drm/i915/glk: Add Quirk for GLK NUC HDMI port issues.

2018-10-20T07:48:53+00:00

commit 0ca9488193e61ec5f31a631d8147f74525629e8a upstream. On GLK NUC platforms the HDMI retiming buffer needs additional disabled time to correctly sync to a faster incoming signal. When measured on a scope the highspeed lines of the HDMI clock turn off for ~400uS during a normal resolution change. The HDMI retimer on the GLK NUC appears to require at least a full frame of quiet time before a new faster clock can be correctly sync'd. Wait 100ms due to msleep inaccuracies while waiting for a completed frame. Add a quirk to the driver for GLK boards that use ITE66317 HDMI retimers. V2: Add more devices to the quirk list V3: Delay increased to 100ms, check to confirm crtc type is HDMI. V4: crtc type check extended to include _DDI and whitespace fixes v5: Fix white spaces, remove the macro for delay. Revert the crtc type check introduced in v4.

drm/i915: Nuke the LVDS lid notifier

2018-10-20T07:48:53+00:00

commit 05c72e77ccda89ff624108b1b59a0fc43843f343 upstream. We broke the LVDS notifier resume thing in (presumably) commit e2c8b8701e2d ("drm/i915: Use atomic helpers for suspend, v2.") as we no longer duplicate the current state in the LVDS notifier and thus we never resume it properly either. Instead of trying to fix it again let's just kill off the lid notifier entirely. None of the machines tested thus far have apparently needed it. Originally the lid notifier was added to work around cases where the VBIOS was clobbering some of the hardware state behind the driver's back, mostly on Thinkpads. We now have a few report of Thinkpads working just fine without the notifier. So maybe it was misdiagnosed originally, or something else has changed (ACPI video stuff perhaps?). If we do end up finding a machine where the VBIOS is still causing problems I would suggest that we first try setting various bits in the VBIOS scratch registers. There are several to choose from that may instruct the VBIOS to steer clear. With the notifier gone we'll also stop looking at the panel status in ->detect(). v2: Nuke enum modeset_restore (Rodrigo) Cc: stable@vger.kernel.org Cc: Wolfgang Draxinger Cc: Vito Caputo Cc: kitsunyan Cc: Joonas Saarinen Tested-by: Vito Caputo # Thinkapd X61s Tested-by: kitsunyan # ThinkPad X200 Tested-by: Joonas Saarinen # Fujitsu Siemens U9210 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105902 References: https://lists.freedesktop.org/archives/intel-gfx/2018-June/169315.html References: https://bugs.freedesktop.org/show_bug.cgi?id=21230 Fixes: e2c8b8701e2d ("drm/i915: Use atomic helpers for suspend, v2.")

drm: mali-dp: Call drm_crtc_vblank_reset on device init

2018-10-20T07:48:51+00:00

[ Upstream commit 69be1984ded00a11b1ed0888c6d8e4f35370372f ] Currently, if userspace calls drm_wait_vblank before the crtc is activated the crtc vblank_enable hook is called, which in case of malidp driver triggers some warninngs. This happens because on device init we don't inform the drm core about the vblank state by calling drm_crtc_vblank_on/off/reset which together with drm_vblank_get have some magic that prevents calling drm_vblank_enable when crtc is off.

drm/syncobj: Don't leak fences when WAIT_FOR_SUBMIT is set

2018-10-13T07:27:23+00:00

commit 337fe9f5c1e7de1f391c6a692531379d2aa2ee11 upstream. We attempt to get fences earlier in the hopes that everything will already have fences and no callbacks will be needed. If we do succeed in getting a fence, getting one a second time will result in a duplicate ref with no unref. This is causing memory leaks in Vulkan applications that create a lot of fences; playing for a few hours can, apparently, bring down the system.

drm/amdgpu: Fix vce work queue was not cancelled when suspend

2018-10-13T07:27:23+00:00

commit 61ea6f5831974ebd1a57baffd7cc30600a2e26fc upstream. The vce cancel_delayed_work_sync never be called. driver call the function in error path. This caused the A+A suspend hang when runtime pm enebled. As we will visit the smu in the idle queue. this will cause smu hang because the dgpu has been suspend, and the dgpu also will be waked up. As the smu has been hang, so the dgpu resume will failed.
