Subject: [PATCH net-next v2 0/4] Change BPF_TEST_RUN use the system page pool for live XDP frames
Date: Tue, 20 Feb 2024 22:03:37 +0100 [thread overview]
Message-ID: <20240220210342.40267-1-toke@redhat.com> (raw)
Now that we have a system-wide page pool, we can use that for the live
frame mode of BPF_TEST_RUN (used by the XDP traffic generator), and
avoid the cost of creating a separate page pool instance for each
syscall invocation. See the individual patches for more details.
This series targets net-next because it depends on this series of
Lorenzo's, that adds a global system page pool:

Changelog:
v2:
- Change the cookie that marks the page for recycling to be a 128-bit
value (Paolo)
- Add a patch that removes the init_callback parameter from page
pool (Olek)
- Carry forward review tags from v1
Toke Høiland-Jørgensen (4):
net: Register system page pool as an XDP memory model
bpf: test_run: Use system page pool for XDP live frame mode
bpf: test_run: Fix cacheline alignment of live XDP frame data
structures
page pool: Remove init_callback parameter
