Subject: [PATCH bpf-next 0/5] nfp: bpf: adjust head support
Date: Thu, 14 Dec 2017 21:29:14 -0800 [thread overview]
Message-ID: <20171215052919.18343-1-jakub.kicinski@netronome.com> (raw)
Hi!
This small set adds support for bpf_xdp_adjust_head() to the offload.
Since we have access to unmodified BPF bytecode translating calls is
pretty trivial. First part of the series adds handling of BPF
capabilities included in the FW in TLV format. The last two patches
add adjust head support in the nfp verifier and jit, and a small
optimization in case we can guarantee the constant adjustment
will always meet adjustment constaints.
Jakub Kicinski (5):
nfp: add nfp_cpp_area_size() accessor
nfp: bpf: prepare for parsing BPF FW capabilities
nfp: bpf: prepare for call support
nfp: bpf: add basic support for adjust head call
nfp: bpf: optimize the adjust_head calls in trivial cases
