; 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.
;
; 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) {

;       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

;
; EXITS : if STATUS IN is detected, signifying command completion,
;       the NCR jumps to command_complete.  If MSG IN occurs, a

;

; EXITS : On successful termination, control is passed to schedule.
;       On abnormal termination, the user will usually modify the

; 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.
