* Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 tojsg2019-04-141-50/+597
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | 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.

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