[kvm-unit-tests RFC 0/2] s390x: Add snippet support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The SIE support allows us to run guests and test the hypervisor's
(V)SIE implementation. However it requires that the guest instructions
are binary which limits the complexity of the guest code.

The snippet support provides a way to write guest code as ASM or C and
simply memcpy it into guest memory. Some of the KVM-unit-test library
can be re-used which further speeds up guest code development.

The included mvpg-sie test helped us to deliver the KVM mvpg fixes
which Claudio posted a short while ago. In the future I'll post Secure
Execution snippet support patches which was my initial goal with this
series anyway.

I heard you liked tests so I put tests inside tests so you can test
while you test.
