[Qemu-devel] [PATCH v3 1/4] hw/arm/xlx-zynqmp: Realize cluster after putting RPUs in it
Posted by Peter Maydell 6 years, 9 months ago
Currently the cluster implementation doesn't have any constraints
on the ordering of realizing the TYPE_CPU_CLUSTER and populating it
with child objects. We want to impose a constraint that realize
must happen only after all the child objects are added, so move
the realize of rpu_cluster. (The apu_cluster is already
realized after child population.)
