This series contains updates to i40e driver only. Li RongQing removes binding affinity mask to a fixed CPU and sets prefetch of Rx buffer page to occur conditionally.
Björn provides AF_XDP performance improvements by not prefetching HW descriptors, using 16 byte descriptors, and moving buffer allocation out of Rx processing loop. v2: Define prefetch_page_address in a common header for patch 2. Dropped, previous, patch 5 as it is being reworked to be more generalized. The following are changes since commit e059c6f340f6fccadd3db9993f06d4cc51305804: tulip: switch from 'pci_' to 'dma_' API and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 40GbE Björn Töpel (3): i40e, xsk: remove HW descriptor prefetch in AF_XDP path i40e: use 16B HW descriptors instead of 32B i40e, xsk: move buffer allocation out of the Rx processing loop Li RongQing (2): i40e: not compute affinity_mask for IRQ i40e: optimise prefetch page refcount drivers/net/ethernet/intel/i40e/i40e.h | 2 +- .../net/ethernet/intel/i40e/i40e_debugfs.c | 10 ++++---- drivers/net/ethernet/intel/i40e/i40e_main.c | 16 ++++--------- drivers/net/ethernet/intel/i40e/i40e_trace.h | 6 ++--- drivers/net/ethernet/intel/i40e/i40e_txrx.c | 21 ++++++++++++---- drivers/net/ethernet/intel/i40e/i40e_txrx.h | 2 +- .../ethernet/intel/i40e/i40e_txrx_common.h | 13 ---------- drivers/net/ethernet/intel/i40e/i40e_type.h | 5 +++- drivers/net/ethernet/intel/i40e/i40e_xsk.c | 24 ++++++++++++------- include/linux/prefetch.h | 8 +++++++ 10 files changed, 59 insertions(+), 48 deletions(-) -- 2.26.2
