Subject: [PATCH kernel v3 0/3] KVM: SEV: Enable AMD SEV-ES DebugSwap
Date: Fri, 20 Jan 2023 14:10:44 +1100 [thread overview]
Message-ID: <20230120031047.628097-1-aik@amd.com> (raw)
This is to use another AMD SEV-ES hardware assisted register swap,
more detail in 2/3. The patches are fairly independend but required in
this order.
The previous conversation is here:
https://lore.kernel.org/all/20221209043804.942352-1-aik@amd.com/
This is based on sha1
195df42eb64d Ingo Molnar "Merge branch into tip/master: 'x86/platform'"
in order to have recently added X86_FEATURE_NO_NESTED_DATA_BP cpu
feature.
Please comment. Thanks.
