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:

Zhao Yakui authored
If more than one mode with the same resolution defined in EDID has different refresh rate, it is thought that the downclock is found for LVDS. We will program the different FPx0/1 register so that we can select dynamically between the low and high frequency. On the g4x platform we will use the CxSR feature to switch the different refresh rate if the LVDS downclock feature is supported. Signed-off-by:

Execbufs involve quite a bit of payload, to the extent that cache misses show up in the profiles here, and a suspicion that some of those cachelines may get evicted and then reloaded in the subsequent copy. This is still abstracted like drm_calloc_large since we want to check for size overflow, and because we want to choose between kmalloc and vmalloc on the fly. cairo's interface for malloc-with-calloc's-args was used as the model.

This adds a page flipping ioctl to the KMS API. The ioctl takes an fb ID and a ctrc ID and flips the crtc to the given fb at the next vblank. The ioctl returns immediately but the flip doesn't happen until after any rendering that's currently queued up against the new framebuffer is done. After submitting a page flip, any execbuffer involving the old front buffer will block until the flip is completed. Optionally, a vblank event can be generated when the swap eventually happens.

There are a few more macros in drmP.h that are unused; DRM_GET_PRIV_SAREA, DRM_ARRAY_SIZE, and DRM_WAITCOUNT can go away completely. Unfortunately, DRM_COPY is still used in one place, but we can at least move it to where it's used. It's an awful looking macro.. [akpm: fix overeagerness] Signed-off-by:

This patch adds a new flag to the drmWaitVblank ioctl, which asks the drm to return immediately and notify userspace when the specified vblank sequence happens by sending an event back on the drm fd. The event mechanism works with the other flags supported by the ioctls, specifically, the vblank sequence can be specified relatively or absolutely, and works for primary and seconday crtc. The signal field of the vblank request is used to provide user data, which will be sent back to user space in the vblank event. Signed-off-by:
