2009-11-25drm/i915: Fix CRT hotplug detect by checking really no channels attachedZhenyu Wang
For CRT hotplug detect status, we have four test results as blue channel only, green channel only, both blue and green channel, and no channel attached. Origin code only marks both blue and green channel case as connected, but ignore other possible connected states. This one trys to detect CRT by checking no channel attached case instead.

2009-11-02i915: fix intel graphics suspend breakage due to resume/lid event confusionLinus Torvalds
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 Wilson
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.

2009-09-29drm/i915: Enable irq to trace batch buffer completion.Chris Wilson
If we trigger a tracepoint for batch buffer submission, it is a reasonable assumption that we wish to also trace the batch buffer completion.

2009-09-25drm/kms: start adding command line interface using fb.Dave Airlie
[note this requires an fb patch posted to linux-fbdev-devel already] This uses the normal video= command line option to control the kms output setup at boot time. It is used to override the autodetection done by kms. video= normally takes a framebuffer as the first parameter, in kms it will take a connector name, DVI-I-1, or LVDS-1 etc. If no output connector is specified the mode string will apply to all connectors. The mode specification used will match down the probed modes, and if no mode is found it will add a CVT mode that matches. video=1024x768 - all connectors match a 1024x768 mode or add a CVT on video=VGA-1:1024x768, VGA-1 connector gets mode only. The same strings as used in current fb modedb.c are used, except I've added three more letters, e, D, d, e = enable, D = enable Digital, d = disable, which allow a connector to be forced into a certain state.
