Ben Skeggs 835aadbef3 drm/nv50: send evo "update" command after each disconnect
It turns out that the display engine signals an interrupt for disconnects
too.  In order to make it easier to process the display interrupts
correctly, we want to ensure we only get one operation per interrupt
sequence - this is what this commit achieves.

Ben Skeggs ec7fc4a1a7 drm/nv50: supply encoder disable() hook for SOR outputs
Allows us to remove a driver hack that used to be necessary to disable
encoders in certain situations before setting up a mode.  The DRM has
better knowledge of when this is needed than the driver does.

This fixes a number of display switching issues.

Luca Barbieri bc9025bdc4 Use drm_gem_object_[handle_]unreference_unlocked where possible
Mostly obvious simplifications.

The i915 pread/pwrite ioctls, intel_overlay_put_image and
nouveau_gem_new were incorrectly using the locked versions
without locking: this is also fixed in this patch.

Ben Skeggs 58d65b84de drm/nv50: prevent accidently turning off encoders we're actually using
On most cards the DisplayPort connector is created with 2 encoders sharing
a single SOR (for native DP, and for DVI-over-DP).  The previous logic
for turning off unused encoders didn't take into account that we could
have multiple drm_encoders on a single hw encoder and ended up turning off
encoders that were actually being used still.

This patch fixes that issue.  We probably want to look at something a bit
better later on, and only expose one drm_encoder per hw encoder block.

Maarten Maathuis ef2bb50668 drm/nouveau: use drm debug levels
- Use driver level (0x2) for NV_DEBUG instead of all levels
- Create a NV_DEBUG_KMS for KMS level (0x4) and use them in modesetting code
- Remove a few odd NV_TRACE calls and replace some of them with NV_DEBUG_KMS or
NV_INFO

Ben Skeggs 6ee738610f drm/nouveau: Add DRM driver for NVIDIA GPUs
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.

This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.

This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.

This driver is reverse engineered, and is in no way supported by nVidia.

Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.

This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.
