AMD microcode and AGESA updates available on several platofrms... time table here: https://www.amd.com/en/resources/product-security/bulletin/a...

Expect to see BIOS and OS updates soon if not already out. I believ Microsoft has already pushed a cumulative that includes some mitigations.

> No µcode patch or BIOS update, which includes the µcode patch, is necessary for products based on “Zen” or “Zen 2” CPU architectures because these architectures are already designed to flush branch type predictions from the branch predictor.
