Hello all,
I’m simulating a single core system with Ruby, using the MESI_Two_Level
protocol. I need to measure the number of L1 load misses. To do so, I’m summing
up these two statistics:
system.ruby.L1Cache_Controller.NP.Load
system.ruby.L1Cache_Controller.I.Load
I would expect the resulting
Hello,
As far as I know, TLB misses are not modeled in SE mode at all.
Cheers,
Jason

Hi Jason! Thanks for the info!
Do you know what is happening when there is a TLB miss in SE mode?
Is the latency of a TLB miss modeled in some way in SE?

Hi Leon,
I believe you're correct. When there is a TLB hit, it's up to the *CPU
model* to model the latency of the TLB access. I think this implementation
was designed this way to give flexibility to the CPU models. Since the TLB
is deeply embedded in the pipeline, we wouldn't want to always have
Hi Leon,
This is exactly what gem5's region of interest (ROI) markers are for. You
can use these "special instructions" as either magic instructions (using
unused opcodes in the ISA) or as memory-mapped IO (useful for KVM CPUs).
You can embed these markers in your program by calling the m5ops
Hi all,
I've been wondering if there's a way to measure how many ticks a particular
part of process costs. I usually do this by hedging code blocks around with
printf's that contain curTick() and then observing the output. But other than
that, perhaps a better way exists? (ticks only, ie not
Thank you very much, Boris.
Let me have a try with it.

If your question is, "How do I apply the patch", first you need to
fetch it to your local Git clone:
git fetch https://gem5.googlesource.com/public/gem5 refs/changes/85/44685/3
and then
