DPM (динамическое управление питанием) в открытых драйверах AMD
Будет в ядре 3.11, для карт от R600 до SI. Также присутствует поддержка PCIe ASPM.
Ну и бонус: поддержка Sea Islands (Radeon HD 8000).
From: Alex Deucher <alexander.deucher@amd.com>
These are the radeon patches for 3.11. Some of these patches
are huge so, it might be easier to review things here:
http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.11-wipI'll send a formal pull in request in the next day or two.
Highlights of this series:
- DPM support (Dynamic Power Management) for r6xx-SI
- Support for CIK (Sea Islands): modesetting, 3D, compute, UVD
- ASPM support for R6xx-SISince this is the initial public DPM code, it's still disabled by default until we get more community testing. Pass dpm=1 to the radeon module to enable it.
