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

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

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/ 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

Commit d32656373857 ("drm/nouveau/therm/gp100: initial implementation of new gp1xx temperature sensor") added support for reading finer-grain temperatures, but continued to report temperatures in 1 degree Celsius increments via nvkm_therm_temp_get(). Rather than altering nvkm_therm_temp_get() to report finer-grain temperatures, which would be inconvenient for other users of the
