...e more power hungry then they need to be, so the nvidia driver writes it's own more optimized set of BLCG settings before enabling CG_CTRL. This adds support for programming the optimized BLCG values during engine/subdev init, which enables rather significant power savings. This introduces the nvkm_therm_clkgate_init() helper, which we use to program the optimized BLCG settings before enabling clockgating with nvkm_therm_clkgate_enable. As well, this commit shares a lot more code with Fermi since BLCG is mostly the same there as far as we can tell. In the future, it's likely we'll reformat the clkgate_...

Next version of my patchseries for adding clockgating support for kepler1 and 2 on nouveau. The first version of this series can be found here: https://patchwork.freedesktop.org/series/36504/ Some very important changes: - Fix gf100_clkgate_init() to actually write registers! This got broken in the last version by accident - Dump the register packs and the resulting register writes into

Next version of my patchseries for adding clockgating support for kepler1 and 2 on nouveau. The first version of this series can be found here: https://patchwork.freedesktop.org/series/36504/ One small change: - Set therm->clkgate_enabled to false until the last patch, where we introduce the NvPmEnableGating option Lyude Paul (5): drm/nouveau: Add support for basic clockgating on

Next version of my patchseries for adding clockgating support for kepler1 and 2 on nouveau. The first version of this series can be found here: https://patchwork.freedesktop.org/series/36504/ Some small changes (shouldn't change anything functionally): - Made gf100_therm_new, gk104_clkgate_pack, and gk110_fb_clkgate_blcg_init_unk_0 static (re: kbuild test bot) - Making all three of

It's here! After a lot of investigation, rewrites, and traces, I present the patch series to implement all known levels of clockgating for Kepler1 and Kepler2 GPUs. Starting with Fermi GPUs (this is probably present on earlier GPUs as well, but with a far less easy to manage interface), nvidia added two clockgating levels that are handled mostly in firmware (with the exception of course, of

Next version of my patchseries for adding clockgating support for kepler1 and 2 on nouveau. The first version of this series can be found here: https://patchwork.freedesktop.org/series/36504/ Some minor changes: - Clarified that SLCG stands for 'secondary level clockgating', thanks for the small tip nvidia! - Removed the concept of levels, this was more useful for debugging then
