From 83edf00d8972eecd849865a34bd4fada09444ec4 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 14 Jun 2024 13:48:26 -0400 Subject: [PATCH] drm/amdgpu/atomfirmware: fix parsing of vram_info v3.x changed the how vram width was encoded. The previous implementation actually worked correctly for most boards. Fix the implementation to work correctly everywhere. This fixes the vram width reported in the kernel log on some boards.
