Subject: [kvm-unit-tests PATCH 0/3] x86: hyper-v: Add overlay page tests

Message-ID: <cover.1623346319.git.sidcha@amazon.de> (raw)

Patch series [1] starts treating hypercall code page as an overlay page
(along with the existing synic event and message pages). Add KVM unit
tests to make sure the underlying page contents are intact with various
overlay workflows.

While at it, promote hyperv.h to lib/x86 and expose hv_hypercall() from
there so future tests can use it to do hypercalls.
