Subject: [RFC 0/4] mmc: sdhci-msm: Add CQE support for sdhci-msm
Date: Wed, 30 Aug 2017 18:34:07 +0530 [thread overview]
Message-ID: <1504098251-27739-1-git-send-email-riteshh@codeaurora.org> (raw)
Hi All,
Please ignore the previous patch series from a wrong email
address. Stupid gitconfig issue. Apologies for the spam.
This is RFC patch series based on top of ulfh_mmc/cmdq branch
which is based upon Adrian's CMDQ patch series.
Below patch series enables CQE for sdhci-msm platform.
This has been tested on internal 8996 MTP which has CMDQ support.
Fixes w.r.t. CMDQ:-
There are some patches identified which were required atleast on
MSM platform. I am not sure if these are required for any other
CQE platform or not. Patchset 1, 3 & 4 commit text describes
the problems.
Performance related:-
I gave one small shot for performance and the numbers were not looking good.
So, unless I have tested for performance completely, I should not discuss
on performance numbers as of now with this patchset.
I can try doing some more performance testing and post the results -
though this may take some while.
I used below test script for random read/write test.
*randwrite-test-script*
[global]
bs=32k
size=1g
rw=randwrite
direct=1
directory=/data/fiotest
[file1]
filename=singlefile1
*randread-test-script*
[global]
bs=32k
size=1g
rw=randread
directory=/data/fiotest
[file1]
filename=singlefile1
@Adrian,
Thanks a lot for pursuing and bringing CMDQ patch series to it's final stages :)
