All,

Samsung would like to take up the following patches -

1.Feature - Optimizing driver initialization performance.
Description - Instead of learning cores, use StorPortInitializePerfOpts() to get the array of MSI numbers corresponding to each logical processor and make the Llogical processor-Queue-MSIx mapping.
Submitter - Samsung (Suman)
Date - End of June

2. Feature - Handling device surprise removal in IOCTL path using Win 8.1 Timers.
Description - The existing implementation of detecting surprise removal during IO using the StorPortNotification(RequestTimerCall,..) does not work when IOCTL commands are outstanding. Starting from Windows 8 kernel, StorPortRequestTimer() is supported which handles the surprise removal in IOCTL path too. For Windows 7 kernel, this will be a limitation.
Submitter - Samsung (Suman)
Date - End of July

3. Feature - Device EOF support(Read Only)
Description - Read only support for devices at EOL. Detection at init, hot plug, or run-time.
Submitter - Samsung (Suman)
Date - End of August

Thanks,
Suman

All,

As we enter Q2, I'm happy to announce that we a have a very good feature plan in place for both Q2 and Q4 releases in 2015 of the OFA driver. The list of requested features is included below for final review.

I would like to formally ask for volunteers for patch submissions. As of today, there are no volunteers for any of the below patches.

Intel would like to start with the volunteering... we will volunteer to provide the namespace management patch.

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.

<TBD>

Win 8.1 Timers

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