[igt-dev] [PATCH i-g-t 03/14] tools/intel_vbt_decode: update vbt defs from kernel

Ville Syrjala ville.syrjala at linux.intel.com
Fri Jul 15 20:25:09 UTC 2022


From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Sync up the the VBT definitions from kernel commit
<fixme>
and adjust the actual code to match.

Note that 'slave_port' is gone now, so we'll just throw it out,
and the DP redriver stuff is now defined as bitfields which need
to be properly decoded.
