Subject: [PATCH net-next v2 0/4] arm64 BPF JIT updates
Date: Mon, 6 Jun 2016 22:22:55 -0700 [thread overview]
Message-ID: <1465276979-10147-1-git-send-email-zlim.lnx@gmail.com> (raw)
Updates for arm64 eBPF JIT.
The main addition here is implementation of bpf_tail_call.
#1: Fix missing header inclusion in linux/bpf.h.
#2: Add bpf_tail_call for arm64.
#3,4: Optimizations to reduce instruction count for jitted code.
Changes since v1:
- Added patch #1 to address build error due to missing header inclusion
in linux/bpf.h. (Thanks to suggestion and ack by Daniel Borkmann)
Ordered it ahead of bpf_tail_call patch #2 so build error is not
triggered.
Zi Shen Lim (4):
bpf: fix missing header inclusion
arm64: bpf: implement bpf_tail_call() helper
arm64: bpf: optimize JMP_CALL
arm64: bpf: optimize LD_ABS, LD_IND
