Hello,
As per:
File fb_sys_fops
This file provides convenient implementations for read/write syscalls on the
/dev/fb{N} operation, which simply copies bytes between userspace buffers and
the memory-mapped video buffer set up by the framebuffer driver. It presumably
assumes that the user data is in the appropriate format already.
As noted above, there is a default implementation of read/write/etc in file
fbmem.c. These alternate implementations can be used by a driver simply by
setting the appropriate member in its ops structure (which the fbmem code
checks before calling its default).
It says it supports read/write so where is the install being called at/from?
systemd-udevd Error running install command for fb_sys_fops
Thanks,
Brad
