Subject: [PATCH v8 3/6] automation: prevent QEMU access to /dev/mem in PCI passthrough tests
Date: Fri, 10 May 2024 05:53:23 +0200 [thread overview]
Message-ID: <38e018c5e94020ba37b5571088033cc6b648a8c9.1715313192.git-series.marmarek@invisiblethingslab.com> (raw)
In-Reply-To: <cover.33fb4385b7dd6c53bda4acf0a9e91748b3d7b1f7.1715313192.git-series.marmarek@invisiblethingslab.com>
/dev/mem access doesn't work in dom0 in lockdown and in stubdomain.
Simulate this environment with removing /dev/mem device node. Full test
for lockdown and stubdomain will come later, when all requirements will
be in place.

This can be applied only after QEMU change is committed. Otherwise the
test will fail.
