Discussion

Version updates

  • 38, 36, and 35 branches are all merged now.
  • 38.4 has new master prefixed branch rather than merging into the master-l4t
  • New focus for Thor on this branch

36.5 update and change in OOT modules builds

  • Nvidia sources are now all mirrored into an account on gitlab which makes fetching more reliable than their previous gerrit server
  • Modified to all reference Nvidia gitlab sources instead of sources from OE4T
  • OE4T patches are now kept in the layer, 36.4 has 200 patches.
  • Can either use download source tarball or git repos, recipes use the source tarball by default but if you need to make modifications you can use the git recipes instead.
    • If you don’t care about development the tarball is faster.
    • May be necessary to fork the git repos in the future, if that happens will switch to use git repos by default.
    • May want to in the future limit whether we can only use tarballs for specific scenarios, like when using the default nvidia kernel. Freescale does something similar with their vendor kernel versus the community kernel.
  • Should be possible to use devtool with git repos.
  • Original 36.4 update had issues with the feature check script from nvidia, found/fixed those problems.
  • Used nvidia patches when available so when they do updates we can easily just remove the backports.
  • Should have a wider range of kernel checks which drivers should work with using the feature check script.
  • Everything is the same all the way back to scarthgap, same patches are applied, also the same whether using tarball or git repos.
