Driver Programming for ConnectX-6 Dx and ConnectX-7 for OpenBSD

Infrastructure & Networking Software And Drivers SoC And SmartNIC

Hey all,
on OpenBSD, the mcx(4) driver already supports the ConnectX-6 Dx network card, though up to now it can’t use most cool features (like IPSec offloading). Are there (public / NDA) documents for the PCIe API of the chip / Adapter(s), which state how to enable / use those (and probably all) features? A full datasheet like available for intel X710 chip network cards (https://cdrdv2-public.intel.com/332464/332464_710_Series_Datasheet_v_4_1.pdf) would be great for further developing the OpenBSD driver.
regards,
suhu

hi

There’s no offical support for OpenBSD
You can contact networking-support@nvidia.com for further help

Thank you

Hey,
Thanks for your answer. I know, that there’s no Support for OpenBSD: That’s why we want to write our drive on ourselves, but we’d need a good datasheet for it.
I’ll ask the networking-support mail as you asked.
Thank you,
suhu
