From faad5ccac1eaae584f9ac2ea66278bd137edcbe3 Mon Sep 17 00:00:00 2001 From: Yongqiang Sun Date: Tue, 15 Mar 2022 09:43:41 -0400 Subject: [PATCH] drm/amdgpu: Add stolen reserved memory for MI25 SRIOV. MI25 SRIOV guest driver loading failed due to allocated memory overlaps with firmware reserved area. Allocate stolen reserved memory for MI25 SRIOV specifically to avoid the memory overlap.
