From 49aa98ca30cd186ab33fc5802066e2024d3bfa39 Mon Sep 17 00:00:00 2001 From: Yongqiang Sun Date: Wed, 30 Mar 2022 10:48:19 -0400 Subject: [PATCH] drm/amd/amdgpu: Only reserve vram for firmware with vega9 MS_HYPERV host. driver loading failed on VEGA10 SRIOV VF with linux host due to a wide range of stolen reserved vram. Since VEGA10 SRIOV VF need to reserve vram for firmware with windows Hyper_V host specifically, check hypervisor type to only reserve memory for it, and the range of the reserved vram can be limited to between 5M-7M area.
