[nvmewin] support for NVME DataSet Mgmt

[Kong, Kwok]

We decided not to implement any features that Windows 7 did not support at the time.

This is a feature that we can add this year once we add the support of Windows 8. I'll set up a meeting soon to discuss the features that we want to add to the driver this year.

It will be great if Samsung can contribute to the new features development.  This is a  joint effort and we need everyone to participate and contribute.

Please send out any features that you would like to add to the current driver.  I'll collect them all and set up a call to discuss.

I need all your help to improve the Windows driver.

Thanks

-Kwok

It's only because at the time Windows (storport) didn't support passing TRIM through to the miniport.  When we talked about the roadmap for this year, this is one of those items (and its small) now that Win8 and 2012 pass it through the driver can field it.  No specific date was determined though, as soon as someone contributes it, it will be there :)

Thx

Hello,

I was wondering why the driver doesn't support the SCSI Unmap command. The comment in SntiTranslateCommand() says:

" ...UNMAP (NVME_DATASET_MANAGEMENT is required for translation and this command will not be supported in the Windows open source driver)"

but the driver does in fact support NVMe dataset mgmnt - although the only path to it is by way of an NVMe IOCTL passthru. Was the IOCTL path perhaps added after the main SCSI translation path and is it the case that we would now want to add support for SCSI unmap/translation to DataSetMgmt?

Thanks,
Judy
