From bf376f3020dfd7bcb2c4158b4ffa85c04d44f56d Mon Sep 17 00:00:00 2001 From: Suravee Suthikulpanit Date: Wed, 7 Jun 2023 15:57:16 -0500 Subject: [PATCH] hw/i386/pc: Default to use SMBIOS 3.0 for newer machine models MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, pc-q35 and pc-i44fx machine models are default to use SMBIOS 2.8 (32-bit entry point). Since SMBIOS 3.0 (64-bit entry point) is now fully supported since QEMU 7.0, default to use SMBIOS 3.0 for newer machine models. This is necessary to avoid the following message when launching a VM with large number of vcpus. "SMBIOS 2.1 table length 66822 exceeds 65535" Signed-off-by: Suravee Suthikulpanit Message-Id: <20230607205717.737749-2-suravee.suthikulpanit@amd.com> Reviewed-by: Michael S.
