OPENED Tool for Managing eBPF Heterogeneity

on YouTube ↗33m

" summary

Prototype extracts a developer-selected eBPF function from large repos using CodeQuery (cscope/ctags), TXL annotations and Python to dump a minimal extracted.c, then applies source-to-source rules (Coccinelle/TXL) to transform XDP to TC and adjust helpers and headers. Current 425 LoC C++ prototype implements seven transformation rules, validates on xdp-tutorial, Mizar, Suricata XDP filter and Meta’s Katran, compiles, passes the kernel verifier and loads; largest case (Katran) transforms in ~500ms but still requires user disambiguation for duplicate symbols.
