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.
