Set 'softtabstop' to 4 spaces, which will hopefully help keep the indentation in this file consistent going forwards. This mirrors the modeline in scripts such as recordmcount.pl, ktest.pl, and others. Emacs seems to use 4 spaces to indent by default, so it doesn't require anything special here.

This file is using an ungodly mixture of 4 spaces, 2-wide tabs, 4-wide tabs, _and_ 8-wide tabs, making it really hard to find good editor settings for working with this file. Bite the bullet and reindent it by hand. I tried using both perltidy and vim, but neither of them were up to the task without changing too much or getting confused about what they were supposed to be doing. I did change a few instances of } else into } else (and same for elsif); the file is again written using both styles, and I left functions which already seemed self-consistent alone. You can verify that this commit only changes whitespace using e.g.: git diff --ignore-all-space --word-diff or to see (only) the instances where newlines were added/removed: git diff --ignore-all-space You can also see the delta from what perltidy would have wanted to do to this file (when asked to only indent it), which isn't that much in the end: perltidy -io -fnl scripts/kernel-doc git diff --no-index scripts/kernel-doc{,.tdy} Signed-off-by: Vegard Nossum <vegard.nossum@oracle.com> Acked-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net> Link: https://lore.kernel.org/r/20240208161705.888385-1-vegard.nossum@oracle.com

The Python module pyyaml is required to build the docs, but it is only listed in Documentation/sphinx/requirements.txt and is therefore missing when Sphinx is installed as a package and not via pip/pypi.

The number of possible CPUs is set be kernel in early boot time through some discovery mechanisms, like ACPI in x86. We have a parameter both in x86 and S390 to override that - there are some cases of BIOSes exposing more possible CPUs than the available ones, so this parameter is a good testing mechanism, but for some reason wasn't mentioned so far in the kernel parameters guide - let's fix that.

The kernel subsystem APIs front page currently has four top-level groupings with headers, and then everything else that isn't grouped. But in the table-of-contents, ungrouped subsystems are indented as if they were part of the preceding grouping (currently "Storage interfaces"), which is confusing.

Leo Yan authored
In the Linux perf tool, the ring buffer serves not only as a medium for transferring PMU event data but also as a vital mechanism for hardware tracing using technologies like Intel PT and Arm CoreSight, etc. Consequently, the ring buffer mechanism plays a crucial role by ensuring high throughput for data transfer between the kernel and user space while avoiding excessive overhead caused by the ring buffer itself. This commit documents the ring buffer mechanism in detail. It explains the implementation of both the regular ring buffer and the AUX ring buffer. Additionally, it covers how these ring buffers support various tracing modes and explains the synchronization with memory barriers.

It's good to be clear about who the intended target audience for any given piece of documentation is, as this will help us put new text in the correct place. Let's encourage submitters to state it explicitly rather than relying on where they placed it in the directory hierarchy as there isn't necessarily a one-to-one correspondence between them.
