I may or may not attend the next Windows driver meeting.
However, I have observed the following with the last release:

Disk format using Windows 7 driver on both Windows 7 and Windows 8 is faster than using Windows 8 driver on Windows 8 and it is slower than Windows 8.1/2012 R2 inbox drivers.

I am not sure whether anyone is using Windows 8 at this time, since Windows 8.1 and Windows Server 2012 R2 are the current versions.

Please test and fix the issue with the Windows 8 driver on Windows 8 (not 8.1) before next release and the community driver should be on par with the inbox drivers.

Thank you,
Uma

It might not hurt to have a fourth required reviewer – the more eyes the better. Perhaps we could vote on that as well?

Thanks,
Judy

Hi Tom,

Thank you for responding and offering to be a required reviewer. It is perfectly understandable on the required testing component. NVMe is still very much in the early stages.

As noted in my meeting minutes from our initial 2015 meeting, Samsung has agreed to be a reviewer and tester, if approved upon by the working group. I will send out a meeting invite in the next day or two and we can put forth the vote on Samsung.
Again, thank you for following up.

Thanks,
Ray

HGST will commit to being a required reviewer.
Unfortunately, we cannot commit to the required testing.

Meeting Minutes (Friday 1/23/15) – OFA NVMe Windows Driver Q1`2015 Meeting

Agenda:

-          Review 1.4 Release (Kwok – PMC)

-          Confirmation of Ray and Carolyn as the chairperson and source maintainer (All)

-          Planning for 2016 and beyond (Ray)

-          AOB

Opens:

-          PMC: Kwok nominated Intel reps Raymond Robles and Carolyn Foster to take over OFA chair and source maintainer role, respectively, for 2015. No objections from working group. Ray and Carolyn will take over roles effective immediately. A huge thanks to Kwok and Alex for all their hard work over the last year.

-          Dell: How will future releases be WHQL’d? 1.4 release was WHQL’d with PMC hardware. Identify a WHQL strategy moving forward for OFA driver (which hardware, who owns the WHQL certification process, price, etc.).

-          Intel: Confirm with OFA working group on any changes to driver releases, planning meetings, and cadence. Working group agreed to keep all planning items “as is”.

-          Intel: Requested a replacement for LSI/Avago/Seagate as a mandatory reviewing member company. A vote was taken on whether a 3rd mandatory company was needed (for reviewing and testing). Approved.

o    Dell: Abstain

o    Intel: Yes

o    Samsung: Yes

o    PMC: Yes

o    HGST: Abstain

-          Intel: With the working group approving the need for a 3rd mandatory reviewing member company, a request for volunteers was made by Intel. Kwok suggested Samsung. HGST was suggested by Judy.

o    Samsung: Will follow up with management and notify OFA working group within 2 weeks (AR: Judy - 2 weeks)

o    HGST: Will follow up with management and notify OFA working group within 2 weeks (AR: Tom - 2 weeks)

-          Intel: Open discussion on features for 2015 OFA releases:

o    Intel:

•  NVMe 1.1/1.2 features. Discussion on mandatory and optional features. Follow up discussion needed to close.

•  Start I/O Concurrent Channels (potential performance increase on high core counts).

o    Samsung:

•  Instead of learning cores, use perf opts. Shave off 2 seconds in init code… using Storport initialize perf opts. No need for source core interrupt steering code in driver.

•  Storport Notification usage. Hot plug and IOCTLs, this does not work, for Win8.1… StorportRequestTimer() function needed.

•  CFS bit monitoring and handling. Look into adding additional handling code just to monitor CSTS.CFS.

•  Read only support for devices at EOL. Detection at init, hot plug, or run-time.

AR’s:

-          Dell (Austin): Identify initial WHQL strategy for 2015 (mid-February… next meeting to discuss).

-          Samsung (Judy): Follow up with management on becoming 3rd mandatory reviewing member company for OFA (2 weeks).

o    UPDATE (1/30/15): Samsung has agreed to become 3rd mandatory reviewing member company. Thanks Judy!

-          HGST (Ken): Follow up with management on becoming 3rd mandatory reviewing member company for OFA (2 weeks).

-          Intel (Ray): Provide preliminary list of 1.1/1.2 features, both mandatory and optional, to start discussion on what to include in 2015 releases.

-          Intel (Ray): Communicate with Ken Strandberg at OFA website for logistical changes (mid-February… next meeting).

Next Meeting:

-          Mid February 2015… to plan for next release and finalize feature list for 2015 OFA driver releases.

Thanks,
Ray
