From 0b4ea45e8aded79557da3a51bb88c9bbacfa07dc Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Tue, 3 Nov 2009 19:47:51 +0000 Subject: util: Remove homegrown Windows KM profiler. It's not sampling based so its results are biased towards functions called many times. --- src/gallium/auxiliary/util/u_debug_profile.c | 320 --------------------------- 1 file changed, 320 deletions(-) delete mode 100644 src/gallium/auxiliary/util/u_debug_profile.c (limited to 'src/gallium/auxiliary/util/u_debug_profile.c') diff --git a/src/gallium/auxiliary/util/u_debug_profile.c b/src/gallium/auxiliary/util/u_debug_profile.c deleted file mode 100644 index d765b50144..0000000000 --- a/src/gallium/auxiliary/util/u_debug_profile.c +++ /dev/null @@ -1,320 +0,0 @@ -/************************************************************************** - * - * Copyright 2008 Tungsten Graphics, Inc., Cedar Park, Texas. - * All Rights Reserved. - * - * 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, sub license, 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 (including the - * next paragraph) 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 NON-INFRINGEMENT. - * IN NO EVENT SHALL TUNGSTEN GRAPHICS AND/OR ITS SUPPLIERS BE LIABLE FOR - * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, - * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE - * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. - * - **************************************************************************/ - -/** - * @file - * Poor-man profiling. - * - * @author José Fonseca - * - * @sa http://blogs.msdn.com/joshpoley/archive/2008/03/12/poor-man-s-profiler.aspx - * @sa http://www.johnpanzer.com/aci_cuj/index.html - */ - -#include "pipe/p_config.h" - -#if defined(PROFILE) && defined(PIPE_SUBSYSTEM_WINDOWS_DISPLAY) - -#include -#include - -#include "util/u_debug.h" -#include "util/u_string.h" - - -#define PROFILE_TABLE_SIZE (1024*1024) -#define FILE_NAME_SIZE 256 - -struct debug_profile_entry -{ - uintptr_t caller; - uintptr_t callee; - uint64_t samples; -}; - -static unsigned long enabled = 0; - -static WCHAR wFileName[FILE_NAME_SIZE] = L"\\??\\c:\\00000000.prof"; -static ULONG_PTR iFile = 0; - -static struct debug_profile_entry *table = NULL; -static unsigned long free_table_entries = 0; -static unsigned long max_table_entries = 0; - -uint64_t start_stamp = 0; -uint64_t end_stamp = 0; - - -static void -debug_profile_entry(uintptr_t caller, uintptr_t callee, uint64_t samples) -{ - unsigned hash = ( caller + callee ) & PROFILE_TABLE_SIZE - 1; - - while(1) { - if(table[hash].caller == 0 && table[hash].callee == 0) { - table[hash].caller = caller; - table[hash].callee = callee; - table[hash].samples = samples; - --free_table_entries; - break; - } - else if(table[hash].caller == caller && table[hash].callee == callee) { - table[hash].samples += samples; - break; - } - else { - ++hash; - } - } -} - - -static uintptr_t caller_stack[1024]; -static unsigned last_caller = 0; - - -static int64_t delta(void) { - int64_t result = end_stamp - start_stamp; - if(result > UINT64_C(0xffffffff)) - result = 0; - return result; -} - - -static void __cdecl -debug_profile_enter(uintptr_t callee) -{ - uintptr_t caller = last_caller ?
