2016-09-09[media] diff-v4l.rst: Fix V4L version 1 referencesMauro Carvalho Chehab
The V4L version 1 structures had long gone from the Linux Kernel. It doesn't make sense to use cross-references for them, as they won't be found. So, get rid of them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] docs-rst: convert uAPI structs to C domainMauro Carvalho Chehab
instead of declaring the uAPI structs using usual refs, e. g.: .. _foo-struct: Use the C domain way: .. c:type:: foo_struct This way, the kAPI documentation can use cross-references to point to the uAPI symbols. That solves about ~100 undefined warnings like: WARNING: c:type reference target not found: foo_struct Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] conf_nitpick.py: ignore external functions used on mediactlMauro Carvalho Chehab
There are some functions/macros used by the mediactl documentation that are alien to the media subsystem. Ignore them. After this patch, the media core will only complain about this static function: Documentation/media/kapi/mc-core.rst:97: WARNING: c:func reference target not found: media_devnode_release Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] mc-core.rst: Fix cross-references to the sourceMauro Carvalho Chehab
The cross-reference to "struct media_pad" was pointing to a place that doesn't exist. Fix it, and adjust the second reference on the same paragraph to use the same text. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] dtv-core.rst: move DTV ringbuffer notes to kAPI docMauro Carvalho Chehab

2016-09-09[media] conf_nitpick.py: add external vars to ignore listMauro Carvalho Chehab

2016-09-09[media] docs-rst: parse-headers.pl: use the C domain for cross-referencesMauro Carvalho Chehab
Instead of keep using the normal reference, move to the C domain ones. Using C domains everywhere will allow cross-references between kAPI and uAPI docs. Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2016-09-01doc-rst: generic way to build PDF of sub-foldersMarkus Heiser
This extends the method to build only sub-folders to the targets "latexdocs" and "pdfdocs". To do so, a conf.py in the sub-folder is required, where the latex_documents of the sub-folder are defined. E.g. to build only gpu's PDF add the following to the Documentation/gpu/conf.py:: +latex_documents = [ + ("index", "gpu.tex", "Linux GPU Driver Developer's Guide", + "The kernel development community", "manual"), +] and run: make SPHINXDIRS=gpu pdfdocs Signed-off-by: Markus Heiser <markus.heiser@darmarIT.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2016-09-01docs: sphinx-extensions: add metadata parallel-safeMarkus Heiser
The setup() function of a Sphinx-extension can return a dictionary. This is treated by Sphinx as metadata of the extension [1]. With metadata "parallel_read_safe = True" a extension is marked as save for "parallel reading of source". This is needed if you want build in parallel with N processes. E.g.: make SPHINXOPTS=-j4 htmldocs will no longer log warnings like: WARNING: the foobar extension does not declare if it is safe for parallel reading, assuming it isn't - please ask the extension author to check and make it explicit. Add metadata to extensions: * kernel-doc * flat-table * kernel-include [1] http://www.sphinx-doc.org/en/stable/extdev/#extension-metadata Signed-off-by: Markus Heiser <markus.heiser@darmarIT.de> Tested-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2016-08-25docs: kernel-parameter: Improve the description of nr_cpus and maxcpusBaoquan He
From the old description people still can't get what's the exact difference between nr_cpus and maxcpus. Especially in kdump kernel nr_cpus is always suggested if it's implemented in the ARCH. The reason is nr_cpus is used to limit the max number of possible cpu in system, the sum of already plugged cpus and hot plug cpus can't exceed its value. However maxcpus is used to limit how many cpus are allowed to be brought up during bootup. Signed-off-by: Baoquan He <bhe@redhat.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

The SYCC Y'CbCr encoding is identical to the 601 encoding. Since the SYCC define is about to be removed for use in the kernel we need to drop it in the TPG code as well. This patch also adds a 4th decimal to the 601 conversion matrix. That was specified by the sYCC spec and it makes sense to use this across the board.
