Subject: [PATCH bpf-next 0/5] Bulk optimization for XDP cpumap redirect
Date: Wed, 10 Apr 2019 13:43:32 +0200 [thread overview]
Message-ID: <155489659290.20826.1108770347511292618.stgit@firesoul> (raw)
This patchset utilize a number of different kernel bulk APIs for optimizing
the performance for the XDP cpumap redirect feature.
Patch-1: ptr_ring batch consume
Patch-2: Send SKB-lists to network stack
Patch-3: Introduce SKB helper to alloc SKB outside net-core
Patch-4: kmem_cache bulk alloc of SKBs
Patch-5: Prefetch struct page to solve CPU stall
---
Jesper Dangaard Brouer (5):
bpf: cpumap use ptr_ring_consume_batched
bpf: cpumap use netif_receive_skb_list
net: core: introduce build_skb_around
bpf: cpumap do bulk allocation of SKBs
bpf: cpumap memory prefetchw optimizations for struct page
