Subject: [PATCH 0/2] KVM: x86: fix deliver of SMIs to halted VCPUs
Date: Tue, 13 Oct 2015 12:34:06 +0200 [thread overview]
Message-ID: <1444732448-9112-1-git-send-email-pbonzini@redhat.com> (raw)
While SeaBIOS only uses synchronous SMI delivery through port 0xb2,
OVMF also uses APIC delivery, and it is buggy.
This is enough to run OVMF with SMM enabled and multiple processors,
up to a UEFI shell, but it literally takes minutes to get there.
However, the same behavior is visible with KVM disabled, so it may
be a firmware bug instead.
