Allow 500us between pauses in ahd_pause_and_flushwork(). The maximum we will wait is now 500ms. In the same routine, remove any attempt to clear ENSELO. Let the firmware do it once the current selection has completed. This avoids some race conditions having to do with non-packetized completions and the auto-clearing of ENSELO on packetized completions. Also avoid attempts to clear critical sections when interrups are pending. We are going to loop again anyway, so clearing critical sections is a waste of time. It also may not be possible to clear a critical section if the source of the interrupt was a SEQINT. aic79xx_pci.c: Use the Generic 9005 mask when looking for generic 7901B parts. This allows the driver to attach to 7901B parts on motherboards using a non-Adaptec subvendor ID. aic79xx_inline.h: Test for the SCBRAM_RD_BUG against the bugs field, not the flags field in the softc. aic79xx.c: Cancel pending transactions on devices that respond with a selection timeout. This decreases the duration of timeout recovery when a device disappears. aic79xx.c: Don't bother forcing renegotiation on a selection timeout now that we use the device reset handler to abort any pending commands on the target. The device reset handler already takes us down to async narrow and forces a renegotiation. In the device reset handlers, only send a BDR sent async event if the status is not CAM_SEL_TIMEOUT. This avoids sending this event in the selection timeout case aic79xx.c: Modify the Core timeout handler to verify that another command has the potential to timeout before passing off a command timeout as due to some other command. This safety measure is added in response to a timeout recovery failure on H2B where it appears that incoming reselection status was lost during a drive pull test. In that case, the recovery handler continued to wait for the command that was active on the bus indefinetly. While the root cause of the above issue is still being determined seems a prudent safeguard. aic79xx_pci.c: Add a specific probe entry for the Dell OEM 39320(B). aic79xx.c: aic79xx.h: aic79xx.reg: aic79xx.seq: Modify the aic79xx firmware to never cross a cacheline or ADB boundary when DMA'ing completion entries to the host. In PCI mode, at least in 32/33 configurations, the SCB DMA engine may lose its place in the data-stream should the target force a retry on something other than an 8byte aligned boundary. In PCI-X mode, we do this to avoid split transactions since many chipsets seem to be unable to format proper split completions to continue the data transfer. The above change allows us to drop our completion entries from 8 bytes to 4. We were using 8 byte entries to ensure that PCI retries could only occur on an 8byte aligned boundary. Now that the sequencer guarantees this by splitting up completions, we can safely drop the size to 4 bytes (2 byte tag, one byte SG_RESID, one byte pad). Both the split-completion and PCI retry problems only show up under high tag load when interrupt coalescing is being especially effective. The switch from a 2byte completion entry to an 8 byte entry to solve the PCI problem increased the chance of incurring a split in PCI-X mode when multiple transactions were completed at once. Dropping the completion size to 4 bytes also means that we can complete more commands in a single DMA (128byte FIFO -> 32 commands instead of 16). aic79xx.c: Modify the SCSIINT handler to defer clearing sequencer critical sections to the individual interrupt handlers. This allows us to immediately disable any outgoing selections in the case of an unexpected busfree so we don't inadvertantly clear ENSELO *after* a new selection has started. Doing so may cause the sequencer to miss a successful selection. In ahd_update_pending_scbs(), only clear ENSELO if the bus is currently busy and a selection is not already in progress or the sequencer has yet to handle a pending selection. While we want to ensure that the selection for the SCB at the head of the selection queue is restarted so that any change in negotiation request can take effect, we can't clobber pending selection state without confusing the sequencer into missing a selection.
