* Make the ahc and ahd probes more alike. * Remove some redundant code. * ahd: Don't initiate negotiation for a discovery xs when the negotiation goal is set. Just looking at the auto_negotiate mask is enough, and it can cause an endless loop if the request gets requeued (happens with a of a PPR negotiation, which ends with a busfree).

Apply the following change from 06/28/2003 04:45:25 by gibbs to the FreeBSD ahd driver:
aic79xx.h: Add softc flag to indicate that we have seen at least one selection since the last bus reset or SE/LVD bus change.
aic79xx.c: Fix a few style nits.
In ahd_update_pending_scbs(), only touch card registers once we have found an SCB that needs to be updated. This removes lots of clutter from PCI traces taken of error recovery performed by the driver.
Short circuit the first selection iocell workaround handler if we've run once since the last bus reset or iocell change. This also removes clutter from PCI traces.
Note if completions are pending in the qoutfifo when we dump card state.

Apply the following change checked in 2003/05/04 00:20:07 by gibbs to the FreeBSD ahd driver:
Correct spelling errors.
Switch to handling bad SCSI status as a sequencer interrupt instead of having the kernel proccess these failures via the completion queue. This is done because:
o The old scheme required us to pause the sequencer and clear critical sections for each SCB. It seems that these pause actions, if coincident with a sequencer FIFO interrupt, would result in a FIFO interrupt getting lost or directing to the wrong FIFO. This caused hangs when the driver was stressed under high "queue full" loads. o The completion code assumed that it was always called with the sequencer running. This may not be the case in timeout processing where completions occur manually via ahd_pause_and_flushwork(). o With this scheme, the extra expense of clearing critical sections is avoided since the sequencer will only self pause once all pending selections have cleared and it is not in a critical section.
aic79xx.c Add code to handle the new BAD_SCB_STATUS sequencer interrupt code. This just redirects the SCB through the already existing ahd_complete_scb() code path. Remove code in ahd_handle_scsi_status() that paused the sequencer, made sure that no selections where pending, and cleared critical sections. Bad status SCBs are now only processed when all of these conditions are true.
aic79xx.reg: Add the BAD_SCB_STATUS sequencer interrupt code.
aic79xx.seq: When completing an SCB upload to the host, if we are doing this because the SCB contains non-zero SCSI status, defer completing the SCB until there are no pending selection events. When completing these SCBs, use the new BAD_SCB_STATUS sequencer interrupt. For all other uploaded SCBs (currently only for underruns), the SCB is completed via the normal done queue. Additionally, keep the SCB that is currently being uploaded on the COMPLETE_DMA_SCB list until the dma is completed, not just until the DMA is started. This ensures that the DMA is restarted properly should the host disable the DMA transfer for some reason.
In our RevA workaround for Maxtor drives, guard against the host pausing us while trying to pause I/O until the first data-valid REQ by clearing the current snapshot so that we can tell if the transfer has completed prior to us noticing the REQINIT status.
In cfg4data_intr, shave off an instruction before getting the data path running by adding an entrypoint to the overrun handler to also increment the FIFO use count.
In the overrun handler, be sure to clear our LONGJMP address in both exit paths.
Perform a few sequencer optimizations.
aic79xx.c: Print the full path from the SCB when a packetized status overrun occurs.
Remove references to LONGJMP_SCB which is being removed from firmware usage.
Print the new SCB_FIFO_USE_COUNT field in the per-SCB section of ahd_dump_card_state(). The SCB_TAG field is now re-used by the sequencer, so it no longer makes sense to reference this field in the kernel driver.
aic79xx.h: Re-arrange fields in the hardware SCB from largest size type to smallest. This makes it easier to move fields without changing field alignment.
The hardware scb tag field is now down near the "spare" portion of the SCB to facilitate reuse by the sequencer.
aic79xx.reg: Remove LONGJMP_ADDR.
Rearrange SCB fields to match aic79xx.h. Add SCB_FIFO_USE_COUNT as the first byte of the SCB_TAG field.
aic79xx.seq: Add a per-SCB "Fifos in use count" field and use it to determine when it is safe (all data posted) to deliver status back to the host. The old method involved polling one or both FIFOs to verify that the current task did not have pending data. This makes running down the GSFIFO very cheap, so we will empty the GSFIFO in one idle loop pass in all cases.
Use this simplification of the completion process to prune down the data FIFO teardown sequencer for packetized transfers. Much more code is now shared between the data residual and transfer complete cases.
Correct some issues in the packetized status handler. It used to be possible to CLRCHN our FIFO before status had fully transferred to the host. We also failed to handle NONPACKREQ phases that could occur should a CRC error occur during transmission of the status data packet.
Correct a few big endian issues:
aic79xx.c: aic79xx_inline.h: aic79xx_pci.c: aic79xx_osm.c: o Always get the SCB's tag via the SCB_GET_TAG acccessor o Add missing use of byte swapping macros when touching hscb fields. o Don't double swap SEEPROM data when it is printed. Correct a big-endian bug. We cannot assign a o When assigning a 32bit LE variable to a 64bit LE variable, we must be explict about how the words of the 64bit LE variable are initialized. Cast to (uint32_t*) to do this.
aic79xx.c: In ahd_clear_critical_section(), hit CRLSCSIINT after restoring the interrupt masks to avoid what appears to be a glitch on SCSIINT. Any real SCSIINT status will be persistent and will immidiately reset SCSIINT. This clear should only get rid of spurious SCSIINTs.
This glitch was the cause of the "Unexpected PKT busfree" status that occurred under high queue full loads
Call ahd_fini_scbdata() after shutdown so that any ahd_chip_init() routine that might access SCB data will not access free'd memory.
Reset the bus on an IOERR since the chip doesn't seem to reset to the new voltage level without this. Change offset calculation for scatter gather maps so that the calculation is correct if an integral multiple of sg lists does not fit in the allocation size.
Adjust bus dma tag for data buffers based on 39BIT addressing flag in our softc.
Use the QFREEZE count to simplify ahd_pause_and_flushworkd(). We can thus rely on the sequencer eventually clearing ENSELO.
In ahd_abort_scbs(), fix a bug that could potentially corrupt sequencer state. The saved SCB was being restored in the SCSI mode instead of the saved mode. It turns out that the SCB did not need to be saved at all as the scbptr is already restored by all subroutines called during this function that modify that register.
aic79xx.c: aic79xx.h: aic79xx_pci.c: Add support for parsing the seeprom vital product data. The VPD data are currently unused.
aic79xx.h: aic79xx.seq: aic79xx_pci.c: Add a firmware workaround to make the LED blink brighter during packetized operations on the H2A.
aic79xx_inline.h: The host does not use timer interrupts, so don't gate our decision on whether or not to unpause the sequencer on whether or not a timer interrupt is pending.

Make this work on systems where bus_dmamap_sync() is not a noop. In particular, when doing the "swap hscbs" trick, the scb must reference the correct hscb_map when it gets a new hscb, otherwise when you go to sync an hscb later, you could end up using the wrong dmamap.
In order to make this work, we have to convert the shared_data stuff to use a map_node, because of the "sentinel" trick played with the initial "next_hscb".
This driver now works on XScale-based platforms.

* Make the ahc and ahd probes more alike. * Remove some redundant code. * ahd: Don't initiate negotiation for a discovery xs when the negotiation goal is set. Just looking at the auto_negotiate mask is enough, and it can cause an endless loop if the request gets requeued (happens with a of a PPR negotiation, which ends with a busfree).

Apply the following change from 06/28/2003 04:45:25 by gibbs to the FreeBSD ahd driver:
aic79xx.h: Add softc flag to indicate that we have seen at least one selection since the last bus reset or SE/LVD bus change.
aic79xx.c: Fix a few style nits.
In ahd_update_pending_scbs(), only touch card registers once we have found an SCB that needs to be updated. This removes lots of clutter from PCI traces taken of error recovery performed by the driver.
Short circuit the first selection iocell workaround handler if we've run once since the last bus reset or iocell change. This also removes clutter from PCI traces.
Note if completions are pending in the qoutfifo when we dump card state.

Apply the following change checked in 2003/05/04 00:20:07 by gibbs to the FreeBSD ahd driver:
Correct spelling errors.
Switch to handling bad SCSI status as a sequencer interrupt instead of having the kernel proccess these failures via the completion queue. This is done because:
o The old scheme required us to pause the sequencer and clear critical sections for each SCB. It seems that these pause actions, if coincident with a sequencer FIFO interrupt, would result in a FIFO interrupt getting lost or directing to the wrong FIFO. This caused hangs when the driver was stressed under high "queue full" loads. o The completion code assumed that it was always called with the sequencer running. This may not be the case in timeout processing where completions occur manually via ahd_pause_and_flushwork(). o With this scheme, the extra expense of clearing critical sections is avoided since the sequencer will only self pause once all pending selections have cleared and it is not in a critical section.
aic79xx.c Add code to handle the new BAD_SCB_STATUS sequencer interrupt code. This just redirects the SCB through the already existing ahd_complete_scb() code path. Remove code in ahd_handle_scsi_status() that paused the sequencer, made sure that no selections where pending, and cleared critical sections. Bad status SCBs are now only processed when all of these conditions are true.
aic79xx.reg: Add the BAD_SCB_STATUS sequencer interrupt code.
aic79xx.seq: When completing an SCB upload to the host, if we are doing this because the SCB contains non-zero SCSI status, defer completing the SCB until there are no pending selection events. When completing these SCBs, use the new BAD_SCB_STATUS sequencer interrupt. For all other uploaded SCBs (currently only for underruns), the SCB is completed via the normal done queue. Additionally, keep the SCB that is currently being uploaded on the COMPLETE_DMA_SCB list until the dma is completed, not just until the DMA is started. This ensures that the DMA is restarted properly should the host disable the DMA transfer for some reason.
In our RevA workaround for Maxtor drives, guard against the host pausing us while trying to pause I/O until the first data-valid REQ by clearing the current snapshot so that we can tell if the transfer has completed prior to us noticing the REQINIT status.
In cfg4data_intr, shave off an instruction before getting the data path running by adding an entrypoint to the overrun handler to also increment the FIFO use count.
In the overrun handler, be sure to clear our LONGJMP address in both exit paths.
Perform a few sequencer optimizations.
aic79xx.c: Print the full path from the SCB when a packetized status overrun occurs.
Remove references to LONGJMP_SCB which is being removed from firmware usage.
Print the new SCB_FIFO_USE_COUNT field in the per-SCB section of ahd_dump_card_state(). The SCB_TAG field is now re-used by the sequencer, so it no longer makes sense to reference this field in the kernel driver.
aic79xx.h: Re-arrange fields in the hardware SCB from largest size type to smallest. This makes it easier to move fields without changing field alignment.
The hardware scb tag field is now down near the "spare" portion of the SCB to facilitate reuse by the sequencer.
aic79xx.reg: Remove LONGJMP_ADDR.
Rearrange SCB fields to match aic79xx.h. Add SCB_FIFO_USE_COUNT as the first byte of the SCB_TAG field.
aic79xx.seq: Add a per-SCB "Fifos in use count" field and use it to determine when it is safe (all data posted) to deliver status back to the host. The old method involved polling one or both FIFOs to verify that the current task did not have pending data. This makes running down the GSFIFO very cheap, so we will empty the GSFIFO in one idle loop pass in all cases.
Use this simplification of the completion process to prune down the data FIFO teardown sequencer for packetized transfers. Much more code is now shared between the data residual and transfer complete cases.
Correct some issues in the packetized status handler. It used to be possible to CLRCHN our FIFO before status had fully transferred to the host. We also failed to handle NONPACKREQ phases that could occur should a CRC error occur during transmission of the status data packet.
Correct a few big endian issues:
aic79xx.c: aic79xx_inline.h: aic79xx_pci.c: aic79xx_osm.c: o Always get the SCB's tag via the SCB_GET_TAG acccessor o Add missing use of byte swapping macros when touching hscb fields. o Don't double swap SEEPROM data when it is printed. Correct a big-endian bug. We cannot assign a o When assigning a 32bit LE variable to a 64bit LE variable, we must be explict about how the words of the 64bit LE variable are initialized. Cast to (uint32_t*) to do this.
aic79xx.c: In ahd_clear_critical_section(), hit CRLSCSIINT after restoring the interrupt masks to avoid what appears to be a glitch on SCSIINT. Any real SCSIINT status will be persistent and will immidiately reset SCSIINT. This clear should only get rid of spurious SCSIINTs.
This glitch was the cause of the "Unexpected PKT busfree" status that occurred under high queue full loads
Call ahd_fini_scbdata() after shutdown so that any ahd_chip_init() routine that might access SCB data will not access free'd memory.
Reset the bus on an IOERR since the chip doesn't seem to reset to the new voltage level without this. Change offset calculation for scatter gather maps so that the calculation is correct if an integral multiple of sg lists does not fit in the allocation size.
Adjust bus dma tag for data buffers based on 39BIT addressing flag in our softc.
Use the QFREEZE count to simplify ahd_pause_and_flushworkd(). We can thus rely on the sequencer eventually clearing ENSELO.
In ahd_abort_scbs(), fix a bug that could potentially corrupt sequencer state. The saved SCB was being restored in the SCSI mode instead of the saved mode. It turns out that the SCB did not need to be saved at all as the scbptr is already restored by all subroutines called during this function that modify that register.
aic79xx.c: aic79xx.h: aic79xx_pci.c: Add support for parsing the seeprom vital product data. The VPD data are currently unused.
aic79xx.h: aic79xx.seq: aic79xx_pci.c: Add a firmware workaround to make the LED blink brighter during packetized operations on the H2A.
aic79xx_inline.h: The host does not use timer interrupts, so don't gate our decision on whether or not to unpause the sequencer on whether or not a timer interrupt is pending.

Make this work on systems where bus_dmamap_sync() is not a noop. In particular, when doing the "swap hscbs" trick, the scb must reference the correct hscb_map when it gets a new hscb, otherwise when you go to sync an hscb later, you could end up using the wrong dmamap.
In order to make this work, we have to convert the shared_data stuff to use a map_node, because of the "sentinel" trick played with the initial "next_hscb".
This driver now works on XScale-based platforms.

* Make the ahc and ahd probes more alike. * Remove some redundant code. * ahd: Don't initiate negotiation for a discovery xs when the negotiation goal is set. Just looking at the auto_negotiate mask is enough, and it can cause an endless loop if the request gets requeued (happens with a of a PPR negotiation, which ends with a busfree).

Apply the following change from 06/28/2003 04:45:25 by gibbs to the FreeBSD ahd driver:
aic79xx.h: Add softc flag to indicate that we have seen at least one selection since the last bus reset or SE/LVD bus change.
aic79xx.c: Fix a few style nits.
In ahd_update_pending_scbs(), only touch card registers once we have found an SCB that needs to be updated. This removes lots of clutter from PCI traces taken of error recovery performed by the driver.
Short circuit the first selection iocell workaround handler if we've run once since the last bus reset or iocell change. This also removes clutter from PCI traces.
Note if completions are pending in the qoutfifo when we dump card state.

Apply the following change checked in 2003/05/04 00:20:07 by gibbs to the FreeBSD ahd driver:
Correct spelling errors.
Switch to handling bad SCSI status as a sequencer interrupt instead of having the kernel proccess these failures via the completion queue. This is done because:
o The old scheme required us to pause the sequencer and clear critical sections for each SCB. It seems that these pause actions, if coincident with a sequencer FIFO interrupt, would result in a FIFO interrupt getting lost or directing to the wrong FIFO. This caused hangs when the driver was stressed under high "queue full" loads. o The completion code assumed that it was always called with the sequencer running. This may not be the case in timeout processing where completions occur manually via ahd_pause_and_flushwork(). o With this scheme, the extra expense of clearing critical sections is avoided since the sequencer will only self pause once all pending selections have cleared and it is not in a critical section.
aic79xx.c Add code to handle the new BAD_SCB_STATUS sequencer interrupt code. This just redirects the SCB through the already existing ahd_complete_scb() code path. Remove code in ahd_handle_scsi_status() that paused the sequencer, made sure that no selections where pending, and cleared critical sections. Bad status SCBs are now only processed when all of these conditions are true.
aic79xx.reg: Add the BAD_SCB_STATUS sequencer interrupt code.
aic79xx.seq: When completing an SCB upload to the host, if we are doing this because the SCB contains non-zero SCSI status, defer completing the SCB until there are no pending selection events. When completing these SCBs, use the new BAD_SCB_STATUS sequencer interrupt. For all other uploaded SCBs (currently only for underruns), the SCB is completed via the normal done queue. Additionally, keep the SCB that is currently being uploaded on the COMPLETE_DMA_SCB list until the dma is completed, not just until the DMA is started. This ensures that the DMA is restarted properly should the host disable the DMA transfer for some reason.
In our RevA workaround for Maxtor drives, guard against the host pausing us while trying to pause I/O until the first data-valid REQ by clearing the current snapshot so that we can tell if the transfer has completed prior to us noticing the REQINIT status.
In cfg4data_intr, shave off an instruction before getting the data path running by adding an entrypoint to the overrun handler to also increment the FIFO use count.
In the overrun handler, be sure to clear our LONGJMP address in both exit paths.
Perform a few sequencer optimizations.
aic79xx.c: Print the full path from the SCB when a packetized status overrun occurs.
Remove references to LONGJMP_SCB which is being removed from firmware usage.
Print the new SCB_FIFO_USE_COUNT field in the per-SCB section of ahd_dump_card_state(). The SCB_TAG field is now re-used by the sequencer, so it no longer makes sense to reference this field in the kernel driver.
aic79xx.h: Re-arrange fields in the hardware SCB from largest size type to smallest. This makes it easier to move fields without changing field alignment.
The hardware scb tag field is now down near the "spare" portion of the SCB to facilitate reuse by the sequencer.
aic79xx.reg: Remove LONGJMP_ADDR.
Rearrange SCB fields to match aic79xx.h. Add SCB_FIFO_USE_COUNT as the first byte of the SCB_TAG field.
aic79xx.seq: Add a per-SCB "Fifos in use count" field and use it to determine when it is safe (all data posted) to deliver status back to the host. The old method involved polling one or both FIFOs to verify that the current task did not have pending data. This makes running down the GSFIFO very cheap, so we will empty the GSFIFO in one idle loop pass in all cases.
Use this simplification of the completion process to prune down the data FIFO teardown sequencer for packetized transfers. Much more code is now shared between the data residual and transfer complete cases.
Correct some issues in the packetized status handler. It used to be possible to CLRCHN our FIFO before status had fully transferred to the host. We also failed to handle NONPACKREQ phases that could occur should a CRC error occur during transmission of the status data packet.
Correct a few big endian issues:
aic79xx.c: aic79xx_inline.h: aic79xx_pci.c: aic79xx_osm.c: o Always get the SCB's tag via the SCB_GET_TAG acccessor o Add missing use of byte swapping macros when touching hscb fields. o Don't double swap SEEPROM data when it is printed. Correct a big-endian bug. We cannot assign a o When assigning a 32bit LE variable to a 64bit LE variable, we must be explict about how the words of the 64bit LE variable are initialized. Cast to (uint32_t*) to do this.
aic79xx.c: In ahd_clear_critical_section(), hit CRLSCSIINT after restoring the interrupt masks to avoid what appears to be a glitch on SCSIINT. Any real SCSIINT status will be persistent and will immidiately reset SCSIINT. This clear should only get rid of spurious SCSIINTs.
This glitch was the cause of the "Unexpected PKT busfree" status that occurred under high queue full loads
Call ahd_fini_scbdata() after shutdown so that any ahd_chip_init() routine that might access SCB data will not access free'd memory.
Reset the bus on an IOERR since the chip doesn't seem to reset to the new voltage level without this. Change offset calculation for scatter gather maps so that the calculation is correct if an integral multiple of sg lists does not fit in the allocation size.
Adjust bus dma tag for data buffers based on 39BIT addressing flag in our softc.
Use the QFREEZE count to simplify ahd_pause_and_flushworkd(). We can thus rely on the sequencer eventually clearing ENSELO.
In ahd_abort_scbs(), fix a bug that could potentially corrupt sequencer state. The saved SCB was being restored in the SCSI mode instead of the saved mode. It turns out that the SCB did not need to be saved at all as the scbptr is already restored by all subroutines called during this function that modify that register.
aic79xx.c: aic79xx.h: aic79xx_pci.c: Add support for parsing the seeprom vital product data. The VPD data are currently unused.
aic79xx.h: aic79xx.seq: aic79xx_pci.c: Add a firmware workaround to make the LED blink brighter during packetized operations on the H2A.
aic79xx_inline.h: The host does not use timer interrupts, so don't gate our decision on whether or not to unpause the sequencer on whether or not a timer interrupt is pending.

Make this work on systems where bus_dmamap_sync() is not a noop. In particular, when doing the "swap hscbs" trick, the scb must reference the correct hscb_map when it gets a new hscb, otherwise when you go to sync an hscb later, you could end up using the wrong dmamap.
In order to make this work, we have to convert the shared_data stuff to use a map_node, because of the "sentinel" trick played with the initial "next_hscb".
This driver now works on XScale-based platforms.

ahd, driver for Adaptec 790x U320 controllers. Originally by Justin Gibbs for FreeBSD, ported to NetBSD by Pascal Renauld, Network Storage Solutions, Inc, plus a bunch of changes by me.
This driver is as yet untested in this final form, it will be added to config files when it has been tested.
