Indeed - great to see some of the thought going into this area of the
project :)
If I make any progress on the actual HW I'll be sure to let you know.

Hi Armin, thanks for pointing me in the right direction.
If minimark.py docstring is up to date, looks like it will do close to
the right thing on arm5/9.
Some of the older arms don't have L2 cache, I'm not sure what
/proc/cpuinfo reports in this case, perhaps L1 cache size or nothing.
It seems i

Yes, it does in PyPy; we do a full collection when the tot
Oh, I guessed your reasons.
Lanugages like python make a lot of garbage, so 16MB will fill up
pretty fast as long as the program does something at all. What I mean
to say is that there's gotta be a more clever way where gc thresholds
depend on e.g. size of working set or rate of new allocations or

I think that you are saying something wrong: "no jit + our own GC +
the shadowstack gc root finder" should get you p
Hi David, thanks for the quick response.

Hi - I've been looking at pypy as a possible application runtime in an ARM9
Linux based system. I understand that the in-progress ARM jit backend targets
only ARMv7, but I'm still interested in characterizing a translated pypy-c
interpreter on this system with regard to CPU and memory usage. Of
