Subject: [PATCHSET] libata: improve ATAPI data transfer handling, take #2
Date: Thu, 29 Nov 2007 23:33:23 +0900 [thread overview]
Message-ID: <1196346817387-git-send-email-htejun@gmail.com> (raw)
Hello,
This is the second take of improve-ATAPI-data-transfer patchset.
Changes from the last take [L] are.
* 0005-libata-make-data_xfer-return-the-number-of-consum.patch added
which converts ->data_xfer to return the number of consumed bytes.
* 0006-libata-improve-ATAPI-draining.patch is fixed and updated.
Drain limit check is fixed. Now both partial and whole chunk
draining uses the correct byte count. LLDs doing 32bit IO can now
drain properly instead of draining twice as much. Also, draining is
done in large chunks (PAGE_SIZE at maximum).
* ata_drain_page allocation is moved to 0006 from
0012-libata-implement-ATAPI-drain-buffer.patch.
This patchset is against
#upstream (51a7ee37eaa85b8c35fe6090618e34ed4ce1d316)
+ improve-speed-down patchset, take #3 [1]
+ improve-timing-cod-and-fix-pata_amd, take #2 [2]
This patchset is also available as the following git tree.
master.kernel.org:/pub/scm/linux/kernel/git/tj/libata-dev.git improve-ATAPI-data-transfer
Thanks.
