We're trying to introduce support for writeback connectors, a way to
expose in DRM the hardware functionality from display engines that
allows to write back into memory the result of the DE's composition
of supported planes.
Although this is a rebase of v3 with all the comments addressed, I'm not
expecting people to remember any of the previous versions, please review
this as if it is a new series.
Patches have been originally implemented by Brian, I've done the v3 and v4
updates to them.
Best regards,
Liviu

all the changes that were trying to split the CRC functionality out
of lib/igt_debugfs.c. v2 is here:
