Subject: [PATCH v2 0/2] bpf/arm64: support packet data load instructions
Date: Thu, 19 Mar 2026 12:44:07 +0100 [thread overview]
Message-ID: <20260319114500.9757-1-cfontain@redhat.com> (raw)
In-Reply-To: <20260310122045.4057836-1-cfontain@redhat.com>
v2:
- use emit_return_zero_if_src_zero instead of manual call
- add fast path (direct read from mbuf->buf_addr) if the
requested data is present in the first mbuf and fallback to
'slow path' (call to __rte_pktmbuf_read) otherwise.
- add tests for BPF_LD ABS/IND amd slow path.
