Greetings:
Welcome to v7. Added CONFIG_XDP_SOCKETS to the selftests/driver/net
kernel config in patch 3. Updated the xdp_helper.c to return -1 on
AF_XDP non-existence, and updated queues.py to skip the test if AF_XDP
does not exist (but fail in other failure cases). Tested on kernels with
and without CONFIG_XDP_SOCKETS enabled.
This is an attempt to followup on something Jakub asked me about [1],
adding an xsk attribute to queues and more clearly documenting which
queues are linked to NAPIs...
After the RFC [2], Jakub suggested creating an empty nest for queues
which have a pool, so I've adjusted this version to work that way.
The nest can be extended in the future to express attributes about XSK
as needed. Queues which are not used for AF_XDP do not have the xsk
attribute present.
I've run the included test on:
- my mlx5 machine (via NETIF=)
- without setting NETIF
And the test seems to pass in both cases.
Thanks,
Joe

v7:
- Added CONFIG_XDP_SOCKETS to selftests/driver/net/config as suggested
by Stanislav.
- Updated xdp_helper.c to return -1 for AF_XDP non-existence, but 1
for other failures.
- Updated queues.py to mark test as skipped if AF_XDP does not exist.
v6: https://lore.kernel.org/bpf/20250210193903.16235-1-jdamato@fastly.com/
- Added ifdefs for CONFIG_XDP_SOCKETS in patch 2 as Stanislav
suggested.
v5: https://lore.kernel.org/bpf/20250208041248.111118-1-jdamato@fastly.com/
- Removed unused ret variable from patch 2 as Simon suggested.
v4: https://lore.kernel.org/lkml/20250207030916.32751-1-jdamato@fastly.com/
- Add patch 1, as suggested by Jakub, which adds an empty nest helper.
- Use the helper in patch 2, which makes the code cleaner and prevents
a possible bug.
v3: https://lore.kernel.org/netdev/20250204191108.161046-1-jdamato@fastly.com/
- Change comment format in patch 2 to avoid kdoc warnings. No other
changes.
v2: https://lore.kernel.org/all/20250203185828.19334-1-jdamato@fastly.com/
- Switched from RFC to actual submission now that net-next is open
- Adjusted patch 1 to include an empty nest as suggested by Jakub
- Adjusted patch 2 to update the test based on changes to patch 1, and
to incorporate some Python feedback from Jakub :)

Welcome to v6. Added ifdefs to patch 2 and built with CONFIG_XDP_SOCKETS

Add basic support to run various MIPS variants via kunit_tool using the
virtualized malta platform.
Various kunit tests from drivers/firmware/cirrus/ are failing on MIPS.
They are fixed in [0].

Use POSIX-conformant expression operator symbol '='.
The use of the non POSIX-conformant symbol '==' would work
in bash, but not in sh where the unexpected operator error
would result in test_smoke.sh being skipped.
Instead of changing the shebang to use bash, which may not be
available on all systems, use the POSIX-conformant expression
symbol '=' to test for equality.
Without this patch:
===================
# make -j8 TARGETS=tpm2 kselftest
# selftests: tpm2: test_smoke.sh
# ./test_smoke.sh: 9: [: 2: unexpected operator
ok 1 selftests: tpm2: test_smoke.sh # SKIP
With this patch:
================
# make -j8 TARGETS=tpm2 kselftest
# selftests: tpm2: test_smoke.sh
# Ran 9 tests in 9.236s
ok 1 selftests: tpm2: test_smoke.sh
