AGESA 1.0.0.6b Might Fix The Ryzen Linux Performance Marginality Problem

While newer Ryzen CPUs are running great on Linux without the performance marginality problem as described by AMD, since yesterday I have begun receiving unconfirmed reports from Phoronix readers that the recent AGESA 1.0.0.6b revision does address the issue via this software update.
But unfortunately details on AGESA 1.0.0.6b are light. Most of the web pages / threads referencing AGESA 1.0.0.6b are actually inquiring about the changes to be found in this update, but few actual details on this update that has been surfacing in the past two weeks via BIOS updates.
After beginning to receive reader statements since yesterday that AGESA 1.0.0.6b addresses the Linux "performance marginality problem", I reached out to some AMD contacts when waking up this morning. Unfortunately, as of ending out the day, I have yet to receive any comment from any of them whether this update is expected to address the problem.
Since then as well I have received a comment from the reader of being able to reproduce the performance marginality problem under Windows. There is now the kill-ryzen-win script that also seeks to illustrate Ryzen issues when using Visual Studio C/C# compilation. But we'll see if the latest AGESA update takes care of that too or if hearing anything else from AMD.
