Just use the acpi interface. That's what windows uses on this generation and it's the only thing that seems to work reliably on these generation parts. You can still force the native backlight interface by setting radeon.backlight=1 Bug: https://bugzilla.kernel.org/show_bug.cgi?id=88501 v2: merge into above if/else block Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
It's magic, but it seems to work.

drm/i915: Only unbind vgacon, not other console drivers
My best guess is that the vga fbdev driver falls over if we rip out
parts of vgacon. Hooray.

drm/tegra: Fixes for v3.18-rc5 This is a single patch that fixes the VBLANK machinery after: 7ffd7a68511c drm: Always reject drm_vblank_get() after drm_vblank_off() * tag 'drm/tegra/for-3.18-rc5' of git://people.freedesktop.org/~tagr/linux: drm/tegra: dc: Add missing call to drm_vblank_on()
One modesetting, one gk20a fix. * 'linux-3.18' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: drm/nouveau/nv50/disp: Fix modeset on G94 drm/gk20a/fb: fix setting of large page size bit
one regression fix. * tag 'drm-intel-fixes-2014-11-13' of git://anongit.freedesktop.org/drm-intel: drm/i915: Fix obj->map_and_fenceable across tiling changes
When the CRTC is enabled, make sure the VBLANK machinery is enabled. Failure to do so will cause drm_vblank_get() to not enable the VBLANK on the CRTC and VBLANK-synchronized page-flips won't work. While at it, get rid of the legacy drm_vblank_pre_modeset() and drm_vblank_post_modeset() calls that are replaced by drm_vblank_on() and drm_vblank_off().

Commit 1dce6264045cd23e9c07574ed0bb31c7dce9354f introduced a regression spotted on several G94 (FDObz #85160).
