The SMP frame response is written to the command table and not the SMP response pointer from libsas, so don't bother DMA mapping (and unmapping) the SMP response from libsas. Suggested-by:

The call to kmap_atomic() in the SMP command completion code is unnecessary, since kmap() is only really concerned with highmem, which is not relevant on arm64. The controller only finds itself in arm64 systems. Signed-off-by:

For a system with PAGE_SIZE of 16K or 64K, the size every time we want to alloc may be small like 4K, but for function dmam_alloc_coherent(), the least size it allocates is PAGE_SIZE, so it will waste much memory for the situation. To solve the issue, limit the minimum allocation size of slot buf to PAGE_SIZE. Signed-off-by:

For struct hisi_sas_status_buffer, it contains struct hisi_sas_err_record and iu[1024]. The struct iu[1024] will be filled fully by the response of disks, so it is not need to initialize them to 0, but for the struct hisi_sas_err_record, SAS controller only fill some fields of hisi_sas_err_record according to hw designer, so it should be initialised to 0. After the change, cpu utilization percentage of memset() is changed from 1.7% to 0.12%. Signed-off-by:

The value of IOST/ITCT is updated to cache first, and then synchronize to DDR periodically. So the value in IOST/ITCT cache is the latest data and it's important for debugging. So, the HW cache of IOST and ITCT should be snapshot at debugfs. Signed-off-by:

In commit 1273d65f ("scsi: hisi_sas: change queue depth from 512 to 4096"), the depth of each queue is the same as the max IPTT in the system. As such, as long as we have an IPTT allocated, we will have enough space on any delivery queue. All .get_free_slot functions were checking for space on the queue by reading the DQ read pointer. Drop this, and also raise the code into common code, as there is nothing hw specific remaining. Signed-off-by:

John Garry authored
There is a small optimisation to be had by making the max IPTT the same for all hw revisions, that being we can drop the check for read and write pointer being the same in the get free slot function. Change v1 hw to have max IPTT of 4096 - same as v2 and v3 hw - and drop hisi_sas_hw.max_command_entries. Signed-off-by:

If the userspace process crashes while we send the nl msg, it is possible that the cmd in curr_nl_cmd of tcmu_dev never gets reset to 0, and and returns busy for other commands after the userspace process is restartd. More details below: /backstores/user:file/file> set attribute dev_size=2048 Cannot set attribute dev_size: [Errno 3] No such process /backstores/user:file/file> set attribute dev_size=2048 Cannot set attribute dev_size: [Errno 16] Device or resource busy with following kernel messages: [173605.747169] Unable to reconfigure device [173616.686674] tcmu daemon: command reply support 1.

Configure CDNS_UFS_REG_HCLKDIV in .hce_enable_notify() instead of .setup_clock() because if UFSHCD resets the controller ip because of phy or device related errors then CDNS_UFS_REG_HCLKDIV is reset to default value and .setup_clock() is not called later in the sequence whereas .hce_enable_notify will be called everytime controller is reenabled.

The data structure used for log messages is so large that it can cause a boot failure. Since allocations from that data structure can fail anyway, use kmalloc() / kfree() instead of that data structure. See also https://bugzilla.kernel.org/show_bug.cgi?id=204119.

The only 'new_state' values passed by upstream kernel code to scsi_internal_device_unblock_nowait() are SDEV_RUNNING and SDEV_TRANSPORT_OFFLINE. These are the only values that should be passed to this function. Hence check the value of the 'new_state' argument to avoid that scsi_internal_device_unblock_nowait() would be used to trigger an illegal SCSI device state transition. In this context 'illegal' means not allowed by scsi_device_set_state().

Current driver report dev_loss_tmo to 0 for NVMe devices with short cable pull. This causes NVMe controller to be freed along with NVMe namespace. The side affect is IO would stop. By not setting dev_loss_tmo to 0, NVMe namespace would stay until cable is plugged back in. This allows IO to resume afterward. [mkp: commit desc] Signed-off-by:

The following sequence of event leads to NVME port disappearing: - device port shut - nvme_fc_unregister_remoteport - device port online - remote port delete completes - relogin is scheduled - "post gidpn" message appears due to rscn generation # mismatch In short, if a device comes back online sooner than an unregister completion, a mismatch in rscn generation number occurs, which is not handled correctly during device relogin. Fix this by starting with a redo of GNL. When ql2xextended_error_logging is enabled, the re-plugged device's discovery stops with the following messages printed: --8<-- qla2xxx [0000:41:00.0]-480d:3: Relogin scheduled. qla2xxx [0000:41:00.0]-4800:3: DPC handler sleeping. qla2xxx [0000:41:00.0]-2902:3: qla24xx_handle_relogin_event 21:00:00:24:ff:17:9e:91 DS 0 LS 7 P 0 del 2 cnfl (null) rscn 1|2 login 1|2 fl 1 qla2xxx [0000:41:00.0]-28e9:3: qla24xx_handle_relogin_event 1666 21:00:00:24:ff:17:9e:91 post gidpn qla2xxx [0000:41:00.0]-480e:3: Relogin end. --8<-- Signed-off-by: -

For any qla2xxx async command, the SRB buffer is used to send it. In setting up the SRB buffer, the timer for this command is started before all memory allocation has finished. Under low memory pressure, memory alloc can go to sleep and not wake up before the timer expires. Once timer has expired, the timer thread will access uninitialize fields resulting into NULL pointer crash. This patch fixes this crash by moving the start of timer after everything is setup. backtrace shows following PID: 3720 TASK: ffff996928401040 CPU: 0 COMMAND: "qla2xxx_1_dpc" 0 [ffff99652751b698] __schedule at ffffffff965676c7 1 [ffff99652751b728] schedule at ffffffff96567bc9 2 [ffff99652751b738] schedule_timeout at ffffffff965655e8 3 [ffff99652751b7e0] io_schedule_timeout at ffffffff9656726d 4 [ffff99652751b810] congestion_wait at ffffffff95fd8d12 5 [ffff99652751b870] isolate_migratepages_range at ffffffff95fddaf3 6 [ffff99652751b930] compact_zone at ffffffff95fdde96 7 [ffff99652751b980] compact_zone_order at ffffffff95fde0bc 8 [ffff99652751ba20] try_to_compact_pages at ffffffff95fde481 9 [ffff99652751ba80] __alloc_pages_direct_compact at ffffffff9655cc31 10 [ffff99652751bae0] __alloc_pages_slowpath at ffffffff9655d101 11 [ffff99652751bbd0] __alloc_pages_nodemask at ffffffff95fc0e95 12 [ffff99652751bc80] dma_generic_alloc_coherent at ffffffff95e3217f 13 [ffff99652751bcc8] x86_swiotlb_alloc_coherent at ffffffff95e6b7a1 14 [ffff99652751bcf8] qla2x00_rft_id at ffffffffc055b5e0 [qla2xxx] 15 [ffff99652751bd50] qla2x00_loop_resync at ffffffffc0533e71 [qla2xxx] 16 [ffff99652751be68] qla2x00_do_dpc at ffffffffc05210ca [qla2xxx] PID: 0 TASK: ffffffff96a18480 CPU: 0 COMMAND: "swapper/0" 0 [ffff99652fc03ae0] machine_kexec at ffffffff95e63674 1 [ffff99652fc03b40] __crash_kexec at ffffffff95f1ce12 2 [ffff99652fc03c10] crash_kexec at ffffffff95f1cf00 3 [ffff99652fc03c28] oops_end at ffffffff9656c758 4 [ffff99652fc03c50] no_context at ffffffff9655aa7e 5 [ffff99652fc03ca0] __bad_area_nosemaphore at ffffffff9655ab15 6 [ffff99652fc03cf0] bad_area_nosemaphore at ffffffff9655ac86 7 [ffff99652fc03d00] __do_page_fault at ffffffff9656f6b0 8 [ffff99652fc03d70] do_page_fault at ffffffff9656f915 9 [ffff99652fc03da0] page_fault at ffffffff9656b758 [exception RIP: unknown or invalid address] RIP: 0000000000000000 RSP: ffff99652fc03e50 RFLAGS: 00010202 RAX: 0000000000000000 RBX: ffff99652b79a600 RCX: ffff99652b79a760 RDX: ffff99652b79a600 RSI: ffffffffc0525ad0 RDI: ffff99652b79a600 RBP: ffff99652fc03e60 R8: ffffffff96a18a18 R9: ffffffff96ee3c00 R10: 0000000000000002 R11: ffff99652fc03de8 R12: ffff99652b79a760 R13: 0000000000000100 R14: ffffffffc0525ad0 R15: ffff99652b79a600 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 10 [ffff99652fc03e50] qla2x00_sp_timeout at ffffffffc0525af8 [qla2xxx] 11 [ffff99652fc03e68] call_timer_fn at ffffffff95ea7f58 12 [ffff99652fc03ea0] run_timer_softirq at ffffffff95eaa3bd 13 [ffff99652fc03f18] __do_softirq at ffffffff95ea0f05 14 [ffff99652fc03f88] call_softirq at ffffffff9657832c 15 [ffff99652fc03fa0] do_softirq at ffffffff95e2e675 16 [ffff99652fc03fc0] irq_exit at ffffffff95ea1285 17 [ffff99652fc03fd8] smp_apic_timer_interrupt at ffffffff965796c8 18 [ffff99652fc03ff0] apic_timer_interrupt at ffffffff96575df2 Signed-off-by: -
