drm/udl: Use unlocked gem unreferencing

2016-04-30T22:06:07+00:00

commit 72b9ff0612ad8fc969b910cd00ac16b57a1a9ba4 upstream.

For drm_gem_object_unreference callers are required to hold
dev->struct_mutex, which these paths don't. Enforcing this requirement
has become a bit more strict with

drm/dp: move hw_mutex up the call stack

2016-04-30T22:06:07+00:00

commit 7779c5e23c5132c22a219f1f5554ef81dd15ee91 upstream.

1) don't let other threads trying to bang on aux channel interrupt the
defer timeout/logic
2) don't let other threads interrupt the i2c over aux logic

Technically, according to people who actually have the DP spec, this
should not be required.  In practice, it makes some troublesome Dell
monitor (and perhaps others) work, so probably a case of "It's compliant
if it works with windows" on the hw vendor's part..

v2: rebased to come before DPCD/AUX logging patch for easier backport
to stable branches.

Limit them for now.

drm/radeon: Don't drop DP 2.7 Ghz link setup on some cards.

2016-04-30T22:05:56+00:00

commit 459ee1c3fd097ab56ababd8ff4bb7ef6a792de33 upstream.

As observed on Apple iMac10,1, DCE-3.2, RV-730,
link rate of 2.7 Ghz is not selected, because
the args.v1.ucConfig flag setting for 2.7 Ghz
gets overwritten by a following assignment of
the transmitter to use.

Move link rate setup a few lines down to fix this.
In practice this didn't have any positive or
negative effect on display setup on the tested
iMac10,1 so i don't know if backporting to stable
makes sense or not.

commit 4807c5a8a0c87a210c36e3ad74c451a909d88588 upstream.

Some PX laptops seems to have problems turning the dGPU on/off.
Add a quirk list to disable runpm by default on those systems.
Also convert the current PX d3 delay handling to a quirk.

drm/radeon: hold reference to fences in radeon_sa_bo_new (3.17 and older)

2016-04-11T09:03:32+00:00

commit f6ff4f67cdf8455d0a4226eeeaf5af17c37d05eb upstream.

An arbitrary amount of time can pass between spin_unlock and
radeon_fence_wait_any, so we need to ensure that nobody frees the
fences from under us.

Based on the analogous fix for amdgpu.

 Backport of upstream commit f6ff4f67cdf8455d0a4226eeeaf5af17c37d05eb, with
 an additional NULL pointer guard that is required for kernels 3.17 and older.

 To be precise, any kernel that does *not* have commit 954605ca3 "drm/radeon:
