Indeed there is a way to signal workbegin and workend from the program itself
with m5 ops. But I'm trying to avoid recompiling a whole bunch of code to make
it happen, though I can do that too. If there is a way to simulate workbegin
and workend from the command line great, otherwise no worries I'll implement
alternatives. Thanks for the responses!

I don't think we ever transitioned from an assembly based mechanism to a C

actually invoke the call into gem5, and C to provide a friendly
interface/wrapper around the assembly. That said, yes, it looks like work begin
and work end are just not in the utility, but they are in the header files and
are implemented in gem5 itself.
Looking at this again triggered a vague memory where I think these didn't make
sense being called from the utility for some reason? Maybe they only make sense
in SE mode, or they should be called from code directly instead of from a shell
or script? I'm not very familiar with them so I can't say for sure, but I
vaguely remember there was something like that.

Hi George,
Thanks for reporting this, I noticed the same issue. When we transitioned from
the old m5 subsystem (assembly based) to the new C based one we forgot to
provide an implementation for workbegin and workend I suppose. Putting Gabe on

Subject: [gem5-users] M5 Fs utility workbegin
Hello Gem5 community,
I'm trying to use the M5 utility meant for full system mode to signal work
begin and end. I see in the documentation that the utility supports these
parameters:
- workbegin: Cause an exit evet of type, “workbegin”, that could be used to
mark the begining of an ROI.
- workend: Cause an exit event of type, “workend”, that could be used to
mark the termination of an ROI.
But when I run the utility in X86 after compiling it for X86 those two options
aren't available as commands. There is a "fail" option with a parameter that
isn't mentioned in the documentation. Is that the way to simulate workbegin and
workend?
Thanks in advance,
George M
