2023-05-17media: uapi: add MEDIA_BUS_FMT_METADATA_FIXED media bus format.Dafna Hirschfeld
[ Upstream commit 6ad253cc3436269fc6bcff03d704c672f368da0a ] MEDIA_BUS_FMT_METADATA_FIXED should be used when the same driver handles both sides of the link and the bus format is a fixed metadata format that is not configurable from userspace. The width and height will be set to 0 for this format.

2018-02-26media: v4l: doc: Clarify v4l2_mbus_fmt height definitionKieran Bingham
The v4l2_mbus_fmt width and height corresponds directly with the v4l2_pix_format definitions, yet the differences in documentation make it ambiguous what to do in the event of field heights. Clarify this using the same text as is provided for the v4l2_pix_format which is explicit on the matter, and by matching the terminology of 'image height' rather than the misleading 'frame height'.

2017-08-26media: fix pdf build with Spinx 1.6Mauro Carvalho Chehab
Sphinx 1.6 generates some LaTeX code before each table, starting its own environment before calling tabulary, apparently to improve table layout. The problem is that such environment is incompatible with adjustbox. While, in thesis, it should be possible to override it or to redefine tabulary, I was unable to produce such patch. Also, that would likely break on some future Sphinx version. So, instead, let's just change the font size on bigger tables, in order for them to fit into the page size. That is not as good as adjustbox, and require some manual work, but it should be less sensitive to Sphinx changes. While here, adjust a few other tables whose text is exceeding the cell boundaries.

2017-04-19[media] subdev-formats.rst: remove spurious '-'Hans Verkuil
Remove spurious duplicate '-' in the Bayer Formats description. This resulted in a weird dot character that also caused the row to be double-height. The - character was probably used originally as indicator of an unused bit, but as the number of columns was increased it was never used for the new columns. Other tables do not use '-' either, so just remove it.

2016-11-16docs-rst: auto-generate PDF image filesMauro Carvalho Chehab
The PDF files that contain media images were actually generated offline from their SVG or PNG source files. Sphinx can handle PNG sources automatially. So, let's just drop their PDF counterparts. For SVG, however, Sphinx doesn't produce the right tags to use the TexLive SVG support. Also, the SVG support is done via shell execution, with is not nice. So, while we don't have any support for SVG inside Sphinx core or as an extension, move the logic to build them to Makefile, producing the PDF images on runtime. NOTE: due to the way Sphinx works, the PDF images should be generated inside the Kernel source tree, as otherwise Sphinx won't find it, not obeying what's specified by "O=" makefile parameter.

2016-08-22[media] subdev-formats.rst: adjust tables size for LaTeX outputMauro Carvalho Chehab
There are two big tables here that are very hard to adjust its size. The first one would fit into one page, but the latex.py logic at Sphinx auto-switches to longtable when there are more than 30 rows. There's no way to override without coding. The second one is really big, and won't fit on a single page. So, it has to use tiny font to fit. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-08-22[media] docs-rst: fix warnings introduced by LaTeX patchsetMauro Carvalho Chehab
Sphinx is really pedantic with respect to the order where table tags and references are created. Putting things at the wrong order causes troubles.

Fix mosto fo the tables there in order to make them fit at the page size. There are, however, two exceptions: RGB and YUV big tables, where adding the raw latex adjustbox caused the tables to not be properly formatted. I suspect that the problem is because those are long tables, but not really sure. The thing is that Sphinx lacks an "adjustbox" tag that would avoid the raw latex hacks.

2016-08-22[media] docs-rst: add tabularcolumns to all tablesMauro Carvalho Chehab
LaTeX doesn't handle too well auto-width on tables, and ReST markup requires an special tag to give it the needed hints. As we're using A4 paper, we have 17cm of useful spaces. As most media tables have widths, let's use it to generate the needed via the following perl script: my ($line_size, $table_header, $has_cols) = (17.5, 0, 0); my $out; my $header = ""; my @widths = (); sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) } while (<>) { if (!$table_header) { $has_cols = 1 if (m/..\s+tabularcolumns::/); if (m/..\s+flat-table::/) { $table_header = 1; $header = $_; next; } $out .= $_; next; } $header .= $_; @widths = split(/ /, $1) if (m/:widths:\s+(.*)/); if (m/^\n$/) { if (!$has_cols && @widths) { my ($tot, $t, $i) = (0, 0, 0); foreach my $v(@widths) { $tot += $v; }; $out .= ".. tabularcolumns:: |"; for ($i = 0; $i < scalar @widths - 1; $i++) { my $v = $widths[$i]; my $w = round(10 * ($v * $line_size) / $tot) / 10; $out .= sprintf "p{%.1fcm}|", $w; $t += $w; } my $w = $line_size - $t; $out .= sprintf "p{%.1fcm}|\n\n", $w; } $out .= $header; $table_header = 0; $has_cols = 0; $header = ""; @widths = (); } } print $out; Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
