2019-07-26media: marvell-ccic: fix DMA s/g desc number calculationLubomir Rintel
[ Upstream commit 0c7aa32966dab0b8a7424e1b34c7f206817953ec ] The commit d790b7eda953 ("[media] vb2-dma-sg: move dma_(un)map_sg here") left dma_desc_nent unset. It previously contained the number of DMA descriptors as returned from dma_map_sg(). We can now (since the commit referred to above) obtain the same value from the sg_table and drop dma_desc_nent altogether. Tested on OLPC XO-1.75 machine. Doesn't affect the OLPC XO-1's Cafe driver, since that one doesn't do DMA.

Randconfig builds fail when one of the two is a built-in driver and the other one is a loadable module: drivers/media/platform/marvell-ccic/mcam-core.o: In function `mccic_register': mcam-core.c:(.text+0x2594): undefined reference to `__this_module' drivers/media/platform/marvell-ccic/mcam-core.o:(.rodata+0x50): undefined reference to `__this_module' The problem is that mcam-core.c can not be built both ways at the smae time. However, we can make kbuild take care of that by making the core driver a separate module, which can be either built-in or loadable as needed. Making it a separate module requires exporting a few symbols and adding the module license from the header.

2018-05-28media: Remove depends on HAS_DMA in case of platform dependencyGeert Uytterhoeven
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing. Note: - The various VIDEOBUF*DMA* symbols had to loose their dependencies on HAS_DMA, as they are selected by several individual drivers.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

2016-10-21[media] marvell-ccic: don't break long linesMauro Carvalho Chehab
Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2015-12-18[media] vb2: drop v4l2_format argument from queue_setupHans Verkuil
The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2015-11-17[media] include/media: split I2C headers from V4L2 coreMauro Carvalho Chehab
Currently, include/media is messy, as it contains both the V4L2 core headers and some driver-specific headers on the same place. That makes harder to identify what core headers should be documented and what headers belong to I2C drivers that are included only by bridge/main drivers that would require the functions provided by them. Let's move those i2c specific files to its own subdirectory. The files to move were produced via the following script: mkdir include/media/i2c (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done And the references corrected via this script: MAIN_DIR="media/" PREV_DIR="media/" DIRS="i2c/" echo "Checking affected files" >&2 for i in $DIRS; do for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do n=`basename $j` git grep -l $n done done|sort|uniq >files && ( echo "Handling files..." >&2; echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done"; ); echo "Handling documentation..." >&2; echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done" ); ) >script && . ./script Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.

The RGB444 format swapped the red and blue components, fix this. Rather than making a new BGR444 format (as I proposed initially), Jon prefers to just fix this and return the colors in the right order. I think that makes sense in this case. Since the RGB444 pixel format is deprecated due to the ambiguous specification of the alpha component we use the XRGB444 pixel format instead (specified as having no alpha channel).

Various formats had their byte ordering implemented incorrectly, and the V4L2_PIX_FMT_UYVY is actually impossible to create, instead you get V4L2_PIX_FMT_YVYU. This was working before commit ad6ac452227b7cb93ac79beec092850d178740b1 ("add new formats support for marvell-ccic driver"). That commit broke the original format support and the OLPC XO-1 laptop showed wrong colors ever since (if you are crazy enough to attempt to run the latest kernel on it, like I did). The email addresses of the authors of that patch are no longer valid, so without a way to reach them and ask them about their test setup I am going with what I can test on the OLPC laptop. If this breaks something for someone on their non-OLPC setup, then contact the linux-media mailinglist. My suspicion however is that that commit went in untested.
