Intel DRM Driver Gets Support For Multiple Power Wells
As hopefully a sign that Intel will soon be publishing their open-source graphics driver code for next year's Broadwell platform, new patches emerged today for supporting multiple power wells to be present on "upcoming hardware" out of Intel.
Intel has been working towards Broadwell Linux support but there hasn't been any big code drops yet of Broadwell enablement within the Intel DRM / Mesa / xf86-video-intel. However, today by Intel's Imre Deak were a new set of eight patches implementing support for multiple power wells -- with Haswell there is just one dynamic well. "This patchset adds support for multiple dynamic power wells needed by
HW generations so far had only one always-on power well and optionally one dynamic power well. Upcoming HW gens may have multiple dynamic power wells, so add some infrastructure to support them.
The patch series can be found on intel-gfx.
