and if you have SX-optimized software (XIL pipelines, etc) you should
reserve some of your memory for the SX to use.  it requires a chunk
of physically-contiguous memory for best operation since it operates
on physical, not virtual, addresses.  the sx_cmem kernel module did
that and you really only got excellent performance using the graphics
plug-ins (XIL pipelines, etc.) that made use of sx_cmem.  there was a
sxconfig program that would set it up for you.  refer to the man page
for details.

SuperSPARC-only modules also did a better (at least until processors
faster than 60MHz showed up) since having the SuperCACHE would add a
cycle or two of latency to the MBus accesses which is how you talk
to the cg14.
