Subject: [RFC PATCH v1 0/3] liburing: add api for napi busy poll timeout
Date: Thu, 3 Nov 2022 13:40:14 -0700 [thread overview]
Message-ID: <20221103204017.670757-1-shr@devkernel.io> (raw)
This adds two new api's to set and clear the napi busy poll timeout. The
two new functions are called:
- io_uring_register_busy_poll_timeout and
- io_uring_unregister_busy_poll_timeout.
The patch series also contains the documentation for the two new functions
and two test programs. The client program is called napi-busy-poll-client
and the server program napi-busy-poll-server. The client measures the
roundtrip times of requests.
There is also a kernel patch "io-uring: support napi busy poll" to enable
this feature on the kernel side.
