Change return value to int to propagate errors from gamma_set,
and remove start parameter. Updates always use the full size,
and some drivers even ignore the start parameter altogether.
This is needed for atomic drivers, where an atomic commit can
fail with -EINTR or -ENOMEM and should be restarted. This is already
and issue for drm_atomic_helper_legacy_set_gamma, which this patch
fixes up.
Changes since v1:
- Fix compiler warning. (Emil)

Nothing too exciting here, there's a larger chunk of work that still
needs more testing but not likely to get that done today - so - here's
the rest of it. Assuming nothing else goes horribly wrong, I should be
able to send the rest Monday if it isn't too late....
Changes:
- Improvements to power sensor support
- Initial attempt at GM108 support
- Minor fixes to GR init + ucode
- Make use of topology information (provided by the GPU) in various
places, should at least fix some fault recovery issues and
engine/runlist mapping confusion on newer GPUs.

drm_gem_object_lookup() has never required the drm_device for its file
local translation of the user handle to the GEM object. Let's remove the
unused parameter and save some space.

I want to remove the core ones since with atomic drivers system
suspend/resume is solved much differently. And there's only 2 drivers
(gma500 besides nouveau) really using them.

The namespace of NVKM is being changed to nvkm_ instead of nouveau_,
which will be used for the DRM part of the driver. This is being
done in order to make it very clear as to what part of the driver a
given symbol belongs to, and as a minor step towards splitting the
DRM driver out to be able to stand on its own (for virt).
Because there's already a large amount of churn here anyway, this is
as good a time as any to also switch to NVIDIA's device and chipset
naming to ease collaboration with them.
A comparison of objdump disassemblies proves no code changes.

NVKM is having it's namespace switched to nvkm_, which will conflict
with these functions (which are workarounds for the fact that as of
yet, we still aren't able to split DRM and NVKM completely).

Rename to match the Linux subsystem responsible for the same kind of

GPU clock trees with it at some point.

We have the ability to move buffers around in the kernel if necessary,
and should probably use it rather than failing if userspace passes us
a non-contig buffer for a plane.
The NOUVEAU_GEM_TILE_NONCONTIG flag from userspace will become a mere
initial placement hint once all the relevant paths have been updated.

Just a bit of OCD cleanup on headers - this function isn't the core
interface any more but just a helper for drivers who haven't yet
transitioned to universal planes. Put the declaration at the right
spot and sprinkle necessary #includes over all drivers.
Maybe this helps to encourage driver maintainers to do the switch.
v2: Fix #include ordering for tegra, reported by 0-day builder.
v3: Include required headers, reported by Thierry.

Now that CRTC's have a primary plane, there's no need to track the
framebuffer in the CRTC. Replace all references to the CRTC fb with the
primary plane's fb.
This patch was generated by the Coccinelle semantic patching tool using
the following rules:
@@ struct drm_crtc C; @@
- (C).fb
+ C.primary->fb
@@ struct drm_crtc *C; @@
- (C)->fb
+ C->primary->fb
v3: Generate patch via coccinelle. Actual removal of crtc->fb has been
moved to a subsequent patch.
v2: Fixup several lingering crtc->fb instances that were missed in the
first patch iteration. [Rob Clark]

This hooks nouveau up to the runtime PM system to enable
dynamic power management for secondary GPUs in switchable
and optimus laptops.
a) rewrite suspend/resume printks to hide them during dynamic s/r
to avoid cluttering logs
b) add runtime pm suspend to irq handler, crtc display, ioctl handler,
connector status,
c) handle hdmi audio dynamic power on/off using magic register.
v0.5:
make sure we hit D3 properly
fix fbdev_set_suspend locking interaction, we only will poweroff if we have no
active crtcs/fbcon anyways.
add reference for active crtcs.
sprinkle mark last busy for autosuspend timeout
v0.6:
allow more flexible debugging - to avoid log spam
add option to enable/disable dynpm
got to D3Cold
v0.7:
add hdmi audio support.
v0.8:
call autosuspend from idle, so pci config space access doesn't go straight
back to sleep, this makes starting X faster.
only signal usage if we actually handle the irq, otherwise usb keeps us awake.
fix nv50 display active powerdown
v0.9:
use masking function to enable hdmi audio
set busy when we fail to suspend

It'd be pretty awesome if someone would care enough to port this all
properly to a class interface, perhaps submitting a command stream to
the core via a sw object on PFIFO (emulating how EVO works basically,
and also what nvidia have done forever..)..
But, this seems unlikely given how old this hardware is now, so, lets
just hide it away.
There's a heap of other bits and pieces laying around that are still
tangled. I'll (re)move them in pieces.
