+
+Introduction
+============
+This file documents the features and components of the SCSI FC Transport.
+It also provides documents the API between the transport and FC LLDDs.
+The FC transport can be found at:
+ drivers/scsi/scsi_transport_fc.c
+ include/scsi/scsi_transport_fc.h
+ include/scsi/scsi_netlink_fc.h

+
+FC Remote Ports (rports)
+========================================================================
+<< To Be Supplied >>
+
+
+FC Virtual Ports (vports)
+========================================================================
+
+Overview:
+-------------------------------
+
+ New FC standards have defined mechanisms which allows for a single physical
+ port to appear on as multiple communication ports. Using the N_Port Id
+ Virtualization (NPIV) mechanism, a point-to-point connection to a Fabric
+ can be assigned more than 1 N_Port_ID. Each N_Port_ID appears as a
+ separate port to other endpoints on the fabric, even though it shares one
+ physical link to the switch for communication. Each N_Port_ID can have a
+ unique view of the fabric based on fabric zoning and array lun-masking
+ (just like a normal non-NPIV adapter). Using the Virtual Fabric (VF)
+ mechanism, adding a fabric header to each frame allows the port to
+ interact with the Fabric Port to join multiple fabrics. The port will
+ obtain an N_Port_ID on each fabric it joins. Each fabric will have its
+ own unique view of endpoints and configuration parameters. NPIV may be
+ used together with VF so that the port can obtain multiple N_Port_IDs
+ on each virtual fabric.
+
+ The FC transport is now recognizing a new object - a vport. A vport is
+ an entity that has a world-wide unique World Wide Port Name (wwpn) and
+ World Wide Node Name (wwnn). The transport also allows for the FC4's to
+ be specified for the vport, with FCP_Initiator being the primary role
+ expected. Once instantiated by one of the above methods, it will have a
+ distinct N_Port_ID and view of fabric endpoints and storage entities.
+ The fc_host associated with the physical adapter will export the ability
+ to create vports. The transport will create the vport object within the
+ Linux device tree, and instruct the fc_host's driver to instantiate the
+ virtual port. Typically, the driver will create a new scsi_host instance
+ on the vport, resulting in a unique <H,C,T,L> namespace for the vport.
+ Thus, whether a FC port is based on a physical port or on a virtual port,
+ each will appear as a unique scsi_host with its own target and lun space.
+
+ Note: At this time, the transport is written to create only NPIV-based
+ vports. However, consideration was given to VF-based vports and it
+ should be a minor change to add support if needed. The remaining
+ discussion will concentrate on NPIV.
+
+ Note: World Wide Name assignment (and uniqueness guarantees) are left
+ up to an administrative entity controling the vport. For example,
+ if vports are to be associated with virtual machines, a XEN mgmt
+ utility would be responsible for creating wwpn/wwnn's for the vport,
+ using it's own naming authority and OUI. (Note: it already does this
+ for virtual MAC addresses).
+
+
+Device Trees and Vport Objects:
+-------------------------------
+
+ Today, the device tree typically contains the scsi_host object,
+ with rports and scsi target objects underneath it. Currently the FC
+ transport creates the vport object and places it under the scsi_host
+ object corresponding to the physical adapter. The LLDD will allocate
+ a new scsi_host for the vport and link it's object under the vport.
+ The remainder of the tree under the vports scsi_host is the same
+ as the non-NPIV case. The transport is written currently to easily
+ allow the parent of the vport to be something other than the scsi_host.
+ This could be used in the future to link the object onto a vm-specific
+ device tree. If the vport's parent is not the physical port's scsi_host,
+ a symbolic link to the vport object will be placed in the physical
+ port's scsi_host.
+
+ Here's what to expect in the device tree :
+ The typical Physical Port's Scsi_Host:
+ /sys/devices/.../host17/
+ and it has the typical decendent tree:
+ /sys/devices/.../host17/rport-17:0-0/target17:0:0/17:0:0:0:
+ and then the vport is created on the Physical Port:
+ /sys/devices/.../host17/vport-17:0-0
+ and the vport's Scsi_Host is then created:
+ /sys/devices/.../host17/vport-17:0-0/host18
+ and then the rest of the tree progresses, such as:
+ /sys/devices/.../host17/vport-17:0-0/host18/rport-18:0-0/target18:0:0/18:0:0:0:
+
+ Here's what to expect in the sysfs tree :
+ scsi_hosts:
+ /sys/class/scsi_host/host17 physical port's scsi_host
+ /sys/class/scsi_host/host18 vport's scsi_host
+ fc_hosts:
+ /sys/class/fc_host/host17 physical port's fc_host
+ /sys/class/fc_host/host18 vport's fc_host
+ fc_vports:
+ /sys/class/fc_vports/vport-17:0-0 the vport's fc_vport
+ fc_rports:
+ /sys/class/fc_remote_ports/rport-17:0-0 rport on the physical port
+ /sys/class/fc_remote_ports/rport-18:0-0 rport on the vport
+
+
+Vport Attributes:
+-------------------------------
+
+ The new fc_vport class object has the following attributes
+
+ node_name: Read_Only
+ The WWNN of the vport
+
+ port_name: Read_Only
+ The WWPN of the vport
+
+ roles: Read_Only
+ Indicates the FC4 roles enabled on the vport.
+
+ symbolic_name: Read_Write
+ A string, appended to the driver's symbolic port name string, which
+ is registered with the switch to identify the vport. For example,
+ a hypervisor could set this string to "Xen Domain 2 VM 5 Vport 2",
+ and this set of identifiers can be seen on switch management screens
+ to identify the port.
+
+ vport_delete: Write_Only
+ When written with a "1", will tear down the vport.
+
+ vport_disable: Write_Only
+ When written with a "1", will transition the vport to a disabled.
+ state. The vport will still be instantiated with the Linux kernel,
+ but it will not be active on the FC link.
+ When written with a "0", will enable the vport.
+
+ vport_last_state: Read_Only
+ Indicates the previous state of the vport. See the section below on
+ "Vport States".
+
+ vport_state: Read_Only
+ Indicates the state of the vport. See the section below on
+ "Vport States".
+
+ vport_type: Read_Only
+ Reflects the FC mechanism used to create the virtual port.
+ Only NPIV is supported currently.
+
+
+ For the fc_host class object, the following attributes are added for vports:
+
+ max_npiv_vports: Read_Only
+ Indicates the maximum number of NPIV-based vports that the
+ driver/adapter can support on the fc_host.
+
+ npiv_vports_inuse: Read_Only
+ Indicates how many NPIV-based vports have been instantiated on the
+ fc_host.
+
+ vport_create: Write_Only
+ A "simple" create interface to instantiate a vport on an fc_host.
+ A "<WWPN>:<WWNN>" string is written to the attribute. The transport
+ then instantiates the vport object and calls the LLDD to create the
+ vport with the role of FCP_Initiator. Each WWN is specified as 16
+ hex characters and may *not* contain any prefixes (e.g. 0x, x, etc).
+
+ vport_delete: Write_Only
+ A "simple" delete interface to teardown a vport. A "<WWPN>:<WWNN>"
+ string is written to the attribute. The transport will locate the
+ vport on the fc_host with the same WWNs and tear it down. Each WWN
+ is specified as 16 hex characters and may *not* contain any prefixes
+ (e.g. 0x, x, etc).
+
+
+Vport States:
+-------------------------------
+
+ Vport instantiation consists of two parts:
+ - Creation with the kernel and LLDD. This means all transport and
+ driver data structures are built up, and device objects created.
+ This is equivalent to a driver "attach" on an adapter, which is
+ independent of the adapter's link state.
+ - Instantiation of the vport on the FC link via ELS traffic, etc.
+ This is equivalent to a "link up" and successfull link initialization.
+ Futher information can be found in the interfaces section below for
+ Vport Creation.
+
+ Once a vport has been instantiated with the kernel/LLDD, a vport state
+ can be reported via the sysfs attribute. The following states exist:
+
+ FC_VPORT_UNKNOWN - Unknown
+ An temporary state, typically set only while the vport is being
+ instantiated with the kernel and LLDD.
+
+ FC_VPORT_ACTIVE - Active
+ The vport has been successfully been created on the FC link.
+ It is fully functional.
+
+ FC_VPORT_DISABLED - Disabled
+ The vport instantiated, but "disabled". The vport is not instantiated
+ on the FC link. This is equivalent to a physical port with the
+ link "down".
+
+ FC_VPORT_LINKDOWN - Linkdown
+ The vport is not operational as the physical link is not operational.
+
+ FC_VPORT_INITIALIZING - Initializing
+ The vport is in the process of instantiating on the FC link.
+ The LLDD will set this state just prior to starting the ELS traffic
+ to create the vport. This state will persist until the vport is
+ successfully created (state becomes FC_VPORT_ACTIVE) or it fails
+ (state is one of the values below). As this state is transitory,
+ it will not be preserved in the "vport_last_state".
+
+ FC_VPORT_NO_FABRIC_SUPP - No Fabric Support
+ The vport is not operational. One of the following conditions were
+ encountered:
+ - The FC topology is not Point-to-Point
+ - The FC port is not connected to an F_Port
+ - The F_Port has indicated that NPIV is not supported.
+
+ FC_VPORT_NO_FABRIC_RSCS - No Fabric Resources
+ The vport is not operational. The Fabric failed FDISC with a status
+ indicating that it does not have sufficient resources to complete
+ the operation.
+
+ FC_VPORT_FABRIC_LOGOUT - Fabric Logout
+ The vport is not operational. The Fabric has LOGO'd the N_Port_ID
+ associated with the vport.
+
+ FC_VPORT_FABRIC_REJ_WWN - Fabric Rejected WWN
+ The vport is not operational. The Fabric failed FDISC with a status
+ indicating that the WWN's are not valid.
+
+ FC_VPORT_FAILED - VPort Failed
+ The vport is not operational. This is a catchall for all other
+ error conditions.
+
+
+ The following state table indicates the different state transitions:
+
+ State Event New State
+ --------------------------------------------------------------------
+ n/a Initialization Unknown
+ Unknown: Link Down Linkdown
+ Link Up & Loop No Fabric Support
+ Link Up & no Fabric No Fabric Support
+ Link Up & FLOGI response No Fabric Support
+ indicates no NPIV support
+ Link Up & FDISC being sent Initializing
+ Disable request Disable
+ Linkdown: Link Up Unknown
+ Initializing: FDISC ACC Active
+ FDISC LS_RJT w/ no resources No Fabric Resources
+ FDISC LS_RJT w/ invalid Fabric Rejected WWN
+ pname or invalid nport_id
+ FDISC LS_RJT failed for Vport Failed
+ other reasons
+ Link Down Linkdown
+ Disable request Disable
+ Disable: Enable request Unknown
+ Active: LOGO received from fabric Fabric Logout
+ Link Down Linkdown
+ Disable request Disable
+ Fabric Logout: Link still up Unknown
+
+ The following 4 error states all have the same transitions:
+ No Fabric Support:
+ No Fabric Resources:
+ Fabric Rejected WWN:
+ Vport Failed:
+ Disable request Disable
+ Link goes down Linkdown
+
+
+Transport <-> LLDD Interfaces :
+-------------------------------
+
+Vport support by LLDD:
+
+ The LLDD indicates support for vports by supplying a vport_create()
+ function in the transport template. The presense of this function will
+ cause the creation of the new attributes on the fc_host. As part of
+ the physical port completing its initialization relative to the
+ transport, it should set the max_npiv_vports attribute to indicate the
+ maximum number of vports the driver and/or adapter supports.
+
+
+Vport Creation:
+
+ The LLDD vport_create() syntax is:
+
+ int vport_create(struct fc_vport *vport, bool disable)
+
+ where:
+ vport: Is the newly allocated vport object
+ disable: If "true", the vport is to be created in a disabled stated.
+ If "false", the vport is to be enabled upon creation.
+
+ When a request is made to create a new vport (via sgio/netlink, or the
+ vport_create fc_host attribute), the transport will validate that the LLDD
+ can support another vport (e.g. max_npiv_vports > npiv_vports_inuse).
+ If not, the create request will be failed. If space remains, the transport
+ will increment the vport count, create the vport object, and then call the
+ LLDD's vport_create() function with the newly allocated vport object.
+
+ As mentioned above, vport creation is divided into two parts:
+ - Creation with the kernel and LLDD. This means all transport and
+ driver data structures are built up, and device objects created.
+ This is equivalent to a driver "attach" on an adapter, which is
+ independent of the adapter's link state.
+ - Instantiation of the vport on the FC link via ELS traffic, etc.
+ This is equivalent to a "link up" and successfull link initialization.
+
+ The LLDD's vport_create() function will not synchronously wait for both
+ parts to be fully completed before returning. It must validate that the
+ infrastructure exists to support NPIV, and complete the first part of
+ vport creation (data structure build up) before returning. We do not
+ hinge vport_create() on the link-side operation mainly because:
+ - The link may be down. It is not a failure if it is. It simply
+ means the vport is in an inoperable state until the link comes up.
+ This is consistent with the link bouncing post vport creation.
+ - The vport may be created in a disabled state.
+ - This is consistent with a model where: the vport equates to a
+ FC adapter. The vport_create is synonymous with driver attachment
+ to the adapter, which is independent of link state.
+
+ Note: special error codes have been defined to delineate infrastructure
+ failure cases for quicker resolution.
+
+ The expected behavior for the LLDD's vport_create() function is:
+ - Validate Infrastructure:
+ - If the driver or adapter cannot support another vport, whether
+ due to improper firmware, (a lie about) max_npiv, or a lack of
+ some other resource - return VPCERR_UNSUPPORTED.
+ - If the driver validates the WWN's against those already active on
+ the adapter and detects an overlap - return VPCERR_BAD_WWN.
+ - If the driver detects the topology is loop, non-fabric, or the
+ FLOGI did not support NPIV - return VPCERR_NO_FABRIC_SUPP.
+ - Allocate data structures. If errors are encountered, such as out
+ of memory conditions, return the respective negative Exxx error code.
+ - If the role is FCP Initiator, the LLDD is to :
+ - Call scsi_host_alloc() to allocate a scsi_host for the vport.
+ - Call scsi_add_host(new_shost, &vport->dev) to start the scsi_host
+ and bind it as a child of the vport device.
+ - Initializes the fc_host attribute values.
+ - Kick of further vport state transitions based on the disable flag and
+ link state - and return success (zero).
+
+ LLDD Implementers Notes:
+ - It is suggested that there be a different fc_function_templates for
+ the physical port and the virtual port. The physical port's template
+ would have the vport_create, vport_delete, and vport_disable functions,
+ while the vports would not.
+ - It is suggested that there be different scsi_host_templates
+ for the physical port and virtual port. Likely, there are driver
+ attributes, embedded into the scsi_host_template, that are applicable
+ for the physical port only (link speed, topology setting, etc). This
+ ensures that the attributes are applicable to the respective scsi_host.
+
+
+Vport Disable/Enable:
+
+ The LLDD vport_disable() syntax is:
+
+ int vport_disable(struct fc_vport *vport, bool disable)
+
+ where:
+ vport: Is vport to to be enabled or disabled
+ disable: If "true", the vport is to be disabled.
+ If "false", the vport is to be enabled.
+
+ When a request is made to change the disabled state on a vport, the
+ transport will validate the request against the existing vport state.
+ If the request is to disable and the vport is already disabled, the
+ request will fail. Similarly, if the request is to enable, and the
+ vport is not in a disabled state, the request will fail. If the request
+ is valid for the vport state, the transport will call the LLDD to
+ change the vport's state.
+
+ Within the LLDD, if a vport is disabled, it remains instantiated with
+ the kernel and LLDD, but it is not active or visible on the FC link in
+ any way. (see Vport Creation and the 2 part instantiation discussion).
+ The vport will remain in this state until it is deleted or re-enabled.
+ When enabling a vport, the LLDD reinstantiates the vport on the FC
+ link - essentially restarting the LLDD statemachine (see Vport States
+ above).
+
+
+Vport Deletion:
+
+ The LLDD vport_delete() syntax is:
+
+ int vport_delete(struct fc_vport *vport)
+
+ where:
+ vport: Is vport to delete
+
+ When a request is made to delete a vport (via sgio/netlink, or via the
+ fc_host or fc_vport vport_delete attributes), the transport will call
+ the LLDD to terminate the vport on the FC link, and teardown all other
+ datastructures and references. If the LLDD completes successfully,
+ the transport will teardown the vport objects and complete the vport
+ removal. If the LLDD delete request fails, the vport object will remain,
+ but will be in an indeterminate state.
+
+ Within the LLDD, the normal code paths for a scsi_host teardown should
+ be followed. E.g. If the vport has a FCP Initiator role, the LLDD
+ will call fc_remove_host() for the vports scsi_host, followed by
+ scsi_remove_host() and scsi_host_put() for the vports scsi_host.
+
+
+Other:
+ fc_host port_type attribute:
+ There is a new fc_host port_type value - FC_PORTTYPE_NPIV. This value
+ must be set on all vport-based fc_hosts. Normally, on a physical port,
+ the port_type attribute would be set to NPORT, NLPORT, etc based on the
+ topology type and existence of the fabric. As this is not applicable to
+ a vport, it makes more sense to report the FC mechanism used to create
+ the vport.
+
+ Driver unload:
+ FC drivers are required to call fc_remove_host() prior to calling
+ scsi_remove_host(). This allows the fc_host to tear down all remote
+ ports prior the scsi_host being torn down. The fc_remove_host() call
+ was updated to remove all vports for the fc_host as well.

- * Enable support for synchronous transfers. Target negotiated
- * synchronous transfers will be responded to. To initiate
- * a synchronous transfer request, call
- *
- * request_synchronous (hostno, target)
- *
- * from within KGDB.
- *
- * OPTION_ALWAYS_SYNCHRONOUS
- * Negotiate for synchronous transfers with every target after
- * driver initialization or a SCSI bus reset. This is a bit dangerous,
- * since there are some dain bramaged SCSI devices which will accept
- * SDTR messages but keep talking asynchronously.
- *
- * OPTION_DISCONNECT
- * Enable support for disconnect/reconnect. To change the

- * request_disconnect (hostno, allow)
- *
- * where allow is non-zero to allow, 0 to disallow.

- * If you really want to run 10MHz FAST SCSI-II transfers, you should
- * know that the NCR driver currently ignores parity information. Most
- * systems do 5MHz SCSI fine. I've seen a lot that have problems faster
- * than 8MHz. To play it safe, we only request 5MHz transfers.

- * If you'd rather get 10MHz transfers, edit sdtr_message and change

- * Design issues :
- * The cumulative latency needed to propagate a read/write request
- * through the file system, buffer cache, driver stacks, SCSI host, and
- * SCSI device is ultimately the limiting factor in throughput once we
- * have a sufficiently fast host adapter.
- *
- * So, to maximize performance we want to keep the ratio of latency to data
- * transfer time to a minimum by
- * 1. Minimizing the total number of commands sent (typical command latency
- * including drive and bus mastering host overhead is as high as 4.5ms)
- * to transfer a given amount of data.
- *
- * This is accomplished by placing no arbitrary limit on the number
- * of scatter/gather buffers supported, since we can transfer 1K
- * per scatter/gather buffer without Eric's cluster patches,
- * 4K with.
- *
- * 2. Minimizing the number of fatal interrupts serviced, since
- * fatal interrupts halt the SCSI I/O processor. Basically,
- * this means offloading the practical maximum amount of processing
- * to the SCSI chip.
- *
- * On the NCR53c810/820/720, this is accomplished by using
- * interrupt-on-the-fly signals when commands complete,
- * and only handling fatal errors and SDTR / WDTR messages
- * in the host code.
- *
- * On the NCR53c710, interrupts are generated as on the NCR53c8x0,
- * only the lack of a interrupt-on-the-fly facility complicates
- * things. Also, SCSI ID registers and commands are
- * bit fielded rather than binary encoded.
- *
- * On the NCR53c700 and NCR53c700-66, operations that are done via
- * indirect, table mode on the more advanced chips must be
- * replaced by calls through a jump table which
- * acts as a surrogate for the DSA. Unfortunately, this
- * will mean that we must service an interrupt for each
- * disconnect/reconnect.
- *
- * 3. Eliminating latency by pipelining operations at the different levels.
- *
- * This driver allows a configurable number of commands to be enqueued
- * for each target/lun combination (experimentally, I have discovered
- * that two seems to work best) and will ultimately allow for
- * SCSI-II tagged queuing.
- *
- *
- * Architecture :
- * This driver is built around a Linux queue of commands waiting to
- * be executed, and a shared Linux/NCR array of commands to start. Commands
- * are transferred to the array by the run_process_issue_queue() function
- * which is called whenever a command completes.
- *
- * As commands are completed, the interrupt routine is triggered,
- * looks for commands in the linked list of completed commands with
- * valid status, removes these commands from a list of running commands,
- * calls the done routine, and flags their target/luns as not busy.
- *
- * Due to limitations in the intelligence of the NCR chips, certain
- * concessions are made. In many cases, it is easier to dynamically
- * generate/fix-up code rather than calculate on the NCR at run time.
- * So, code is generated or fixed up for
- *
- * - Handling data transfers, using a variable number of MOVE instructions
- * interspersed with CALL MSG_IN, WHEN MSGIN instructions.
- *
- * The DATAIN and DATAOUT routines are separate, so that an incorrect
- * direction can be trapped, and space isn't wasted.
- *
- * It may turn out that we're better off using some sort
- * of table indirect instruction in a loop with a variable
- * sized table on the NCR53c710 and newer chips.
- *
- * - Checking for reselection (NCR53c710 and better)
- *
- * - Handling the details of SCSI context switches (NCR53c710 and better),
- * such as reprogramming appropriate synchronous parameters,
- * removing the dsa structure from the NCR's queue of outstanding
- * commands, etc.

- *
- * - With OPTION_DISCONNECT, on two systems under unknown circumstances,

-
-/*
- * Possible future direction of architecture for max performance :
- *
- * We're using a single start array for the NCR chip. This is
- * sub-optimal, because we cannot add a command which would conflict with
- * an executing command to this start queue, and therefore must insert the
- * next command for a given I/T/L combination after the first has completed;
- * incurring our interrupt latency between SCSI commands.
- *
- * To allow further pipelining of the NCR and host CPU operation, we want
- * to set things up so that immediately on termination of a command destined
- * for a given LUN, we get that LUN busy again.
- *
- * To do this, we need to add a 32 bit pointer to which is jumped to
- * on completion of a command. If no new command is available, this
- * would point to the usual DSA issue queue select routine.
- *
- * If one were, it would point to a per-NCR53c7x0_cmd select routine
- * which starts execution immediately, inserting the command at the head
- * of the start queue if the NCR chip is selected or reselected.
- *
- * We would change so that we keep a list of outstanding commands
- * for each unit, rather than a single running_list. We'd insert
- * a new command into the right running list; if the NCR didn't
- * have something running for that yet, we'd put it in the
- * start queue as well. Some magic needs to happen to handle the
- * race condition between the first command terminating before the
- * new one is written.
- *
- * Potential for profiling :
- * Call do_gettimeofday(struct timeval *tv) to get 800ns resolution.
- */
-
-
-/*
- * TODO :
- * 1. To support WIDE transfers, not much needs to happen. We
- * should do CHMOVE instructions instead of MOVEs when
- * we have scatter/gather segments of uneven length. When
- * we do this, we need to handle the case where we disconnect
- * between segments.
- *
- * 2. Currently, when Icky things happen we do a FATAL(). Instead,
- * we want to do an integrity check on the parts of the NCR hostdata
- * structure which were initialized at boot time; FATAL() if that
- * fails, and otherwise try to recover. Keep track of how many
- * times this has happened within a single SCSI command; if it
- * gets excessive, then FATAL().
- *
- * 3. Parity checking is currently disabled, and a few things should
- * happen here now that we support synchronous SCSI transfers :
- * 1. On soft-reset, we shoould set the EPC (Enable Parity Checking)
- * and AAP (Assert SATN/ on parity error) bits in SCNTL0.
- *
- * 2. We should enable the parity interrupt in the SIEN0 register.
- *
- * 3. intr_phase_mismatch() needs to believe that message out is
- * always an "acceptable" phase to have a mismatch in. If
- * the old phase was MSG_IN, we should send a MESSAGE PARITY
- * error. If the old phase was something else, we should send
- * a INITIATOR_DETECTED_ERROR message. Note that this could
- * cause a RESTORE POINTERS message; so we should handle that
- * correctly first. Instead, we should probably do an
- * initiator_abort.
- *
- * 4. MPEE bit of CTEST4 should be set so we get interrupted if
- * we detect an error.
- *
- *
- * 5. The initial code has been tested on the NCR53c810. I don't
- * have access to NCR53c700, 700-66 (Forex boards), NCR53c710
- * (NCR Pentium systems), NCR53c720, NCR53c820, or NCR53c825 boards to
- * finish development on those platforms.
- *
- * NCR53c820/825/720 - need to add wide transfer support, including WDTR
- * negotiation, programming of wide transfer capabilities
- * on reselection and table indirect selection.
- *
- * NCR53c710 - need to add fatal interrupt or GEN code for
- * command completion signaling. Need to modify all
- * SDID, SCID, etc. registers, and table indirect select code
- * since these use bit fielded (ie 1<<target) instead of
- * binary encoded target ids. Need to accommodate
- * different register mappings, probably scan through
- * the SCRIPT code and change the non SFBR register operand
- * of all MOVE instructions.
- *
- * It is rather worse than this actually, the 710 corrupts
- * both TEMP and DSA when you do a MOVE MEMORY. This
- * screws you up all over the place. MOVE MEMORY 4 with a
- * destination of DSA seems to work OK, which helps some.
- * Richard Hirst richard@sleepie.demon.co.uk
- *
- * NCR53c700/700-66 - need to add code to refix addresses on
- * every nexus change, eliminate all table indirect code,
- * very messy.
- *
- * 6. The NCR53c7x0 series is very popular on other platforms that
- * could be running Linux - ie, some high performance AMIGA SCSI
- * boards use it.
- *
- * So, I should include #ifdef'd code so that it is
- * compatible with these systems.
- *
- * Specifically, the little Endian assumptions I made in my
- * bit fields need to change, and if the NCR doesn't see memory
- * the right way, we need to provide options to reverse words
- * when the scripts are relocated.
- *
- * 7. Use vremap() to access memory mapped boards.

-/*
- * Allow for simultaneous existence of multiple SCSI scripts so we
- * can have a single driver binary for all of the family.
- *
- * - one for NCR53c700 and NCR53c700-66 chips (not yet supported)
- * - one for rest (only the NCR53c810, 815, 820, and 825 are currently
- * supported)
- *
- * So that we only need two SCSI scripts, we need to modify things so
- * that we fixup register accesses in READ/WRITE instructions, and
- * we'll also have to accommodate the bit vs. binary encoding of IDs

-; IMPORTANT : This code is self modifying due to the limitations of
-; the NCR53c7,8xx series chips. Persons debugging this code with
-; the remote debugger should take this into account, and NOT set
-; breakpoints in modified instructions.
-;
-; Design:
-; The NCR53c7,8xx family of SCSI chips are busmasters with an onboard
-; microcontroller using a simple instruction set.
-;
-; So, to minimize the effects of interrupt latency, and to maximize
-; throughput, this driver offloads the practical maximum amount
-; of processing to the SCSI chip while still maintaining a common
-; structure.
-;
-; Where tradeoffs were needed between efficiency on the older
-; chips and the newer NCR53c800 series, the NCR53c800 series
-; was chosen.
-;
-; While the NCR53c700 and NCR53c700-66 lacked the facilities to fully
-; automate SCSI transfers without host processor intervention, this
-; isn't the case with the NCR53c710 and newer chips which allow
-;
-; - reads and writes to the internal registers from within the SCSI
-; scripts, allowing the SCSI SCRIPTS(tm) code to save processor
-; state so that multiple threads of execution are possible, and also
-; provide an ALU for loop control, etc.
-;
-; - table indirect addressing for some instructions. This allows
-; pointers to be located relative to the DSA ((Data Structure
-; Address) register.
-;
-; These features make it possible to implement a mailbox style interface,
-; where the same piece of code is run to handle I/O for multiple threads
-; at once minimizing our need to relocate code. Since the NCR53c700/
-; NCR53c800 series have a unique combination of features, making a
-; a standard ingoing/outgoing mailbox system, costly, I've modified it.
-;
-; - Mailboxes are a mixture of code and data. This lets us greatly
-; simplify the NCR53c810 code and do things that would otherwise
-; not be possible.
-;
-; The saved data pointer is now implemented as follows :
-;
-; Control flow has been architected such that if control reaches
-; munge_save_data_pointer, on a restore pointers message or
-; reconnection, a jump to the address formerly in the TEMP register
-; will allow the SCSI command to resume execution.
-;
-
-;
-; Note : the DSA structures must be aligned on 32 bit boundaries,
-; since the source and destination of MOVE MEMORY instructions
-; must share the same alignment and this is the alignment of the
-; NCR registers.
-;
-
-; For some systems (MVME166, for example) dmode is always the same, so don't
-; waste time writing it

-; Once a device has initiated reselection, we need to compare it
-; against the singly linked list of commands which have disconnected
-; and are pending reselection. These commands are maintained in
-; an unordered singly linked list of DSA structures, through the
-; DSA pointers at their 'centers' headed by the reconnect_dsa_head
-; pointer.
-;
-; To avoid complications in removing commands from the list,
-; I minimize the amount of expensive (at eight operations per
-; addition @ 500-600ns each) pointer operations which must
-; be done in the NCR driver by precomputing them on the

-; to remove the command from the list. Similarly, DSA is
-; loaded with the address of the next DSA structure and
-; reselected_check_next is called if a failure occurs.

-; IMPORTANT : This code is self modifying due to the limitations of
-; the NCR53c7,8xx series chips. Persons debugging this code with
-; the remote debugger should take this into account, and NOT set
-; breakpoints in modified instructions.
-;
-; Design:
-; The NCR53c7,8xx family of SCSI chips are busmasters with an onboard
-; microcontroller using a simple instruction set.
-;
-; So, to minimize the effects of interrupt latency, and to maximize
-; throughput, this driver offloads the practical maximum amount
-; of processing to the SCSI chip while still maintaining a common
-; structure.
-;
-; Where tradeoffs were needed between efficiency on the older
-; chips and the newer NCR53c800 series, the NCR53c800 series
-; was chosen.
-;
-; While the NCR53c700 and NCR53c700-66 lacked the facilities to fully
-; automate SCSI transfers without host processor intervention, this
-; isn't the case with the NCR53c710 and newer chips which allow
-;
-; - reads and writes to the internal registers from within the SCSI
-; scripts, allowing the SCSI SCRIPTS(tm) code to save processor
-; state so that multiple threads of execution are possible, and also
-; provide an ALU for loop control, etc.
-;
-; - table indirect addressing for some instructions. This allows
-; pointers to be located relative to the DSA ((Data Structure
-; Address) register.
-;
-; These features make it possible to implement a mailbox style interface,
-; where the same piece of code is run to handle I/O for multiple threads
-; at once minimizing our need to relocate code. Since the NCR53c700/
-; NCR53c800 series have a unique combination of features, making a
-; a standard ingoing/outgoing mailbox system, costly, I've modified it.
-;
-; - Mailboxes are a mixture of code and data. This lets us greatly
-; simplify the NCR53c810 code and do things that would otherwise
-; not be possible.
-;
-; The saved data pointer is now implemented as follows :
-;
-; Control flow has been architected such that if control reaches
-; munge_save_data_pointer, on a restore pointers message or
-; reconnection, a jump to the address formerly in the TEMP register
-; will allow the SCSI command to resume execution.
-;
-
-;
-; Note : the DSA structures must be aligned on 32 bit boundaries,
-; since the source and destination of MOVE MEMORY instructions
-; must share the same alignment and this is the alignment of the
-; NCR registers.
-;
-
-; For some systems (MVME166, for example) dmode is always the same, so don't
-; waste time writing it

-; Once a device has initiated reselection, we need to compare it
-; against the singly linked list of commands which have disconnected
-; and are pending reselection. These commands are maintained in
-; an unordered singly linked list of DSA structures, through the
-; DSA pointers at their 'centers' headed by the reconnect_dsa_head
-; pointer.
-;
-; To avoid complications in removing commands from the list,
-; I minimize the amount of expensive (at eight operations per
-; addition @ 500-600ns each) pointer operations which must
-; be done in the NCR driver by precomputing them on the
-; host processor during dsa structure generation.
-;
-; The fixed-up per DSA code knows how to recognize the nexus
-; associated with the corresponding SCSI command, and modifies
-; the source and destination pointers for the MOVE MEMORY
-; instruction which is executed when reselected_ok is called
-; to remove the command from the list. Similarly, DSA is
-; loaded with the address of the next DSA structure and
-; reselected_check_next is called if a failure occurs.
-;
-; Perhaps more concisely, the net effect of the mess is
-;
-; for (dsa = reconnect_dsa_head, dest = &reconnect_dsa_head,
-; src = NULL; dsa; dest = &dsa->next, dsa = dsa->next) {

-; msg_in
-; munge_msg
-;
-; PURPOSE : process messages from a target. msg_in is called when the
-; caller hasn't read the first byte of the message. munge_message
-; is called when the caller has read the first byte of the message,
-; and left it in SFBR. msg_in_restart is called when the caller
-; hasn't read the first byte of the message, and wishes RETURN
-; to transfer control back to the address of the conditional
-; CALL instruction rather than to the instruction after it.
-;
-; Various int_* interrupts are generated when the host system
-; needs to intervene, as is the case with SDTR, WDTR, and
-; INITIATE RECOVERY messages.
-;
-; When the host system handles one of these interrupts,
-; it can respond by reentering at reject_message,
-; which rejects the message and returns control to
-; the caller of msg_in or munge_msg, accept_message
-; which clears ACK and returns control, or reply_message
-; which sends the message pointed to by the DSA
-; msgout_other table indirect field.
-;
-; DISCONNECT messages are handled by moving the command
-; to the reconnect_dsa_queue.
-
-; NOTE: DSA should be valid when we get here - we cannot save both it
-; and TEMP in this routine.
-
-;
-; INPUTS : DSA - SCSI COMMAND, SFBR - first byte of message (munge_msg
-; only)
-;
-; CALLS : NO. The TEMP register isn't backed up to allow nested calls.
-;
-; MODIFIES : SCRATCH, DSA on DISCONNECT
-;
-; EXITS : On receipt of SAVE DATA POINTER, RESTORE POINTERS,
-; and normal return from message handlers running under
-; Linux, control is returned to the caller. Receipt
-; of DISCONNECT messages pass control to dsa_schedule.
