Brenden Blanco <bblanco@...>
Thanks all for attending! Please find the meeting minutes below. == Progress Updates Brenden + Ari: Made some ixgbe driver progress for early drop, changes are visible at: https://git.kernel.org/cgit/linux/kernel/git/ast/bpf.git/commit/?h=xdp Early results Alexei: working on e1000 - for debugging and exploration validates the portability expectations driver supports only 1 tx queue, will need to think of more options note: 1 page per packet is nice to code against, but stressful on page allocator two people working on bpf use cases: - ila router - load balancer == Discussion Need to discuss writable rx pages map as bidir before populating rx queue? <not per dma documentation> driver specific quirk perhaps? Jesper: allocating page now >200 cycles (too high) Tom: XDP summit June 23 - invite only but no real restrictions, send Tom an email intended to be prior to netfilter so that the discussion can carry over XDP restriction: packet in memory should be as-is - no vlan stripping or other HW offload John: to share some thoughts on hardware abstraction == XDP summit topics encryption/decryption engine - problems to solve? - whats packet flow? - more generically: how to model coprocessors (regex, crypto, etc.) for bpf consumption == Misc Netronome pushed bpf offload to netdev - very nice patch set, culmination of year or so of effort XDP goal: to have at least one non-linux effort in progress to vet api maybe bpf offload is first candidate Attendees: Ari Daniel Hannes Jesper Zaafar Deepa Pere Brenden Tom Alexei Shehzad Uri John F Billy O'Mahony
