This post seems to indicate that there is no kernel-level workaround for variant 1, that contradicts AMD’s statement: https://www.amd.com/en/corporate/speculative-execution

LWN seems right on this one, that makes me question AMD’s honesty and knowledge of the issue.

At this point, both Intel and AMD press releases should be treated as highly, highly suspect. They are both jockeying to mitigate money loss or take advantage to make money. The truth is a secondary concern.

I'd believe CERT, project zero and the independent linux kernal devs if you want the truth.

I'm not 100% sure here, but I believe this is the specific kernel level fix that also addresses variant 1 https://lkml.org/lkml/2017/12/27/2

No KPTI does not address variant 1.
