Subject: [PATCH v2 0/4] clean up interface between KVM and psp
Date: Wed, 18 Aug 2021 05:39:04 +0000	[thread overview]
Message-ID: <20210818053908.1907051-1-mizhang@google.com> (raw)

This patch set starts from a minor fix patch by adding sev decommission;
the rest 3 patches are trying to help make the interface between KVM and
psp cleaner and simpler. In particular, these patches do the following
improvements:
 - avoid the requirement of psp data structures for some psp APIs.
 - hide error handling within psp API, eg., using sev_guest_decommission.
 - hide the serialization requirement between DF_FLUSH and DEACTIVATE.

v1 -> v2:
 - split the bug fixing patch as the 1st one.
 - fix the build error. [paolo]

Mingwei Zhang (3):
  KVM: SVM: move sev_decommission to psp driver
  KVM: SVM: move sev_bind_asid to psp
  KVM: SVM: move sev_unbind_asid and DF_FLUSH logic into psp
