XDP for idpf is currently 5.(6) chapters: * convert Rx to libeth; * convert Tx and stats to libeth; * generic XDP and XSk code changes; * generic XDP and XSk code additions pt. 1; * generic XDP and XSk code additions pt. 2 (you are here); * actual XDP for idpf via new libeth_xdp; * XSk for idpf (via ^). Part III.3 does the following: * adds generic functions to build skbs from xdp_buffs (regular and XSk) and attach frags to xdp_buffs (regular and XSk); * adds helper to optimize XSk xmit in drivers; * add generic loop unroll hint macros. Everything is prereq for libeth_xdp, but will be useful standalone as well: less code in drivers, faster XSk XDP_PASS, smaller object code. Alexander Lobakin (7): page_pool: add page_pool_dev_alloc_netmem() xdp: add generic xdp_buff_add_frag() xdp: add generic xdp_build_skb_from_buff() xsk: make xsk_buff_add_frag() really add the frag via __xdp_buff_add_frag() xsk: add generic XSk &xdp_buff -> skb conversion xsk: add helper to get &xdp_desc's DMA and meta pointer in one go unroll: add generic loop unroll helpers include/linux/skbuff.h | 16 +- include/linux/unroll.h | 44 +++++ include/net/page_pool/helpers.h | 9 ++ include/net/xdp.h | 98 +++++++++++- include/net/xdp_sock_drv.h | 41 ++++- include/net/xsk_buff_pool.h | 8 + drivers/net/ethernet/intel/i40e/i40e_xsk.c | 30 +--- drivers/net/ethernet/intel/ice/ice_xsk.c | 32 +--- net/core/xdp.c | 178 +++++++++++++++++++++ net/xdp/xsk_buff_pool.c | 40 +++++ 10 files changed, 431 insertions(+), 65 deletions(-) --- Each patch except trivial 0001 was on the lists already. Since the not applied part of Chapter III.2: * rebase on top of Mina's netmem fixes; * 0003: remove redundant double CONFIG_PAGE_POOL check (one inside and another one outside of skb_mark_for_recycle()) (Jakub); * 0005: remove !CONFIG_PAGE_POOL code as unreachable (eBPF always selects it) (also Jakub); * 0005: actually check the pfmemalloc flag of newly allocated frags; * drop exporting static_key_{inc,dec}_cpuslocked() -- were used on slowpath in very unlikely case where saving a few cycles looked worse and less convienient than the "regular" way.
