[PATCH kernel v5 0/6] KVM: SEV: Enable AMD SEV-ES DebugSwap

From: Alexey Kardashevskiy
Date: Tue Apr 11 2023 - 08:57:49 EST


This is to use another AMD SEV-ES hardware assisted register swap,
more detail in 5/6. In the process it's been suggested to fix other
things, here is the attempt, with the great help of amders.

The previous conversation is here:

This is based on sha1
f91f9332d782 Ingo Molnar "Merge branch into tip/master: 'x86/tdx'".

Please comment. Thanks.
