Revert r338177, r338176, r338175, r338174, r338172
After long consultations with re@, core members and mmacy, revert
these changes. Followup changes will be made to mark them as
deprecated and prent a message about where to find the up-to-date
driver. Followup commits will be made to make this clear in the
installer. Followup commits to reduce POLA in ways we're still
exploring.
It's anticipated that after the freeze, this will be removed in
13-current (with the residual of the drm2 code copied to
sys/arm/dev/drm2 for the TEGRA port's use w/o the intel or
radeon drivers).
Due to the impending freeze, there was no formal core vote for
this. I've been talking to different core members all day, as well as
Matt Macey and Glen Barber. Nobody is completely happy, all are
grudgingly going along with this. Work is in progress to mitigate
the negative effects as much as possible.

Remove legacy drm and drm2 from tree2018-08-22T01:50:12ZMatt Macymmacy@FreeBSD.org2018-08-22T01:50:12Zurn:sha1:d157fbd5b4b59aa863cbb82d4ad08596996d3ab0
As discussed on the MLs drm2 conflicts with the ports' version and there
is no upstream for most if not all of drm. Both have been merged in to
a single port.
Users on powerpc, 32-bit hardware, or with GPUs predating Radeon
and i915 will need to install the graphics/drm-legacy-kmod. All
other users should be able to use one of the LinuxKPI-based ports:
graphics/drm-stable-kmod, graphics/drm-next-kmod, graphics/drm-devel-kmod.

Allow DRM2 code to be built on platforms without AGP.2016-11-13T13:31:23ZMichal Melounmmel@FreeBSD.org2016-11-13T13:31:23Zurn:sha1:aa1f683bf3a2008d4e8048249bef93e646f5ad3c
This patch is taken from original drm-3.8 code.

drm: Update the device-independent code to match Linux 3.8.132015-03-17T18:50:33ZJean-Sébastien Pédrondumbbell@FreeBSD.org2015-03-17T18:50:33Zurn:sha1:455fa6518ac6e2c25197085a8b900451487642b4
This update brings few features:
o Support for the setmaster/dropmaster ioctls. For instance, they
are used to run multiple X servers simultaneously.
o Support for minor devices. The only user-visible change is a new
entry in /dev/dri but it is useless at the moment. This is a
first step to support render nodes [1].
The main benefit is to greatly reduce the diff with Linux (at the
expense of an unreadable commit diff). Hopefully, next upgrades will be
easier.
No updates were made to the drivers, beside adapting them to API
changes.

An update for the i915 GPU driver, which brings the code up to Linux2015-01-21T16:10:37ZKonstantin Belousovkib@FreeBSD.org2015-01-21T16:10:37Zurn:sha1:47671d1babdc480b91b25e8293f8a7b5d3021096
commit 4d93914ae3db4a897ead4b. Some related drm infrastructure
changes are imported as needed.
Biggest update is the rewrite of the i915 gem io to more closely
follow Linux model, althought the mechanism used by FreeBSD port is
different.

Add the code for new Intel GPU driver, which supports GEM, KMS and2012-05-22T11:07:44ZKonstantin Belousovkib@FreeBSD.org2012-05-22T11:07:44Zurn:sha1:e27f8719698efb2ddc197caac633aa3b97e2ac1b
works with new generations of GPUs (IronLake, SandyBridge and
supposedly IvyBridge).
The driver is not connected to the build yet.
