Re: [gem5-users] m5ops with RISCV

[Vanchinathan Venkataramani]

Dear Alec

Thanks a lot for your prompt reply. I looked at the CSR counters and it
looks to me that I cannot find number of integer, load, store instructions
executed separately.

Ideally, if I can reset and dump stats using m5_dumpstats and
m5_resetstats, I can get detailed information on instruction executed per
type in one go. But now this is not available. Is there *any tutorial* that
can be used for *implementing* this?

Thanks a lot once again.

Hi Vanchinathan,

At the moment, there is not a patch for m5op support for RISC-V.  If you
want binaries to have access to performance counts, the best way to do that
would probably be to add CSRs for them and have those CSRs return the
values of the corresponding stats when read, like INSTRET, CYCLE, and TIME
do.
