2009-11-30drm/i915: parse child device from VBTZhao Yakui
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.

2009-11-30drm/i915: fixup interrupted overlay switch off callsDaniel Vetter
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.

2009-11-25drm/i915: Replace a calloc followed by copying data over it with malloc.Eric Anholt
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.

2009-11-05drm/i915: implement interruptible sleeps in the overlay codeDaniel Vetter
At least for the common case of userspace ioctls. When doing a modeset operation, the wait is still uninterruptible. But considering that failing to turn off the overlay when switching off the crtc it's running on hangs the chip, it doesn't complicate matters _very_ much.

2009-11-05drm/i915: implement drmmode overlay support v4Daniel Vetter
This implements intel overlay support for kms via a device-specific ioctl. Thomas Hellstrom brought up the idea of a general ioctl (on dri-devel). We've reached the conclusion that such an infrastructure only makes sense when multiple kms overlay implementations exists, which atm don't (and it doesn't look like this is gonna change). Open issues: - Runs in sync with the gpu, i.e. unnecessary waiting. I've decided to wait on this because the hw tends to hang when changing something in this area. I left some dummy functions as infrastructure. - polyphase filtering uses a static table. - uses uninterruptible sleeps. Unfortunately the alternatives may unnecessarily wedged the hw if/when we timeout too early (and userspace only overloaded the batch buffers with stuff worth a few secs of gpu time). Changes since v1: - fix off-by-one misconception on my side. This fixes fullscreen playback. Changes since v2: - add underrun detection as spec'ed for i965. - flush caches properly, fixing visual corruptions. Changes since v4: - fix up cache flushing of overlay memory regs. - killed require_pipe_a logic - it hangs the chip.

2009-11-05drm/i915: add i915_lp_ring_sync helperDaniel Vetter
This just waits until the hw passed the current ring position with cmd execution. This slightly changes the existing i915_wait_request function to make uninterruptible waiting possible - no point in returning to userspace while mucking around with the overlay, that piece of hw is just too fragile. Also replace a magic 0 with the symbolic constant (and kill the then superflous comment) while I was looking at the code.
