Anyone working on nvme power management?

[Andy Lutomirski]

It looks like the nvme spec allows both nvme-specific low power states
and D3.  Is anyone working on supporting either of these in the Linux
driver?

Also, the host memory buffer feature seems related, although I can't
find anything in the spec saying what its purpose is.  Is it related
to the power management features?  Does it give faster low-power
exits?
