scsi: mpi3mr: Select CONFIG_SCSI_SAS_ATTRS

2022-10-22T03:14:51Z

Starting with commit 42fc9fee116f ("scsi: mpi3mr: Add helper functions to manage device's port"), kernel configured with CONFIG_SCSI_MPI3MR=m and CONFIG_SCSI_SAS_ATTRS=n fails to build because modpost cannot find symbols used in mpi3mr_transport.c: ERROR: modpost: "sas_port_alloc_num" [drivers/scsi/mpi3mr/mpi3mr.ko] undefined!

Pull SCSI updates from James Bottomley: "Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr, mpt3sas, target). The biggest change (from my biased viewpoint) being that the mpi3mr now attached to the SAS transport class, making it the first fusion type device to do so. Beyond the usual bug fixing and security class reworks, there aren't a huge number of core changes" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (141 commits) scsi: iscsi: iscsi_tcp: Fix null-ptr-deref while calling getpeername() scsi: mpi3mr: Remove unnecessary cast scsi: stex: Properly zero out the passthrough command structure scsi: mpi3mr: Update driver version to 8.2.0.3.0 scsi: mpi3mr: Fix scheduling while atomic type bug scsi: mpi3mr: Scan the devices during resume time scsi: mpi3mr: Free enclosure objects during driver unload scsi: mpi3mr: Handle 0xF003 Fault Code scsi: mpi3mr: Graceful handling of surprise removal of PCIe HBA scsi: mpi3mr: Schedule IRQ kthreads only on non-RT kernels scsi: mpi3mr: Support new power management framework scsi: mpi3mr: Update mpi3 header files scsi: mpt3sas: Revert "scsi: mpt3sas: Fix ioc->base_readl() use" scsi: mpt3sas: Revert "scsi: mpt3sas: Fix writel() use" scsi: wd33c93: Remove dead code related to the long-gone config WD33C93_PIO scsi: core: Add I/O timeout count for SCSI device scsi: qedf: Populate sysfs attributes for vport scsi: pm8001: Replace one-element array with flexible-array member scsi: 3w-xxxx: Replace one-element array with flexible-array member scsi: hptiop: Replace one-element array with flexible-array member in struct hpt_iop_request_ioctl_command() ...

scsi: mpi3mr: Remove unnecessary cast

2022-09-25T17:49:52Z

Handle the 0xF003 controller fault code as a special case by marking the controller as unrecoverable with logging a message indicating the driver marks the controller as unrecoverable due to the specific fault.

scsi: mpi3mr: Graceful handling of surprise removal of PCIe HBA

2022-09-25T17:49:52Z

Implement graceful handling of surprise or orderly removal of PCIe HBA: - Detect a hot removal of the controller at certain critical places in the driver. Early detection will help to reduce the time taken for cleaning up the hot-removed controller at the driver level. - Poll the status of the port enable issued after reset once every 5 seconds to avoid a long delay in detecting unavailable controller.

2022-09-25T17:49:51Z

In RT kernels, the IRQ handler's code is executed as a kernel thread. Modify the driver to avoid explicitly scheduling the IRQ kernel thread. Link: https://lore.kernel.org/r/20220912135742.11764-4-sreekanth.reddy@broadcom.com Signed-off-by: Sreekanth Reddy Signed-off-by: Martin K. Petersen
