92186c14 - scsi: iscsi_tcp: Switch to using the crc32c library

Fri, 07 Feb 2025 04:17:24 +0000

scsi: iscsi_tcp: Switch to using the crc32c libraryNow that the crc32c() library function directly takes advantage ofarchitecture-specific optimizations, it is unnecessary to go through thecrypto API. Just use crc32c(). This is much simpler, and it improvesperformance due to eliminating the crypto API overhead.Signed-off-by: Eric Biggers Link: https://lore.kernel.org/r/20250207041724.70733-1-ebiggers@kernel.orgSigned-off-by: Martin K.

e9f5f44a - block: remove the blk_integrity_profile structure

Thu, 13 Jun 2024 08:48:15 +0000

block: remove the blk_integrity_profile structureBlock layer integrity configuration is a bit complex right now, as itindirects through operation vectors for a simple two-dimensionalconfiguration: a) the checksum type of none, ip checksum, crc, crc64 b) the presence or absence of a reference tagRemove the integrity profile, and instead add a separate csum_type flagwhich replaces the existing ip-checksum field and a new flag thatindicates the presence of the reference tag.This removes up to two layers of indirect calls, remove the need tooffload the no-op verification of non-PI metadata to a workqueue andgenerally simplifies the code. The downside is that block/t10-pi.c nowhas to be built into the kernel when CONFIG_BLK_DEV_INTEGRITY issupported. Given that both nvme and SCSI require t10-pi.ko, it is loadedfor all usual configurations that enabled CONFIG_BLK_DEV_INTEGRITYalready, though.Signed-off-by: Christoph Hellwig Reviewed-by: Kanchan Joshi Reviewed-by: Hannes Reinecke Reviewed-by: Martin K.

68a4f84a - scsi: ppa: Add a module parameter for the transfer mode

Mon, 07 Aug 2023 15:52:58 +0000

scsi: ppa: Add a module parameter for the transfer modeI have an Iomega Z100P2 zip drive, but it does not work with my StarTechPEX1P2 AX99100 PCIe parallel port, which evidently does not support 16-bitor 32-bit EPP. Currently the only way to tell the PPA driver to use 8-bitEPP is to write 'mode=3' to /proc/scsi/ppa/*, but the driver doesn'tactually distinguish between the three EPP modes and still tries to use16-bit or 32-bit EPP. And even if writing to that file did make the driveruse 8-bit EPP, it still wouldn't do me any good because by the time thatfile exists, the drive has already failed to initialize.Add a new parameter /sys/module/ppa/mode to set the transfer mode beforeinitializing the drive. This parameter replaces the use ofCONFIG_SCSI_IZIP_EPP16 in the PPA driver.At the same time, default to 8-bit EPP. 16-bit and 32-bit EPP are notnecessary for the drive to function, nor are they part of the IEEE 1284standard, so the driver should not assume that they are available.Signed-off-by: Alex Henrie Link: https://lore.kernel.org/r/20230807155856.362864-2-alexhenrie24@gmail.comSigned-off-by: Martin K.

scsi: dpt_i2o: Remove obsolete driverThe dpt_i2o driver was fixed to stop using virt_to_bus() in 2008, but itstill has a stale reference in an error handling code path that could neverwork. I submitted a patch to fix this reference earlier, but HannesReinecke suggested that removing the driver may be just as good here.The i2o driver layer was removed in 2015 with commit 4a72a7af462d("staging: remove i2o subsystem"), but the even older dpt_i2o scsi driverstayed around.The last non-cleanup patches I could find were from Miquel van Smoorenburgand Mark Salyzyn back in 2008, they might know if there is any chance ofthe hardware still being used anywhere.Link: https://lore.kernel.org/linux-scsi/CAK8P3a1XfwkTOV7qOs1fTxf4vthNBRXKNu8A5V7TWnHT081NGA@mail.gmail.com/T/Link: https://lore.kernel.org/r/20220624155226.2889613-3-arnd@kernel.orgCc: Miquel van Smoorenburg Cc: Mark Salyzyn Cc: Hannes Reinecke Signed-off-by: Arnd Bergmann Signed-off-by: Martin K.

9f7c2232 - scsi: BusLogic: Remove bus_to_virt()

Fri, 24 Jun 2022 15:52:24 +0000

scsi: BusLogic: Remove bus_to_virt()The BusLogic driver is the last remaining driver that relies on thedeprecated bus_to_virt() function, which in turn only works on a fewarchitectures, and is incompatible with both swiotlb and iommu support.Before commit 391e2f25601e ("[SCSI] BusLogic: Port driver to 64-bit."), thedriver had a dependency on x86-32, presumably because of thisproblem. However, the change introduced another bug that made it stillimpossible to use the driver on any 64-bit machine.This was in turn fixed in commit 56f396146af2 ("scsi: BusLogic: Fix 64-bitsystem enumeration error for Buslogic"), 8 years later, which shows thatthere are not a lot of users.Maciej is still using the driver on 32-bit hardware, and Khalid mentionedthat the driver works with the device emulation used in VirtualBox andVMware. Both of those only emulate it for Windows 2000 and older operatingsystems that did not ship with the better LSI logic driver.Do a minimum fix that searches through the list of descriptors to find onethat matches the bus address. This is clearly as inefficient as wasindicated in the code comment about the lack of a bus_to_virt()replacement. A better fix would likely involve changing out the entiredescriptor allocation for a simpler one, but that would be much moreinvasive.Link: https://lore.kernel.org/r/20220624155226.2889613-2-arnd@kernel.orgCc: Maciej W.
