2020-07-08scsi: docs: Remove invalid link and update text for zfcp kernel configBenjamin Block1-5/+10
IBM decided to retire a lot of the content that was previously hosted on "developerworks", and so some of the links we've used for documentation are now dead or redirect to some general landing page with no correlation to what the links were meant to provide. Change the provided link in the Kconfig file for zfcp to rather refer to our device drivers book that we regularly update and publish for free, and whose name hasn't been changed since it was first published. Our hardware is also not called "IBM eServer zSeries" anymore - in fact, it hasn't been called like that since 2006. Use a broader term that covers different server names over time. Lastly, add a short paragraph about how our HBAs are typically named, to have some more tangible references.

2020-03-26ata: make SATA_PMP option selectable only if any SATA host driver is enabledBartlomiej Zolnierkiewicz1-0/+1
There is no reason to expose SATA_PMP config option when no SATA host drivers are enabled. To fix it add SATA_HOST config option, make all SATA host drivers select it and finally make SATA_PMP config options depend on it. This also serves as preparation for the future changes which optimize libata core code size on PATA only setups. CC: "James E.J. Bottomley" <jejb@linux.ibm.com> Reviewed-by: Martin K.

This kernel configuration is basically enabling/disabling sr driver quirks detection. While these quirks are for fairly rare devices (very old CD burners, and a glucometer), the additional detection of these models is a very minimal amount of code. The logic behind the quirks is always built into the sr driver. This also removes the config from all the defconfig files that are enabling this already.

Currently t10-pi can only be built into the block layer which via crc-t10dif pulls in a whole chunk of the Crypto API. In fact all users of t10-pi work as modules and there is no reason for it to always be built-in. This patch adds a new hidden option for t10-pi that is selected automatically based on BLK_DEV_INTEGRITY and whether the users of t10-pi are built-in or not.

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 ...

2019-01-22scsi/atari_scsi: Don't select CONFIG_NVRAMFinn Thain1-3/+3
On powerpc, setting CONFIG_NVRAM=n builds a kernel with no NVRAM support. Setting CONFIG_NVRAM=m enables the /dev/nvram misc device module without enabling NVRAM support in drivers. Setting CONFIG_NVRAM=y enables the misc device (built-in) and also enables NVRAM support in drivers. m68k shares the valkyriefb driver with powerpc, and since that driver uses NVRAM, it is affected by CONFIG_ATARI_SCSI, because of the use of "select NVRAM". We can avoid the "select" here, but drivers still have to interpret the CONFIG_NVRAM symbol consistently regardless of platform. In this patch and the subsequent fbdev driver patch, the convention is adopted across all relevant platforms whereby NVRAM functionality gets enabled in a given device driver when the nvram misc device is built-in or when both drivers are modules.

2018-11-05scsi: myrs: only build on little-endian platformsArnd Bergmann1-0/+1
Reading throught the new driver, I noticed that this cannot work on big-endian CPUs, and the old DAC960 had exactly the same behavior. To document this for the future, add a Kconfig dependency that prevents it from being included in big-endian kernels. Since the hardware is really old and we never had a working driver on it for big-endian platforms, it's unlikely to make a difference to users.

Pull SCSI updates from James Bottomley: "This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380, qla2xxx, lpfc, libsas, hisi_sas. In addition there's a set of mostly small updates to the target subsystem a set of conversions to the generic DMA API, which do have some potential for issues in the older drivers but we'll handle those as case by case fixes. A new myrs driver for the DAC960/mylex raid controllers to replace the block based DAC960 which is also being removed by Jens in this merge window. Plus the usual slew of trivial changes" [ "myrs" stands for "MYlex Raid Scsi". Obviously. Silly of me to even wonder. There's also a "myrb" driver, where the 'b' stands for 'block'.

2018-10-17scsi: esp_scsi: De-duplicate PIO routinesFinn Thain1-0/+5
As a temporary measure, the code to implement PIO transfers was duplicated in zorro_esp and mac_esp. Now that it has stabilized move the common code into the core driver but don't build it unless needed. This replaces the inline assembler with more portable writesb() calls. Optimizing the m68k writesb() implementation is a separate patch.

2018-07-10scsi: core: switch to scsi-mq by defaultJohannes Thumshirn1-0/+1
It has been more than one year since we tried to change the default from legacy to multi queue in SCSI with commit c279bd9e406 ("scsi: default to scsi-mq"). But due to issues with suspend/resume and performance problems it had been reverted again with commit cbe7dfa26eee ("Revert "scsi: default to scsi-mq""). In the meantime there have been a substantial amount of performance improvements and suspend/resume got fixed as well, thus we can re-enable scsi-mq without a significant performance penalty.

2018-04-19scsi: zorro_esp: New driver for Amiga Zorro NCR53C9x boardsMichael Schmitz1-0/+14
New combined SCSI driver for all ESP based Zorro SCSI boards for m68k Amiga. Code largely based on board specific parts of the old drivers (blz1230.c, blz2060.c, cyberstorm.c, cyberstormII.c, fastlane.c which were removed after the 2.6 kernel series for lack of maintenance) with contributions by Tuomas Vainikka (TCQ bug tests and workaround) and Finn Thain (TCQ bugfix by use of PIO in extended message in transfer). New Kconfig option and Makefile entries for new Amiga Zorro ESP SCSI driver included in this patch. Use DMA transfers wherever possible, with board-specific DMA set-up functions copied from the old driver code. Three byte reselection messages do appear to cause DMA timeouts. So wire up a PIO transfer routine for these instead. esp_reselect_with_tag explicitly sets esp->cmd_block_dma as target address for the message bytes but PIO requires a virtual address. Substiute kernel virtual address esp->cmd_block in PIO transfer call if DMA address is esp->cmd_block_dma and phase is message in. PIO code taken from mac_esp.c where the reselection timeout issue was debugged and fixed first, with minor macro and function rename.
