support for latest version of io_engine/kernel 3.x ?

[rohitjoshi]

Any plan to integrate latest version of io_engine which supports Linux kernel 3.x?

At the moment we don't have plans of upgrading the ioengine driver (for linux versions 3.0 and above). The PSIO engine driver is managed by another team. You can try contacting them: https://github.com/ANLAB-KAIST/Packet-IO-Engine

@ajamshed thanks. I was able to successfully build latest version of package-io-engine on 3.x kernel but due to some interface changes, mTCP fails to link.

Hi Rohit,

Apologies for the delayed response. I just went through mTCP's psio driver file (ixgbe_main.c) and it looks like the missing function should be: ps_select(). You may have to patch up the 3.x version of the driver with this function. Also, please verify that the 3.x version, as it is, works fine. You may want to run pspgen traffic generator (available from anlab GitHub) to see if the driver is running well.
