EDID Override - Injecting a Dolby VSVDB Block

Latest Update

  • Rebase on latest CE 21.1
  • Change names of Dolby Vision Type to be hopefully more descriptive:
    • Display Led (DV-STD)
    • Player Led (DV-LL)
    • Player Led (HDR)
  • Some tweaking on stability

For the stability I also have a ssh command to run, not integrated into the build yet.
I have so far not been able to make it crash-reboot, switching between lots of different content types stopping and starting quickly, though Murphy’s law will say someone will still get a crash almost on the first attempt! but looking good to me.

echo 31 > /sys/module/amdolby_vision/parameters/force_update_reg

Can add to your autosys.sh for now, for just run once and see if have issues in that session.

This looks a bit brute force but not seen any side effects and if anything anecdotally feels a little smoother. But do be on the look out for anything odd happening picture issues etc.
