From d524180b88009d9158bff7fd20f3916455e0c32c Mon Sep 17 00:00:00 2001 From: Lijo Lazar Date: Mon, 19 Dec 2022 17:39:42 +0530 Subject: [PATCH] drm/amdgpu: Fix GFX v9.4.3 EOP buffer allocation Each compute cluster gets 8 compute queues in GFX v9.4.3. Fix the EOP buffer allocation so that compute queue on every XCC gets a unique address.
