drm/i915: Fix LVDS stability issue on Ironlake

2009-12-18T22:05:48Z

commit 1b3c7a47f993bf9ab6c4c7cc3bbf5588052b58f4 upstream. In disable sequence, all output ports on PCH have to be disabled before PCH transcoder, but LVDS port was left always enabled. This one fixes that by disable LVDS port properly during pipe disable process, and resolved stability issue seen on Ironlake. Also move panel fitting disable time just after pipe disable to align with the spec. Signed-off-by: Zhenyu Wang Signed-off-by: Eric Anholt Signed-off-by: Greg Kroah-Hartman

drm/i915: Avoid NULL dereference with component_only tv_modes

2009-12-18T22:05:44Z

commit d271817baecbccb47da0d9f28c285a0dae8a06b7 upstream. In commit d2d9f2324, the guard for a valid video mode was removed. This caused the regression: kernel crash during kms graphic boot on Intel GM4500 platform https://bugzilla.redhat.com/show_bug.cgi?id=540218 This patches changes the logic slightly not to rely on a coupled variable, but to just check whether the video_modes is valid before dereferencing.

drm/i915: Fix sync to vblank when VGA output is turned off

2009-12-18T22:05:26Z

commit 778c902640530371a169ad1c03566e7c51b09874 upstream In current vblank-wait implementation, if we turn off VGA output, drm_wait_vblank will still wait on the disabled pipe until timeout, because vblank on the pipe is assumed be enabled. This would cause slow system response on some system such as moblin. This patch resolve the issue by adding a drm helper function drm_vblank_off which explicitly clear vblank_enabled[crtc], wake up any waiting queue and save last vblank counter before turning off crtc. It also slightly change drm_vblank_get to ensure that we will will return immediately if trying to wait on a disabled pipe.
