[PATCH 0/6] KUnit test moves / renames

by David Gow

As discussed in [1], the KUnit test naming scheme has changed to avoid name conflicts (and tab-completion woes) with the files being tested. These renames and moves have caused a nasty set of merge conflicts, so this series collates and rebases them all to be applied via mm-nonmm-unstable alongside any lib/ changes[2]. Thanks to everyone whose patches appear here, and everyone who reviewed on the original series. I hope I didn't break them too much during the rebase!

But actually it is common method. This patches add new API to pci-epf-core, so any EP driver can use it. Previous v2 discussion here. https://lore.kernel.org/imx/20230911220920.1817033-1-Frank.Li@nxp.com/ Changes in v14: Marc Zyngier raised concerns about adding DOMAIN_BUS_DEVICE_PCI_EP_MSI. As a result, the approach has been reverted to the v9 method. However, there are several improvements: MSI now supports msi-map in addition to msi-parent. - The struct device: id is used as the endpoint function (EPF) device identity to map to the stream ID (sideband information). - The EPC device tree source (DTS) utilizes msi-map to provide such information. - The EPF device's of_node is set to the EPC controller’s node. This approach is commonly used for multi-function device (MFD) platform child devices, allowing them to inherit properties from the MFD device’s DTS, such as reset-cells and gpio-cells. This method is well-suited for the current case, as the EPF is inherently created/binded to the EPC and should inherit the EPC’s DTS node properties. Additionally: Since the basic IMX95 LUT support has already been merged into the mainline, a DTS and driver increment patch is added to complete the solution. The patch is rebased onto the latest linux-next tree and aligned with the new pcitest framework. - Link to v13: https://lore.kernel.org/r/20241218-ep-msi-v13-0-646e2192dc24@nxp.com Changes in v13: - Change to use DOMAIN_BUS_PCI_DEVICE_EP_MSI - Change request id as func | vfunc << 3 - Remove IRQ_DOMAIN_MSI_IMMUTABLE Thomas Gleixner: I hope capture all your points in review comments. If missed, let me know. - Link to v12: https://lore.kernel.org/r/20241211-ep-msi-v12-0-33d4532fa520@nxp.com Changes in v12: - Change to use IRQ_DOMAIN_MSI_IMMUTABLE and add help function irq_domain_msi_is_immuatble(). - split PCI: endpoint: pci-ep-msi: Add MSI address/data pair mutable check to 3 patches - Link to v11: https://lore.kernel.org/r/20241209-ep-msi-v11-0-7434fa8397bd@nxp.com Changes in v11: - Change to use MSI_FLAG_MSG_IMMUTABLE - Link to v10: https://lore.kernel.org/r/20241204-ep-msi-v10-0-87c378dbcd6d@nxp.com Changes in v10: Thomas Gleixner: There are big change in pci-ep-msi.c. I am sure if go on the corrent path. The key improvement is remove only 1 function devices's limitation. I use new patch for imutable check, which relative additional feature compared to base enablement patch. - Remove patch Add msi_remove_device_irq_domain() in platform_device_msi_free_irqs_all() - Add new patch irqchip/gic-v3-its: Avoid overwriting msi_prepare callback if provided by msi_domain_info - Remove only support 1 endpoint function limiation. - Create one MSI domain for each endpoint function devices. - Use "msi-map" in pci ep controler node, instead of of msi-parent. first argument is (func_no << 8 | vfunc_no) - Link to v9: https://lore.kernel.org/r/20241203-ep-msi-v9-0-a60dbc3f15dd@nxp.com Changes in v9 - Add patch platform-msi: Add msi_remove_device_irq_domain() in platform_device_msi_free_irqs_all() - Remove patch PCI: endpoint: Add pci_epc_get_fn() API for customizable filtering - Remove API pci_epf_align_inbound_addr_lo_hi - Move doorbell_alloc in to doorbell_enable function. - Link to v8: https://lore.kernel.org/r/20241116-ep-msi-v8-0-6f1f68ffd1bb@nxp.com Changes in v8: - update helper function name to pci_epf_align_inbound_addr() - Link to v7: https://lore.kernel.org/r/20241114-ep-msi-v7-0-d4ac7aafbd2c@nxp.com Changes in v7: - Add helper function pci_epf_align_addr(); - Link to v6: https://lore.kernel.org/r/20241112-ep-msi-v6-0-45f9722e3c2a@nxp.com Changes in v6: - change doorbell_addr to doorbell_offset - use round_down() - add Niklas's test by tag - rebase to pci/endpoint - Link to v5: https://lore.kernel.org/r/20241108-ep-msi-v5-0-a14951c0d007@nxp.com Changes in v5: - Move request_irq to epf test function driver for more flexiable user case - Add fixed size bar handler - Some minor improvememtn to see each patches's changelog. - Link to v4: https://lore.kernel.org/r/20241031-ep-msi-v4-0-717da2d99b28@nxp.com Changes in v4: - Remove patch genirq/msi: Add cleanup guard define for msi_lock_descs()/msi_unlock_descs() - Use new method to avoid compatible problem. Add new command DOORBELL_ENABLE and DOORBELL_DISABLE. pcitest -B send DOORBELL_ENABLE first, EP test function driver try to remap one of BAR_N (except test register bar) to ITS MSI MMIO space.

[PATCH net-next v5 0/3] netdev-genl: Add an xsk attribute to queues

by Joe Damato

Greetings Welcome to v5. No functional changes; removed an unused variable from patch 2. 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 [1]: https://lore.kernel.org/netdev/20250113143109.60afa59a@kernel.org/ [2]: https://lore.kernel.org/netdev/20250129172431.65773-1-jdamato@fastly.com/ v5: - 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 :) rfc: https://lore.kernel.org/netdev/20250129172431.65773-1-jdamato@fastly.com/ Joe Damato (3): netlink: Add nla_put_empty_nest helper netdev-genl: Add an XSK attribute to queues selftests: drv-net: Test queue xsk attribute Documentation/netlink/specs/netdev.yaml | 13 ++- include/net/netlink.h | 15 ++++ include/uapi/linux/netdev.h | 6 ++ net/core/netdev-genl.c | 11 +++ tools/include/uapi/linux/netdev.h | 6 ++ .../testing/selftests/drivers/net/.gitignore | 2 + tools/testing/selftests/drivers/net/Makefile | 3 + tools/testing/selftests/drivers/net/queues.py | 35 +++++++- .../selftests/drivers/net/xdp_helper.c | 89 +++++++++++++++++++ 9 files changed, 177 insertions(+), 3 deletions(-) create mode 100644 tools/testing/selftests/drivers/net/.gitignore create mode 100644 tools/testing/selftests/drivers/net/xdp_helper.c base-commit: 233a2b1480a0bdf6b40d4debf58a07084e9921ff -- 2.43.0

[PATCH bpf-next] selftests/bpf: Remove with_addr.sh and with_tunnels.sh

by Bastien Curutchet (eBPF Foundation)

Those two scripts were used by test_flow_dissector.sh to setup/cleanup the network topology before/after the tests. test_flow_dissector.sh have been deleted by commit 63b37657c5fd ("selftests/bpf: remove test_flow_dissector.sh") so they aren't used anywhere now. Remove the two unused scripts and their Makefile entries.
