Subject: [PATCH V5 00/13] mmc: Add Command Queue support
Date: Thu, 10 Aug 2017 15:08:05 +0300 [thread overview]
Message-ID: <1502366898-23691-1-git-send-email-adrian.hunter@intel.com> (raw)
Hi
Here is V5 of the hardware command queue patches without the software
command queue patches.
HW CMDQ offers 25% - 50% better random multi-threaded I/O. I see a slight
2% drop in sequential read speed but no change to sequential write.
Changes since V4:
mmc: core: Add mmc_retune_hold_now()
Add explanation to commit message.
mmc: host: Add CQE interface
Add comments to callback declarations.
mmc: core: Turn off CQE before sending commands
Add explanation to commit message.
mmc: core: Add support for handling CQE requests
Add comments as requested by Ulf.
mmc: core: Remove unused MMC_CAP2_PACKED_CMD
New patch.
mmc: mmc: Enable Command Queuing
Adjust for removal of MMC_CAP2_PACKED_CMD.
Add a comment about Packed Commands.
mmc: mmc: Enable CQE's
Remove un-necessary check for MMC_CAP2_CQE
mmc: block: Use local variables in mmc_blk_data_prep()
New patch.
mmc: block: Prepare CQE data
Adjust due to "mmc: block: Use local variables in mmc_blk_data_prep()"
Remove priority setting.
Add explanation to commit message.
mmc: cqhci: support for command queue enabled host
Fix transfer descriptor setting in cqhci_set_tran_desc() for 32-bit DMA
Changes since V3:
Adjusted ...blk_end_request...() for new block status codes
Fixed CQHCI transaction descriptor for "no DCMD" case
Changes since V2:
Dropped patches that have been applied.
Re-based
Added "mmc: sdhci-pci: Add CQHCI support for Intel GLK"
Changes since V1:
"Share mmc request array between partitions" is dependent
on changes in "Introduce queue semantics", so added that
and block fixes:
Added "Fix is_waiting_last_req set incorrectly"
Added "Fix cmd error reset failure path"
Added "Use local var for mqrq_cur"
Added "Introduce queue semantics"
Changes since RFC:
Re-based on next.
Added comment about command queue priority.
Added some acks and reviews.
