[Qemu-devel] [PATCH 0/2] Enable QEMU to control MPIDR values

Posted by Andrew Jones 8 years, 8 months ago

Igor needs to know/select vcpu MPIDR values early in order to map vcpus
to vnodes. Waiting until after vcpu init, when KVM sets them, is too
late. With this patch, and its KVM counterpart, QEMU can control the
values, allowing it to know/select them whenever it likes.
