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

Hi, This series includes some pieces of fixes to complete the GK20A power on/off sequences and add the suspend/resume support. The patches 1/11 - 4/11 are based on the linux-next-20141219. The patches 5/11 - 11/11 are based on the branch "linux-3.19" of Ben Skeggs's tree (http://cgit.freedesktop.org/~darktama/nouveau). Thanks, Vince Vince Hsu (4): (linux-next-20141219) ARM:

The FBIOPUT_CON2FBMAP ioctl takes a console_lock(). When this is called while nouveau was runtime suspended, a deadlock would occur due to nouveau_fbcon_set_suspend also trying to obtain console_lock(). Fix this by delaying the drm_fb_helper_set_suspend call. Based on the i915 code (which was done for performance reasons though). Cc: Chris Wilson <chris at chris-wilson.co.uk> Cc: Daniel

Changes since last sent: * add a patch to set the device into DRM_SWITCH_POWER_CHANGING state (can be dropped actually, I thought I was needing it, came up with a different approach and forgot to delete it, doesn't hurt though) * expose information about runtime suspending to nvkm so that we can run the pcie workaround only on runtime suspend Karol Herbst (8): pci: disable ASPM
