79917b242c3fe0d89e4752bc25ffef4574c2194b - Merge branch 'af_xdp-common-alloc'

Fri, 22 May 2020 02:31:27 +0200

Merge branch 'af_xdp-common-alloc'Björn Töpel says:====================Overview========Driver adoption for AF_XDP has been slow. The amount of code requiredto proper support AF_XDP is substantial and the driver/core APIs arevague or even non-existing. Drivers have to manually adjust dataoffsets, updating AF_XDP handles differently for different modes(aligned/unaligned).This series attempts to improve the situation by introducing an AF_XDPbuffer allocation API. The implementation is based on a single core(single producer/consumer) buffer pool for the AF_XDP UMEM.A buffer is allocated using the xsk_buff_alloc() function, andreturned using xsk_buff_free(). If a buffer is disassociated with thepool, e.g. when a buffer is passed to an AF_XDP socket, a buffer issaid to be released. Currently, the release function is only used bythe AF_XDP internals and not visible to the driver.Drivers using this API should register the XDP memory model with thenew MEM_TYPE_XSK_BUFF_POOL type, which will supersede theMEM_TYPE_ZERO_COPY type.The buffer type is struct xdp_buff, and follows the lifetime ofregular xdp_buffs, i.e. the lifetime of an xdp_buff is restricted toa NAPI context. In other words, the API is not replacing xdp_frames.DMA mapping/synching is folded into the buffer handling as well.@JeffK The Intel drivers changes should go through the bpf-next tree, and not your regular Intel tree, since multiple (non-Intel) drivers are affected.The outline of the series is as following:Patch 1 is a fix for xsk_umem_xdp_frame_sz().Patch 2 to 4 are restructures/clean ups. The XSKMAP implementation ismoved to net/xdp/. Functions/defines/enums that are only used by theAF_XDP internals are moved from the global include/net/xdp_sock.h tonet/xdp/xsk.h. We are also introducing a new "driver include file",include/net/xdp_sock_drv.h, which is the only file NIC driverdevelopers adding AF_XDP zero-copy support should care about.Patch 5 adds the new API, and migrates the "copy-mode"/skb-mode AF_XDPpath to the new API.Patch 6 to 11 migrates the existing zero-copy drivers to the new API.Patch 12 removes the MEM_TYPE_ZERO_COPY memory type, and the "handle"member of struct xdp_buff.Patch 13 simplifies the xdp_return_{frame,frame_rx_napi,buff}functions.Patch 14 is a performance patch, where some functions are inlined.Finally, patch 15 updates the MAINTAINERS file to correctly mirror thenew file layout.Note that this series removes the "handle" member from structxdp_buff, which reduces the xdp_buff size.After this series, the diff stat of drivers/net/ is: 27 files changed, 419 insertions(+), 1288 deletions(-)This series is a first step of simplifying the driver side ofAF_XDP. I think more of the AF_XDP logic can be moved from the driversto the AF_XDP core, e.g. the "need wakeup" set/clear functionality.Statistics when allocation fails can now be added to the socketstatistics via the XDP_STATISTICS getsockopt(). This will be added ina follow up series.Performance===========As a nice side effect, performance is up a bit as well. * i40e: 3% higher pps for rxdrop, zero-copy, aligned and unaligned (40 GbE, 64B packets). * mlx5: RX +0.8 Mpps, TX +0.4 MppsChangelog=========v4->v5: * Fix various kdoc and GCC warnings (W=1).

(Björn) * Make sure xp_validate_desc() is inlined for Tx perf. (Maxim) * Sorted file entries.
