Subject: [PATCH 0/4] hw/arm/virt-acpi-build: Only expose flash on older machine types
Date: Mon, 29 Jun 2020 16:09:34 +0200 [thread overview]
Message-ID: <20200629140938.17566-1-drjones@redhat.com> (raw)
The flash device is exclusively for the host-controlled firmware, so
we should not expose it to the OS. Exposing it risks the OS messing
with it, which could break firmware runtime services and surprise the
OS when all its changes disappear after reboot.
This change was suggested by Ard and Laszlo.
Patch 3/4 is the meat. The other patches deal with updating qtest.
Thanks,
drew
