This patchset adds a debugfs file that prints info about the
framebuffers.
I have followed the style of drm_state_info(). This means that the added
drm_framebuffer_print_info() could also be used in
drm_atomic_plane_print_state(). In order to do that I had to add a way
to vary indentation to fit both use cases.
Changes in this version is turning drm_printf_indent() into a macro and
converting the rest of the cma helper drivers.
This is how it looks:
$ sudo cat /sys/kernel/debug/dri/0/framebuffer
framebuffer[33]:
refcount=3
format=RG16 little-endian (0x36314752)
modifier=0x0
size=320x240
layers:
size[0]=320x240
pitch[0]=640
offset[0]=0
obj[0]:
name=0
refcount=1
start=00010000
size=155648
imported=no
paddr=0x17c80000
vaddr=d7c80000
$ sudo cat /sys/kernel/debug/dri/0/state
plane[28]: plane-0
