Some BIOSes fail to initialise the GTT, which will cause DMA faults when the IOMMU is enabled. We need to clear the whole thing to point at the scratch page, not just the part that Linux is going to use. Signed-off-by:

These are handled by the error return being propagated to user-space and do not any add any information to the original error, so are useless. Signed-off-by:

If we don't detect a supported memory configuration, we can't enable CxSR. Warn the user in this case so they can file a bug.

This patch brings the tree up to date with some fixes that were in a more recent version of the page flipping patch you applied. It fixes pre-965 flip support, removes a leftover hack that forced alignment, and initializes the pipe & plane CRTC mappings. Signed-off-by:

This is a sync of a fix I made in the old UMS code. If the BIOS uses the GMBUS and doesn't clear that setup, then our bit-banging I2C can fail, leading to monitors not being detected. Signed-off-by: -

Without this, on some boots the TV wouldn't be detected. Testing showed 15ms to be insufficient. https://bugs.freedesktop.org/show_bug.cgi?id=24290 https://bugs.freedesktop.org/show_bug.cgi?id=20785Signed-off-by:

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. Signed-off-by:

Otherwise, I'd get stuck in a loop where (afaict) output scan would trigger a TV interrupt, which would trigger a scan, etc. TV load detection not being the fastest thing in the world, X would process requests very slowly. https://bugs.freedesktop.org/show_bug.cgi?id=24404Signed-off-by:

Only update the render-clock on transition from busy to idle and vice versa, or else we burn a significant percentage of the cpu just rewriting the register -- not quite as power-friendly as intended ;-) Signed-off-by:

We don't actually know which frame number the flip will complete on, so userspace needs a specific flip notification to tell it when the last flip completed. Signed-off-by:

On some laptops there is no HDMI/DP. But the xrandr still reports several disconnected HDMI/display ports. In such case the user will be confused. >DVI1 disconnected (normal left inverted right x axis y axis) >DP1 disconnected (normal left inverted right x axis y axis) >DVI2 disconnected (normal left inverted right x axis y axis) >DP2 disconnected (normal left inverted right x axis y axis) >DP3 disconnected (normal left inverted right x axis y axis) This patch set is to use the child device parsed in VBT to decide whether the HDMI/DP/LVDS/TV should be initialized. Parse the child device from VBT. The device class type is also added for LFP, TV, HDMI, DP output. https://bugs.freedesktop.org/show_bug.cgi?id=22785Signed-off-by:

if no VBT is present, crt_ddc_bus will be left at 0, and cause us to use that for the GPIO register offset. That's never a valid register offset, so let the "undefined" value be 0 instead of -1. Signed-off-by:

In commit d2d9f232, 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.

When switching to interruptible sleeps in the overlay code, I've forgotten to recover from interruptions at one site. This resulted in the overlay still running when it should have been switched off. This in turn caused a hang on resume because it tried to disable the (not-running) overlay in preparation for the resume modeset.

20ms delay is quite big and the routine isn't called in atomic context. better use msleep to let other tasks run. This can reduce cpu time used by Xorg, so potentially boost boot. Signed-off-by:

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:

The DPLL calculation logic for 9xx platform is changed in: commit 652c393a Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Mon Aug 17 13:31:43 2009 -0700 drm/i915: add dynamic clock frequency control Maybe we will get the different M/N/P combination with that by using the previous dpll calculation logic. So restore the DPLL calculation logic for 9xx platform. Signed-off-by:
