From 698825653fdf1a696e1b9458ed9fc4aa2c6587d4 Mon Sep 17 00:00:00 2001 From: Christian König Date: Fri, 19 Jan 2018 14:17:40 +0100 Subject: drm/amdgpu: add optional ring to *_hdp callbacks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This adds an optional ring to the invalidate_hdp and flush_hdp callbacks. If the ring isn't specified or the emit_wreg function not available the HDP operation will be done with the CPU otherwise by writing on the ring.
