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.

If 'scsi_host_alloc()' or 'kcalloc()' fail, 'error' is known to be 0. Set it explicitly to -ENOMEM before branching to the error handling path. While at it, remove 2 useless assignments to 'error'. These values are overwridden a few lines later. Link: https://lore.kernel.org/r/20200412094039.8822-1-christophe.jaillet@wanadoo.frSigned-off-by:

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.comReviewed-by:

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/20200331104015.24868-2-njavali@marvell.comReported-by:kbuild test robot <lkp@intel.com> Reviewed-by:

The MFW may make a call to qed and then to qedf for protocol statistics while the function is still probing. If this happens it's possible that some members of the struct qedf_ctx may not be fully initialized which can result in a NULL pointer dereference or general protection fault. To prevent this, add a new flag call QEDF_PROBING and set it when the __qedf_probe() function is active. Then in the qedf_get_protocol_tlv_data() function we can check if the function is still probing and return immediantely before any uninitialized structures can be touched.
