| H A D | aic79xx.c | diff 104023 Thu Sep 26 20:54:00 MDT 2002 gibbs Upgrade to version 1.1 of the aic79xx U320 driver. aic79xx.c: o Remove redundant ahd_update_modes() call. o Correct panic in diagnostic should state corruption cause the SCB Id to be invalid during a selection timeout. o Add workaround for missing BUSFREEREV feature in Rev A silicon. o Corect formatting nits. o Use register pretty printing in more places. o Save and restore our SCB pointer when updating the waiting queue list for an "expected" LQ-out busfree. o In ahd_clear_intstat, deal with the missing autoclear in the CLRLQO* registers. o BE fixup in a diagnostic printf. o Make sure that we are in the proper mode before disabling selections in ahd_update_pending_scbs. o Add more diagnostics. o task_attribute_nonpkt_tag -> task_attribute: we don't need a nonpkt_tag field anymore for allowing all 512 SCBs to be used in non-packetized connections. o Negotiate HOLD_MCS to U320 devices. o Add a few additional mode assertions. o Restore the chip mode after clearing out the qinfifo so that code using ahd_abort_scbs sees a consistent mode. o Simplify the DMA engine shutdown routine prior to performing a bus reset. o Perform the sequencer restart after a chip reset prior to setting up our timer to poll for the reset to be complete. On some OSes, the timer could actually pre-empt us and order is important here. o Have our "reset poller" set the expected mode since there is no guarantee of what mode will be in force when we are called from the OS timer. o Save and restore the SCB pointer in ahd_dump_card_state(). This routine must not modify card state. o Ditto for ahd_dump_scbs(). aic79xx.h: o Add a few more chip bug definitions. o Align our tag on a 32bit boundary. aic79xx.reg: aic79xx.seq: o Start work on removing workarounds for Rev B. o Use a special location in scratch from for stroring our SCBPTR during legacy FIFO allocations. This corrects problems in mixed packetized/non-packetized configurations where calling into a FIFO task corrupted our SCBPTR. o Don't rely on DMA priority to guarantee that all data in our FIFOs will flush prior to a command completion notification going out of the command channel. We've never seen this assumption fail, but better safe than sorry. o Deal with missing BUSFREEREV feature in H2A. o Simplify disconnect list code now that the list will always have only a single entry. o Implement the AHD_REG_SLOW_SETTLE_BUG workaround. o Swith to using "REG_ISR" for local mode scratch during our ISR. o Add a missing jmp to the data_group_dma_loop after our data pointers have been re-initialized by the kernel. o Correct test in the bitbucket code so that we actually wait for the bitbucket to complete before signaling the kernel of the overrun condition. o Reposition pkt_saveptrs to avoid a jmp instruction. o Update a comment to reflect that the code now waits for a FIFO to drain prior to issuing a CLRCHN. aic79xx_inline.h: o Remove unused untagged queue handling code. o Don't attempt to htole64 what could be a 32bit value. aic79xx_pci.c: o Set additional bug flags for rev A chips. |
