2020-07-08scsi: cxgb4i: Add support for iSCSI segmentation offloadVarun Prakash
T5/T6 adapters support iSCSI segmentation offload. To transmit iSCSI PDUs using ISO driver provides iSCSI header and data scatterlist to the adapter, adapter forms multiple iSCSI PDUs and transmits them.

2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2019-07-11Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsiLinus Torvalds
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 ...

This is something we really should not do anyway, as a driver symbol should never select another major subsystem, so let's turn that into a 'depends on'.

Pull SCSI updates from James Bottomley: "This update includes the usual round of major driver updates (ncr5380, lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas). There's also an assortment of minor fixes, mostly in error legs or other not very user visible stuff. The major change is the pci_alloc_irq_vectors replacement for the old pci_msix_.. calls; this effectively makes IRQ mapping generic for the drivers and allows blk_mq to use the information" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (256 commits) scsi: qla4xxx: switch to pci_alloc_irq_vectors scsi: hisi_sas: support deferred probe for v2 hw scsi: megaraid_sas: switch to pci_alloc_irq_vectors scsi: scsi_devinfo: remove synchronous ALUA for NETAPP devices scsi: be2iscsi: set errno on error path scsi: be2iscsi: set errno on error path scsi: hpsa: fallback to use legacy REPORT PHYS command scsi: scsi_dh_alua: Fix RCU annotations scsi: hpsa: use %phN for short hex dumps scsi: hisi_sas: fix free'ing in probe and remove scsi: isci: switch to pci_alloc_irq_vectors scsi: ipr: Fix runaway IRQs when falling back from MSI to LSI scsi: dpt_i2o: double free on error path scsi: cxlflash: Migrate scsi command pointer to AFU command scsi: cxlflash: Migrate IOARRIN specific routines to function pointers scsi: cxlflash: Cleanup queuecommand() scsi: cxlflash: Cleanup send_tmf() scsi: cxlflash: Remove AFU command lock scsi: cxlflash: Wait for active AFU commands to timeout upon tear down scsi: cxlflash: Remove private command pool ...
2016-11-30scsi: cxgb4i: Add a missing call to neigh_releaseQuentin Lambert

2016-11-18cxgb4: Allocate Tx queues dynamicallyHariprasad Shenai
Allocate resources dynamically for Upper layer driver's (ULD) like cxgbit, iw_cxgb4, cxgb4i and chcr. The resources allocated include Tx queues which are allocated when ULD register with cxgb4 driver and freed while un-registering. The Tx queues which are shared by ULD shall be allocated by first registering driver and un-allocated by last unregistering driver.
