Yesterday I outlined the AMD Radeon DRM graphics changes
that were queued up for the Linux 3.13 kernel
that will soon be officially under development. Now for Intel Linux customers there's an overview of the Intel DRM graphics driver changes for this next kernel release cycle.
Daniel Vetter of Intel's Open-Source Technology Center has conveniently shared some of the Intel Linux 3.13 DRM graphics changes Saturday on his blog. Among the changes are:
- Much improved Bay Trail / Valley View graphics support... Better support for the brand new Atom SoCs, should you be able to get Linux running on the hardware
. This also includes initial support for being able to initialize the chip without the video BIOS support.
- SWSCI support for new low-power management support. On the power side is also re-worked power-domain handling.
- GPU Boost / Deboost improvements. This will help with the graphics performance for some workloads and will be more aggressive at deboosting the GPU when not experiencing any load, which could lead to a power savings.
- HDMI Stereo/3D support
is now found in the open-source Intel Linux graphics driver.
- Continued work on VMA prep support for PPGTT and watermark handling.
- Display CRC support for hardware checksums exposed via debugfs for allowing for testing some Intel mode-setting code in an automated manner.
- Various bug-fixes and other improvements.
More details on these improvements can be found via Daniel's blog
