2020-04-27scsi: ufs: Add write booster feature supportAsutosh Das3-6/+291
The write performance of TLC NAND is considerably lower than SLC NAND. Using SLC NAND as a WriteBooster Buffer enables the write request to be processed with lower latency and improves the overall write performance. Adds support for shared-buffer mode WriteBooster. WriteBooster enable: SW enables it when clocks are scaled up, thus it's enabled only in high load conditions. WriteBooster disable: SW will disable the feature, when clocks are scaled down. Thus writes would go as normal writes. To keep the endurance of the WriteBooster Buffer at a maximum, this load-based toggling is adopted.

2020-04-24scsi: core: Avoid calling synchronize_rcu() for each device in scsi_host_block()Ming Lei1-1/+17
scsi_host_block() calls scsi_internal_device_block() for each scsi_device and scsi_internal_device_block() calls blk_mq_quiesce_queue() for each LUN. Since synchronize_rcu() is called from blk_mq_quiesce_queue(), this can cause substantial slowdowns on systems with many LUNs. Use scsi_internal_device_block_nowait() to implement scsi_host_block() so it is sufficient to run synchronize_rcu() once. This is safe since SCSI does not set the BLK_MQ_F_BLOCKING flag.

For INVADER_SERIES, each set of 8 reply queues (0 - 7, 8 - 15,..), and for VENTURA_SERIES, each set of 16 reply queues (0 - 15, 16 - 31,..) need to be within the same 4 GB boundary. Driver uses limitation of VENTURA_SERIES to manage INVADER_SERIES as well. The driver is allocating the DMA able memory for RDPQs accordingly. 1) At driver load, set DMA mask to 64 and allocate memory for RDPQs 2) Check if allocated resources for RDPQ are in the same 4GB range 3) If #2 is true, continue with 64 bit DMA and go to #6 4) If #2 is false, then free all the resources from #1 5) Set DMA mask to 32 and allocate RDPQs 6) Proceed with driver loading and other allocations Link: https://lore.kernel.org/r/1587626596-1044-5-git-send-email-suganath-prabu.subramani@broadcom.com Reviewed-by: Christoph Hellwig <[email protected]> Signed-off-by: Suganath Prabu <[email protected]> Signed-off-by: Martin K.

Today, upon an MPI failure AEN, on top of collecting an MPI dump, a regular firmware dump is also taken and then chip reset. This is disruptive to IOs and not required. Make the firmware dump collection, followed by chip reset, optional (not done by default). Firmware dump buffer and MPI dump buffer are independent of each other with this change and each can have dump that was taken at two different times for two different issues. The MPI dump is saved in a separate buffer and is retrieved differently from firmware dump. To collect full dump on MPI failure AEN, a module parameter is introduced: ql2xfulldump_on_mpifail (default: 0) Link: https://lore.kernel.org/r/[email protected] Reported-by: kbuild test robot <[email protected]> Reviewed-by: Himanshu Madhani <[email protected]> Signed-off-by: Arun Easi <[email protected]> Signed-off-by: Nilesh Javali <[email protected]> Signed-off-by: Martin K.
