From f6f49dda49db72e7a0b4ca32c77391d5ff5ce232 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 14 Jun 2024 13:48:26 -0400 Subject: 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.
