Expose FBC debugfs files for each crtc. These may or may not point to the same FBC instance depending on the platform. We leave the old global debugfs files in place until igt catches up to the new per-crtc approach. v2: Take a trip via intel_crtc_debugfs_add() (Jani) Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211213151435.9700-1-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>
