[kvm-unit-tests,v1,0/3] s390x: mvpg test

Message

Claudio Imbrenda Feb. 9, 2021, 6:51 p.m. UTC

A simple unit test for the MVPG instruction.

The timeout is set to 10 seconds because the test should complete in a
fraction of a second even on busy machines. If the test is run in VSIE
and the host of the host is not handling MVPG properly, the test will
probably hang.

Testing MVPG behaviour in VSIE is the main motivation for this test.

Anything related to storage keys is not tested.

  s390x: check for specific program interrupt
