Ben Skeggs 3f196a045e drm/nve0: magic up some support for GF117
Seen in the wild, don't have the hardware but this hacks things up to
treat it the same as GF119 for now.

Should be relatively safe, I'd be very surprised if anything major
changed outside of PGRAPH.  PGRAPH (3D etc) is disabled by default
however until it's confirmed working.

Well it broke on my system too, so it was easy to fix.

Maarten Lankhorst b43decd2c5 drm/nouveau: fix handling empty channel list in ioctl's
If there are no channels, chan would never end up being NULL,
and so the null pointer check would fail.

Solve this by initializing chan to NULL, and iterating over temp instead.

Fixes oops when running intel-gpu-tools/tests/kms_flip, which attempts to

wouldn't be impacted by those waits too much.

Linus Torvalds fffddfd6c8 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm merge from Dave Airlie:
 "Highlights:

   - TI LCD controller KMS driver

   - TI OMAP KMS driver merged from staging

   - drop gma500 stub driver

   - the fbcon locking fixes

   - the vgacon dirty like zebra fix.

   - open firmware videomode and hdmi common code helpers

   - major locking rework for kms object handling - pageflip/cursor
     won't block on polling anymore!

   - fbcon helper and prime helper cleanups

   - i915: all over the map, haswell power well enhancements, valleyview
     macro horrors cleaned up, killing lots of legacy GTT code,

   - radeon: CS ioctl unification, deprecated UMS support, gpu reset
     rework, VM fixes

   - nouveau: reworked thermal code, external dp/tmds encoder support
     (anx9805), fences sleep instead of polling,

   - exynos: all over the driver fixes."

Lovely conflict in radeon/evergreen_cs.c between commit de0babd60d
("drm/radeon: enforce use of radeon_get_ib_value when reading user cmd")
and the new changes that modified that evergreen_dma_cs_parse()
function.

Nothing terribly exciting in here probably:
- reworked thermal stuff from mupuf/I, has a chance of possibly working
well enough when we get to being able to reclock..
- driver will report mmio access faults on chipsets where it's supported
- will now sleep waiting on fences on nv84+ rather than polling
- some cleanup of the internal fencing, looking towards sli/dmabuf sync
- initial support for anx9805 dp/tmds encoder
- nv50+ display fixes related to the above, and also might fix a few
other issues
- nicer error reporting (will log process names with channel errors)
- various other random fixes

Ben Skeggs 0a0afd282f drm/nv50-/disp: move DP link training to core and train from supervisor
We need to be able to do link training for PIOR-connected ANX9805 from
the third supervisor handler (due to script ordering in the bios, can't
have the "user" call train because some settings are overwritten from
the modesetting bios scripts).

This moves link training for SOR-connected DP encoders to the second
supervisor interrupt, *before* we call the modesetting scripts (yes,
different ordering from PIOR is necessary).  This is useful since we
should now be able to remove some hacks to workaround races between
the supervisor and link training paths.
