[ECOS] Enabling -O2 option of GCC]
Mon Dec 10 08:04:00 GMT 2001
i added volatile modifier to buffer descriptor pointers.
it is working fine.
i am working on a 8260 based board, where i am getting a avg.
latency of 0.7 ms for ping,
with cache, MMU and optimisations enabled.
i want to reduce the latency to about tens of micro secs. (required
by our application).
Any idea where to optimize? Has anybody done away with the memory
copy from the ethernet buffers to the mbufs ?
thanx in advance,
