drm/doc: Rename docbook to gpu.tmpl
DRM is a lot more than a direct rendering manager nowadays, and there's
also a bunch of things worth documenting for gpu driver developers
outside of drivers/gpu/drm, like vgaarb, vga_switcheroo or the various
hardware buses like host1x and ipu-v3.
To avoid further confusion let's rename the top-level to reflect
reality.
And yes I'm already looking forward to when we need to replace the G
in GPU with a * ;-)
Inspired by a thread with Lukas since he refused to include the
vga_switcheroo docs into the drm docs because it's not drm.

drm/i915: Move skl/bxt gt specific workarounds to ring init
Some registers are, naturally, lost in gpu reset/suspend cycle.
And some registers, for example in display domain, are not subject
to gpu reset so they retain their contents.
As hang recovery triggers a reset, recoverable gpu hang can currently
flush out essential workarounds and cause havoc later on.
When register GEN8_GARBNTL is missing the WaEnableGapsTsvCreditFix:skl,
it can cause random system hangs [1]. This workaround was added in:
commit 245d96670d26 ("drm/i915:skl: Add WaEnableGapsTsvCreditFix")
But another set of system hangs were observed and the failure pattern
indicated that there was random gpu hang preceding the system hang [2].
This lead to the realization that we lose this workaround and BDW_SCRATCH1
on reset.
Add these workarounds setup in display init to skl/bxt ring init
where LRI workarounds are also setup. This way their setup is not
dependent on display side init.

drm/i915: Drop i915_gem_obj_is_pinned() from set-cache-level
Since the remove of the pin-ioctl, we only care about not changing the
cache level on buffers pinned to the hardware as indicated by
obj->pin_display. By knowing that only objects pinned to the hardware
will have an elevated vma->pin_count, so we can coallesce many of the
linear walks over the obj->vma_list.
v2: Try and retrospectively add comments explaining the steps in
rebinding the active VMA.

seems that this commit prevents the machine from completely freezing

drm/i915: Hold dev->event_lock whilst inspecting intel_crtc->unpin_work
We should serialise access to the intel_crtc->unpin_work through the
dev->event_lock spinlock. It should not be possible for it to disappear
without severe error as the mmio_flip worker has not tagged the
unpin_work pending flip-completion. Similarly if the error exists, just
taking the unpin_work whilst holding the spinlock and then using it
unserialised just masks the race. (It is supposed to be valid as the
unpin_work exists until the flip completion interrupt which should not
fire until we flush the mmio writes to update the display base which is
the last time we access the unpin_work from the kthread.)

drm/nouveau/bios: fix OF loading
Currently OF bios load fails for a few reasons:
- checksum failure
- bios size too small
- no PCIR header
- bios length not a multiple of 4
In this change, we resolve all of the above by ignoring any checksum
failures (since OF VBIOS tends not to have a checksum), and faking the
PCIR data when loading from OF.

drm/nouveau/fbcon: take runpm reference when userspace has an open fd
We need to do this in order to prevent accesses to the device while it's
powered down. Userspace may have an mmap of the fb, and there's no good
way (that I know of) to prevent it from touching the device otherwise.
This fixes some nasty races between runpm and plymouth on some systems,
which result in the GPU getting very upset and hanging the boot.

SiS 761 chipset does not support AGP cards but has AGP capability (for

an AGP-like AGPro slot that's wired to the PCI bus. Enabling AGP will
fail (GPU lockup and software fbcon, X11 hangs).
