From f7e232de51bb1b45646e5b7dc4ebcf13510f2630 Mon Sep 17 00:00:00 2001 From: Lijo Lazar Date: Wed, 6 Mar 2024 17:05:07 +0530 Subject: drm/amdgpu: Fix VCN allocation in CPX partition VCN need not be shared in CPX mode always for all GFX 9.4.3 SOC SKUs. In certain configs, VCN instance can be exclusively allocated to a partition even under CPX mode.
