PFqOmatic

pfq-omatic script

Pfq-omatic is a Haskell script that can be used to compile source codes of network device drivers and obtain PFQ aware versions. By overloading symbols at compile time, pfq-omatic enables:

• drivers to send packets directly to PFQ, which is then interposed between network driver and the Linux kernel.
• drivers to exploit the ad-hoc socket buffer allocator.
• software accelerations.

Example:

cd ixbge
pfq-omatic
[PFQ] pfq-omatic: v3.0
[PFQ] using /opt/PFQ/kernel/Module.symvers file (most recent)
[PFQ] ./ixgbe_main.c is already patched :)
[PFQ] compiling: make -j6...
