drm: disable all the possible outputs/crtcs before entering KMS mode

2010-01-06T23:04:53Z

commit b16d9acbdb97452d1418420e069acf7381ef10bb upstream. Sometimes we will use a crtc for integerated LVDS, which is different with that assigned by BIOS. If we want to get flicker-free transitions, then we could read out the current state for it and set our current state accordingly. But it is true that if we aren't reading current state out, we do need to turn everything off before modesetting. Otherwise the clocks can get very angry and we get things worse than a flicker at boot. In fact we also do the similar thing in UMS mode. We will disable all the possible outputs/crtcs for the first modesetting. So we disable all the possible outputs/crtcs before entering the KMS mode. Before we configure connector/encoder/crtc, the function of drm_helper_disable_unused_function can disable all the possible outputs/crtcs.

drm/radeon/kms: fix crtc vblank update for r600

2010-01-06T23:04:51Z

In 2.6.32.2 r600 had no IRQ support, however the patch in 500b758725314ab1b5316eb0caa5b0fa26740e6b to fix vblanks on avivo cards, needs irqs. So check for an R600 card and avoid this path if so. This is a stable only patch for 2.6.32.2 as 2.6.33 has IRQs for r600. Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

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.
