2025-07-24tools: ynl-gen: print setters for multi-val attrsJakub Kicinski
For basic types we "flatten" setters. If a request "a" has a simple nest "b" with value "val" we print helpers like: req_set_a_b(struct a *req, int val) { req->_present.a = 1; req->b._present.val = 1; req->b.val = ... } This is not possible for multi-attr because they have to be allocated dynamically by the user. Print "object level" setters so that user preparing the object doesn't have to futz with the presence bits and other YNL internals. Add the ability to pass in the variable name to generated setters. Using "req" here doesn't feel right, while the attr is part of a request it's not the request itself, so it seems cleaner to call it "obj". Example: static inline void netdev_queue_id_set_id(struct netdev_queue_id *obj, __u32 id) { obj->_present.id = 1; obj->id = id; } Reviewed-by: Donald Hunter <donald.hunter@gmail.com> Acked-by: Stanislav Fomichev <sdf@fomichev.me> Link: https://patch.msgid.link/20250723171046.4027470-5-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-07-24tools: ynl-gen: print alloc helper for multi-val attrsJakub Kicinski
In general YNL provides allocation and free helpers for types. For pure nested structs which are used as multi-attr (and therefore have to be allocated dynamically) we already print a free helper as it's needed by free of the containing struct. Add printing of the alloc helper for consistency. The helper takes the number of entries to allocate as an argument, e.g.: static inline struct netdev_queue_id *netdev_queue_id_alloc(unsigned int n) { return calloc(n, sizeof(struct netdev_queue_id)); } Reviewed-by: Donald Hunter <donald.hunter@gmail.com> Acked-by: Stanislav Fomichev <sdf@fomichev.me> Link: https://patch.msgid.link/20250723171046.4027470-4-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2025-07-24x86: Handle KCOV __init vs inline mismatchesKees Cook
GCC appears to have kind of fragile inlining heuristics, in the sense that it can change whether or not it inlines something based on optimizations. It looks like the kcov instrumentation being added (or in this case, removed) from a function changes the optimization results, and some functions marked "inline" are _not_ inlined. In that case, we end up with __init code calling a function not marked __init, and we get the build warnings I'm trying to eliminate in the coming patch that adds __no_sanitize_coverage to __init functions: WARNING: modpost: vmlinux: section mismatch in reference: xbc_exit+0x8 (section: .text.unlikely) -> _xbc_exit (section: .init.text) WARNING: modpost: vmlinux: section mismatch in reference: real_mode_size_needed+0x15 (section: .text.unlikely) -> real_mode_blob_end (section: .init.data) WARNING: modpost: vmlinux: section mismatch in reference: __set_percpu_decrypted+0x16 (section: .text.unlikely) -> early_set_memory_decrypted (section: .init.text) WARNING: modpost: vmlinux: section mismatch in reference: memblock_alloc_from+0x26 (section: .text.unlikely) -> memblock_alloc_try_nid (section: .init.text) WARNING: modpost: vmlinux: section mismatch in reference: acpi_arch_set_root_pointer+0xc (section: .text.unlikely) -> x86_init (section: .init.data) WARNING: modpost: vmlinux: section mismatch in reference: acpi_arch_get_root_pointer+0x8 (section: .text.unlikely) -> x86_init (section: .init.data) WARNING: modpost: vmlinux: section mismatch in reference: efi_config_table_is_usable+0x16 (section: .text.unlikely) -> xen_efi_config_table_is_usable (section: .init.text) This problem is somewhat fragile (though using either __always_inline or __init will deterministically solve it), but we've tripped over this before with GCC and the solution has usually been to just use __always_inline and move on.

2025-07-24selftests/pidfd: Fix duplicate-symbol warnings for SCHED_ CPP symbolsPaul E. McKenney
The pidfd selftests run in userspace and include both userspace and kernel header files. On some distros (for example, CentOS), this results in duplicate-symbol warnings in allmodconfig builds, while on other distros (for example, Ubuntu) it does not. Therefore, use #undef to get rid of the userspace definitions in favor of the kernel definitions. Other ways of handling this include splitting up the selftest code so that the userspace definitions go into one translation unit and the kernel definitions into another (which might or might not be feasible) or to adjust compiler command-line options to suppress the warnings (which might or might not be desirable).

git://git.kernel.org/pub/scm/linux/kernel/git/fustini/linux into clk-thead Pull one more T-HEAD clk driver update from Drew Fustini: Yao Zi has fixed an issue where the c910 mux clk could end up as an orphan in CCF when the bootloader reparents it to the c910-i0 mux clk. The solution is to refactor the handling of mux clocks by embedding a clk_mux structure directly in ccu_mux. This allows the mux clocks to be registered with devm_clk_hw_register() without allocating any new clk_hw pointer which solves the orphan issue. This change has been tested in linux-next. The LPi4a still boots okay without clk_ignore_unused and peripherals like serial, emmc and ethernet are functional.

2025-07-24selftests/tracing: Fix false failure of subsystem event testSteven Rostedt
The subsystem event test enables all "sched" events and makes sure there's at least 3 different events in the output. It used to cat the entire trace file to | wc -l, but on slow machines, that could last a very long time. To solve that, it was changed to just read the first 100 lines of the trace file. This can cause false failures as some events repeat so often, that the 100 lines that are examined could possibly be of only one event. Instead, create an awk script that looks for 3 different events and will exit out after it finds them. This will find the 3 events the test looks for (eventually if it works), and still exit out after the test is satisfied and not cause slower machines to run forever.

2025-07-24PCI: endpoint: pci-epf-test: Add doorbell test supportFrank Li
Add doorbell support by allocating a dedicated BAR using the pci_epf_alloc_doorbell() API and mapping the Endpoint MSI controller message data address to it. The data to be written in the message address is stored in the 'pci_epf_test_reg::doorbell_data' register. Finally, the RC can trigger doorbell in the Endpoint by writing the content of 'doorbell_data' register to the offset specified in 'doorbell_offset' of the 'doorbell_bar' BAR. Triggering of the doorbell is detected by pci_epf_test_doorbell_handler(), which is bound to the doorbell IRQ. On successful completion, STATUS_DOORBELL_SUCCESS status is set in the above mentioned handler. To avoid breaking compatibility between host and endpoint, add two new commands: COMMAND_ENABLE_DOORBELL and COMMAND_DISABLE_DOORBELL. The doorbell is allocated when COMMAND_ENABLE_DOORBELL command is called and destroyed when COMMAND_DISABLE_DOORBELL is called. This doorbell feature only works when both RC and EP drivers support it. If one of them doesn't support the feature, the testcase will fail.

2025-07-24PCI: endpoint: pci-ep-msi: Add checks for MSI parent and mutabilityFrank Li
Some MSI controllers can change address/data pair during the execution of irq_chip::irq_set_affinity() callback. Since the current PCI Endpoint framework cannot support mutable MSI controllers, call irq_domain_is_msi_immutable() API to check if the controller is immutable or not. Also ensure that the MSI domain is a parent MSI domain so that it can allocate address/data pairs.

2025-07-24PCI: endpoint: Add RC-to-EP doorbell support using platform MSI controllerFrank Li
Implement the doorbell feature by mapping the EP's MSI interrupt controller message address to a dedicated BAR. The EPF driver should pass the actual message data to be written to the message address by the host through implementation-specific logic.
