From 71c30bd87ca5aa22a6c5bae611901d1376a436ad Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Wed, 25 May 2016 11:22:44 +0200 Subject: [PATCH] nvc0: add descriptions for hardware perf counters/metrics The GALLIUM_HUD does not yet expose a description for each events, but this might be useful for developers who want to have a long description of hw perf counters directly in the source code.
