Intel has now officially enabled support for their next-generation Bay Trail (a.k.a. Valley View) platform within their open-source i965 Mesa graphics driver.
For months there's been open-source work on Valley View
throughout their Linux graphics driver stack, which led us to be the first outfit reporting on an Atom SoC with Ivy Bridge class graphics
. This is the company's first low-power Atom SoC with in-house HD graphics rather than relying upon PowerVR technology from Imagination.
Building upon earlier work, although Valley View is very close from a driver perspective to Ivy Bridge, the commit
to "enable the Bay Trail platform" was made today. This patch adds in the PCI IDs for this foprthcoming hardware.
There are four Bay Trail / Valley View PCI IDs for mobile: 0x0F31, 0x0F32, 0x0F33, and 0x0157. There's also one PCI ID for a "desktop" Bay Trail device: 0x0155.
Bay Trail Atom SoCs are said to be manufactured on a 22nm process, 64-bit capable, a new quad-core architecture, and support LPDDR3 memory, while boasting beautiful in-house Ivy Bridge class graphics.
Bay Trail hardware is expected to appear in the next quarter or two.
