From a3b17575512f0bb614234ab1834b7b36e1124082 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Fri, 16 Oct 2015 10:21:44 +0200 Subject: nvc0: add a note about MP counters on GF100/GF110 MP counters on GF100/GF110 (compute capability 2.0) are buggy because there is a context-switch problem that we need to fix. Results might be wrong sometimes, be careful!
