From: Martin Peres <martin.peres at labri.fr> This should fix a deadlock that has been reported to us where fan_update() would hold the fan lock and try to grab the alarm_program_lock to reschedule an update. On an other CPU, the alarm_program_lock would have been taken before calling fan_update(), leading to a deadlock. We should Cc: <stable at vger.kernel.org> # 3.9+ Reported-by:

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

Hi all, This series aims to fix almost all remaining fall-through warnings in order to enable -Wimplicit-fallthrough for Clang. In preparation to enable -Wimplicit-fallthrough for Clang, explicitly add multiple break/goto/return/fallthrough statements instead of just letting the code fall through to the next case. Notice that in order to enable -Wimplicit-fallthrough for Clang, this change[1]

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 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

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
