2018-09-17media: v4l2: taint pads with the signal types for consumer devicesMauro Carvalho Chehab
Consumer devices are provided with a wide different range of types supported by the same driver, allowing different configutations. In order to make easier to setup media controller links, "taint" pads with the signal type it carries. While here, get rid of DEMOD_PAD_VBI_OUT, as the signal it carries is actually the same as the normal video output. The difference happens at the video/VBI interface: - for VBI, only the hidden lines are streamed; - for video, the stream is usually cropped to hide the vbi lines.

2016-10-21[media] saa7134: 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>

2016-02-10[media] saa7134: use input types, instead of hardcoding stringsMauro Carvalho Chehab
Currently, the saa7134 driver is hardcoding input names on each board entry. More modern drivers define, instead, an enum for each input type. While the current logic works, it adds extra complexity at the driver, as it needs to discover the type of the input using some euristics. Instead, let's standardize the input types and use a type, instead of a name on all places. That will allow further patches to properly report the input type via VIDIOC_G_INPUT and to remove an extra field from the struct to identify if the input is for TV. Please notice that several boards define an input for receiving composite signals via a S-Video connector. The name of such input was inconsistent, so this patch cleans it and make it to be properly reported the same way for all boards. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2015-05-13[media] saa7134: avoid complex macro warningsMauro Carvalho Chehab

2015-05-13[media] saa7134: better handle core debug messagesMauro Carvalho Chehab
On media drivers, debugging messages should be grouped into categories, as this makes easier to debug the driver. In the case of saa7134, the core has 2 debug categories, one for IRQ, and another one for the core itself. The IRQ have actually 2 levels of debug. So, instead of using pr_dbg(), where everything would be in the same box, let's define two macros that use pr_fmt(), one for the core, and another one for irq. With that, we can replace the remaining printk() occurrences at the core to use either core_dbg() or irq_dbg(), depending on the group of debug macros that need to be enabled.

2014-05-23[media] saa7134: convert to vb2Hans Verkuil
Convert the saa7134 driver to vb2. Note that while this uses the vb2-dma-sg version, the VB2_USERPTR mode is disabled. The DMA hardware only supports DMAing full pages, and in the USERPTR memory model the first and last scatter-gather buffer is almost never a full page. In practice this means that we can't use the VB2_USERPTR mode. This has been tested with raw video, compressed video, VBI, radio, DVB and video overlays. Unfortunately, a vb2 conversion is one of those things you cannot split up in smaller patches, it's all or nothing. This patch switches the whole driver over to vb2, using the vb2 ioctl and fop helper functions.

2012-10-07Merge branch 'v4l_for_linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: "The first part of the media updates for Kernel 3.7. This series contain: - A major tree renaming patch series: now, drivers are organized internally by their used bus, instead of by V4L2 and/or DVB API, providing a cleaner driver location for hybrid drivers that implement both APIs, and allowing to cleanup the Kconfig items and make them more intuitive for the end user; - Media Kernel developers are typically very lazy with their duties of keeping the MAINTAINERS entries for their drivers updated. As now the tree is more organized, we're doing an effort to add/update those entries for the drivers that aren't currently orphan; - Several DVB USB drivers got moved to a new DVB USB v2 core; the new core fixes several bugs (as the existing one that got bitroted). Now, suspend/resume finally started to work fine (at least with some devices - we should expect more work with regards to it); - added multistream support for DVB-T2, and unified the API for DVB-S2 and ISDB-S. Backward binary support is preserved; - as usual, a few new drivers, some V4L2 core improvements and lots of drivers improvements and fixes. There are some points to notice on this series: 1) you should expect a trivial merge conflict on your tree, with the removal of Documentation/feature-removal-schedule.txt: this series would be adding two additional entries there. I opted to not rebase it due to this recent change; 2) With regards to the PCTV 520e udev-related breakage, I opted to fix it in a way that the patches can be backported to 3.5 even without your firmware fix patch. This way, Greg doesn't need to rush backporting your patch (as there are still the firmware cache and firmware path customization issues to be addressed there). I'll send later a patch (likely after the end of the merge window) reverting the rest of the DRX-K async firmware request, fully restoring its original behaviour to allow media drivers to initialize everything serialized as before for 3.7 and upper. 3) I'm planning to work on this weekend to test the DMABUF patches for V4L2. The patches are on my queue for several Kernel cycles, but, up to now, there is/was no way to test the series locally. I have some concerns about this particular changeset with regards to security issues, and with regards to the replacement of the old VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to GPU drivers change. The Overlay API allows direct PCI2PCI transfers from a media capture card into the GPU framebuffer, but its API is crappy. Also, the only existing X11 driver that implements it requires a XV extension that is not available anymore on modern drivers. The DMABUF can do the same thing, but with it is promising to be a properly-designed API.
