From 25ec40bd0617c278843b26c96bf52ef48c35b590 Mon Sep 17 00:00:00 2001 From: Tom St Denis Date: Wed, 23 Aug 2017 15:33:40 -0400 Subject: [PATCH 0003/4131] drm/amd/amdgpu: Remove AMDGPU tracepoint and use new TTM tracepoint (v2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Switches the AMDGPU driver over to the TTM tracepoint and removes our old one. Now you can enable traces before loading the module and trace all mappings.
