From 921b1ee87b6927e7310c747e03efd223d8c65642 Mon Sep 17 00:00:00 2001 From: Lisa Hsu Date: Tue, 4 Nov 2003 15:15:12 -0500 Subject: Add the ability to track stats in user defined sets of function calls. code can be generated via the base/instrum_codegen.pl script to easily change the functions being tracked. the only thing the user needs to do is add code in tru64System to change how the callerMap is populated. command line: m5.* --server.system:bin=true to track function calls in the server m5.* --client.system:bin=true to track function calls in the client base/statistics.cc: make an adjustment to the way stats are printed for FS_MEASURE base/statistics.hh: add a name() virtual function to GenBin. add a debug printf for activate(). add amake MainBin the default bin when FS_MEASURE. cpu/exec_context.cc: initialize swCtx to null upon creation of an xc cpu/exec_context.hh: add a SWContext pointer to every execution context. cpu/simple_cpu/simple_cpu.cc: process calls and returns for FS_MEASURE cpu/simple_cpu/simple_cpu.hh: add this so idleCycles will not be accessed before all stats are constructed kern/tru64/tru64_events.cc: add a FnEvent that fires whenever a function we're tracking is called. implement the process() virtual function for it. kern/tru64/tru64_events.hh: add FnEvent kern/tru64/tru64_system.cc: send bin parameter to System constructor. add bin parameter to Tru64System object. initialize all the FnEvent and MainBin members of Tru64system. also, populate the calling map that indicates whether a function call is on the path we're tracking. kern/tru64/tru64_system.hh: modify the Tru64System class to support FS_MEASURE sim/system.cc: add a bin parameter to System class. initialize a MainBin to hold the stats for nonPath. sim/system.hh: add a map of to match bins to function names. add a swCtx map to map pcb addresses to SWContext *s. Add some supporting functions. --HG-- extra : convert_revision : af3eadd798cb2d2aed9b54e1059dcedf244dd526 --- base/statistics.cc | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'base/statistics.cc') diff --git a/base/statistics.cc b/base/statistics.cc index c1a5b2626..fbb056498 100644 --- a/base/statistics.cc +++ b/base/statistics.cc @@ -161,6 +161,7 @@ void Database::dump(ostream &stream) { +#ifndef FS_MEASURE list_t::iterator i = printStats.begin(); list_t::iterator end = printStats.end(); while (i != end) { @@ -169,6 +170,7 @@ Database::dump(ostream &stream) binnedStats.push_back(stat); ++i; } +#endif //FS_MEASURE list::iterator j = bins.begin(); list::iterator bins_end=bins.end(); @@ -183,8 +185,13 @@ Database::dump(ostream &stream) panic("a binned stat not found in names map!"); ccprintf(stream,"---%s Bin------------\n", (*iter).second); +#ifdef FS_MEASURE + list_t::iterator i = printStats.begin(); + list_t::iterator end = printStats.end(); +#else list_t::iterator i = binnedStats.begin(); list_t::iterator end = binnedStats.end(); +#endif while (i != end) { Stat *stat = *i; if (stat->dodisplay()) @@ -194,9 +201,16 @@ Database::dump(ostream &stream) ++j; ccprintf(stream, "---------------------------------\n"); } +#ifndef FS_MEASURE ccprintf(stream, "**************ALL STATS************\n"); +#endif } +/** + * get bin totals working, then print the stat here (as total), even if + * its' binned.
