Various notebooks with nvidia GPUs generate an ACPI_VIDEO_NOTIFY_PROBE acpi-video event when an external device gets plugged in (and again on modesets on that connector), the default behavior in the acpi-video driver for this is to send a KEY_SWITCHVIDEOMODE evdev event, which causes e.g. gnome-settings-daemon to ask us to rescan the connectors (good), but also causes g-s-d to switch to mirror

...d. >From a quick look, it looks like a suitable mechanism except for the removal on runtime suspend. Based on commit logs for core/core/event.c, the event system seems initially used for communication between drm and nouveau, later this was extended to userspace notifications.

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

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

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
