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 --- cpu/simple_cpu/simple_cpu.hh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'cpu/simple_cpu/simple_cpu.hh') diff --git a/cpu/simple_cpu/simple_cpu.hh b/cpu/simple_cpu/simple_cpu.hh index 61c9143ba..6ad831218 100644 --- a/cpu/simple_cpu/simple_cpu.hh +++ b/cpu/simple_cpu/simple_cpu.hh @@ -216,7 +216,7 @@ class SimpleCPU : public BaseCPU assert(old_status == Idle || old_status == DcacheMissStall || old_status == IcacheMissComplete); - if (old_status == Idle) + if (old_status == Idle && curTick != 0) idleCycles += curTick - last_idle; if (tickEvent.squashed()) -- cgit v1.2.3
