* drm/radeon/kms: adjust quirk for acer laptopAlex Deucher2011-01-061-10/+11
| | | | | | | | | | | | | | | | | | | Acer laptop (TravelMate 5730G) has an HDMI connector on the laptop and a DVI connector on the docking station and both share the same encoder, hpd pin, and ddc line. The bios connector table reflects this and is technically correct, however, we drop the DVI connector here since xrandr has no concept of encoders (only crtcs and connectors) and will try and drive both connectors with different crtcs which isn't possible on the hardware side and leaves no crtcs for LVDS or VGA.

* drm/switcheroo: track state of switch in drivers.Dave Airlie2011-01-059-12/+35

| * drm/i915, intel_ips: When i915 loads after IPS, make IPS relink to i915.Eric Anholt2010-12-231-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The IPS driver is designed to be able to run detached from i915 and just not enable GPU turbo in that case, in order to avoid module dependencies between the two drivers. This means that we don't know what the load order between the two is going to be, and we had previously only supported IPS after (optionally) i915, but not i915 after IPS. If the wrong order was chosen, you'd get no GPU turbo, and something like half the possible graphics performance.

It detects if the pageflip completion routine gets executed before or after drm_handle_vblank, and thereby decides if the returned vblank count and timestamp must be incremented by 1 frame(duration) or not. It compares the current system time at invocation against the current vblank timestamp. If the difference is more than 0.9 video refresh interval durations then it assumes the vblank timestamp and count are outdated and need to be incremented and does so. Otherwise it assumes a delayed pageflip irq and doesn't correct the timestamp and count. Advantage of this patch: Pageflip timestamping becomes more robust against implementation errors and is maintenance free for future GPU's. Disadvantage: A few dozen (hundred?) nsecs extra time spent in pageflip irq handler for each flip, compared to hard-coded per-gpu settings?

It is a thin wrapper around the drm function drm_calc_vbltimestamp_from_scanoutpos() which does almost all the work. .get_scanout_position() provides the current horizontal and vertical video scanout position and "in vblank" status of a given crtc, as needed by the drm for use by drm_calc_vbltimestamp_from_scanoutpos(). The patch modifies the pageflip completion routine to use these precise vblank timestamps as the timestamps for pageflip completion events. This code has been only tested on a HP-Mini Netbook with Atom processor and Intel 945GME gpu. The codepath for (IS_G4X(dev) || IS_GEN5(dev) || IS_GEN6(dev)) gpu's has not been tested so far due to lack of hardware.
