# 1.12 08-Jun-2020 jsg

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.

# 1.11 14-Apr-2019 jsg

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.

# 1.10 25-Apr-2018 jsg

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.

Add some more i2c glue to reduce the diffs to Linux.


# 1.6 01-Jul-2017 kettenis

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.

# 1.1 12-Aug-2013 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.

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