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: https://lore.kernel.org/r/20230203051459.1354589-1-aik@amd.com
This is based on sha1 f91f9332d782 Ingo Molnar "Merge branch into tip/master: 'x86/tdx'".
Please comment. Thanks.
Alexey Kardashevskiy (6): KVM: SEV: move set_dr_intercepts/clr_dr_intercepts from the header KVM: SEV: Move SEV's GP_VECTOR intercept setup to SEV KVM: SEV-ES: explicitly disable debug KVM: SVM/SEV/SEV-ES: Rework intercepts KVM: SEV: Enable data breakpoints in SEV-ES x86/sev: Do not handle #VC for DR7 read/write
