Re: [microblaze-uclinux] checksum offload and zero-copy with ll_temac on ML505
On Fri, Mar 13, 2009 at 7:01 PM, <Guillaume.Gastebois@xxxxxxxxxxxxxxxxxxx>
I want to do 500Mbps with microblaze.
I can do it with Xilinx ML505 TCP/IP Treck stack reference design.
This reference design use zerocopy and
checksum offload optimizations.
Is it possible to do so with petalinux
? I try enabling checksum offload in petalinux ML505 no MMU ll_temac reference
design but without performance emprovement (less than 20Mbps) !!
We have not done any performance optimisation on the ll_temac driver, but I suspect there are some good opportunities for improvement. We have many competing priorities at the moment, but if you can find any information about performance bottlenecks we can talk to you about ways around them.
