drm/nouveau: fix init with agpgart-uninorth

2013-01-16T01:13:18Z

commit eda85d6ad490923152544fba0473798b6cc0edf6 upstream. Check that the AGP aperture can be mapped. This follows a similar change done for Radeon (commit 365048ff, drm/radeon: AGP memory is only I/O if the aperture can be mapped by the CPU.). The patch fixes the following error seen on G5 iMac: nouveau E[ DRM] failed to create kernel channel, -12 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=58806 Reviewed-by: Michel Dänzer Signed-off-by: Aaro Koskinen Signed-off-by: Dave Airlie [bwh: Backported to 3.2: adjust context] Signed-off-by: Ben Hutchings

commit cafa59b9011a7790be4ddd5979419259844a165d upstream. Apple cards do not provide data tables in the vbios so we have to hard code the connector parameters in the driver. Reported-by: Albrecht Dreß Signed-off-by: Alex Deucher Signed-off-by: Ben Hutchings

i915: ensure that VGA plane is disabled

2013-01-16T01:13:11Z

commit 0fde901f1ddd2ce0e380a6444f1fb7ca555859e9 upstream. Some broken systems (like HP nc6120) in some cases, usually after LID close/open, enable VGA plane, making display unusable (black screen on LVDS, some strange mode on VGA output). We used to disable VGA plane only once at startup. Now we also check, if VGA plane is still disabled while changing mode, and fix that if something changed it.

drm/i915: do not default to 18 bpp for eDP if missing from VBT

2013-01-03T03:33:48Z

commit 9a30a61f3516871c5c638fd7c025fbaa11ddf7fe upstream. commit 500a8cc466a24e2fbc4c86ef9c6467ae2ffdeb0c Author: Zhenyu Wang Date: Wed Jan 13 11:19:52 2010 +0800 drm/i915: parse eDP panel color depth from VBT block originally introduced parsing bpp for eDP from VBT, with a default of 18 bpp if the eDP BIOS data block is not present. Turns out that default seems to break the Macbook Pro with retina display, as noted in commit 4344b813f105a19f793f1fd93ad775b784648b95 Author: Daniel Vetter Date: Fri Aug 10 11:10:20 2012 +0200 drm/i915: ignore eDP bpc settings from vbt Since we can't ignore bpc settings from VBT completely after all, get rid of the default. Do not clamp eDP to 18 bpp by default if the eDP BDB is missing from VBT.

drm/i915: do not ignore eDP bpc settings from vbt

2013-01-03T03:33:47Z

commit 2f4f649a69a9eb51f6e98130e19dd90a260a4145 upstream. There are laptops out there that need the eDP bpc from VBT. This is effectively a revert of commit 4344b813f105a19f793f1fd93ad775b784648b95 Author: Daniel Vetter Date: Fri Aug 10 11:10:20 2012 +0200 drm/i915: ignore eDP bpc settings from vbt but putting the VBT check after the EDID check to see them both in dmesg if this clamps more than the EDID. We have enough history with bpc clamping to warrant the extra debug info.

drm/i915: disable cpt phase pointer fdi rx workaround

2013-01-03T03:33:34Z

commit 539526b4137bc0e7a8806c38c8522f226814a0e6 upstream. We've originally added this in commit 291427f5fdadec6e4be2924172e83588880e1539 Author: Jesse Barnes Date: Fri Jul 29 12:42:37 2011 -0700 drm/i915: apply phase pointer override on SNB+ too and then copy-pasted it over to ivb/ppt. The w/a was originally added for ilk/ibx in commit 5b2adf897146edeac6a1e438fb67b5a53dbbdf34 Author: Jesse Barnes Date: Thu Oct 7 16:01:15 2010 -0700 drm/i915: add Ironlake clock gating workaround for FDI link training and fixed up a bit in commit 6f06ce184c765fd8d50669a8d12fdd566c920859 Author: Jesse Barnes Date: Tue Jan 4 15:09:38 2011 -0800 drm/i915: set phase sync pointer override enable before setting phase sync pointer It turns out that this w/a isn't actually required on cpt/ppt and positively harmful on ivb/ppt when using fdi B/C links - it results in a black screen occasionally, with seemingfully everything working as it should. The only failure indication I've found in the hw is that eventually (but not right after the modeset completes) a pipe underrun is signalled. Big thanks to Arthur Runyan for all the ideas for registers to check and changes to test, otherwise I couldn't ever have tracked this down!
