[nvmewin] Changes for SNTL 1.5 and SCSI Persistent Reserve In/Out

[Thomas Freeman]

Hi Ray,
There were issues with the IEKEY, RACQA, RRELA, RREGA and RTYPE.
I'm attaching a new file with those fixes - SNTL15ResInOut111215.zip (password "nvmehgst").

The code passes Scsi compliance testing (reservation is not enabled)
As before, I am doing a manual validation of PERSISTENT RESERVATION IN/OUT.

Hi Ray,
I don't have hardware to support NVM Reservation Register. So, my testing was limited to issuing individual Scsi Persistent Reserve commands and manually verifying the Scsi to NVMe translation.
As you observed, I missed the IEKEY field. My implementation was based on table 6-35 in the SNTL 1.5. That doesn't mention IEKEY. But, I overlooked the information about IEKEY from table 4-16.
I'll make that change and submit a new patch.

Hi Tom,

Intel has finished their internal testing of this patch. All tests passed with the exception of the MS SCSI Compliance Tests for Persistent Reserve In/Out (see attached file).

We're not sure if the failures are due to IEKEY field not being handled in Persistent Reserve Out command. Was this something that was intentionally left out? Were you able to try the SCSI compliance test?

Thanks,
Ray

Hello all,

I extended the review period for this patch to allow for more time. We're coming up on the end of the year and I'd like to wrap up all planned patches.

Intel is wrapping up our review of this patch and will send out our feedback by the end of the week. Still awaiting feedback from Samsung and PMC. In order to keep to our original schedule, I'd like to wrap this patch up as soon as possible. Intel will be next with the namespace management patch.

Thanks,
Ray

Subject: Changes for SNTL 1.5 and SCSI Persistent Reserve In/Out

This patch includes changes to support SNTL version 1.5, SCSI Persistent Reserve In/Out and a variety of small fixes.

The following tests were successfully run on Windows 2008 R2, Windows 2012 and Windows 2012 R2
1 hour sdstress, 1 hour IOMETER, Quick and Slow format - MBR and GPT, Microsoft Scsi Compliance.

The above tests were run with an NVMe 1.1a compliant device that does not support NVMe Reservations.
Testing variations of Unit SN VPD page/Device ID Data Page (requiring V1.0 or NGUID support) and
SCSI Persistent Reserve In/Out, required setting breakpoints to manually alter the required Identify
data. At that point individual SCSI commands were issued and the driver's response (NVMe commands
issued and data returned) was manually verified.

The attached file, SNTL15ResInOut.zip, contains a Patch file, a copy of the source code and a Log file detailing the changes made.
The password for the file is "nvmehgst"
