2009-11-25ACPICA: Add post-order callback to acpi_walk_namespaceLin Ming1-1/+1
The existing interface only has a pre-order callback. This change adds an additional parameter for a post-order callback which will be more useful for bus scans. ACPICA BZ 779.

2009-11-18drm: Add async event synchronization for drmWaitVblankKristian Høgsberg1-0/+1
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.

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.

2009-11-06drm/i915: implement drmmode overlay support v4Daniel Vetter7-3/+1361
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.

2009-11-06drm/i915: add i915_lp_ring_sync helperDaniel Vetter2-10/+40
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.

2009-11-02i915: fix intel graphics suspend breakage due to resume/lid event confusionLinus Torvalds3-8/+24
In commit c1c7af60892070e4b82ad63bbfb95ae745056de0 ("drm/i915: force mode set at lid open time") the intel graphics driver was taught to restore the LVDS mode on lid open. That caused problems with interaction with the suspend/resume code, which commonly runs at the same time (suspend is often caused by the lid close event, while lid open is commonly a resume event), which was worked around with in commit 06891e27a9b5dba5268bb80e41a283f51335afe7 ("drm/i915: fix suspend/resume breakage in lid notifier"). However, in the meantime the lid event code had also grown a user event notifier (commit 06324194eee97a51b5f172270df49ec39192d6cc: "drm/i915: generate a KMS uevent at lid open/close time"), and now _that_ causes problems with suspend/resume and some versions of Xorg reacting to those uevents by setting the mode. So this effectively reverts that commit 06324194ee, and makes the lid open protection logic against suspend/resume more explicit. This fixes at least one laptop. See http://bugzilla.kernel.org/show_bug.cgi?id=14484 for more details.

2009-10-15drm/i915: Install a fence register for fbc on g4xChris Wilson1-3/+5
To enable framebuffer compression on a g4x, we not only need the buffer to tiled (X only), we also need to hold a fence register for the buffer. Currently we only install a fence register for pre-i965s when setting up the scanout buffer. Rather than adding some convoluted logic to g4x_enable_fbc() to acquire a fence register, and perhaps to g4x_disable_fbc() to release it again, we can extend the acquisition during setup to all chipsets.
