Subject: [PATCH net-next v12 05/10] netdev: add io_uring memory provider info
Date: Fri, 17 Jan 2025 16:11:43 +0000 [thread overview]
Message-ID: <45e621e569a0ad2c172a19d0bbe5977ff6ec42f3.1737129699.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
From: David Wei <[email protected]>
Add a nested attribute for io_uring memory provider info. For now it is
empty and its presence indicates that a particular page pool or queue
has an io_uring memory provider attached.
$ ./cli.py --spec netlink/specs/netdev.yaml --dump page-pool-get
[{'id': 80,
'ifindex': 2,
'inflight': 64,
'inflight-mem': 262144,
'napi-id': 525},
{'id': 79,
'ifindex': 2,
'inflight': 320,
'inflight-mem': 1310720,
'io_uring': {},
'napi-id': 525},
...
$ ./cli.py --spec netlink/specs/netdev.yaml --dump queue-get
[{'id': 0, 'ifindex': 1, 'type': 'rx'},
{'id': 0, 'ifindex': 1, 'type': 'tx'},
{'id': 0, 'ifindex': 2, 'napi-id': 513, 'type': 'rx'},
{'id': 1, 'ifindex': 2, 'napi-id': 514, 'type': 'rx'},
...
{'id': 12, 'ifindex': 2, 'io_uring': {}, 'napi-id': 525, 'type': 'rx'},
...
