Daniel Vetter as the Intel DRM maintainer published a set of drm-intel-testing updates on Friday for their kernel graphics driver. One of the big highlights of this latest code that's up for public testing is RPS/Turbo support for the yet-to-be-released Cherryview hardware, which is the next-gen Atom SoCs. Cherryview support landed with the Linux 3.15 but is being further refined still as the hardware is still months from surfacing. Cherryview features Airmont CPU cores that are the 14nm shrink of Silvermont and feature Intel Broadwell "Gen8" based graphics. The release of Intel Cherryview hardware is expected in September. Besides the RPS/Turbo support are also other Cherryview "CHV" Linux patches.
Other early Intel Linux graphics code for the 3.17 cycle includes universal plane conversion for the primary plane, PPGTT for Bay Trail / Valley View hardware, and many other code clean-ups and minor improvements throughout this first-rate Linux graphics driver.
More information on this initial 3.17 drm-intel-testing set of changes can be found via the intel-gfx list. The Intel testing code is available from this Git branch.
