[PATCH v2 2/2] spapr: Add a new level of NUMA for GPUs

2020-05-18 Thread Reza Arbab
NUMA nodes corresponding to GPU memory currently have the same affinity/distance as normal memory nodes. Add a third NUMA associativity reference point enabling us to give GPU nodes more distance. This is guest visible information, which shouldn't change under a running guest across migration betw
