rockchip drm.

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

Thanks to the OpenBSD Foundation for sponsoring this work,

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.

drm/drivers: add support for using the arch wc mapping API.

7cf321d118a825c1541b43ca45294126fd474efa in mainline linux

update ttm and radeondrm(4) to Linux 4.4.129

Compared to the previous Linux 3.8 based port this adds support for
KAVERI/KABINI/MULLINS APUs and OLAND/BONAIRE/HAINAN/HAWAII GPUs.

Thanks to the OpenBSD Foundation for sponsoring this work.

define and use trace macros
discussed with kettenis

add back some more static use to reduce the diff to linux

Switch most printf style functions calls back to linux function names
and move DRM_INFO/pr_info/dev_info messages under DRMDEBUG.

switch most mtx_* calls back to linux spinlocks

switch most rwlock calls back to their linux equivalents

Remove DRM_LOCK macros, rename dev_lock to struct_mutex and directly
call linux style lock functions where these macros were used.

reduces the diff to linux and avoids a clang warning brad mentioned

ok jsg@

Add a port of the TTM and Radeon DRM code from Linux 3.8.13.
Includes kernel modesetting, framebuffer console and support
for newer hardware.

Firmware needs to be present for acceleration and in some cases
modesetting to work. It can be installed via fw_update
or manually via pkg_add.

With lots of help from kettenis@ some macppc bits from mpi@
and some ttm refcount/queue bits from FreeBSD.

define and use trace macros
discussed with kettenis

add back some more static use to reduce the diff to linux

Switch most printf style functions calls back to linux function names
and move DRM_INFO/pr_info/dev_info messages under DRMDEBUG.

switch most mtx_* calls back to linux spinlocks

switch most rwlock calls back to their linux equivalents

Remove DRM_LOCK macros, rename dev_lock to struct_mutex and directly
call linux style lock functions where these macros were used.

drm/radeon: also try GART for CPU accessed buffers

add a simplistic version of WARN_ON_ONCE() that doesn't warn
reduces the diff to linux and avoids a clang warning brad mentioned
ok kettenis@ brad@

Call drm_mtrr_add() directly instead adding a map.

ok jsg@

Add a port of the TTM and Radeon DRM code from Linux 3.8.13.
Includes kernel modesetting, framebuffer console and support
for newer hardware.

Firmware needs to be present for acceleration and in some cases
modesetting to work. It can be installed via fw_update
or manually via pkg_add.
