Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

; 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.

; data_transfer

;
; PURPOSE : handle the main data transfer for a SCSI command in
; several parts. In the first part, data_transfer, DATA_IN
; and DATA_OUT phases are allowed, with the user provided
; code (usually dynamically generated based on the scatter/gather
; list associated with a SCSI command) called to handle these
; phases.
;
; After control has passed to one of the user provided
; DATA_IN or DATA_OUT routines, back calls are made to
; other_transfer_in or other_transfer_out to handle non-DATA IN
; and DATA OUT phases respectively, with the state of the active
; data pointer being preserved in TEMP.
;
; On completion, the user code passes control to other_transfer
; which causes DATA_IN and DATA_OUT to result in unexpected_phase
; interrupts so that data overruns may be trapped.
;
; INPUTS : DSA - SCSI command
;
; CALLS : OK in data_transfer_start, not ok in other_out and other_in, ok in
; other_transfer
;
; MODIFIES : SCRATCH
;
; EXITS : if STATUS IN is detected, signifying command completion,
; the NCR jumps to command_complete. If MSG IN occurs, a
; CALL is made to msg_in. Otherwise, other_transfer runs in
; an infinite loop.

; msg_in_restart

;
; 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.

; PURPOSE : handle command termination when STATUS IN is detected by reading

;
; Normal termination results in an INTFLY instruction, and
; the host system can pick out which command terminated by
; examining the MESSAGE and STATUS buffers of all currently
; executing commands;
;
; Abnormal (CHECK_CONDITION) termination results in an
; int_err_check_condition interrupt so that a REQUEST SENSE
; command can be issued out-of-order so that no other command
; clears the contingent allegiance condition.
;
;
; INPUTS : DSA - command
;
; CALLS : OK
;
; EXITS : On successful termination, control is passed to schedule.
; On abnormal termination, the user will usually modify the

; wait_reselect
;
; PURPOSE : This is essentially the idle routine, where control lands
; when there are no new processes to schedule. wait_reselect
; waits for reselection, selection, and new commands.
;
; When a successful reselection occurs, with the aid
; of fixed up code in each DSA, wait_reselect walks the
; reconnect_dsa_queue, asking each dsa if the target ID
; and LUN match its.
;
; If a match is found, a call is made back to reselected_ok,
; which through the miracles of self modifying code, extracts
; the found DSA from the reconnect_dsa_queue and then
; returns control to the DSAs thread of execution.
;
; INPUTS : NONE
;
; CALLS : OK
;
; MODIFIES : DSA,
;
; EXITS : On successful reselection, control is returned to the
; DSA which called reselected_ok. If the WAIT RESELECT
; was interrupted by a new commands arrival signaled by
; SIG_P, control is passed to schedule. If the NCR is
; selected, the host system is interrupted with an
; int_err_selected which is usually responded to by
; setting DSP to the target_abort address.
