scsi: switch ->bios_param() to passing gendisk

2025-08-13T06:59:28Z

Instances are passed struct block_device *bdev argument; the only thing it is used for (if it's used in the first place) is bdev->bd_disk. Might as well pass that in the first place... Reviewed-by: Martin K. Petersen Reviewed-by: Christoph Hellwig Acked-by: Jens Axboe Signed-off-by: Al Viro

scsi: wd719x: Return proper error code when dma_set_mask() fails

2022-03-02T04:56:28Z

During the process of driver probing, the probe function should return < 0 for failure, otherwise the kernel will treat value >= 0 as success. Set 'err' to the error value returned by dma_set_mask() in case of failure.

scsi: wd719x: Stop using the SCSI pointer

2022-02-23T02:11:07Z

Move the DMA handle into the per-command private data instead of using the SCSI pointer from struct scsi_cmnd. This patch prepares for removal of the SCSI pointer from struct scsi_cmnd.

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2019-07-11T22:14:01Z

Pull SCSI updates from James Bottomley: "This is mostly update of the usual drivers: qla2xxx, hpsa, lpfc, ufs, mpt3sas, ibmvscsi, megaraid_sas, bnx2fc and hisi_sas as well as the removal of the osst driver (I heard from Willem privately that he would like the driver removed because all his test hardware has failed). Plus number of minor changes, spelling fixes and other trivia. The big merge conflict this time around is the SPDX licence tags. Following discussion on linux-next, we believe our version to be more accurate than the one in the tree, so the resolution is to take our version for all the SPDX conflicts" Note on the SPDX license tag conversion conflicts: the SCSI tree had done its own SPDX conversion, which in some cases conflicted with the treewide ones done by Thomas & co. In almost all cases, the conflicts were purely syntactic: the SCSI tree used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the treewide conversion had used the new-style ones ("GPL-2.0-only" and "GPL-2.0-or-later"). In these cases I picked the new-style one. In a few cases, the SPDX conversion was actually different, though. As explained by James above, and in more detail in a pre-pull-request thread: "The other problem is actually substantive: In the libsas code Luben Tuikov originally specified gpl 2.0 only by dint of stating: * This file is licensed under GPLv2. In all the libsas files, but then muddied the water by quoting GPLv2 verbatim (which includes the or later than language). So for these files Christoph did the conversion to v2 only SPDX tags and Thomas converted to v2 or later tags" So in those cases, where the spdx tag substantially mattered, I took the SCSI tree conversion of it, but then also took the opportunity to turn the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag. Similarly, when there were whitespace differences or other differences to the comments around the copyright notices, I took the version from the SCSI tree as being the more specific conversion. Finally, in the spdx conversions that had no conflicts (because the treewide ones hadn't been done for those files), I just took the SCSI tree version as-is, even if it was old-style. The old-style conversions are perfectly valid, even if the "-only" and "-or-later" versions are perhaps more descriptive. * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (185 commits) scsi: qla2xxx: move IO flush to the front of NVME rport unregistration scsi: qla2xxx: Fix NVME cmd and LS cmd timeout race condition scsi: qla2xxx: on session delete, return nvme cmd scsi: qla2xxx: Fix kernel crash after disconnecting NVMe devices scsi: megaraid_sas: Update driver version to 07.710.06.00-rc1 scsi: megaraid_sas: Introduce various Aero performance modes scsi: megaraid_sas: Use high IOPS queues based on IO workload scsi: megaraid_sas: Set affinity for high IOPS reply queues scsi: megaraid_sas: Enable coalescing for high IOPS queues scsi: megaraid_sas: Add support for High IOPS queues scsi: megaraid_sas: Add support for MPI toolbox commands scsi: megaraid_sas: Offload Aero RAID5/6 division calculations to driver scsi: megaraid_sas: RAID1 PCI bandwidth limit algorithm is applicable for only Ventura scsi: megaraid_sas: megaraid_sas: Add check for count returned by HOST_DEVICE_LIST DCMD scsi: megaraid_sas: Handle sequence JBOD map failure at driver level scsi: megaraid_sas: Don't send FPIO to RL Bypass queue scsi: megaraid_sas: In probe context, retry IOC INIT once if firmware is in fault scsi: megaraid_sas: Release Mutex lock before OCR in case of DCMD timeout scsi: megaraid_sas: Call disable_irq from process IRQ poll scsi: megaraid_sas: Remove few debug counters from IO path ...

scsi: wd719x: Fix resets and aborts

2019-06-20T19:37:02Z

Host reset oopses because it calls wd719x_chip_init, which calls request_firmware, under a spinlock. Stop the RISC first, then flush active SCBs under a spinlock. Finally call wd719x_chip_init unlocked. Also found and fixed more bugs during tests: Affected active SCBs were not flushed during abort, bus and device reset. This caused problems in a following host reset (hang or oops). Device and bus reset failed under load because the result of the reset command is WD719X_SUE_TERM or WD719X_SUE_RESET. Don't treat these codes as error in wd719x_wait_done. wd719x_direct_cmd for RESET/ABORT commands didn't work properly, causing timeouts. Looks like it was caused by the WD719X_DISABLE_INT bit. Not setting it for RESET/ABORT commands seems to fix the probem. Also lower the log level of the corresponding "direct command completed" message to debug. Unfortunately, my documentation is missing some pages, including page 67 (SPIDER67.gif) about resets :( Reported-by: Hariprasad Kelam Signed-off-by: Ondrej Zary Signed-off-by: Martin K. Petersen

scsi: flip the default on use_clustering

2018-12-19T04:13:12Z

Most SCSI drivers want to enable "clustering", that is merging of segments so that they might span more than a single page. Remove the ENABLE_CLUSTERING define, and require drivers to explicitly set DISABLE_CLUSTERING to disable this feature. Signed-off-by: Christoph Hellwig Signed-off-by: Martin K. Petersen
