Add infrastructure to wait for all planes updates to finish by using an atomic_t variable to track how many pending updates we are waiting plus a wait_queue for the wait part. It also changes vblank behaviour and keeps it enabled for all types of updates Signed-off-by:

The atomic modesetting interfaces supports async commits that should be implemented by the drivers. If drm core requests an async commit exynos_atomic_commit() will now schedule a work task to run the update later. It also serializes commits that needs to run on the same crtc, putting the following commit to wait until the current one is finished. Signed-off-by:

fimd_update_plane() programs BUF_START[win] and during the update BUF_START[win] is copied to BUF_START_S[win] (its shadow register) and starts scanning out, then it raises a irq. The fimd_irq_handler, in the case we have a pending_fb, will check the fb value was copied to START_S register and finish the update in case of success. Based on patch from Daniel Kurtz <djkurtz@chromium.org> Signed-off-by:

This macro is need to get the value of the START shadow register, that will tell if an framebuffer is currently displayed on the screen or not. Signed-off-by:

The current code was ignoring the end of update for all overlay planes, caring only for the primary plane update in case of pageflip. This change adds a change to start to check for pending updates for all planes through exynos_plane->pending_fb. At the start of plane update the pending_fb is set with the fb to be shown on the screen. Then only when to fb is already presented in the screen we set pending_fb to NULL to signal that the update was finished. Signed-off-by:

Only set/clear the update bit in the CRTC's .atomic_begin()/flush() so all planes are really committed at the same time. Signed-off-by:

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk> .prepare_plane() and .cleanup_plane() allows to perform extra operations before and after the update of planes. For FIMD for example this will be used to enable disable the shadow protection bit. Signed-off-by:

Unify handling of finished plane update to prepare for a following patch that will check for the START and START_S regs to really make sure that the plane was updated. Signed-off-by:

struct drm_crtc already stores the enabled state of the crtc thus we don't need to replicate enabled in exynos_drm_crtc. Signed-off-by:

Rather large pull request this time around, due to the long-pending cleanup of the kernel driver being here. There's a stupidly large number of commits for that, as I wanted to have the series be bisectable at a fairly fine-grained level. That said, a very large portion of the churn in the rework was automated, and a very large number of boards from right across the whole range we support have been tested. I'm fairly confident there shouldn't be (too many) issues from this. Beyond correcting some not-so-great design decisions and making the code a lot easier to work with, there's not much exciting (lower memory usage, GPU VM should be a lot faster, etc) to be gained by the end-user as a result of the cleanup, it mostly lays the groundwork for future improvements. A big thanks goes to Alexandre Courbot for testing/debugging the GK20A codepaths for me :) Highlights: - A heap of perfmon work, providing a more useful userspace interface and specifying counters for a bunch of boards - Support for GT200 reclocking + other misc pm improvements - Initial patches towards supporting GM20B (Tegra X1) - Maxwell DisplayPort fixes - Cleanup of the kernel driver - The usual collection of random fixes * 'linux-4.3' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (312 commits) drm/nouveau: bump driver version for release drm/nouveau/tegra: merge platform setup from nouveau drm drm/nouveau/pci: merge agp handling from nouveau drm drm/nouveau/device: remove pci/platform_device from common struct drm/nouveau/device: import pciid list and integrate quirks with it drm/nouveau/device: cleaner abstraction for device resource functions drm/nouveau/mc: move device irq handling to platform-specific code drm/nouveau/mc/gf100-: handle second interrupt tree drm/nouveau/mc: abstract interface to master intr registers drm/nouveau/pci: new subdev drm/nouveau/object: merge with handle drm/nouveau/core: remove the remainder of the previous style drm/nouveau/mpeg: convert to new-style nvkm_engine drm/nouveau/sw: convert to new-style nvkm_engine drm/nouveau/pm: convert to new-style nvkm_engine drm/nouveau/gr: convert to new-style nvkm_engine drm/nouveau/fifo: convert to new-style nvkm_engine drm/nouveau/disp: convert to new-style nvkm_engine drm/nouveau/dma: convert to new-style nvkm_engine drm/nouveau/cipher: convert to new-style nvkm_engine ...
