ixy.hs is a Haskell rewrite of the ixy userspace network driver.
It is designed to be readable, idiomatic Haskell (as far as possible).
It supports Intel 82599 10GbE NICs (ixgbe family of devices).
- currenty less than 1500 lines of Haskell for a working driver
- relatively simple to use API
- documented code
Install stack by whatever means.
Make sure to libpcre3-dev is installed, otherwise execute (or equivalent):
apt install libpcre3-dev
Ixy.hs needs hugepages to work. To allocate some use the provided script setup-hugetlbfs.sh:
sudo ./setup-hugetlbfs.sh
You can then build binaries with stack build or run the forwarder application directly by using
stack run.
The build binaries can be found in
.stack-work/dist/x86_64-linux-tinfo6/Cabal-2.2.0.1/build/forwarder/forwarder.
The PCI addresses of the devices must currently be changed in code.
src/Lib.hs defines ixy.hs's public API.
Docs can be generated with the command stack haddock --haddock-internal
ixy.hs is licensed under the MIT license.
ixy.hs is not production-ready. Do not use it in critical environments. DMA may corrupt memory.
