[PULL] drm-intel fixes&leftovers for 3.10

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Dave,

As promised a stash of (mostly) fixes. Two pieces of non-fixes included:
- A notch more gtt refactoring from Ben, beating to death with igt in our
  nightly testing.
- Support for display display-less server chips (again from Ben). New hw
  support which is only likely to break itself ;-)

Otherwise just tons of fixes:
- hpd irq storm mitigation from Egbert Eich. Your -next tree already has
  the infrastructure, this here just supplies the logic.
- sdvo hw state check fix from Egbert Eich
- fb cb tune settings for the pch pll clocks on cpt/ppt
- "Bring a bigger gun" coherence workaround for multi-threade, mulit-core
  & thrashing tiled gtt cpu access from Chris.
- Update haswell mPHY code.
- l3$ caching for context objects on ivb/hsw (Chris).
- dp aux refclock fix for haswell (Jani)
- moar overclocking fixes for snb/ivb (Ben)
- ecobits ppgtt pte caching control fixes from Ville
- fence stride check fixes and limit improvements (Ville)
- fix up crtc force restoring, potentially resulting in tons of hw state
  check WARNs
- OOPS fix for NULL derefencing of fb pointers when force-restoring a crtc
  when other crtcs are disabled and the force-restored crtc is _not_ the
  first one.
- Fix pfit disabling on gen2/3.
- Haswell ring freq scaling fixes (Chris).
- backlight init/teardown fix (failed eDP init killed the lvds backlight)
  from Jani
- cpt/ppt fdi polarity fixes from Paulo (should help a lot of the FDI link
  train failures).
- And a bunch of smaller things all over.

Cheers, Daniel

PS: Since I've already split out -next for 3.11, this pull is for the
-fixes branch.
