From f845a648b8cb0435aa6323f58fac50792bbe1163 Mon Sep 17 00:00:00 2001 From: Balbir Singh Date: Thu, 6 Jul 2017 11:57:54 +1000 Subject: numa/associativity: Add a new level of NUMA for GPU's Today we have an issue where the NUMA nodes corresponding to GPU's have the same affinity/distance as normal memory nodes. Our reference-points today supports two levels [0x4, 0x4] for normal systems and [0x4, 0x3] for Power8E systems. This patch adds a new level [0x4, X, 0x2] and uses node-id as at all levels for the GPU.
