2024-02-29kernel-doc: Add unary operator * to $type_param_refAkira Yokosawa1-1/+1
In kernel-doc comments, unary operator * collides with Sphinx/ docutil's markdown for emphasizing. This resulted in additional warnings from "make htmldocs": WARNING: Inline emphasis start-string without end-string. , as reported recently [1]. Those have been worked around either by escaping * (like \*param) or by using inline-literal form of ``*param``, both of which are specific to Sphinx/docutils. Such workarounds are against the kenrel-doc's ideal and should better be avoided. Instead, add "*" to the list of unary operators kernel-doc recognizes and make the form of *@param available in kernel-doc comments.

2024-02-21kernel-doc: handle #if in enums as wellJohannes Berg1-1/+1
In addition to #ifdef, #define and #endif, also handle any #if since we may be using e.g. #if IS_ENABLED(...). I didn't find any instances of this in the kernel now, there are enums with such ifs inside, but I didn't find any with kernel-doc as well. However, it came up as we were adding such a construct in our driver and warnings from kernel-doc were the result.

2024-02-15scripts/kernel-doc: reindentVegard Nossum1-1264/+1258
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 warning for Excess struct or union member description was removed when the $nested parameter of check_sections() was removed. This causes some kernel-doc notation warnings to be missed. Recently the kernel test robot somehow reported an Excess member. The code in kernel-doc has not issued that warning since kernel v4.16, so I don't know how the robot did it. (See the Link for the report.) drivers/net/wireless/intel/iwlwifi/fw/dbg.c:86: warning: Excess struct/union/enum/typedef member 'trans_len' description in 'iwl_fw_dump_ptrs' I patched that warning away even though I could not reproduce the warning from kernel-doc.

2023-10-30scripts/kernel-doc: Fix the regex for matching -Werror flagYujie Liu1-1/+1
Swarup reported a "make htmldocs" warning: Variable length lookbehind is experimental in regex; marked by <-- HERE in m/(?<=^|\s)-Werror(?=$|\s) <-- HERE / at ./scripts/kernel-doc line 188. Akira managed to reproduce it by perl v5.34.0. On second thought, it is not necessary to have the complicated "lookahead and lookbehind" things, and the regex can be simplified. Generally, the kernel-doc warnings should be considered as errors only when "-Werror" flag is set in KCFLAGS, but not when "-Werror=<diagnostic-type>" is set, which means there needs to be a space or start of string before "-Werror", and a space or end of string after "-Werror". The following cases have been tested to work as expected: * kernel-doc warnings are considered as errors: $ KCFLAGS="-Werror" make W=1 $ KCFLAGS="-Wcomment -Werror" make W=1 $ KCFLAGS="-Werror -Wundef" make W=1 $ KCFLAGS="-Wcomment -Werror -Wundef" make W=1 * kernel-doc warnings remain as warnings: $ KCFLAGS="-Werror=return-type" make W=1 $ KCFLAGS="-Wcomment -Werror=return-type" make W=1 $ KCFLAGS="-Werror=return-type -Wundef" make W=1 $ KCFLAGS="-Wcomment -Werror=return-type -Wundef" make W=1 The "Variable length lookbehind is experimental in regex" warning is also resolved by this patch.

2023-06-10kernel-doc: don't let V=1 change outcomeJohannes Berg1-5/+23
The kernel-doc script currently reports a number of issues only in "verbose" mode, but that's initialized from V=1 (via KBUILD_VERBOSE), so if you use KDOC_WERROR=1 then adding V=1 might actually break the build. This is rather unexpected. Change kernel-doc to not change its behaviour wrt. errors (or warnings) when verbose mode is enabled, but rather add separate warning flags (and -Wall) for it. Allow enabling those flags via environment/make variables in the kernel's build system for easier user use, but to not have to parse them in the script itself.

2023-06-05docs: scripts: kernel-doc: accept bitwise negation like ~@varMark Rutland1-1/+1
In some cases we'd like to indicate the bitwise negation of a parameter, e.g. ~@var This will be helpful for describing the atomic andnot operations, where we'd like to write comments of the form: Atomically updates @v to (@v & ~@i) Which kernel-doc currently transforms to: Atomically updates **v** to (**v** & ~**i**) Rather than the preferable form: Atomically updates **v** to (**v** & **~i**) This is similar to what we did for '!@var' in commit: ee2aa7590398 ("scripts: kernel-doc: accept negation like !@var") This patch follows the same pattern that commit used to permit a '!' prefix on a param ref, allowing a '~' prefix on a param ref, cuasing kernel-doc to generate the preferred form above.

Commit 43756e347f21 ("scripts/kernel-doc: Add support for named variable macro arguments") improved how named variable macro arguments are handled, and changed how they are documented in kerneldoc comments from "@param...", to "@param", deprecating the old syntax.

It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO container) which is the VFIO specific interface for a similar idea. We see a broad need for extended features, some being highly IOMMU device specific: - Binding iommu_domain's to PASID/SSID - Userspace IO page tables, for ARM, x86 and S390 - Kernel bypassed invalidation of user page tables - Re-use of the KVM page table in the IOMMU - Dirty page tracking in the IOMMU - Runtime Increase/Decrease of IOPTE size - PRI support with faults resolved in userspace Many of these HW features exist to support VM use cases - for instance the combination of PASID, PRI and Userspace IO Page Tables allows an implementation of DMA Shared Virtual Addressing (vSVA) within a guest. Dirty tracking enables VM live migration with SRIOV devices and PASID support allow creating "scalable IOV" devices, among other things. As these features are fundamental to a VM platform they need to be uniformly exposed to all the driver families that do DMA into VMs, which is currently VFIO and VDPA" For more background, see the extended explanations in Jason's pull request: https://lore.kernel.org/lkml/Y5dzTU8dlmXTbzoJ@nvidia.com/ * tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd: (62 commits) iommufd: Change the order of MSI setup iommufd: Improve a few unclear bits of code iommufd: Fix comment typos vfio: Move vfio group specific code into group.c vfio: Refactor dma APIs for emulated devices vfio: Wrap vfio group module init/clean code into helpers vfio: Refactor vfio_device open and close vfio: Make vfio_device_open() truly device specific vfio: Swap order of vfio_device_container_register() and open_device() vfio: Set device->group in helper function vfio: Create wrappers for group register/unregister vfio: Move the sanity check of the group to vfio_create_group() vfio: Simplify vfio_create_group() iommufd: Allow iommufd to supply /dev/vfio/vfio vfio: Make vfio_container optionally compiled vfio: Move container related MODULE_ALIAS statements into container.c vfio-iommufd: Support iommufd for emulated VFIO devices vfio-iommufd: Support iommufd for physical VFIO devices vfio-iommufd: Allow iommufd to be used in place of a container fd vfio: Use IOMMU_CAP_ENFORCE_CACHE_COHERENCY for vfio_file_enforced_coherent() ...

2022-06-13scripts: kernel-doc: Always increment warnings counterNiklas Söderlund1-47/+35
Some warnings do not increment the warnings counter making the behavior of running kernel-doc with -Werror unlogical as some warnings will be generated but not treated as errors. Fix this by creating a helper function that always incrementing the warnings counter every time a warning is emitted. There is one location in get_sphinx_version() where a warning is not touched as it concerns the execution environment of the kernel-doc and not the documentation being processed. Incrementing the counter only have effect when running kernel-doc in either verbose mode (-v or environment variable KBUILD_VERBOSE) or when treating warnings as errors (-Werror or environment variable KDOC_WERROR). In both cases the number of warnings printed is printed to stderr and for the later the exit code of kernel-doc is non-zero if warnings where encountered. Simple test case to demo one of the warnings, $ cat test.c /** * foo() - Description */ int bar(); # Without this change $ ./scripts/kernel-doc -Werror -none test.c test.c:4: warning: expecting prototype for foo(). Prototype was for bar() instead # With this change $ ./scripts/kernel-doc -Werror -none test.c test.c:4: warning: expecting prototype for foo().
