From 5dad5274a2861f59941f1b57a751891a435d804c Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Fri, 9 Jan 2015 18:58:16 +0100 Subject: [PATCH 2/2] smbios: Don't report unknown CPU speed (fix SVVP regression) Message-id: <1420829896-30146-3-git-send-email-ehabkost@redhat.com> Patchwork-id: 63234 O-Subject: [RHEV-7.1 qemu-kvm-rhev PATCH 2/2] smbios: Don't report unknown CPU speed (fix SVVP regression) Bugzilla: 1177127 RH-Acked-by: Gerd Hoffmann RH-Acked-by: Paolo Bonzini RH-Acked-by: Laszlo Ersek SVVP requires processor speed on Type 4 structures to not be unknown. This was fixed in SeaBIOS 0.5.0 (in 2009), but the bug was reintroduced in QEMU 2.1. Revert to old behavior and report CPU speed as 2000 MHz instead of unknown.
