Log:
aic7xxx.c:
Correct an off by one in our critical section handling.
SEQADDR always reads the next instruction to execute,
so we must subtract one from its value before making
comparisons with entries in the critical section table.
Print a few additional registers whenever we dump
card state.
Show the SCB_CONTROL and SCB_TAG values for all pending
SCBs in card SCB ram when dumping card state.
aic7xxx.seq:
Fix a bug introduced while optimizing the SDPTR path.
We would ack the SDPTR message twice on Ultra2 or better
chips if it occurred after all data had been transferred
for a transaction.
Change our workaround for the PCI2.1 retry bug on some
chips. Although the previous workaround was logically
correct, its faster method of draining the FIFO seemed
to occassionally confuse the FIFO state. We now drain
the FIFO at half the speed which avoids the problem.
aic7xxx_pci.c:
Chips with the PCI 2.1 retry bug can't handle a 16byte
cachesize. If the cachesize is set to 16bytes, drop
it to 0.
