From d7a6634a4cfba073ff6a526cb4265d6e58ece234 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 25 Jun 2020 17:55:57 -0400 Subject: [PATCH] drm/amdgpu/atomfirmware: fix vram_info fetching for renoir Renoir uses integrated_system_info table v12. The table has the same layout as v11 with respect to this data. Just reuse the existing code for v12 for stable. Fixes incorrectly reported vram info in the driver output.
