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 | ||

140 | ; an unordered singly linked list of DSA structures, through the | ||
141 | ; DSA pointers at their 'centers' headed by the reconnect_dsa_head | ||
142 | ; pointer. | ||
143 | ; | ||
144 | ; To avoid complications in removing commands from the list, | ||
145 | ; I minimize the amount of expensive (at eight operations per | ||
146 | ; addition @ 500-600ns each) pointer operations which must | ||
147 | ; be done in the NCR driver by precomputing them on the | ||

153 | ; instruction which is executed when reselected_ok is called | ||
154 | ; to remove the command from the list. Similarly, DSA is | ||
155 | ; loaded with the address of the next DSA structure and | ||
156 | ; reselected_check_next is called if a failure occurs. | ||
