drm/mgag200: Index 24 in extended CRTC registers is 24 in hex, not decimal.

2013-04-12T16:52:09+00:00

commit 1812a3db0874be1d1524086da9e84397b800f546 upstream. This change properly enables the "requester" in G200ER cards that is responsible for getting pixels out of memory and clocking them out to the screen.

drm: correctly restore mappings if drm_open fails

2013-04-12T16:52:04+00:00

commit a8ec3a662921220fc058ed6f7f3674697876d218 upstream. If first drm_open fails, the error-handling path will incorrectly restore inode's mapping to NULL. This can cause the crash later on. Fix by separately storing away mapping pointers that drm_open can touch and restore each from its own respective variable if the call fails. Fixes: https://bugzilla.novell.com/show_bug.cgi?id=807850 (thanks to Michal Hocko for investigating investigating and finding the root cause of the bug) Reference: http://lists.freedesktop.org/archives/dri-devel/2013-March/036564.html v2: Use one variable to store file and inode mapping since they are the same at the function entry. Fix spelling mistakes in commit message. v3: Add reference to the original bug report.

drm/i915: Be sure to turn hsync/vsync back on at crt enable (v2)

2013-04-12T16:52:04+00:00

commit 637f44d24f8868ee5a597a99e7874fdd150d4cba upstream. commit f40ebd6bcbbd0d30591f42dc16be52b5086a366b Author: Patrik Jakobsson Date: Tue Mar 5 14:24:48 2013 +0100 drm/i915: Turn off hsync and vsync on ADPA when disabling crt properly disabled the hsync/vsync logic at disable time, but neglected to re-enable them at enable time. v2: In the enable hook, restore the connector's expected DPMS level instead of forcing ON. Do this by stashing a back pointer to the connector in the crt (suggested by danvet) since otherwise it's awkward to look up.

drm/nouveau: fix handling empty channel list in ioctl's

2013-04-12T16:52:04+00:00

commit b43decd2c513ae44a5462a1a4c2622f0fa77c9e0 upstream. If there are no channels, chan would never end up being NULL, and so the null pointer check would fail. Solve this by initializing chan to NULL, and iterating over temp instead. Fixes oops when running intel-gpu-tools/tests/kms_flip, which attempts to do some intel ioctl's on a nouveau device.

drm/i915: Don't clobber crtc->fb when queue_flip fails

2013-04-05T16:26:15+00:00

commit 4a35f83b2b7c6aae3fc0d1c4554fdc99dc33ad07 upstream. Restore crtc->fb to the old framebuffer if queue_flip fails. While at it, kill the pointless intel_fb temp variable. v2: Update crtc->fb before queue_flip and restore it back after a failure. Backported for 3.8-stable. Restored an atomic_sub removed in 3.9 ca9c46.

drm/i915: Use the fixed pixel clock for eDP in intel_dp_set_m_n()

2013-04-05T16:26:15+00:00

commit 9d1a455b0ca1c2c956b4d9ab212864a8695270f1 upstream. The eDP output on HP Z1 is still broken when X is started even after fixing the infinite link-train loop. The regression was introduced in 3.6 kernel for cleaning up the mode clock handling code in intel_dp.c by the commit [71244653: drm/i915: adjusted_mode->clock in the dp mode_fix]. In the past, the clock of the reference mode was modified in intel_dp_mode_fixup() in the case of eDP fixed clock, and this clock was used for calculating in intel_dp_set_m_n(). This override was removed, thus the wrong mode clock is used for the calculation, resulting in a psychedelic smoking output in the end. This patch corrects the clock to be used in the place. v1->v2: Use intel_edp_target_clock() for checking eDP fixed clock instead of open code as in ironlake_set_m_n(). Backported for 3.8-stable. Reverted refactoring in e69d0bc1. Signed-off-by: Takashi Iwai Signed-off-by: Daniel Vetter Signed-off-by: Lingzhu Xiang Reviewed-by: CAI Qian Signed-off-by: Greg Kroah-Hartman
