From bbb860d46fcbde5881c93ed549445a85f2434a64 Mon Sep 17 00:00:00 2001 From: Yifan Zha Date: Wed, 17 Aug 2022 17:25:15 +0800 Subject: [PATCH] drm/amdgpu: Use RLCG to program GRBM_GFX_CNTL during full access time MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [Why] KIQ register init requires GRBM_GFX_CNTL to select KIQ. [How] As RLCG accessing registers will save the data of GRBM_GFX_CNTL and restore it. Use RLCG indirect accessing register method to select grbm instead of mmio directly access.
