From 0e4edb3b3b5770ac325f5df02689154be5e64963 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Tue, 26 Oct 2021 11:11:00 -0400 Subject: hw/i386: expose a "smbios-entry-point-type" PC machine property MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The i440fx and Q35 machine types are both hardcoded to use the legacy SMBIOS 2.1 (32-bit) entry point. This is a sensible conservative choice because SeaBIOS only supports SMBIOS 2.1 EDK2, however, can also support SMBIOS 3.0 (64-bit) entry points, 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 64-bit SMBIOS entry point: $QEMU -machine q35,smbios-entry-point-type=64 Based on a patch submitted by Daniel Berrangé.
