To: marius.c.vlad, daniel.vetter, tomeu.vizoso; +Cc: intel-gfx
From: Robert Foss <robert.foss@collabora.com>
Changes since v2:
- Rebased onto trunk which already contains kms_flip_event_leak changes.
Changes since v1:
- kms_vblank: Removed un-used members of data_t struct.
- Rename plane_counter to n_planes.
- Removed un-needed handling CURSOR plane location.
- Added names for additional planes in update kmstest_plane_name.
Robert Foss (4):
lib/igt_kms: Add support for up to 10 planes.
lib/igt_kms: Fix plane counting in igt_display_init.
lib/igt_kms: Switch to verbose assert.
kms_vblank: Switch from using crtc0 statically to explicitly setting
mode.

Finding the first valid connector is pretty much the same work as iterating through all of the connected connectors.
