update drm to linux 5.10.47

hardware support changes include
inteldrm: better support for tiger lake
amdgpu: support for navi12, navi21 "sienna_cichlid", arcturus
amdgpu: support for cezanne "green sardine" ryzen 5000 apu

update drm to linux 5.7

adds kernel support for
amdgpu: vega20, raven2, renoir, navi10, navi14
inteldrm: icelake, tigerlake

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping, patrick@ for helping adapt rockchip drm and many developers for
testing.

Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to
linux 4.19.34.

Adds support for more Intel hardware:
Broxton/Apollo Lake (was is_preliminary in 4.4)
Amber Lake (another Kaby Lake refresh)
Gemini Lake
Coffee Lake
Whiskey Lake
Cannon Lake (though no hardware with Intel graphics ever shipped)
Ice Lake (alpha support, hardware not released)

This does not add support for new radeon hardware on the AMD side as
newer radeons have a different kernel driver (amdgpu).

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping and a bunch of other developers for testing.

Update inteldrm(4) to code based on Linux 4.4.70. This brings us support for
Skylake and Cherryview and better support for Broadwell and Valleyview. Also
adds MST support. Some tweaks to the TTM code and radeondrm(4) to keep it
working with the updated generic DRM code needed for inteldrm(4).

Tested by many.

Update inteldrm to the code from Linux 3.14.52 (which corresponds to
commit 48f8f36a6c8018c2b36ea207aaf68ef5326c5075 on the linux-3.14.y
branch of the linux-stable tree). This brings preliminary support for
the GPU on Intel's Broadwell CPUs. Don't expect these to work
perfectly yet. There are some remaining issues with older hardware as
well, but no significant regressions have been uncovered.

This also updates some of drm core code. The radeondrm code remains
based on Linux 3.8 with some minimal canges to adjust to changes in
the core drm APIs.

Joint effort with jsg@, who did the initial update of the relevant drm
core bits. Committing this early to make sure it gets more testing
and make it possible for others to help getting the remaining wrinkles
straightened out.

switch to the drm_mm based gtt eviction code from linux 3.8.13
ok kettenis@

Move most of the uses of workqs in drm to the new task/taskq api.
Prevents unintended multiple additions to workqs that was causing
hangs on radeon, and lets us remove tasks more closely matching
the behaviour of the original linux code.

ok kettenis@
cause of the ttm/radeon hangs debugged by claudio@ and kettenis@

Another major overhaul of the inteldrm(4) GEM code, bringing us considerably
closer to the Linux 3.8.13 codebase. Almost certainly squashes a few more
bugs.

ok jsg@

Another round of reducing diffs with Linux code.

move i915_gem_find_inactive_object() into i915_gem_evict.c

Significantly increase the wordlist for ddb hangman,
and update our device independent DRM code and the Intel DRM code
to be mostly in sync with Linux 3.8.3. Among other things this
brings support for kernel modesetting and enables use of
the rings on gen6+ Intel hardware.

Based on some earlier work from matthieu@ with some hints from FreeBSD
and with lots of help from kettenis@ (including a beautiful accelerated
wscons framebuffer console!)

Based on some earlier work from matthieu@ with some hints from FreeBSD
and with lots of help from kettenis@ (including a beautiful accelerated
wscons framebuffer console!)

Thanks to M:Tier and the OpenBSD Foundation for sponsoring this work.

Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to
linux 4.19.34.

Adds support for more Intel hardware:
Broxton/Apollo Lake (was is_preliminary in 4.4)
Amber Lake (another Kaby Lake refresh)
Gemini Lake
Coffee Lake
Whiskey Lake
Cannon Lake (though no hardware with Intel graphics ever shipped)
Ice Lake (alpha support, hardware not released)

This does not add support for new radeon hardware on the AMD side as
newer radeons have a different kernel driver (amdgpu).

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping and a bunch of other developers for testing.

Update inteldrm(4) to code based on Linux 4.4.70. This brings us support for
Skylake and Cherryview and better support for Broadwell and Valleyview. Also
adds MST support. Some tweaks to the TTM code and radeondrm(4) to keep it
working with the updated generic DRM code needed for inteldrm(4).

Tested by many.

Update inteldrm to the code from Linux 3.14.52 (which corresponds to
commit 48f8f36a6c8018c2b36ea207aaf68ef5326c5075 on the linux-3.14.y
branch of the linux-stable tree). This brings preliminary support for
the GPU on Intel's Broadwell CPUs. Don't expect these to work
perfectly yet. There are some remaining issues with older hardware as
well, but no significant regressions have been uncovered.

This also updates some of drm core code. The radeondrm code remains
based on Linux 3.8 with some minimal canges to adjust to changes in
the core drm APIs.

Joint effort with jsg@, who did the initial update of the relevant drm
core bits. Committing this early to make sure it gets more testing
and make it possible for others to help getting the remaining wrinkles
straightened out.

switch to the drm_mm based gtt eviction code from linux 3.8.13
ok kettenis@

Move most of the uses of workqs in drm to the new task/taskq api.
Prevents unintended multiple additions to workqs that was causing
hangs on radeon, and lets us remove tasks more closely matching
the behaviour of the original linux code.

Another major overhaul of the inteldrm(4) GEM code, bringing us considerably
closer to the Linux 3.8.13 codebase. Almost certainly squashes a few more
bugs.

ok jsg@

Another round of reducing diffs with Linux code.

move i915_gem_find_inactive_object() into i915_gem_evict.c

Significantly increase the wordlist for ddb hangman,
and update our device independent DRM code and the Intel DRM code
to be mostly in sync with Linux 3.8.3. Among other things this
brings support for kernel modesetting and enables use of
the rings on gen6+ Intel hardware.
