* Atomic modesetting conversion progress

* Improved validation of video modes. Some low-power chips can't
drive all DP screens and this is now detected by the driver.

* PSR and FBC improvements and bug fixes

* Workarounds for some specific HDMI monitors needing more time than
allowed by the spec to handle hot-plug events

* As usual, various fixes for little issues here and there

drm/i915: Update to Linux 4.3

* Generic stability improvements

* Stability fixes and support improvements for various GPU families, including
Broxton, Valleyview, Cherryview, Broadwell and Skylake

* Skylake support is no longer considered experimental

* HDMI now uses 12 bits per color component if the screen supports it.

* Power saving features improvements: many fixes have been made to the
PSR (panel self refresh) and FBC (framebuffer compression) code.
These features are not yet enabled by default though.

drm/i915: Update to Linux 4.2

* Work in progress atomic modesetting support

* Broadwell support improvements

* Skylake support improvements, including runtime power management.
Starting from Linux 4.2, a separate firmware blob is required to save
and restore the state of display engines in some low-power modes. These
low-power modes have been forcibly disabled in the DragonFly version of
this driver in order to keep it blob-free.

* Basic Broxton (BXT) support

* Various Displayport improvements including optimized link training,
increased robustness, and automated support for compliance testing

* Execlist overhead reduced

* Frequency boost tuning

* Plenty of bugfixes all around

drm/i915: Update to Linux 4.1

* Valleyview support has been vastly improved and is no longer considered
preliminary

* Skylake support improvements: runtime power management, turbo and sleep
states should now be fully operational.
Many workarounds have been added for Skylake specific issues

* Preliminary changes to prepare for Broxton (future Atom SOCs) support

* Distinguish hardware minimum and user minimum frequencies. Set the GPU
frequency to the hardware minimum on idle in order to reduce power usage

* DRRS (dynamic refresh rate switching) is now enabled where supported.
The idea is to reduce the refresh rate of the panel to save power when
nothing changes on the screen

* DP deadlock bugfixes and improved link rate computation. Intermediate
link rate support for eDP 1.4

* XenGT client-side support. This is paravirtualization to allow virtual
machines to tap into the render engines

* Plenty of internal work to prepare for atomic mode setting

* Lots of other smaller work all over such as added documentation, dead
UMS code removal, vblank interrupt cleanings, etc...

* Panel Self-Refresh (PSR) now supported on Valleyview and Cherryview

* Preparations for atomic display updates

* Performance improvements on various GPU families, including Cherryview,
Broadwell and Haswell

* GPU frequencies are now kept at a minimum of 450MHz when possible
on Haswell and Broadwell, ensuring a minimum experience level for
various types of workloads

* Improved reset support for gen3/4 GPUs, which should fix some OpenGL
crashes on Core 2 and pre-2012 Atom machines

* Better sound/graphics driver synchronization for audio over hdmi support

* As usual, small bugfixes and stability improvements here and there

drm/radeon: Update to Linux 3.17 (v2)

drm/radeon: Update to Linux 3.17 (v2)

Catch up with recent updates in i915kms driver.
While there perform some cleaning in drm and drm/ttm too.

This smallish(1.2MB) diff between Linux v3.12..v3.17 brings
few improvements for radeon cards support on DragonFly BSD.

Driver is VERY experimental even if FF 720p "Hey Mamma"
looks much more pleasing to the eyes on my Xeon box.

Me being Fortran developer(who wants to run OpenCL on BSDs too)
was literally throwing diffs at the fan to see what sticks on.
After cleaning up the mess a bit, these features seems to behave:
kms-syscons switching on R7 240 and 5770 JUNIPER;
current DPorts Xorg;
Xorg-next(1.17.2) + Mesa-next(glamor for radeonsi);
2D tiling now works out of the box on OLAND;
glxgears/cubemap/cuberender mesa demos;
firefox youtube videos(still some blinking on overlays);
mpv -vo vdpau --hwdec=vdpau bsd-0088.mp4 (--vo=opengl too);
UVD (decoding limited to 1080p frame streams);
fragging in OpenArena maxed-out(even ttys[0-8] to quickly check mail);
hdmi audio;
DPM (enabled by default);
gpu temperature monitoring through hw.sensors framework;
automatic firmware loading.

TODO:
update drm/ttm, any help would be really appreciated;
ww_mutex, yep still good old "homegrown" locks;
vma, newer shrinker api;
dma_buf/prime;
iic/i2c rework;
kldunload radeonkms;
better gart sizes support;
newer firmware format support;
fix failing ring sync test to ring-5(UVD);
check how driver supports X2 and IGP cards;
better OpenCL through Clover;
many more.

Thanks goes to:
ftigeot@efnet for opportunity and i915 work
YRabbit@efnet for extensive testing of hdmi A/V on TURKS
ivadasz@efnet for temperature sensors support
mneumann@efnet for testing on HAWAII

AMD for investing time and effort in opensource drivers
NetBSD and Linux gpu developers

Special thanks to:
everyone behind freebsd-ports-graphics/opencl (keep pushing the mngt!)

and that Sweet special girl out there.

drm/i915: Update to Linux 3.16

* Much improved support for Broadwell GPUs. Acceleration should now be fully
operational and the giant L4 eDRAM cache is now enabled when present.

* Baytrail/Valleyview support improvements

* prelimary support for Cherryview (14nm Atom SOCs)

* Various fixes and performance improvements on most other GPU generations

* Improved runtime power management

* 5.4GHz DisplayPort support

* Large cursor support (up to 256x256 pixels), useful for high-dpi displays.

* Mapping of user pages into video memory (userptr)
This allows zero-copy downloads and efficient readback to/from the GPU,
allowing faster rendering of client-side software rasterisers, mitigation
of stalls due to read back and faster pipelining of texture data (such as
pixel buffer objects in GL or data blobs in CL). Mixed CPU/GPU operations
become more efficient in general.
