[PATCH] NVMe: Update SCSI Inquiry VPD 83 translation

[Zakaria Abushima (zabushima)]

Hi Guys,

Off the topic, I have read that namespace in nvme is equivalent to SCSI LUN

So how can I write application to create name spaces up to 32 from the userspace.

In other word is there any application to write SCSI LUN from userspace,

Also, it says that creating name space is a vendor specific ? how can the vendor find out the way to create a namespace ?

Any explanation or clarification ?

Please guide me because I'm completely lost.

Zakaria.

I think we want an NVME_VERSION() macro that maybe looks something like this:

#define NVME_VERSION(major, minor) (((major) << 16) | ((minor) << 8))

Then you can make this:

	if (readl(&dev->bar->vs) >= NVME_VERSION(1, 1))

What do you think?
