drm/nouveau/mmu: rename from vmmgr (no binary change) Switch to NVIDIA's name for the device. The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau: make sure display hardware is reinitialised on runtime resume Linus commit 05c63c2ff23a80b654d6c088ac3ba21628db0173 modified the runtime suspend/resume paths to skip over display-related tasks to avoid locking issues on resume. Unfortunately, this resulted in the display hardware being left in a partially initialised state, preventing subsequent modesets from completing. This commit unifies the (many) suspend/resume paths, bringing back display (and fbcon) handling in the runtime paths. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/core: convert event handler apis to split create/enable semantics This is a necessary step towards being able to work with the insane locking requirements of the DRM core's vblank routines, and a nice cleanup as a side-effect. This is similar in spirit to the interfaces that Peter Hurley arrived at with his nouveau_event rcu conversion series. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

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>
