X-Spam-Level:
The GCC folks have recently started using the HW_PHYSMEM and HW_USERMEM
sysctl MIB nodes to tune the behavior of the garbage collecting memory
allocator in GCC. It was pointed out there that these totally fall over
with >=4G of RAM, since it's a 32-bit quantity that returns the number
of bytes.
I'd like to propose new HW_PHYSPAGES and HW_USERPAGES MIB nodes that
return the same information, but in a 32-bit page count, instead. The
implementation is left as an exercise to the reader. I just want to get
consensus on the names, so that I can tell the GCC people about it, and
have it work on all the BSD platforms (as their current sysctl code does).
