- ; 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.

- ; 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.

- ; 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.

- ; The NCR chips cannot do a move memory instruction with the DSA register
- ; as the source or destination. So, we provide a couple of subroutines
- ; that let us switch between the DSA register and scratch register.
- ;
- ; Memory moves to/from the DSPS register also don't work, but we
- ; don't use them.
