| 48 | ; IMPORTANT : This code is self modifying due to the limitations of |
| 49 | ; the NCR53c7,8xx series chips. Persons debugging this code with |
| 50 | ; the remote debugger should take this into account, and NOT set |
| 51 | ; breakpoints in modified instructions. |
| 52 | ; |
| 53 | ; Design: |
| 54 | ; The NCR53c7,8xx family of SCSI chips are busmasters with an onboard |
| 55 | ; microcontroller using a simple instruction set. |
| 56 | ; |
| 57 | ; So, to minimize the effects of interrupt latency, and to maximize |
| 58 | ; throughput, this driver offloads the practical maximum amount |
| 59 | ; of processing to the SCSI chip while still maintaining a common |
| 60 | ; structure. |
| 61 | ; |
| 62 | ; Where tradeoffs were needed between efficiency on the older |
| 63 | ; chips and the newer NCR53c800 series, the NCR53c800 series |
| 64 | ; was chosen. |
| 65 | ; |
| 66 | ; While the NCR53c700 and NCR53c700-66 lacked the facilities to fully |
| 67 | ; automate SCSI transfers without host processor intervention, this |
| 68 | ; isn't the case with the NCR53c710 and newer chips which allow |
| 69 | ; |
| 70 | ; - reads and writes to the internal registers from within the SCSI |
| 71 | ; scripts, allowing the SCSI SCRIPTS(tm) code to save processor |
| 72 | ; state so that multiple threads of execution are possible, and also |
| 73 | ; provide an ALU for loop control, etc. |
| 74 | ; |
| 75 | ; - table indirect addressing for some instructions. This allows |
| 76 | ; pointers to be located relative to the DSA ((Data Structure |
| 77 | ; Address) register. |
| 78 | ; |
| 79 | ; These features make it possible to implement a mailbox style interface, |
| 80 | ; where the same piece of code is run to handle I/O for multiple threads |
| 81 | ; at once minimizing our need to relocate code. Since the NCR53c700/ |
| 82 | ; NCR53c800 series have a unique combination of features, making a |
| 83 | ; a standard ingoing/outgoing mailbox system, costly, I've modified it. |
| 84 | ; |
| 85 | ; - Mailboxes are a mixture of code and data. This lets us greatly |
| 86 | ; simplify the NCR53c810 code and do things that would otherwise |
| 87 | ; not be possible. |
| 88 | ; |
| 89 | ; The saved data pointer is now implemented as follows : |
| 90 | ; |
| 91 | ; Control flow has been architected such that if control reaches |
| 92 | ; munge_save_data_pointer, on a restore pointers message or |
| 93 | ; reconnection, a jump to the address formerly in the TEMP register |
| 94 | ; will allow the SCSI command to resume execution. |
| 95 | ; |
| 96 | |
| 97 | ; |
| 98 | ; Note : the DSA structures must be aligned on 32 bit boundaries, |
| 99 | ; since the source and destination of MOVE MEMORY instructions |
| 100 | ; must share the same alignment and this is the alignment of the |
| 101 | ; NCR registers. |
| 102 | ; |
| 103 | |
| 104 | ; For some systems (MVME166, for example) dmode is always the same, so don't |
| 105 | ; waste time writing it |

| 141 | ; DSA pointers at their 'centers' headed by the reconnect_dsa_head |

| 143 | ; |
| 144 | ; To avoid complications in removing commands from the list, |

| 1134 | ; is called when the caller has read the first byte of the message, |
| 1135 | ; and left it in SFBR. msg_in_restart is called when the caller |
| 1136 | ; hasn't read the first byte of the message, and wishes RETURN |
| 1137 | ; to transfer control back to the address of the conditional |
| 1138 | ; CALL instruction rather than to the instruction after it. |
