drm/i915: handle 3rd pipe

commit 07c1e8c1462fa7324de4c36ae9e55da2abd79cee upstream. We don't need to check 3rd pipe specifically, as it shares PLL with some other one.

drm/i915: Fix TV Out refresh rate.

2012-02-13T19:06:09+00:00

commit 23bd15ec662344dc10e9918fdd0dbc58bc71526d upstream. TV Out refresh rate was half of the specification for almost all modes. Due to this reason pixel clock was so low for some modes causing flickering screen.

drm/i915: check ACTHD of all rings

2012-02-13T19:06:09+00:00

commit 097354eb14fa94d31a09c64d640643f58e4a5a9a upstream. Otherwise hangcheck spuriously fires when running blitter/bsd-only workloads. Contrary to a similar patch by Ben Widawsky this does not check INSTDONE of the other rings. Chris Wilson implied that in a failure to detect a hang, most likely because INSTDONE was fluctuating. Thus only check ACTHD, which as far as I know is rather reliable. Also, blitter and bsd rings can't launch complex tasks from a single instruction (like 3D_PRIM on the render with complex or even infinite shaders). This fixes spurious gpu hang detection when running tests/gem_hangcheck_forcewake on snb/ivb.

drm/i915: DisplayPort hot remove notification to audio driver

2012-02-13T19:06:08+00:00

commit 832afda6a7d7235ef0e09f4ec46736861540da6d upstream. On DP monitor hot remove, clear DP_AUDIO_OUTPUT_ENABLE accordingly, so that the audio driver will receive hot plug events and take action to refresh its device state and ELD contents. Note that the DP_AUDIO_OUTPUT_ENABLE bit may be enabled or disabled only when the link training is complete and set to "Normal". Tested OK for both hot plug/remove and DPMS on/off.

drm/i915: HDMI hot remove notification to audio driver

2012-02-13T19:06:08+00:00

commit 2deed761188d7480eb5f7efbfe7aa77f09322ed8 upstream. On HDMI monitor hot remove, clear SDVO_AUDIO_ENABLE accordingly, so that the audio driver will receive hot plug events and take action to refresh its device state and ELD contents. The cleared SDVO_AUDIO_ENABLE bit needs to be restored to prevent losing HDMI audio after DPMS on.

drm/radeon/kms: disable output polling when suspended

drm/nouveau/gem: fix fence_sync race / oops

2012-02-13T19:06:07+00:00

commit 525895ba388c949aa906f26e3ec5cb1ab041f56b upstream. Due to a race it was possible for a fence to be destroyed while another thread was trying to synchronise with it. If this happened in the fallback non-semaphore path, it lead to the following oops due to fence->channel being NULL.

drm/radeon: Set DESKTOP_HEIGHT register to the framebuffer (not mode) height.

2012-02-13T19:06:07+00:00

commit 1b61925061660009f5b8047f93c5297e04541273 upstream. The value of this register is transferred to the V_COUNTER register at the beginning of vertical blank. V_COUNTER is the reference for VLINE waits and goes from VIEWPORT_Y_START to VIEWPORT_Y_START+VIEWPORT_HEIGHT during scanout, so if VIEWPORT_Y_START is not 0, V_COUNTER actually went backwards at the beginning of vertical blank, and VLINE waits excluding the whole scanout area could never finish (possibly only if VIEWPORT_Y_START is larger than the length of vertical blank in scanlines). Setting DESKTOP_HEIGHT to the framebuffer height should prevent this for any kind of VLINE wait. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=45329 .

vmwgfx: Fix assignment in vmw_framebuffer_create_handle

2012-02-03T17:19:00+00:00

commit bf9c05d5b6d19b3e4c9fe21047694e94f48db89b upstream. The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.
