2022-09-25scsi: core: Make SCSI_MOD depend on BLOCK for cleaner .config filesLukas Bulwahn1-3/+4
SCSI_MOD is a helper config symbol for configuring RAID_ATTRS properly, i.e., RAID_ATTRS needs to be m when SCSI=m. This helper config symbol SCSI_MOD still shows up even in kernel configurations that do not select the block subsystem and where SCSI is not even a configuration option mentioned and selectable. Make this SCSI_MOD depend on BLOCK, so that it only shows up when it is slightly relevant in the kernel configuration.

2022-06-28scsi: dpt_i2o: Remove obsolete driverArnd Bergmann1-11/+0
The dpt_i2o driver was fixed to stop using virt_to_bus() in 2008, but it still has a stale reference in an error handling code path that could never work. I submitted a patch to fix this reference earlier, but Hannes Reinecke 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 driver stayed around. The last non-cleanup patches I could find were from Miquel van Smoorenburg and Mark Salyzyn back in 2008, they might know if there is any chance of the hardware still being used anywhere.

2022-06-28scsi: BusLogic: Remove bus_to_virt()Arnd Bergmann1-1/+1
The BusLogic driver is the last remaining driver that relies on the deprecated bus_to_virt() function, which in turn only works on a few architectures, and is incompatible with both swiotlb and iommu support. Before commit 391e2f25601e ("[SCSI] BusLogic: Port driver to 64-bit."), the driver had a dependency on x86-32, presumably because of this problem. However, the change introduced another bug that made it still impossible to use the driver on any 64-bit machine. This was in turn fixed in commit 56f396146af2 ("scsi: BusLogic: Fix 64-bit system enumeration error for Buslogic"), 8 years later, which shows that there are not a lot of users. Maciej is still using the driver on 32-bit hardware, and Khalid mentioned that the driver works with the device emulation used in VirtualBox and VMware. Both of those only emulate it for Windows 2000 and older operating systems that did not ship with the better LSI logic driver. Do a minimum fix that searches through the list of descriptors to find one that matches the bus address. This is clearly as inefficient as was indicated in the code comment about the lack of a bus_to_virt() replacement. A better fix would likely involve changing out the entire descriptor allocation for a simpler one, but that would be much more invasive.

Commit d2bcbeab4200 ("scsi: blkcg: Add app identifier support for blkcg") introduced an FC_APPID config option under SCSI. However, the added config option is not used anywhere. Simply remove it. The block layer BLK_CGROUP_FC_APPID config option is what actually controls whether the application ID code should be built or not. Make this option dependent on NVMe over FC since that is currently the only transport which supports the capability.

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.

2019-07-12Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsiLinus Torvalds1-22/+35
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 ...

2019-06-14docs: kbuild: convert docs to ReST and rename to *.rstMauro Carvalho Chehab1-2/+2
The kbuild documentation clearly shows that the documents there are written at different times: some use markdown, some use their own peculiar logic to split sections. Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

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.
