Subject: [PATCH 0/6] eBPF JIT for PPC64
Date: Tue, 7 Jun 2016 19:02:17 +0530 [thread overview]
Message-ID: <cover.1465304785.git.naveen.n.rao@linux.vnet.ibm.com> (raw)
Implement extended BPF JIT for ppc64. We retain the classic BPF JIT for
ppc32 and move ppc64 BE/LE to use the new JIT. Classic BPF filters will
be converted to extended BPF (see convert_filter()) and JIT'ed with the
new compiler.
Most of the existing macros are retained and fixed/enhanced where
appropriate. Patches 1-4 are geared towards this.
Patch 5 breaks out the classic BPF JIT specifics into a separate
bpf_jit32.h header file, while retaining all the generic instruction
macros in bpf_jit.h.
Patch 6 implements eBPF JIT for ppc64.
Since the RFC patchset [1], powerpc JIT has now gained support for skb
access helpers and now passes all tests in test_bpf.ko. Review comments
on the RFC patches have been addressed (use of an ABI macro [2] and use
of bpf_jit_binary_alloc()), along with a few other generic fixes and
updates.
Prominent TODOs:
- implement BPF tail calls
- support for BPF constant blinding
Please note that patch [2] is a pre-requisite for this patchset, and is
not yet upstream.
