Intel Haswell to introduce VECS and VEBOX

Phoronix reports new Haswell Linux patches from Intel reveal a few more details about the video playback enhancements found on these upcoming Intel chips. It looks like these features will be implemented in the forthcoming Linux 3.8 kernel.
Intel has been working on the Haswell open-source Linux enablement for months from compiler optimizations to open-source graphics acceleration code for enabling support for the Ivy Bridge successor as well as future Intel motherboard chipsets for Haswell. Recently they pushed Haswell video acceleration code for exposing VA-API support for hardware-based video acceleration playback on the integrated graphics processor.

The patches reveal that Haswell introduces "VECS", a new command streamer that allows offloading of video post processing to another new component, VEBOX. The VEBOX engine is used for the hardware-based video post processing with supported user-space code. Tuesday's patches touch a few hundred lines of code within the Linux kernel's Intel DRM Driver for supporting VECS/VEBOX.
