Subject: [PATCH v3 net-next 0/5] xdp: introduce bulking for page_pool tx return path
Date: Wed, 4 Nov 2020 11:22:53 +0100 [thread overview]
Message-ID: <cover.1604484917.git.lorenzo@kernel.org> (raw)
XDP bulk APIs introduce a defer/flush mechanism to return
pages belonging to the same xdp_mem_allocator object
(identified via the mem.id field) in bulk to optimize
I-cache and D-cache since xdp_return_frame is usually run
inside the driver NAPI tx completion loop.
Convert mvneta, mvpp2 and mlx5 drivers to xdp_return_frame_bulk APIs.
Changes since v2:
- move mvneta changes in a dedicated patch
Changes since v1:
- improve comments
- rework xdp_return_frame_bulk routine logic
- move count and xa fields at the beginning of xdp_frame_bulk struct
- invert logic in page_pool_put_page_bulk for loop
