drm: Use plane->state->fb over plane->fb

2018-03-29T16:14:21+00:00

Stop looking at plane->fb on atomic drivers. Use plane->state->fb
instead.

drm: Make the fb refcount handover less magic

2018-03-29T16:14:21+00:00

Instead of assigning the plane->fb pointer and clearing the fb pointer
to hand over the reference, let's just do it by grabbing another
referece for plane->fb and let fb keep its original one.

drm: Add local 'plane' variable for primary/cursor planes

2018-03-29T16:14:21+00:00

Make the code a bit more readable by storing the plane pointer in a
local variable rather than having to do crtc->{primary,cursor} all the
time.

drm: Check that the plane supports the request format+modifier combo

2018-02-26T14:29:47+00:00

Currently we only check that the plane supports the pixel format of the
fb we're about to feed to it. Extend it to check also the modifier, and
more specifically that the combination of the format and modifier is
supported.

drm/atomic: Handle 64-bit return from drm_crtc_vblank_count()

2018-02-15T19:49:57+00:00

570e86963a51 ("drm: Widen vblank count to 64-bits [v3]") changed the
return type for drm_crtc_vblank_count() to u64.

The flip ioctl receives a 32-bit target sequence from user space and is
compared against the current sequence from drm_crtc_vblank_count(). So,
typecast return from drm_crtc_vblank_count() explicitly to add clarity.

__drm_crtcs_state.last_vblank_count however only ever stores the value from
drm_crtc_vblank_count() and can be upgraded to u64.
