Hi all,
during the last week or so I did some patches to the sunrpc code that
should help reduce the number of memcpy operations we do there.
They implement
* IOAT support in the rpc client code
* TCP zerocopy in the rpc server code
Both have been lightly tested (the former severely hampered by the lack
of ioat capable hardware, which is why I had to write a "memcpy dma"
module :-)
The code is available from http://oss.oracle.com/~okir/nfs-zerocopy/
Please let me know what you think.
Olaf
