[PATCH 5/5] hw/i386: expose a "smbios_ep" PC machine property |
Date: |
Tue, 8 Sep 2020 17:54:38 +0100 |
The i440fx and Q35 machine types are both hardcoded to use the legacy
SMBIOS 2.1 entry point. This is a sensible conservative choice because
SeaBIOS only supports SMBIOS 2.1
EDK2, however, can also support SMBIOS 3.0 and QEMU already uses this on
the ARM virt machine type.
This adds a property to allow the choice of SMBIOS entry point versions
For example to opt in to version 3.0
$QEMU -machine q35,smbios_ep=3_0
