[PATCH 00/14] drm/radeon: uvd/vce cleanup and fix for hibernation

[Jérôme Glisse]

So all patches does not change the logic or outcome (from hw register
write point of view) only what error messages get printed on failure.

Patch 13 just add a new flag to asic reset so we can force hard reset.

Patch 14 takes advantages of that for the hibernation case and hard
reset during freeze. It seems to works well for several hibernation
cycles (both real hibernation and also when using PM_DEBUG facilities).

All this was only test on southern island laptop (si), i did however
read over and over the various patches to check that i did not change
behavior. I splitted them for each asic generation to make bisection
easier in the unlikely case that i did miss something.

Please review.

Cheers,
Jérôme

[PATCH 01/14] drm/radeon: consolidate r600 uvd initialization and startup code.

[Jérôme Glisse]

From: Jérome Glisse <jglisse@redhat.com>

This match the exact same control flow as existing code. It just
use goto instead of multiple levels of if/else. It also clarify
early initialization failures by clearing rdev->has_uvd doing so
does not change end result from hardware point of view, it only
avoids printing more error messages down the line and thus only
the original error is reported.

[PATCH 02/14] drm/radeon: consolidate rv770 uvd initialization and startup code.

[Jérôme Glisse]

From: Jérome Glisse <jglisse@redhat.com>

This match the exact same control flow as existing code. It just
use goto instead of multiple levels of if/else. It also clarify
early initialization failures by clearing rdev->has_uvd doing so
does not change end result from hardware point of view, it only
avoids printing more error messages down the line and thus only
the original error is reported.

[PATCH 06/14] drm/radeon: consolidate cik uvd initialization and startup code.

[Jérôme Glisse]

From: Jérome Glisse <jglisse@redhat.com>

This match the exact same control flow as existing code. It just
use goto instead of multiple levels of if/else. It also clarify
early initialization failures by clearing rdev->has_uvd doing so
does not change end result from hardware point of view, it only
avoids printing more error messages down the line and thus only
the original error is reported.

[PATCH 10/14] drm/radeon: consolidate cik vce initialization and startup code.

[Jérôme Glisse]

From: Jérome Glisse <jglisse@redhat.com>

This match the exact same control flow as existing code. It just
use goto instead of multiple levels of if/else. It also clarify
early initialization failures by clearing rdev->has_vce doing so
does not change end result from hardware point of view, it only
avoids printing more error messages down the line and thus only
the original error is reported.

[PATCH 13/14] drm/radeon: allow to force hard GPU reset.

[Jérôme Glisse]

From: Jérome Glisse <jglisse@redhat.com>

In some cases, like when freezing for hibernation, we need to be
able to force hard reset even if no engine are stuck. This patch
add a bool option to current asic reset callback to allow to force
hard reset on asic that supports it.

[PATCH 14/14] drm/radeon: hard reset r600 and newer GPU when hibernating.

[Jérôme Glisse]

From: Jérome Glisse <jglisse@redhat.com>

Some GPU block like UVD and VCE require hard reset to be properly
resume if there is no real powerdown of the asic like during various
hibernation step. This patch perform such hard reset.
