scsi: imm: Declare SCSI host template const

2023-03-24T23:19:56+00:00

Make it explicit that the SCSI host template is not modified. Signed-off-by: Bart Van Assche Link: https://lore.kernel.org/r/20230322195515.1267197-46-bvanassche@acm.org Signed-off-by: Martin K. Petersen

scsi: imm: Move the SCSI pointer to private command data

2022-02-23T02:11:04+00:00

Set .cmd_size in the SCSI host template instead of using the SCSI pointer. This patch prepares for removal of the SCSI pointer from struct scsi_cmnd.

scsi: core: Remove the 'done' argument from SCSI queuecommand_lck functions

2021-10-17T01:32:16+00:00

The DEF_SCSI_QCMD() macro passes the addresses of the SCSI host lock and also that of the scsi_done function to the queuecommand_lck() function implementations. Remove the 'scsi_done' argument since its address is now a constant and instead call 'scsi_done' directly from inside the queuecommand_lck() functions.

scsi: imm: Call scsi_done() directly

Conditional statements are faster than indirect calls. Hence call scsi_done() directly. Link: https://lore.kernel.org/r/20211007202923.2174984-40-bvanassche@acm.org Signed-off-by: Bart Van Assche Signed-off-by: Martin K. Petersen

2019-07-11T22:17:41+00:00

Pull SCSI scatter-gather list updates from James Bottomley: "This topic branch covers a fundamental change in how our sg lists are allocated to make mq more efficient by reducing the size of the preallocated sg list. This necessitates a large number of driver changes because the previous guarantee that if a driver specified SG_ALL as the size of its scatter list, it would get a non-chained list and didn't need to bother with scatterlist iterators is now broken and every driver *must* use scatterlist iterators. This was broken out as a separate topic because we need to convert all the drivers before pulling the trigger and unconverted drivers kept being found, necessitating a rebase" * tag 'scsi-sg' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (21 commits) scsi: core: don't preallocate small SGL in case of NO_SG_CHAIN scsi: lib/sg_pool.c: clear 'first_chunk' in case of no preallocation scsi: core: avoid preallocating big SGL for data scsi: core: avoid preallocating big SGL for protection information scsi: lib/sg_pool.c: improve APIs for allocating sg pool scsi: esp: use sg helper to iterate over scatterlist scsi: NCR5380: use sg helper to iterate over scatterlist scsi: wd33c93: use sg helper to iterate over scatterlist scsi: ppa: use sg helper to iterate over scatterlist scsi: pcmcia: nsp_cs: use sg helper to iterate over scatterlist scsi: imm: use sg helper to iterate over scatterlist scsi: aha152x: use sg helper to iterate over scatterlist scsi: s390: zfcp_fc: use sg helper to iterate over scatterlist scsi: staging: unisys: visorhba: use sg helper to iterate over scatterlist scsi: usb: image: microtek: use sg helper to iterate over scatterlist scsi: pmcraid: use sg helper to iterate over scatterlist scsi: ipr: use sg helper to iterate over scatterlist scsi: mvumi: use sg helper to iterate over scatterlist scsi: lpfc: use sg helper to iterate over scatterlist scsi: advansys: use sg helper to iterate over scatterlist ...

scsi: imm: use sg helper to iterate over scatterlist

2019-06-20T19:21:33+00:00

Unlike the legacy I/O path, scsi-mq preallocates a large array to hold the scatterlist for each request. This static allocation can consume substantial amounts of memory on modern controllers which support a large number of concurrently outstanding requests. To facilitate a switch to a smaller static allocation combined with a dynamic allocation for requests that need it, we need to make sure all SCSI drivers handle chained scatterlists correctly. Convert remaining drivers that directly dereference the scatterlist array to using the iterator functions.
