* drm/radeon/dpm: resume fixes for some systemsAlex Deucher2014-06-023-5/+6
| | | | | | | | | | | | | | | | Setting the power state prior to restoring the display hardware leads to blank screens on some systems. Drop the power state set from dpm resume. The power state will get set as part of the mode set sequence. Also add an explicit power state set after mode set resume to cover PX and headless systems. bug: https://bugzilla.kernel.org/show_bug.cgi?id=76761 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/radeon: Resume fbcon lastDaniel Vetter2014-05-311-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So a few people complained that commit 177cf92de4aa97ec1435987e91696ed8b5023130 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Apr 1 22:14:59 2014 +0200 drm/crtc-helpers: fix dpms on logic which was merged into 3.15-rc1, broke resume on radeons. Strangely git bisect lead everyone to commit 25f397a429dfa43f22c278d0119a60a343aa568f Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jul 19 18:57:11 2013 +0200 drm/crtc-helper: explicit DPMS on after modeset which was merged long ago and actually part of 3.14. Digging deeper I've noticed (again) that the call to drm_helper_resume_force_mode in the radeon resume handlers was a no-op previously because everything gets shut down on suspend. radeon does this with explicit calls to drm_helper_connector_dpms with DPMS_OFF. But with 177c we now force the dpms state to ON, so suddenly resume_force_mode actually forced the crtcs back on. This is the intention of the change after all, the problem is that radeon resumes the fbdev console layer _before_ restoring the display, through calling fb_set_suspend. And fbcon does an immediate ->set_par, which in turn causes the same forced mode restore to happen. Two concurrent modeset operations didn't lead to happiness. Fix this by delaying the fbcon resume until the end of the readeon resum functions. v2: Fix up a bit of the spelling fail.
