This new API aligns with\n the kernel PTP which already supports frequency adjustment. It brings DPDK\n closer in alignment with the kernel's best practice.\n\n(2)Refine the ptpclient application by applying a PI algorithm that leverages\n the new API to further improve timesync accuracy. These changes doesn't break\n original solution and creates a more accurate solution for DPDK-based high\n accuracy PTP. We have provided significant improvements for timesync accuracy\n on e810 and we believe these improvements will also benefit other devices.\n\nThe original command for starting ptpclient is:\n./build/examples/dpdk-ptpclient -a 0000:81:00.0 -c 1 -n 3 -- -T 0 -p 0x1\n\nThe command with PI algorithm is:\n./build/examples/dpdk-ptpclient -a 0000:81:00.0 -c 1 -n 3 -- -T 0 -p 0x1 -- controller=pi\n\n[RFC v2 1/3] ethdev: add frequency adjustment API.\n[RFC v2 2/3] examples/ptpclient: refine application.\n[RFC v2 3/3] examples/ptpclient: add frequency adjustment support.\n\nv2:\n* Remove the ice PMD part from the RFC.\n* Add description in cover letter.\n* Refine commit log in patch.\n\nSimei Su (3):\n ethdev: add frequency adjustment API\n examples/ptpclient: refine application\n examples/ptpclient: add frequency adjustment support\n\n examples/ptpclient/ptpclient.c | 222 +++++++++++++++++++++++++++++++++------\n lib/ethdev/ethdev_driver.h | 5 +\n lib/ethdev/ethdev_trace.h | 9 ++\n lib/ethdev/ethdev_trace_points.c | 3 +\n lib/ethdev/rte_ethdev.c | 18 ++++\n lib/ethdev/rte_ethdev.h | 19 ++++\n 6 files changed, 245 insertions(+), 31 deletions(-)" }
