Merge branch 'drm-core-next' of git://people.freedesktop.org/~airlied/linux
Pull main drm updates from Dave Airlie: "This is the main merge window request for the drm. It's big, but jam packed will lots of features and of course 0 regressions. (okay maybe there'll be one). Highlights: - new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus (qemu only). These drivers use the generic modesetting drivers. - initial prime/dma-buf support for i915, nouveau, radeon, udl and exynos - switcheroo audio support: so GPUs with HDMI can turn off the sound driver without crashing stuff. - There are some patches drifting outside drivers/gpu into x86 and EFI for better handling of multiple video adapters in Apple Macs, they've got correct acks except one trivial fixup. - Core: edid parser has better DMT and reduced blanking support, crtc properties, plane properties, - Drivers: exynos: add 2D core accel support, prime support, hdmi features intel: more Haswell support, initial Valleyview support, more hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of cleanups and fixes radeon: more HDMI audio support, improved GPU lockup recovery support, remove nested mutexes, less memory copying on PCIE, fix bus master enable race (kexec), improved fence handling gma500: cleanups, 1080p support, acpi fixes nouveau: better nva3 memory reclocking, kepler accel (needs external firmware rip), async buffer moves on nv84+ hw. I've some more dma-buf patches that rely on the dma-buf merge for vmap stuff, and I've a few fixes building up, but I'd decided I'd better get rid of the main pull sooner rather than later, so the audio guys are also unblocked." Fix up trivial conflict due to some duplicated changes in drivers/gpu/drm/i915/intel_ringbuffer.c * 'drm-core-next' of git://people.freedesktop.org/~airlied/linux: (605 commits) drm/nouveau/nvd9: Fix GPIO initialisation sequence. drm/nouveau: Unregister switcheroo client on exit drm/nouveau: Check dsm on switcheroo unregister drm/nouveau: fix a minor annoyance in an output string drm/nouveau: turn a BUG into a WARN drm/nv50: decode PGRAPH DATA_ERROR = 0x24 drm/nouveau/disp: fix dithering not being enabled on some eDP macbooks drm/nvd9/copy: initialise copy engine, seems to work like nvc0 drm/nvc0/ttm: use copy engines for async buffer moves drm/nva3/ttm: use copy engine for async buffer moves drm/nv98/ttm: add in a (disabled) crypto engine buffer copy method drm/nv84/ttm: use crypto engine for async buffer copies drm/nouveau/ttm: untangle code to support accelerated buffer moves drm/nouveau/fbcon: use fence for sync, rather than notifier drm/nv98/crypt: non-stub implementation of the engine hooks drm/nouveau/fifo: turn all fifo modules into engine modules drm/nv50/graph: remove ability to do interrupt-driven context switching drm/nv50: remove manual context unload on context destruction drm/nv50: remove execution engine context saves on suspend drm/nv50/fifo: use hardware channel kickoff functionality ...

[DRM] Invert the sense of the variable that is used to
|
||||||
|
set the brightness of the panel backlight. Normally a
|
||||||
|
brightness value of 0 indicates backlight switched off,
|
||||||
|
and the maximum of the brightness value sets the backlight
|
||||||
|
to maximum brightness. If this parameter is set to 0
|
||||||
|
(default) and the machine requires it, or this parameter
|
||||||
|
is set to 1, a brightness value of 0 sets the backlight
|
||||||
|
to maximum brightness, and the maximum of the brightness
|
||||||
|
value switches the backlight off.

-1 -- never invert brightness

Say yes for experimental AST GPU driver. Do not enable
|
||||||
|
this driver without having a working -modesetting,
|
||||||
|
and a version of AST that knows to fail if KMS
|
||||||
|
is bound to the driver. These GPUs are commonly found
|
||||||
|
in server chipsets.
