David Airlie of Red Hat sent in the DRM pull request for the 3.16 merge window with a plethora of changes this time around:
- The Nouveau driver has initial support for the GK20A Kepler graphics core found within the Tegra K1 ARM SoC.
- The other big Nouveau change is initial support for re-clocking on certain generations of NVIDIA chipsets. The support is limited to a few series where it should be working, is static, and can be rather buggy.
- Other Nouveau changes include GK110B GPU support for the high-end GeForce 700 series Keplers, a DisplayPort rework, GK208 fixes, and other changes.
- A ton of Intel graphics improvements like support for larger cursor sizes (aimed for HiDPI displays), Cherryview support, Userptr support, and a variety of lower-level improvements.
- Important for the Radeon driver in Linux 3.16 is GPU VM optimizations and HDMI deep color support. There's also GART fixes, HDMI audio clean-ups, and other changes.
- The AST driver experienced a rare update to support the AST2400 hardware.
- IPUV3 moved out of staging and into the GPU DRM area as a Freescale Image Processing Unit V3 DRM driver for i.MX SoCs.
- Various other changes to the included DRM drivers plus some core DRM improvements.
