block: remove the blk_integrity_profile structure

2024-06-14T16:20:06+00:00

Block layer integrity configuration is a bit complex right now, as it indirects through operation vectors for a simple two-dimensional configuration: a) the checksum type of none, ip checksum, crc, crc64 b) the presence or absence of a reference tag Remove the integrity profile, and instead add a separate csum_type flag which replaces the existing ip-checksum field and a new flag that indicates the presence of the reference tag. This removes up to two layers of indirect calls, remove the need to offload the no-op verification of non-PI metadata to a workqueue and generally simplifies the code. The downside is that block/t10-pi.c now has to be built into the kernel when CONFIG_BLK_DEV_INTEGRITY is supported. Given that both nvme and SCSI require t10-pi.ko, it is loaded for all usual configurations that enabled CONFIG_BLK_DEV_INTEGRITY already, though.

scsi: qla2xxx: Indent help text

2024-04-09T02:01:19+00:00

Fix indentation of config option's help text by adding leading spaces. Generally help text is indented by couple of spaces more beyond the leading tab <\t> character. It helps Kconfig parsers to read file without error. Signed-off-by: Prasad Pandit Link: https://lore.kernel.org/r/20240321112438.1759347-1-ppandit@redhat.com Signed-off-by: Martin K. Petersen

Pull more SCSI updates from James Bottomley: "The vfs has long had a write lifetime hint mechanism that gives the expected longevity on storage of the data being written. f2fs was the original consumer of this and used the hint for flash data placement (mostly to avoid write amplification by placing objects with similar lifetimes in the same erase block). More recently the SCSI based UFS (Universal Flash Storage) drivers have wanted to take advantage of this as well, for the same reasons as f2fs, necessitating plumbing the write hints through the block layer and then adding it to the SCSI core. The vfs write_hints already taken plumbs this as far as block and this completes the SCSI core enabling based on a recently agreed reuse of the old write command group number. The additions to the scsi_debug driver are for emulating this property so we can run tests on it in the absence of an actual UFS device" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: scsi_debug: Maintain write statistics per group number scsi: scsi_debug: Implement GET STREAM STATUS scsi: scsi_debug: Implement the IO Advice Hints Grouping mode page scsi: scsi_debug: Allocate the MODE SENSE response from the heap scsi: scsi_debug: Rework subpage code error handling scsi: scsi_debug: Rework page code error handling scsi: scsi_debug: Support the block limits extension VPD page scsi: scsi_debug: Reduce code duplication scsi: sd: Translate data lifetime information scsi: scsi_proto: Add structures and constants related to I/O groups and streams scsi: core: Query the Block Limits Extension VPD page

scsi: jazz_esp: Only build if SCSI core is builtin

2024-02-15T20:34:47+00:00

JAZZ_ESP is a bool kconfig symbol that selects SCSI_SPI_ATTRS. When CONFIG_SCSI=m, this results in SCSI_SPI_ATTRS=m while JAZZ_ESP=y, which causes many undefined symbol linker errors. Fix this by only offering to build this driver when CONFIG_SCSI=y. [mkp: JAZZ_ESP is unique in that it does not support being compiled as a module unlike the remaining SPI SCSI HBA drivers] Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Randy Dunlap Link: https://lore.kernel.org/r/20240214055953.9612-1-rdunlap@infradead.org Cc: Thomas Bogendoerfer Cc: linux-mips@vger.kernel.org Cc: Arnd Bergmann Cc: Masahiro Yamada Cc: Nicolas Schier Cc: James E.J.

scsi: ppa: Add a module parameter for the transfer mode

2023-08-21T20:32:40+00:00

I have an Iomega Z100P2 zip drive, but it does not work with my StarTech PEX1P2 AX99100 PCIe parallel port, which evidently does not support 16-bit or 32-bit EPP. Currently the only way to tell the PPA driver to use 8-bit EPP is to write 'mode=3' to /proc/scsi/ppa/*, but the driver doesn't actually distinguish between the three EPP modes and still tries to use 16-bit or 32-bit EPP. And even if writing to that file did make the driver use 8-bit EPP, it still wouldn't do me any good because by the time that file exists, the drive has already failed to initialize. Add a new parameter /sys/module/ppa/mode to set the transfer mode before initializing the drive. This parameter replaces the use of CONFIG_SCSI_IZIP_EPP16 in the PPA driver. At the same time, default to 8-bit EPP. 16-bit and 32-bit EPP are not necessary for the drive to function, nor are they part of the IEEE 1284 standard, so the driver should not assume that they are available.
