From f42fb0012a04576884f7dcf227df640ed60d9655 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 9 May 2017 15:47:12 +1000 Subject: [PATCH] r600/eg: add support for tracing IBs after a hang. This is a poor man's version of radeonsi ddebug stuff, this should get hooked into that infrastructure, and grow more stuff, but for now, just create R600_TRACE var that points to a file that you want to dump the last IB to.
