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.hh | 16 ++++++++++++++-- 1 file changed, 14 insertions(+), 2 deletions(-) (limited to 'base/statistics.hh') diff --git a/base/statistics.hh b/base/statistics.hh index 2fe6988b0..aa3489727 100644 --- a/base/statistics.hh +++ b/base/statistics.hh @@ -60,6 +60,9 @@ #include #include "sim/host.hh" +#ifdef FS_MEASURE +#include "base/trace.hh" +#endif // // Un-comment this to enable weirdo-stat debugging // @@ -2167,6 +2170,7 @@ class GenBin : public Detail::BinBase virtual ~GenBin() {}; virtual void activate() = 0; + virtual std::string name() const = 0; void regBin(GenBin *bin, std::string name); }; @@ -2198,7 +2202,6 @@ struct StatBin : public GenBin // That one is for the last trailing flags byte. offset() += (size + 1 + mask) & ~mask; - return off; } @@ -2212,7 +2215,12 @@ struct StatBin : public GenBin return Detail::BinBase::memory() + off; } - virtual void activate() { setCurBin(this); } + virtual void activate() { + setCurBin(this); +#ifdef FS_MEASURE + DPRINTF(TCPIP, "activating %s Bin\n", name()); +#endif + } static void activate(StatBin &bin) { setCurBin(&bin); } class BinBase @@ -2426,7 +2434,11 @@ struct NoBin * is NoBin, nothing is binned.
