From 1f9d56c30939757cc4ea63030c329fb54d001136 Mon Sep 17 00:00:00 2001 From: Huang Rui Date: Wed, 1 Jul 2020 09:37:56 +0800 Subject: [PATCH] drm/amdgpu: add register distance members into vmhub structure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch is to abstract register distances between two continuous context domains and invalidation engines. In different ip headers, these distances may be differences.
