2025-10-03Merge tag 'docs-6.18' of git://git.lwn.net/linuxLinus Torvalds2-2/+580
Pull documentation updates from Jonathan Corbet: "It has been a relatively busy cycle in docsland, with changes all over: - Bring the kernel memory-model docs into the Sphinx build in the "literal include" mode. - Lots of build-infrastructure work, further cleaning up long-term kernel-doc technical debt. The sphinx-pre-install tool has been converted to Python and updated for current systems. - A new tool to detect when documents have been moved and generate HTML redirects; this can be used on kernel.org (or any other site hosting the rendered docs) to avoid breaking links. - Automated processing of the YAML files describing the netlink protocol. - A significant update of the maintainer's PGP guide. ... and a seemingly endless series of typo fixes, build-problem fixes, etc" * tag 'docs-6.18' of git://git.lwn.net/linux: (193 commits) Documentation/features: Update feature lists for 6.17-rc7 docs: remove cdomain.py Documentation/process: submitting-patches: fix typo in "were do" docs: dev-tools/lkmm: Fix typo of missing file extension Documentation: trace: histogram: Convert ftrace docs cross-reference Documentation: trace: histogram-design: Wrap introductory note in note:: directive Documentation: trace: historgram-design: Separate sched_waking histogram section heading and the following diagram Documentation: trace: histogram-design: Trim trailing vertices in diagram explanation text Documentation: trace: histogram: Fix histogram trigger subsection number order docs: driver-api: fix spelling of "buses".

2025-08-29scripts: sphinx-build-wrapper: get rid of uapi/media MakefileMauro Carvalho Chehab2-2/+580
Now that kernel-include directive supports parsing data structs directly, we can finally get rid of the horrible hack we added to support parsing media uAPI symbols. As a side effect, Documentation/output doesn't have anymore media auto-generated .rst files on it.

2024-08-05media: cec: core: add new CEC_MSG_FL_REPLY_VENDOR_ID flagHans Verkuil2-0/+21
If this flag is set, then the reply is expected to consist of the CEC_MSG_VENDOR_COMMAND_WITH_ID opcode followed by the Vendor ID (as used in bytes 1-4 of the message), followed by the struct cec_msg reply field. Note that this assumes that the byte after the Vendor ID is a vendor-specific opcode. This flag makes it easier to wait for replies to vendor commands, using the same CEC framework support for waiting for regular replies. Support for this flag is indicated by setting the new CEC_CAP_REPLY_VENDOR_ID capability.

2024-04-24media: cec: return -ENODEV instead of -ENXIO if unregisteredHans Verkuil1-2/+2
If the CEC device is unregistered, then an attempt to open the device node should result in an -ENODEV error instead of -ENXIO. Document this as well in cec-func-open.rst. This is consistent with the error code returned by other file operations such as ioctl. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
2023-11-17media: doc: properly format ToC headingsVegard Nossum1-6/+1
"class:: toc-title" was a workaround for older Sphinx versions that are no longer supported. The canonical way to add a heading to the ToC is to use :caption:. Do that.

2022-11-25media: admin-guide: cec.rstHans Verkuil1-0/+2
Document administration details about CEC devices. This was formerly documented in a cec-status.txt I kept on my website, but this really belongs here as an admin guide. Updated the original cec-status.txt, and converted it to .rst. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2021-11-15media: cec-ioc-receive.rst: clarify sequence and status fieldsHans Verkuil1-23/+26
Improve the documentation for CEC_RECEIVE/TRANSMIT w.r.t. the sequence and tx/rx_status fields. Also remove a duplicate tx_status description. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2021-04-06media: cec/core: clarify rx-arb-lost usage messageHans Verkuil1-1/+1
The rx-arb-lost error injection command only works with <op> set to 'any'. Explicitly say so in the usage message. Also use [] to indicate that the <poll> argument is optional. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2021-03-11media: docs: uAPI: fix table output in LaTeX/PDF formatMauro Carvalho Chehab6-22/+22
There are lots of tables that are not properly displayed in LaTeX/PDF. Fix the tablecolumns, add longtable where needed and LaTeX formatting macros, in order to address such issues. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-11-16media: cec-core.rst/cec-ioc-g-mode.rst: fix typos in monitor-all descriptionHans Verkuil1-1/+1
cec-core.rst was missing 'are', and cec-ioc-g-mode.rst was missing a comma. In both cases this made the description of the Monitor All functionality hard to read. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-10-15media: docs: make CEC documents compatible with Sphinx 3.1+Mauro Carvalho Chehab11-87/+63
Sphinx 3.x broke support for the cdomain.py extension, as the c domain code was rewritten. Due to that, the c tags need to be re-written, in order to use the new c domain notation. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-09-01media: docs: use the new SPDX header for GFDL-1.1 on *.rst filesMauro Carvalho Chehab15-121/+15
SPDX v3.10 gained support for GFDL-1.1 with no invariant sections: https://spdx.org/licenses/GFDL-1.1-no-invariants-or-later.html So, remove the license text, replacing them by this new SPDX license. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2020-04-14media: docs: move uAPI book to userspace-api/mediaMauro Carvalho Chehab16-0/+2463
Since 2017, there is an space reserved for userspace API, created by changeset 1d596dee3862 ("docs: Create a user-space API guide"). As the media subsystem was one of the first subsystems to use Sphinx, until this patch, we were keeping things on a separate place. Let's just use the new location, as having all uAPI altogether will likely make things easier for developers. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
