- bios: unable to locate usable image

drm: Rework attach/detach and deferred task logic.

- Reduce the number of states the softc can be in.
- Fix races between attach and other threads.

drm: Omit needless pci_attach_args from our drm_pci_attach.

Can already get it from the struct pci_dev, and this way we can more
easily call it from patched upstream code as i915 will need to do.

drm: Remove local diffs for drm_pci_set_busid.

Instead, move it to its own file that can be safely used without
bringing in a link/run-time dependency on pci.

nouveau: Call nouveau_drm_device_init.

don't attach to new turing based nouveau cards.

this works well enough to start and have basic accel only on GTX 750,
so enable those cards. maybe can enable some pascal cards too.

thanks to fly for fixing nouveau drm2 so it was worth trying :-)

Move nouveau pci initialization to nouveau_pci where it belongs.

Somehow I forgot this was a separate module.

Clarify nvkm_device_pci_create arguments. Use bogus parent for match prints.

Let upstream code attempt match for nouveau.

Call linux_pci_dev_destroy on detach.

Pass the parent explicitly to linux_pci_dev_init.

This will allow us to use it in match routines.

Move linux_pci_dev_init into callers of drm_pci_attach.

The order in nouveau has to be

- linux_pci_dev_init
- nvkm_device_pci_new
- rest of drm_pci_attach

Nix vestigial temporary.

the previous change doubled the check for pascal. fix it so
that we only check for later maxwell and pascal once each,
as intended.

disable matching nouveau on pascal and the second generation of maxwell
cards that are not supported by this version of drm.

this should fix various modern systems vs nvidia issues, eg PR 53188.

XXX: pullup-7, pullup-8.

disable drm2 on modern nouveau cards (Pascal-based).

our older drm doesn't have any support for modern Pascal or
the second version of Maxwell (but not disabled here yet)
but the driver tries to attach on any nvidia gpu.

this should workaround PR#53258, and other issues reported
with modern nvidia chipsets.

(if i hack my nouveau to ignore fireware failure, it end up having
a vaguely working console and slowly working X, which is better than
the current situation.)

Pass a sensible device state pointer to nouveau suspend/resume ops.

Gives nouveau half a chance of suspending and resuming -- not that it
works on my test laptop yet, but it's a start.

push the real attach down via config_mountroot, like radeon, as we
need firmware files.. which are currently missing:
