| H A D | aicasm.c | diff 13177 Wed Jan 03 06:25:32 MST 1996 gibbs The long awaited stability patch set for the aic7xxx driver: 1) Use cpp to preprocess the sequencer code. 2) Convert all "magic numbers" to #defines shared by the sequencer and kernel driver via the aic7xxx_reg.h file. (The assembler still needs to be re-written in lex/yacc to allow ~|& type constructions). 3) Raise ATN on parity errors for "in" phases and send an initiator detected error or message-in parity error message as appropriate. 4) Turn off the reselection hardware from the time or a (re)connection to busfree. It seems that some fast targets were able to reconnect before the sequencer was able to see busfree. 5) The message buffer is considered "in-use" when there is a positive length count. The ACTIVE_MSG flag was unnecesary. 6) Properly set SCB_NEXT_WAITING to SCB_LIST_HEAD in scbs being added to the waiting scb list. This is a change in how the list code works to facilitate some planned work in the reset code. 7) The fields in the SCB have be re-arranged to be quad-word aligned. 8) The inb code has been rewritten to catch phasemisses and be more efficient. 9) Go back to "snooping the bus" to determine if the incomming identify message will be followed by a simple queue message. Its much faster than doing a search through the SCBs. 10) Implement better tag range checking for incomming tags. 11) Make sdtr_to_rate more accurate (use 25 instead of 24 in calculations - must have been asleep that night). 12) Rearrange some routines to reduce code complexity and size. 13) Update comments and formatting. 14) Fixed bugs I've forgotten about??
