When it comes to Intel hardware enablement on Linux, most of what's been talked about lately is the Haswell
support for the soon-to-be-launched processors. However, the Valley View support on Linux is still being worked on for the next-generation Atom SoC that boasts in-house Intel HD graphics.
I've been talking about Intel's Valley View SoC since being the first to widely expose it last March as a future Atom processor boasting Intel HD graphics
rather than a graphics core derived from Imagination's PowerVR SGX IP. The open-source driver patches for "VLV" have been flowing for nearly one year and continue to be hacked on by the Intel Open-Source Technology Center team.
