From 4cd1cfb9831d4d4081cbe80b0d72b340c8fd0c2c Mon Sep 17 00:00:00 2001 From: Christoph Bumiller Date: Fri, 4 Jul 2014 13:02:06 +0200 Subject: [PATCH] st/mesa: implement GL_AMD_performance_monitor This is based on the original patch of Christoph Bumiller. v2 (Samuel Pitoiset): - improve Gallium interface for this extension - rewrite some parts of the original code - fix compilation errors and piglit tests v3: - only enable this extension when the underlying driver expose GPU counters - get rid of the ring buffer of queries v4: - add a debug message when the maximum number of counters has been reached Signed-off-by: Samuel Pitoiset Reviewed-by: Martin Peres --- src/mesa/Makefile.sources | 2 + src/mesa/state_tracker/st_cb_perfmon.c | 425 +++++++++++++++++++++++++++++++++ src/mesa/state_tracker/st_cb_perfmon.h | 64 +++++ src/mesa/state_tracker/st_context.c | 9 + 4 files changed, 500 insertions(+) create mode 100644 src/mesa/state_tracker/st_cb_perfmon.c create mode 100644 src/mesa/state_tracker/st_cb_perfmon.h diff --git a/src/mesa/Makefile.sources b/src/mesa/Makefile.sources index 1293d41..83f500f 100644 --- a/src/mesa/Makefile.sources +++ b/src/mesa/Makefile.sources @@ -434,6 +434,8 @@ STATETRACKER_FILES = \ state_tracker/st_cb_flush.h \ state_tracker/st_cb_msaa.c \ state_tracker/st_cb_msaa.h \ + state_tracker/st_cb_perfmon.c \ + state_tracker/st_cb_perfmon.h \ state_tracker/st_cb_program.c \ state_tracker/st_cb_program.h \ state_tracker/st_cb_queryobj.c \ diff --git a/src/mesa/state_tracker/st_cb_perfmon.c b/src/mesa/state_tracker/st_cb_perfmon.c new file mode 100644 index 0000000..4bde679 --- /dev/null +++ b/src/mesa/state_tracker/st_cb_perfmon.c @@ -0,0 +1,425 @@ +/* + * Copyright (C) 2013 Christoph Bumiller + * Copyright (C) 2015 Samuel Pitoiset + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
