Re: [gem5-users] DPRINTF statements in gem5

[girija sameera]

Thank you for the reply. I am trying to identify where I can obtain the
core ids of the different processors involved while using
MOESI_CMP_directory protocol in X86 . For this I thought a viable approach
would be to print different variables that I'll find in the files . Which
flag should I use for this ?

P.S. I would love to hear if there could be other approaches to finding
these ids.

Thank you
K Girija Sameera

 Hello,

 You can turn on the debugging flags when you execute gem5. See this
 http://www.m5sim.org/Trace_Based_Debugging

 Note: Also you must be running a version of gem5 that has debugging
 support. See the table of gem5 binaries:

[Andreas Hansson]

Hi Prathap.

Have a look at src/proto/packet.proto. The ASCII output is not really intended 
to be used for anything besides “checking”.

The fields in the trace correspond to the enums in src/mem/packet.hh and 
src/mem/request.hh

Hello Users,

I am analyzing the memory access pattern of a benchmark. For which i have 
connected the communication monitor between cpu and dcache and obtained the

Here i could see some packet are marked with  commands 'u'(not read nor write). 
What does this mean?
Also i am trying to understand the flag values(66, 74, 2097218). Can anyone 
help me in understanding what do these flag values indicate?

Re: [gem5-users] DPRINTF statements in gem5

[kassan unda]

Open one of the files and look for a Dprintf statement. It should be good
enough to understand how to put one by yourself. You have to use a flag
with it and use that flag with the --debug-flags option. You can also use
your custom flag if you want.

Yes, you can. Use the debugging flags when running gem5 as mentioned here:
