From 93d64097f741f1f07a8da9d7882d0d2657d3642a Mon Sep 17 00:00:00 2001 From: Tim Huang Date: Fri, 23 Feb 2024 10:54:45 +0800 Subject: drm/amdgpu: reserve more memory for MES runtime DRAM This patch fixes a MES firmware boot failure issue when backdoor loading the MES firmware. MES firmware runtime DRAM size is changed to 512k, the driver needs to reserve this amount of memory in FB, otherwise adjacent memory will be overwritten by the MES firmware startup code.
