nouveau: add runtime PM support (v0.9)
This hooks nouveau up to the runtime PM system to enable dynamic power management for secondary GPUs in switchable and optimus laptops. a) rewrite suspend/resume printks to hide them during dynamic s/r to avoid cluttering logs b) add runtime pm suspend to irq handler, crtc display, ioctl handler, connector status, c) handle hdmi audio dynamic power on/off using magic register. v0.5: make sure we hit D3 properly fix fbdev_set_suspend locking interaction, we only will poweroff if we have no active crtcs/fbcon anyways. add reference for active crtcs. sprinkle mark last busy for autosuspend timeout v0.6: allow more flexible debugging - to avoid log spam add option to enable/disable dynpm got to D3Cold v0.7: add hdmi audio support. v0.8: call autosuspend from idle, so pci config space access doesn't go straight back to sleep, this makes starting X faster. only signal usage if we actually handle the irq, otherwise usb keeps us awake. fix nv50 display active powerdown v0.9: use masking function to enable hdmi audio set busy when we fail to suspend Signed-off-by: Dave Airlie <airlied@redhat.com>
