| | | | | | | | | | | | | | | | | | | | | | | | | | | | For new stepping of PCH, the display reference clock is fully under driver's control. This one trys to setup all needed reference clock for different outputs. Older stepping of PCH chipset should be ignoring this.

| * drm/i915: Install a fence register for fbc on g4xChris Wilson2009-10-151-3/+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.

Border should be used when in VGA centered (un-scaled) mode or when scaling a 4:3 source image to a wide screen panel (typical 16:9). So when the LVDS scaling is used, decide whether the LVDS_BORDER should be enabled or not according to the current scaling mode.

* | i915: fix intel graphics suspend breakage due to resume/lid event confusionLinus Torvalds2009-11-023-8/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we trigger a tracepoint for batch buffer submission, it is a reasonable assumption that we wish to also trace the batch buffer completion.
