* [SCSI] be2iscsi: Fix for case where task->sc was cleanedup earlierJayamohan Kallickal2011-10-161-0/+5
| | | | | | | | | | | This patch fixes a bug where the task->sc was cleaned up earlier on a different thread, possibly abort, and the completion comes later.

* [SCSI] be2iscsi: Fix for kdump failureJayamohan Kallickal2011-10-163-1/+22
| | | | | | | | | | | | | | This patch fixes the Kdump failure reported by Redhat wich was caused by be2iscsi resetting the Chip when be2iscsi detects it is in crashdump mode. If be2net was loaded before be2iscsi then this leaves be2net driver hanging on to resources that the chip stopped recognising after the reset. This patch replaces chip reset with Function reset so that only the particular function and not the whole chip is affected Signed-off-by: Jayamohan Kallickal <jayamohan.kallickal@emulex.com> Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
* [SCSI] qlogicpti: fix timeoutMeelis Roos2011-10-161-1/+1
| | | | | | | | | | | | | qlogicpti times out for some tape library operations (like mtx inventory). It seems SCSI command timeout is hardcoded into the driver. Fix it by propagating the timeout from scsi request to the controller as suggested by James Bottomley. Tested on Sun Ultra 1 with Sun StorEdge L8 Autoloader.

| | | | | | | | | | This patch adds one more check-condition for scsi_dh_alua handler. Without this, the handler attach fails sometimes during the discovery.

* [SCSI] ipr: Add support to flash FPGA and flash back DRAM imagesWayne Boyer2011-10-162-9/+3Star
| | | | | | | | | | | | | | | The write buffer command is used to download and burn new IOA FW images. The same interface can now be used to flash FPGA and flash back DRAM images. To download and flash the new images takes more than 15 minutes, so increase the write buffer command timeout to 30 minutes. The FPGA and flash back DRAM images don't have the same card_type as the IOA FW image. So, remove the sanity checking from the driver. The adapter has sanity checking and will only accept a valid image.

* [SCSI] libsas: fix port->dev_list lockingDan Williams2011-10-163-12/+18
| | | | | | | | | | | | | | | | | | | | port->dev_list maintains a list of devices attached to a given sas root port. It needs to be mutated under a lock as contexts outside of the single-threaded-libsas-workqueue access the list via sas_find_dev_by_rphy(). Fixup locations where the list was being mutated without a lock. This is a follow-up to commit 5911e963 "[SCSI] libsas: remove expander from dev list on error", where Luben noted [1]: > 2/ We have unlocked list manipulations in sas_ex_discover_end_dev(), > sas_unregister_common_dev(), and sas_ex_discover_end_dev() Yes, I can see that and that is very unfortunate.

* [SCSI] isci: atapi supportDan Williams2011-10-026-16/+380
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on original implementation from Jiangbi Liu and Maciej Trela. ATAPI transfers happen in two-to-three stages. The two stage atapi commands are those that include a dma data transfer. The data transfer portion of these operations is handled by the hardware packet-dma acceleration. The three-stage commands do not have a data transfer and are handled without hardware assistance in raw frame mode. stage1: transmit host-to-device fis to notify the device of an incoming atapi cdb. Upon reception of the pio-setup-fis repost the task_context to perform the dma transfer of the cdb+data (go to stage3), or repost the task_context to transmit the cdb as a raw frame (go to stage 2). stage2: wait for hardware notification of the cdb transmission and then go to stage 3. stage3: wait for the arrival of the terminating device-to-host fis and terminate the command. To keep the implementation simple we only support ATAPI packet-dma protocol (for commands with data) to avoid needing to handle the data transfer manually (like we do for SATA-PIO). This may affect compatibility for a small number of devices (see ATA_HORKAGE_ATAPI_MOD16_DMA). If the data-transfer underruns, or encounters an error the device-to-host fis is expected to arrive in the unsolicited frame queue to pass to libata for disposition. However, in the DONE_UNEXP_FIS (data underrun) case it appears we need to craft a response. In the DONE_REG_ERR case we do receive the UF and propagate it to libsas.

First one will result in not retrying an a task that report IO_OPEN_CNX_ERROR_HW_RESOURCE_BUSY, the second will result in cosmetic debug printk conflicting statement stutter. Because checkpatch.pl came up with a warning regarding unnecessary space before a newline on one of the fragments associated with the diff context, I took the liberty of fixing all the cases of this issue in the pair of files touched by this defect.

| | | | | | | | | | | | | | | When the ipr driver decides to dump the adapter, it changes the sdt_state to GET_DUMP, then prepares the adapter so that the dump can be read. However, if the ipr worker thread wakes up for some reason before the driver has put the adapter in a state where it can succesfully dump the adapter, the driver will start dumping the adapter too early, which can potentially trigger a BUG check in the pci config blocking API. Fix this by adding a new sdt_state to differentiate between the ipr driver wanting to dump the adapter in the near future and wanting to dump the adapter now.
