprecated rfkill-input module (an input layer handler, being
+ replaced by userspace policy code) and
+ * the rfkill drivers.
-The rfkill class is provided for kernel drivers to register their radio
-transmitter with the kernel, provide methods for turning it on and off and,
-optionally, letting the system know about hardware-disabled states that may
-be implemented on the device. This code is enabled with the CONFIG_RFKILL
-Kconfig option, which drivers can "select".
+The rfkill core provides API for kernel drivers to register their radio
+transmitter with the kernel, methods for turning it on and off and, letting
+the system know about hardware-disabled states that may be implemented on
+the device.
-The rfkill class code also notifies userspace of state changes, this is
-achieved via uevents. It also provides some sysfs files for userspace to
-check the status of radio transmitters. See the "Userspace support" section
-below.
-
-
-The rfkill-input code implements a basic response to rfkill buttons -- it
-implements turning on/off all devices of a certain class (or all).
+The rfkill core code also notifies userspace of state changes, and provides
+ways for userspace to query the current states. See the "Userspace support"
+section below.
When the device is hard-blocked (either by a call to rfkill_set_hw_state()
-or from query_hw_block) set_block() will be invoked but drivers can well
-ignore the method call since they can use the return value of the function
-rfkill_set_hw_state() to sync the software state instead of keeping track
-of calls to set_block().

+block, but drivers can ignore the method call since they can use the return
+value of the function rfkill_set_hw_state() to sync the software state
+instead of keeping track of calls to set_block(). In fact, drivers should
+use the return value of rfkill_set_hw_state() unless the hardware actually
+keeps track of soft and hard block separately.
-The entire functionality is spread over more than one subsystem:
-
- * The kernel input layer generates KEY_WWAN, KEY_WLAN etc. and
- SW_RFKILL_ALL -- when the user presses a button. Drivers for radio
- transmitters generally do not register to the input layer, unless the
- device really provides an input device (i.e. a button that has no
- effect other than generating a button press event)
-
- * The rfkill-input code hooks up to these events and switches the soft-block
- of the various radio transmitters, depending on the button type.
-
- * The rfkill drivers turn off/on their transmitters as requested.
-
- * The rfkill class will generate userspace notifications (uevents) to tell
- userspace what the current state is.

5. Userspace support
-The following sysfs entries exist for every rfkill device:

+linux/rfkill.h, with one ioctl that allows turning off the deprecated input
+handler in the kernel for the transition period.
+
+Except for the one ioctl, communication with the kernel is done via read()

+system. Also, it is possible to switch all rfkill drivers (or all drivers of
+a specified type) into a state which also updates the default state for

+After an application opens /dev/rfkill, it can read the current state of

+ HP iLO2 NMI Watchdog Driver
+ NMI sourcing for iLO2 based ProLiant Servers
+ Documentation and Driver by
+ Thomas Mingarelli <thomas.mingarelli@hp.com>
+
+ The HP iLO2 NMI Watchdog driver is a kernel module that provides basic
+ watchdog functionality and the added benefit of NMI sourcing. Both the
+ watchdog functionality and the NMI sourcing capability need to be enabled
+ by the user. Remember that the two modes are not dependant on one another.
+ A user can have the NMI sourcing without the watchdog timer and vice-versa.
+
+ Watchdog functionality is enabled like any other common watchdog driver. That
+ is, an application needs to be started that kicks off the watchdog timer. A
+ basic application exists in the Documentation/watchdog/src directory called
+ watchdog-test.c. Simply compile the C file and kick it off. If the system
+ gets into a bad state and hangs, the HP ProLiant iLO 2 timer register will
+ not be updated in a timely fashion and a hardware system reset (also known as
+ an Automatic Server Recovery (ASR)) event will occur.
+
+ The hpwdt driver also has three (3) module parameters. They are the following:
+
+ soft_margin - allows the user to set the watchdog timer value
+ allow_kdump - allows the user to save off a kernel dump image after an NMI
+ nowayout - basic watchdog parameter that does not allow the timer to
+ be restarted or an impending ASR to be escaped.
+
+ NOTE: More information about watchdog drivers in general, including the ioctl
+ interface to /dev/watchdog can be found in
+ Documentation/watchdog/watchdog-api.txt and Documentation/IPMI.txt.
+
+ The NMI sourcing capability is disabled when the driver discovers that the
+ nmi_watchdog is turned on (nmi_watchdog = 1). This is due to the inability to
+ distinguish between "NMI Watchdog Ticks" and "HW generated NMI events" in the
+ Linux kernel. What this means is that the hpwdt nmi handler code is called
+ each time the NMI signal fires off. This could amount to several thousands of
+ NMIs in a matter of seconds. If a user sees the Linux kernel's "dazed and
+ confused" message in the logs or if the system gets into a hung state, then
+ the user should reboot with nmi_watchdog=0.
+
+ 1. If the kernel has not been booted with nmi_watchdog turned off then
+ edit /boot/grub/menu.lst and place the nmi_watchdog=0 at the end of the
+ currently booting kernel line.
+ 2. reboot the sever
+
+ Now, the hpwdt can successfully receive and source the NMI and provide a log
+ message that details the reason for the NMI (as determined by the HP BIOS).
+
+ Below is a list of NMIs the HP BIOS understands along with the associated
+ code (reason):
+
+ No source found 00h
+
+ Uncorrectable Memory Error 01h
+
+ ASR NMI 1Bh
+
+ PCI Parity Error 20h
+
+ NMI Button Press 27h
+
+ SB_BUS_NMI 28h
+
+ ILO Doorbell NMI 29h

+ ILO IOP NMI 2Ah
+
+ ILO Watchdog NMI 2Bh
+

+
+ Front Side Bus NMI 2Dh
+
+ PCI Express Error 2Fh
+
+ DMA controller NMI 30h
+
+ Hypertransport/CSI Error 31h

-/* Core file format: The core file is written in such a way that gdb
- can understand it and provide useful information to the user (under
- linux we use the 'trad-core' bfd). There are quite a number of
- obstacles to being able to view the contents of the floating point
- registers, and until these are solved you will not be able to view the
- contents of them. Actually, you can read in the core file and look at
- the contents of the user struct to find out what the floating point
- registers contain.
- The actual file contents are as follows:
- UPAGE: 1 page consisting of a user struct that tells gdb what is present
- in the file. Directly after this is a copy of the task_struct, which
- is currently not used by gdb, but it may come in useful at some point.
- All of the registers are stored as part of the upage. The upage should
- always be only one page.
- DATA: The data area is stored. We use current->end_text to
- current->brk to pick up all of the user variables, plus any memory
- that may have been malloced. No attempt is made to determine if a page
- is demand-zero or if a page is totally unused, we just cover the entire
- range. All of the addresses are rounded in such a way that an integral
- number of pages is written.
- STACK: We need the stack information in order to get a meaningful
- backtrace. We need to write the data from (esp) to
- current->start_stack, so we round each of these off in order to be able
- to write an integer number of pages.
- The minimum core file size is 3 pages, or 12288 bytes.

* resources. This will likely be replaced when we better understand the
* kernel/user requirements.
*
- * At boot time, the kernel permanently reserves a fixed number of
- * CBRs/DSRs for each cpu to use. The resources are all taken from
- * the GRU chiplet 1 on the blade. This leaves the full set of resources
- * of chiplet 0 available to be allocated to a single user.
+ * Blade percpu resources reserved for kernel use. These resources are
+ * reserved whenever the the kernel context for the blade is loaded. Note
+ * that the kernel context is not guaranteed to be always available. It is
+ * loaded on demand & can be stolen by a user if the user demand exceeds the
+ * kernel demand. The kernel can always reload the kernel context but
+ * a SLEEP may be required!!!.
+ *
+ * Async Overview:
+ *
+ * Each blade has one "kernel context" that owns GRU kernel resources
+ * located on the blade. Kernel drivers use GRU resources in this context
+ * for sending messages, zeroing memory, etc.
+ *
+ * The kernel context is dynamically loaded on demand. If it is not in
+ * use by the kernel, the kernel context can be unloaded & given to a user.
+ * The kernel context will be reloaded when needed. This may require that
+ * a context be stolen from a user.
+ * NOTE: frequent unloading/reloading of the kernel context is
+ * expensive. We are depending on batch schedulers, cpusets, sane
+ * drivers or some other mechanism to prevent the need for frequent
+ * stealing/reloading.
+ *
+ * The kernel context consists of two parts:
+ * - 1 CB & a few DSRs that are reserved for each cpu on the blade.
+ * Each cpu has it's own private resources & does not share them
+ * with other cpus. These resources are used serially, ie,
+ * locked, used & unlocked on each call to a function in
+ * grukservices.
+ * (Now that we have dynamic loading of kernel contexts, I
+ * may rethink this & allow sharing between cpus....)
+ *
+ * - Additional resources can be reserved long term & used directly
+ * by UV drivers located in the kernel. Drivers using these GRU
+ * resources can use asynchronous GRU instructions that send
+ * interrupts on completion.
+ * - these resources must be explicitly locked/unlocked
+ * - locked resources prevent (obviously) the kernel
+ * context from being unloaded.
+ * - drivers using these resource directly issue their own
+ * GRU instruction and must wait/check completion.
+ *
+ * When these resources are reserved, the caller can optionally
+ * associate a wait_queue with the resources and use asynchronous
+ * GRU instructions. When an async GRU instruction completes, the
+ * driver will do a wakeup on the event.

+ * Vendor Support: 911
+ * Board: Some Intel ICHx based motherboards
+ * iTCO chipset: ICH7+
+ *
+ * Some Intel motherboards have a broken BIOS implementation: i.e.
+ * the SMI handler clear's the TIMEOUT bit in the TC01_STS register
+ * and does not reload the time. Thus the TCO watchdog does not reboot
+ * the system.
+ *
+ * These are the conclusions of Andriy Gapon <avg@icyb.net.ua> after
+ * debugging: the SMI handler is quite simple - it tests value in
+ * TCO1_CNT against 0x800, i.e. checks TCO_TMR_HLT. If the bit is set
+ * the handler goes into an infinite loop, apparently to allow the
+ * second timeout and reboot. Otherwise it simply clears TIMEOUT bit
+ * in TCO1_STS and that's it.
+ * So the logic seems to be reversed, because it is hard to see how
+ * TIMEOUT can get set to 1 and SMI generated when TCO_TMR_HLT is set
+ * (other than a transitional effect).
+ *
+ * The only fix found to get the motherboard(s) to reboot is to put
+ * the glb_smi_en bit to 0. This is a dirty hack that bypasses the
+ * broken code by disabling Global SMI.
+ *
+ * WARNING: globally disabling SMI could possibly lead to dramatic
+ * problems, especially on laptops! I.e. various ACPI things where
+ * SMI is used for communication between OS and firmware.
+ *
+ * Don't use this fix if you don't need to!!!
