From bbcc3514ab4f7ec3ae2273ad08b0a1b6b4aa9dd9 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Fri, 2 Jun 2023 07:18:06 -0500 Subject: [PATCH] drm/amd: Check that a system is a NUMA system before looking for SRAT It's pointless on laptops to look for the SRAT table as these are not NUMA. Check the number of possible nodes is > 1 to decide whether to look for SRAT.
