Subject: [PATCH v4 net-next 0/4] net: ethernet: ti: cpsw: Add XDP support
Date: Tue, 25 Jun 2019 20:59:44 +0300 [thread overview]
Message-ID: <20190625175948.24771-1-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 v3:

Also regular tests with iperf2 were done in order to verify impact on
regular netstack performance, compared with base commit:
https://pastebin.com/JSMT0iZ4
v3..v4:
- added page pool user counter
- use same pool for ndevs in dual mac
- restructured page pool create/destroy according to the last changes in API
v2..v3:
- each rxq and ndev has its own page pool
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
Ivan Khoronzhuk (4):
net: core: page_pool: add user cnt preventing pool deletion
net: ethernet: ti: davinci_cpdma: add dma mapped submit
net: ethernet: ti: davinci_cpdma: return handler status
net: ethernet: ti: cpsw: add XDP support
