[Discuss-gnuradio] ps3 kernel upgrade

[Chuck Swiger]

Eric et al - Obtained and installed CELL-Linux-CL_20080609-ADDON.iso  
with the kernel 2.6.25.4, bad news is it still does not have the nfs  
modules. The good news is with 220MB free memory compiling on the ps3  
isn't too slow - I had two windows compiling different parts and swap  
was rarely being used. The bad news is make check still segfaults on  
qa_gcell_wrapper. The good news is the offload stuff still basically  
works and playing with benchmark_nop really makes sense now. Running  
1000uSec of nops per thread, using 1000 threads on one SPU takes just  
about a second. Running 2000 threads on 2 SPU takes just about a  
second. 6000 threads on 6 SPU takes about a second. Using 500uSec of  
nop, 12000 threads on 6 SPU takes about one seconds, etc, etc, etc.

The benchmark_* examples look like a good jumping off place for using  
the gcell tools with ones own spu code.
