^^^ AMD's firmwar updates for the fix are incomplete. Some models won't get firmware updates until November and December. AMD rates the ability to observe data over a process or VM boundary as only "medium" severity. Their customers may have a different opinion... > An updated kernel will set DE_CFG bit 9 on all Zen2 models, > which does not require new microcode. ^^^^ Since AMD is too busy twiddling their fingers with the firmware solutions, we are setting DE_CFG bit 9 _on all the models that we think have the bug_. Two fixes for the same problem, if you get lucky.
