2021-08-12scsi: ufs: ufshpb: Do not report victim error in HCMAvri Altman1-1/+2
In host control mode, eviction is perceived as an extreme measure. There are several conditions that both the entering and exiting regions should meet, so that eviction will take place. The common case however, is that those conditions are rarely met, so it is normal that the act of eviction fails. Therefore, do not report an error in host control mode if eviction fails.

2021-08-12scsi: ufs: ufshpb: Use a correct max multi chunkAvri Altman1-1/+1
In HPB2.0, if pre_req_min_tr_len < transfer_len < pre_req_max_tr_len, the driver is expected to send a HPB-WRITE-BUFFER companion to HPB-READ. The upper bound should fit into a single byte, regardless of bMAX_ DATA_SIZE_FOR_HPB_SINGLE_CMD which being an attribute (u32) can be significantly larger. To further illustrate the issue, consider the following scenario: - SCSI_DEFAULT_MAX_SECTORS is 1024 limiting the I/O chunks to 512KB - The OEM changes scsi_host_template .max_sectors to be 2048 which allows for 1MB requests: transfer_len = 256 - pre_req_max_tr_len = HPB_MULTI_CHUNK_HIGH = 256 - ufshpb_is_supported_chunk() returns true (256 <= 256) - WARN_ON_ONCE(256 > 256) doesn't warn - ufshpb_set_hpb_read_to_upiu() casts transfer_len to u8: transfer_len = 0 - The command is failing with ILLEGAL REQUEST Link: https://lore.kernel.org/r/20210808090024.21721-3-avri.altman@wdc.com Fixes: 41d8a9333cc9 (scsi: ufs: ufshpb: Add HPB 2.0 support) Signed-off-by: Avri Altman <avri.altman@wdc.com> Signed-off-by: Martin K.

2021-08-12scsi: ufs: ufshpb: Rewind the read timeout on every readAvri Altman1-3/+13
The purpose of the "cold"-timer is not to hang-on to active regions with no reads. Therefore the read timeout should be rewound on every read, and not just when the region is activated.

The variable 'rv' is being initialized with a value that is never read, it is being updated later on. The assignment is redundant and can be removed.

2021-08-10scsi: mpt3sas: Fix incorrectly assigned error return and checkColin Ian King1-1/+1
Currently the call to _base_static_config_pages() is assigning the error return to variable 'rc' but checking the error return in error 'r'. Fix this by assigning the error return to variable 'r' instead of 'rc'.
