2017-10-25scsi: hisi_sas: use array for v2 hw AXI errorsShiju Jose
The code to print AXI errors in v2 hw driver is repetitive. This patch condenses the code by looping an array of errors. Also, a formatting error in one_bit_ecc_errors[] and multi_bit_ecc_errors[] is fixed.

2017-10-25scsi: hisi_sas: fix the risk of freeing slot twiceXiaofei Tan
The function hisi_sas_slot_task_free() is used to free the slot and do tidy-up of LLDD resources. The LLDD generally should know the state of a slot and decide when to free it, and it should only be done once. For some scenarios, we really don't know the state, like when TMF timeout. In this case, we check task->lldd_task before calling hisi_sas_slot_task_free(). However, we may miss some scenarios when we should also check task->lldd_task, and it is not SMP safe to check task->lldd_task as we don't protect it within spin lock. This patch is to fix this risk of freeing slot twice, as follows: 1. Check task->lldd_task in the hisi_sas_slot_task_free(), and give up freeing of this time if task->lldd_task is NULL. 2. Set slot->buf to NULL after it is freed. Signed-off-by: Xiaofei Tan <tanxiaofei@huawei.com> Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Martin K.

2017-10-25scsi: hisi_sas: fix SATA breakpoint memory sizeXiang Chen
Currently the size of memory we allocate for SATA breakpoint buffer is incorrect. The breakpoint memory size should be as follows: 32 (NCQ tags) * 128 * 2048 (max #devs) = 8MB Currently we only allocate 0.5MB, but get away with it as we never have SATA device index > 128 typically. To conserve precious DMA memory (8MB may not be even available), limit the number of devices per HBA to 1024, which means 4MB of memory required for SATA breakpoint. The 1024 device limit applied to all HW versions. For v3 hw, we need to configure this value.

2017-10-25scsi: megaraid_sas: Add support for 64bit consistent DMAShivasharan S
The latest MegaRAID Firmware (for Invader series) has support for 64bit DMA for both streaming and consistent DMA buffers. All Ventura series controller FW always support 64 bit consistent DMA. Also, on a few architectures 32bit DMA is not supported. Current driver always prefers 32bit for consistent DMA and 64bit for streaming DMA. This behavior was unintentional and carried forwarded from legacy controller FW. Need to enhance the driver to support 64bit consistent DMA buffers based on the firmware capability. Below is the DMA setting strategy in driver with this patch. For Ventura series, always try to set 64bit DMA mask. If it fails fall back to 32bit DMA mask. For Invader series and earlier generation controllers, first try to set to 32bit consistent DMA mask irrespective of FW capability. This is needed to ensure firmware downgrades do not break. If 32bit DMA setting fails, check FW capability and try seting to 64bit DMA mask. There are certain restrictions in the hardware for having all sense buffers and all reply descriptors to be in the same 4GB memory region. This limitation is h/w dependent and can not be changed in firmware. This limitation needs to be taken care in driver while allocating the buffers.
