Subject: [PATCH v2 net-next 0/7] net: ethernet: ti: cpsw: Add XDP support
Date: Thu, 30 May 2019 21:20:32 +0300 [thread overview]
Message-ID: <20190530182039.4945-1-ivan.khoronzhuk@linaro.org> (raw)
This patchset adds XDP support for TI cpsw driver and base it on
page_pool allocator. It was verified on af_xdp socket drop,
af_xdp l2f, ebpf XDP_DROP, XDP_REDIRECT, XDP_PASS, XDP_TX.
It was verified with following configs enabled:
CONFIG_JIT=y
CONFIG_BPFILTER=y
CONFIG_BPF_SYSCALL=y
CONFIG_XDP_SOCKETS=y
CONFIG_BPF_EVENTS=y
CONFIG_HAVE_EBPF_JIT=y
CONFIG_BPF_JIT=y
CONFIG_CGROUP_BPF=y
Link on previous v1:
https://lkml.org/lkml/2019/5/23/795
Also regular tests with iperf2 were done in order to verify impact on
regular netstack performance, compared with base commit:

v1..v2:
- combined xdp_xmit functions
- used page allocation w/o refcnt juggle
- unmapped page for skb netstack
- moved rxq/page pool allocation to open/close pair
- added several preliminary patches:
net: page_pool: add helper function to retrieve dma addresses
net: page_pool: add helper function to unmap dma addresses
net: ethernet: ti: cpsw: use cpsw as drv data
net: ethernet: ti: cpsw_ethtool: simplify slave loops
Based on net-next/master
Ilias Apalodimas (2):
net: page_pool: add helper function to retrieve dma addresses
net: page_pool: add helper function to unmap dma addresses
Ivan Khoronzhuk (5):
net: ethernet: ti: cpsw: use cpsw as drv data
net: ethernet: ti: cpsw_ethtool: simplify slave loops
net: ethernet: ti: davinci_cpdma: add dma mapped submit
net: ethernet: ti: davinci_cpdma: return handler status
net: ethernet: ti: cpsw: add XDP support
