aic7xxx.c:
Style nits. Make sure that our selection hardware is disabled as soon as possible after detecting a busfree and even go so far as to disable the selection hardware in advance of an event that will cause a busfree (ABORT or BUS DEVICE RESET message). The concern is that the selection hardware will select a target for which, after processing the bus free, there will be no commands pending. The sequencer idle loop will re-enable the selection should it still be necessary. In ahc_handle_scsiint(), clear SSTAT0 events several PCI transactions (most notably reads) prior to clearing SCSIINT. The newer chips seem to take a bit of time to see the change which can make the clearing of SCSIINT ineffective. Don't bother panicing at the end of ahc_handle_scsiint(). Getting to the final else just means we lost the race with clearing SCSIINT. In ahc_free(), handle init-level 0. This can happen when we fail the attach for RAID devices. While I'm here, also kill the parent dma tag. In ahc_match_scb(), consider initiator ccbs to be any that are not from the target mode group. This fixes a bug where an external target reset CCB was not getting cleaned up by the reset code. Don't bother freezing a ccb in any of our "abort" routines when the status is set to CAM_REQ_CMP. This can happen for a target reset ccb. aic7xxx.reg: Reserve space for a completion queue. This will be used to enhance performance in the near future. aic7xxx.seq: Remove an optimization for the 7890 autoflush bug that turned out to allow, in rare cases, some data to get lost. Implement a simpler, faster, fix for the PCI_2_1 retry bug that hangs the sequencer on an SCB dma for certain chips. Test against SAVED_SCSIID rather than SELID during target reselections. This is how we always did it in the past, but the code was modified while trying to work around an issue with the 7895. SAVED_SCSIID takes into account twin channel adapters such as the 2742T, whereas SELID does not have the channel bit. This caused invalid selection warnings and other strangeness on these cards. aic7xxx_pci.c Use the correct mask for checking the generic aic7892 entry.
