--- Comment #13 from John Baldwin <jhb at FreeBSD.org> ---
So my question is why does Linuxkpi care about the sleep state?  Does it
actually have conditional logic that it is using?  If it really needs it, then
what I think we should do is change DEVICE_SUSPEND/RESUME to add the type of
suspend/resume being requested.  This is somewhat complicated because devices
can be suspended and resumed not as part of a system wide suspend and resume
(e.g. 'devctl suspend foo0'), and for S0ix what you really want is to power
down devices that aren't used even if the system isn't fully idle itself.  So,
the first question is why does Linuxkpi care what the system sleep state is vs
what Dx state the GPU device is being placed in?
