Subject: [PATCH] drm/amdgpu: allow multipipe policy on ASICs with one MEC
Git-commit: dc88063b87775971be564d79dc1b05f7b8b5c135
Patch-mainline: v6.2-rc5
References: bsc#1206843
Always enable multipipe policy on ASICs with GC VERSION > 9.0.0
instead of MEC number > 1.
This will allow multipipe policy on ASICs with one MEC,
e.g., gfx11 APUs.
