We have now validated that an independent person can build, install and run a SCE capable linux kernel avaliable at: https://github.com/chromi/sce Note that this is evolving code, so expect to see updates, as well as complete notes on new sysctl's avaliable to enable/disable features for testing purposes. > My own > (eventual) contribution to this work might be on the wifi front, but > neither l4s or sce are baked enough yet to bother trying, > IMHO.
