It is helpful for debugging to know in which state the available planes on an
output are when a layout is applied that leads to a change.
For that log all planes that are compatible with the output. Currently disabled
planes have multiple properties logged per line to keep the log short.
Example:
== Apply request for output 62 ==
Note: Reused previous plane allocation 5 times.
Available planes (on output 62):
Plane 55:
type: primary
FB_ID: 93
IN_FENCE_FD: -1
CRTC_ID: 62
CRTC_X: 39
CRTC_Y: 0
CRTC_W: 3761
CRTC_H: 2160
SRC_X: 0
SRC_Y: 0
SRC_W: 2349
SRC_H: 1349
COLOR_ENCODING: 0
COLOR_RANGE: 0
Plane 61 (inactive):
type: cursor FB_ID: 0 IN_FENCE_FD: -1 CRTC_ID: 0
CRTC_X: 0 CRTC_Y: 0 CRTC_W: 0 CRTC_H: 0
SRC_X: 0 SRC_Y: 0 SRC_W: 0 SRC_H: 0
Plane 58 (inactive):
type: overlay FB_ID: 0 IN_FENCE_FD: -1 CRTC_ID: 0
CRTC_X: 0 CRTC_Y: 0 CRTC_W: 0 CRTC_H: 0
SRC_X: 0 SRC_Y: 0 SRC_W: 0 SRC_H: 0
