2026-01-27tracing: Add show_event_triggers to expose active event triggersAaron Tomlin1-0/+8
To audit active event triggers, userspace currently must traverse the events/ directory and read each individual trigger file. This is cumbersome for system-wide auditing or debugging. Introduce "show_event_triggers" at the trace root directory. This file displays all events that currently have one or more triggers applied, alongside the trigger configuration, in a consolidated system:event [tab] trigger format. The implementation leverages the existing trace_event_file iterators and uses the trigger's own print() operation to ensure output consistency with the per-event trigger files.

2026-01-27tracing: Add show_event_filters to expose active event filtersAaron Tomlin1-0/+8
Currently, to audit active Ftrace event filters, userspace must recursively traverse the events/ directory and read each individual filter file. This is inefficient for monitoring tools and debugging. Introduce "show_event_filters" at the trace root directory. This file displays all events that currently have a filter applied, alongside the actual filter string, in a consolidated system:event [tab] filter format. The implementation reuses the existing trace_event_file iterators to ensure atomic traversal of the event list and utilises guard(rcu)() for automatic, scope-based protection when accessing volatile filter strings.

2026-01-27tracing: Add bitmask-list option for human-readable bitmask displayAaron Tomlin1-0/+9
Add support for displaying bitmasks in human-readable list format (e.g., 0,2-5,7) in addition to the default hexadecimal bitmap representation. This is particularly useful when tracing CPU masks and other large bitmasks where individual bit positions are more meaningful than their hexadecimal encoding. When the "bitmask-list" option is enabled, the printk "%*pbl" format specifier is used to render bitmasks as comma-separated ranges, making trace output easier to interpret for complex CPU configurations and large bitmask values.

Logical power domain is used to abstract these resources in firmware and SCMI power protocol is used to request resource operations by using runtime PM framework APIs such as pm_runtime_get/put_sync to invoke power_on/_off calls from kernel respectively.

Document the device tree bindings for UFS host controller on Qualcomm SA8255P platform which integrates firmware-managed resources. The platform firmware implements the SCMI server and manages resources such as the PHY, clocks, regulators and resets via the SCMI power protocol. As a result, the OS-visible DT only describes the controller’s MMIO, interrupt, IOMMU and power-domain interfaces. The generic "qcom,ufshc" and "jedec,ufs-2.0" compatible strings are removed from the binding, since this firmware managed design won't be compatible with the drivers doing full resource management.

In clang version 21.1 and later the -Wimplicit-enum-enum-cast warning option has been introduced. This warning is enabled by default and can be used to catch .queuecommand() implementations that return another value than 0 or one of the SCSI_MLQUEUE_* constants. Hence this patch that changes the return type of the .queuecommand() implementations from 'int' into 'enum scsi_qc_status'. No functionality has been changed.

2026-01-23Documentation: use a source-read extension for the index link boilerplateJani Nikula101-685/+31
The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.

2026-01-23Merge branch 'mauro' into docs-mwJonathan Corbet15-10/+214
Mauro's work to include documentation from our Python modules. His cover letter follows: This is an extended version of: https://lore.kernel.org/linux-doc/cover.1768488832.git.mchehab+huawei@kernel.org/ It basically adds everything we currently have inside libs/tool/python to "tools" book inside documentation. This version should be independent of the other series yet to be merged, (including the jobserver one). The vast amount of changes here are docstring cleanups and additions. They mainly consists on: - ensuring that every phrase will end with a period, making it uniform along all files; - cleaning ups to better uniform docstrings; - variable descriptions now use "#:" markup, as it allows autodoc to add them inside the documentation; - added some missing docstrings; - some new blank lines at comments to make ReST syntax parser happy; - add a couple of sphinx markups (mainly, code blocks). Most of those are minor changes, affecting only comments. It also has one patch per libarary type, adding them to docs. For kernel-doc, I did the cleanups first, as there is one code block inside tools/lib/python/kdoc/latex_fonts.py that would cause a Sphinx crash without such markups. The series actually starts with 3 fixes: - avoid "*" markups on indexes with deep> 3 to override text - a variable rename to stop abusing doctree name - don't rely on cwd to get Documentation/ location patch 4 adds support to document scripts either at: - tools/ - scripts/ patch 5 contains a CSS to better display autodoc html output. For those who want to play with documentation, documenting a python file is very simple. All it takes is to use: .. automodule:: lib.python.<dir+name> Usually, we add a couple of control members to it to adjust the desired documentation scope (add/remove members, showing class inheritance, showing members that currently don't have docstrings, etc). That's why we're using: .. automodule:: lib.python.kdoc.enrich_formatter :members: :show-inheritance: :undoc-members: (and similar) inside tools/kdoc*.rst. autodoc allows filtering in/out members, file docstrings, etc. It also allows documenting just some members or functions with directives like: ..autofunction: ..automember: Sphinx also has a helper script to generate .rst files with documentation: $ sphinx-apidoc -o foobar tools/lib/python/ which can be helpful to discover what should be documented, although changes are needed to use what it produces.
