[nvmewin] PMC New Patch

[Foster, Carolyn D]

Hi Alex,

Were you able to test S4 as a boot device?  I am seeing some issues with the IO during hiber driver execution.  The hiber driver enumeration and initialization seems to complete with no issues, but after the first call to start io for the inquiry, I'm not seeing any more IO happen.  I will try to debug further, but is this something you can look into?

Thanks,
Carolyn

In order to speed up the entire process and meet our next release date, please review the changes and provide feedbacks as soon as possible. For each outstanding patch, we collect feedbacks for about a week after it is being sent out. A revised patch shall be sent out to include the feedbacks. I will follow up for approval after a week or so to allow more testing and reviewing if necessary.
Summary of changes:

1.       SRB Extension support for Windows 8 and up.

Files changed: nvmeStd.c, nvmeSnti.c, nvmeStat.c, nvmePwrMgmt.c, nvmeInit.c and the related header files.
