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

|
|
; 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.
