Komeda driver treats KMS-CRTC/PLANE as user which will acquire pipeline resources, but we still need to release the unclaimed resources. crtc_atomic_check is the final check stage, so beside build a display data pipeline according the crtc_state, but still needs to release/disable the unclaimed pipeline resources. v2: Rebase Signed-off-by:

Per komeda design KMS-plane maps to komeda layer input pipeline. komeda_plane_atomic_check is for building a komeda layer input pipeline. And KMS-plane is only a user of komeda resources. so there is no real HW update for plane, but all HW update will be handled in crtc->flush. v2: Rebase Signed-off-by:

With the previous patch drm_crtc_find will return NULL when the crtc isn't in our lease, which will then disable the plane/connector. No longer an issue since the lessor can't escape their lease terms anymore, but not quite great semantics yet either. Catch this and return -EACCES, so that at least evil test cases have a better chance of making sure the kernel works correctly. Reviewed-by:

We need this to make sure lessees can only connect their plane/connectors to crtc objects they own. And note that this is irrespective of whether the lessor is atomic or not, lessor cannot prevent lessees from enabling atomic.

If userspace doesn't enable universal planes, then we automatically add the primary and cursor planes. But for universal userspace there's no such check (and maybe we only want to give the lessee one plane, maybe not even the primary one), hence we need to check for the implied plane. v2: don't forget setcrtc ioctl. v3: Still allow disabling of the crtc in SETCRTC.
