Sorry about that; I hope that people finding that thread later on read the
followup post where I stand corrected.

Hi Dave,
There isn't a limit on the number of pending page walks.
At least for ARM only a single walk can be active at a time. Because the
walk does take time, back pressure is applied to the CPU, but the CPU
can request as many as it would like. Since this original posting, a bug
was fixed in
Hello,
Paul referred to gem5 not being able to put backpressure on the CPU from the
main memory, citing this topic;

According to this post there is no limit to the number of concurrent page
walks. Do page walks go through the mai

Just a clarification on Paul's second point: the issue described in the
email he's linked to strictly refers to backpressure for TLB misses (i.e.,
pagetable walks). There definitely is backpressure on the CPU for regular
memory accesses.

As someone who has used (and tried to modify) both marssx86 and gem5, I
would like to add one (potential) benefit to the marssx86 side of things:
the emulation mode (via QEMU) allows you to boot the system very quickly up
to a region of interest and take a checkpoint right before the simulation

Hello,
What is the difference between gem5
http://gem5.org/Main_Page
and MARSS (Micro-ARchitectural and System Simulator for x86-based Systems)

As far as I can tell,
-gem5 can support Alpha, ARM, SPARC, and x86 instruction set architectures,
whereas MAR
