drm/i915/gvt: Disable access to stolen memory as a guest

2017-05-25T13:46:30Z

commit 04a68a35ce6d7b54749989f943993020f48fed62 upstream. Explicitly disable stolen memory when running as a guest in a virtual machine, since the memory is not mediated between clients and reserved entirely for the host. The actual size should be reported as zero, but like every other quirk we want to tell the user what is happening.

drm/edid: Add 10 bpc quirk for LGD 764 panel in HP zBook 17 G2

2017-05-25T13:46:29Z

commit e345da82bd6bdfa8492f80b3ce4370acfd868d95 upstream. The builtin eDP panel in the HP zBook 17 G2 supports 10 bpc, as advertised by the Laptops product specs and verified via injecting a fixed edid + photometer measurements, but edid reports unknown depth, so drivers fall back to 6 bpc. Add a quirk to get the full 10 bpc.

drm/nouveau/tmr: handle races with hw when updating the next alarm time

2017-05-25T13:46:15Z

commit 1b0f84380b10ee97f7d2dd191294de9017e94d1d upstream. If the time to the next alarm is short enough, we could race with HW and end up with an ~4 second delay until it triggers. Fix this by checking again after we update HW. Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman

drm/nouveau/tmr: avoid processing completed alarms when adding a new one

2017-05-25T13:46:15Z

commit 330bdf62fe6a6c5b99a647f7bf7157107c9348b3 upstream. The idea here was to avoid having to "manually" program the HW if there's a new earliest alarm. This was lazy and bad, as it leads to loads of fun races between inter-related callers (ie. therm). Turns out, it's not so difficult after all. Go figure ;) Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman

drm/nouveau/tmr: fix corruption of the pending list when rescheduling an alarm

2017-05-25T13:46:15Z

commit 9fc64667ee48c9a25e7dca1a6bcb6906fec5bcc5 upstream. At least therm/fantog "attempts" to work around this issue, which could lead to corruption of the pending alarm list. Fix it properly by not updating the timestamp without the lock held, or trying to add an already pending alarm to the pending alarm list....

drm/nouveau/tmr: ack interrupt before processing alarms

2017-05-25T13:46:15Z

commit 3733bd8b407211739e72d051e5f30ad82a52c4bc upstream. Fixes a race where we can miss an alarm that triggers while we're already processing previous alarms. Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman

drm/nouveau/kms/nv50: skip core channel cursor update on position-only changes

2017-05-25T13:46:15Z

commit e6db95799b1b870aae15682a6d0898df9e9dfb38 upstream. The DRM core used to only call prepare_fb/cleanup_fb() when a plane's framebuffer changed, which achieved the desired effect. It's apparently now up to the driver to decide on its own. Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman

drm/nouveau/kms/nv50: fix source-rect-only plane updates

2017-05-25T13:46:15Z

commit 36601c2b36e27435d9be33cfa092120ff69914eb upstream. This "optimisation" (which was originally meant to skip updating cursor settings in the core channel on position-only updates) turned out to be pointless in the final design of the code before it was merged. Remove it completely, as it breaks other cases. Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman

drm/nouveau/therm: remove ineffective workarounds for alarm bugs

2017-05-25T13:46:14Z

commit e4311ee51d1e2676001b2d8fcefd92bdd79aad85 upstream. These were ineffective due to touching the list without the alarm lock, but should no longer be required. Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: Add missing lb_vblank_lead_lines setup to DCE-6 path.

2017-05-25T13:46:14Z

commit effaf848b957fbf72a3b6a1ad87f5e031eda0b75 upstream. This apparently got lost when implementing the new DCE-6 support and would cause failures in pageflip scheduling and timestamping. Signed-off-by: Mario Kleiner Cc: Alex Deucher Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman
