From a81c03737addc8e9a9b00cde0354e6c0ab4561af Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Tue, 18 Oct 2005 19:07:42 -0400 Subject: [PATCH] Add new function profiling stuff, wrap the pc_sample stuff into it. SConscript: Get rid of the pc_sample stuff and move to the new profiling stuff base/traceflags.py: DPRINTF Stack stuff cpu/base.cc: cpu/base.hh: cpu/exec_context.cc: cpu/exec_context.hh: cpu/simple/cpu.cc: Add profiling stuff kern/kernel_stats.hh: Use a smart pointer sim/system.cc: sim/system.hh: Create a new symbol table that has all of the symbols for a particular system util/stats/categories.py: change around the categories, add categories for function profiling stuff util/stats/profile.py: No profile parsing and display code to deal with function profiling stuff, graph, dot, and text outputs. --HG-- extra : convert_revision : b3de0cdc8bd468e42647966e2640ae009bda9eb8 --- SConscript | 4 +- arch/alpha/stacktrace.cc | 324 ++++++++++++++++++++++ arch/alpha/stacktrace.hh | 99 +++++++ base/traceflags.py | 3 +- cpu/base.cc | 42 +++ cpu/base.hh | 17 ++ cpu/exec_context.cc | 38 ++- cpu/exec_context.hh | 9 +- cpu/profile.cc | 147 ++++++++++ cpu/profile.hh | 74 +++++ cpu/simple/cpu.cc | 23 +- kern/kernel_stats.hh | 5 +- sim/system.cc | 16 ++ sim/system.hh | 3 + util/stats/categories.py | 575 +++++++++++++++++++++++---------------- util/stats/profile.py | 484 +++++++++++++++++++++++++++----- 16 files changed, 1533 insertions(+), 330 deletions(-) create mode 100644 arch/alpha/stacktrace.cc create mode 100644 arch/alpha/stacktrace.hh create mode 100644 cpu/profile.cc create mode 100644 cpu/profile.hh diff --git a/SConscript b/SConscript index 4e2347431..de320aa40 100644 --- a/SConscript +++ b/SConscript @@ -143,7 +143,6 @@ base_sources = Split(''' encumbered/cpu/full/issue.cc encumbered/cpu/full/ls_queue.cc encumbered/cpu/full/machine_queue.cc - encumbered/cpu/full/pc_sample_profile.cc encumbered/cpu/full/pipetrace.cc encumbered/cpu/full/readyq.cc encumbered/cpu/full/reg_info.cc @@ -241,6 +240,7 @@ full_system_sources = Split(''' arch/alpha/ev5.cc arch/alpha/osfpal.cc arch/alpha/pseudo_inst.cc + arch/alpha/stacktrace.cc arch/alpha/vtophys.cc base/crc.cc @@ -248,6 +248,7 @@ full_system_sources = Split(''' base/remote_gdb.cc cpu/intr_control.cc + cpu/profile.cc dev/alpha_console.cc dev/baddev.cc @@ -345,6 +346,7 @@ targetarch_files = Split(''' isa_traits.hh osfpal.hh pseudo_inst.hh + stacktrace.hh vptr.hh vtophys.hh ''') diff --git a/arch/alpha/stacktrace.cc b/arch/alpha/stacktrace.cc new file mode 100644 index 000000000..fdad9d673 --- /dev/null +++ b/arch/alpha/stacktrace.cc @@ -0,0 +1,324 @@ +/* + * Copyright (c) 2005 The Regents of The University of Michigan + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are + * met: redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer; + * redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution; + * neither the name of the copyright holders nor the names of its + * contributors may be used to endorse or promote products derived from + * this software without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS + * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT + * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR + * A PARTICULAR PURPOSE ARE DISCLAIMED.
