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 + + + + + + + + + + + +ABSOLUTE dsa_temp_lun = 0 ; Patch to lun for current dsa +ABSOLUTE dsa_temp_next = 0 ; Patch to dsa next for current dsa +ABSOLUTE dsa_temp_addr_next = 0 ; Patch to address of dsa next address + ; for current dsa +ABSOLUTE dsa_temp_sync = 0 ; Patch to address of per-target + ; sync routine +ABSOLUTE dsa_sscf_710 = 0 ; Patch to address of per-target + ; sscf value (53c710) +ABSOLUTE dsa_temp_target = 0 ; Patch to id for current dsa +ABSOLUTE dsa_temp_addr_saved_pointer = 0; Patch to address of per-command + ; saved data pointer +ABSOLUTE dsa_temp_addr_residual = 0 ; Patch to address of per-command + ; current residual code +ABSOLUTE dsa_temp_addr_saved_residual = 0; Patch to address of per-command + ; saved residual code +ABSOLUTE dsa_temp_addr_new_value = 0 ; Address of value for JUMP operand +ABSOLUTE dsa_temp_addr_array_value = 0 ; Address to copy to +ABSOLUTE dsa_temp_addr_dsa_value = 0 ; Address of this DSA value + +; +; 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.
