Subject: [Qemu-devel] [PATCH] isapc: Remove unnecessary migration compatibility code
Date: Fri, 6 Oct 2017 10:25:02 -0300 [thread overview]
Message-ID: <20171006132502.9191-1-ehabkost@redhat.com> (raw)
We don't touch isapc when we change guest ABI and add new entries
to PC_COMPAT_* or new PCMachineClass compat flags. This means
isapc never guaranteed guest ABI and cross-QEMU-version live
migration compatibility. There's no point in keeping code for
kvm-pv-eoi and APIC ID compatibility in pc_init_isa().
