      xdp: For Intel AF_XDP drivers add XDP frame_sz · 2a637c5b
      Jesper Dangaard Brouer 提交于
      Intel drivers implement native AF_XDP zerocopy in separate C-files,
      that have its own invocation of bpf_prog_run_xdp(). The setup of
      xdp_buff is also handled in separately from normal code path.
      
      This patch update XDP frame_sz for AF_XDP zerocopy drivers i40e, ice
      and ixgbe, as the code changes needed are very similar.  Introduce a
      helper function xsk_umem_xdp_frame_sz() for calculating frame size.

      i40e: Add XDP frame size to driver · 24104024
      Jesper Dangaard Brouer 提交于
      This driver uses different memory models depending on PAGE_SIZE at
      compile time. For PAGE_SIZE 4K it uses page splitting, meaning for
      normal MTU frame size is 2048 bytes (and headroom 192 bytes). For
      larger MTUs the driver still use page splitting, by allocating
      order-1 pages (8192 bytes) for RX frames. For PAGE_SIZE larger than
      4K, driver instead advance its rx_buffer->page_offset with the frame
      size "truesize".
      
      For XDP frame size calculations, this mean that in PAGE_SIZE larger
      than 4K mode the frame_sz change on a per packet basis. For the page
      split 4K PAGE_SIZE mode, xdp.frame_sz is more constant and can be
      updated once outside the main NAPI loop.
      
      The default setting in the driver uses build_skb(), which provides
      the necessary headroom and tailroom for XDP-redirect in RX-frame
      (in both modes).
      
      There is one complication, which is legacy-rx mode (configurable via
      ethtool priv-flags). There are zero headroom in this mode, which is a
      requirement for XDP-redirect to work. The conversion to xdp_frame
      (convert_to_xdp_frame) will detect this insufficient space, and
      xdp_do_redirect() call will fail. This is deemed acceptable, as it
      allows other XDP actions to still work in legacy-mode. In
      legacy-mode + larger PAGE_SIZE due to lacking tailroom, we also
      accept that xdp_adjust_tail shrink doesn't work.

      netdev: pass the stuck queue to the timeout handler · 0290bd29
      Michael S. Tsirkin 提交于
      This allows incrementing the correct timeout statistic without any mess.
      Down the road, devices can learn to reset just the specific queue.

      i40e: need_wakeup flag might not be set for Tx · 70563957
      Magnus Karlsson 提交于
      The need_wakeup flag for Tx might not be set for AF_XDP sockets that
      are only used to send packets. This happens if there is at least one
      outstanding packet that has not been completed by the hardware and we
      get that corresponding completion (which will not generate an
      interrupt since interrupts are disabled in the napi poll loop) between
      the time we stopped processing the Tx completions and interrupts are
      enabled again. In this case, the need_wakeup flag will have been
      cleared at the end of the Tx completion processing as we believe we
      will get an interrupt from the outstanding completion at a later point
      in time. But if this completion interrupt occurs before interrupts
      are enable, we lose it and should at that point really have set the
      need_wakeup flag since there are no more outstanding completions that
      can generate an interrupt to continue the processing. When this
      happens, user space will see a Tx queue need_wakeup of 0 and skip
      issuing a syscall, which means will never get into the Tx processing
      again and we have a deadlock.
      
      This patch introduces a quick fix for this issue by just setting the
      need_wakeup flag for Tx to 1 all the time. I am working on a proper
      fix for this that will toggle the flag appropriately, but it is more
      challenging than I anticipated and I am afraid that this patch will
      not be completed before the merge window closes, therefore this easier
      fix for now. This fix has a negative performance impact in the range
      of 0% to 4%. Towards the higher end of the scale if you have driver
      and application on the same core and issue a lot of packets, and
      towards no negative impact if you use two cores, lower transmission
      speeds and/or a workload that also receives packets.

      igb/igc: use ktime accessors for skb->tstamp · 6acab13b
      Jacob Keller 提交于
      When implementing launch time support in the igb and igc drivers, the
      skb->tstamp value is assumed to be a s64, but it's declared as a ktime_t
      value.
      
      Although ktime_t is typedef'd to s64 it wasn't always, and the kernel
      provides accessors for ktime_t values.
      
      Use the ktime_to_timespec64 and ktime_set accessors instead of directly
      assuming that the variable is always an s64.
      
      This improves portability if the code is ever moved to another kernel
      version, or if the definition of ktime_t ever changes again in the
      future.
