[Qemu-devel] [PATCH 4/4] qtest/ahci: add port_reset test


From: John Snow
Subject: [Qemu-devel] [PATCH 4/4] qtest/ahci: add port_reset test
Date: Mon, 15 Jun 2015 18:22:45 -0400

Test that we can survive a couple of cycles of running a basic identify
test, some IO, and resetting the HBA. Ensures that we can bring the HBA
back to compliant spec during the lifecycle of the VM.
