2020-04-14media: Kconfig: move V4L2 subdev API to v4l2-core/KconfigMauro Carvalho Chehab
This option is part of V4L2 API extra functionality set. Move it to be at the v4l2-core/Kconfig, where it belongs, cleaning the main Kconfig file. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: move DVB-specific options to dvb-core/KconfigMauro Carvalho Chehab
In order to cleanup the main media Kconfig, move the DVB-core specific options to dvb-core/Kconfig. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: move CEC-specific options to cec/KconfigMauro Carvalho Chehab
There's no need to have the CEC definitions inside the media Kconfig, as the Kconfig parser doesn't require symbols to be declared before their usages. With that, the main Kconfig menu becomes cleaner. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: warn if drivers are filteredMauro Carvalho Chehab
As per a tester feedback, add an option to report when the drivers are filtered at the Kconfig menu. Cc: Helen Koike <helen.koike@collabora.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: make filtering devices optionalMauro Carvalho Chehab
The per-device option selection is a feature that some developers love, while others hate... So, let's make both happy by making it optional. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: use a sub-menu to select supported devicesMauro Carvalho Chehab
The media subsystem has hundreds of driver-specific options. The *_SUPPORT config options work as a sort of filter, allowing to reduce its complexity for users that won't want to dig into thousands of options they don't need. Yet, it the filtering options are becoming large. So, let's place it on a sub-menu. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: reorganize the drivers menu optionsMauro Carvalho Chehab
The comments before some of the drivers support look weird, because their Kconfig have their own "comment" directive inside it. So, rearrange them to make it look a little nicer for the ones with are not too familiar with the media system. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig files: use select for V4L2 subdevs and MCMauro Carvalho Chehab
There are lots of drivers that only work when the media controller and/or the V4L2 subdev APIs are present. Right now, someone need to first enable those APIs before using those drivers. Well, ideally, drivers, should, instead *optionally* depend on it, in order for PC camera drivers to be able to use them, but nowadays most drivers are UVC cameras, with don't require a sensor driver. So, be it. Let's instead make them select the MEDIA_CONTROLLER and the SUBDEV API, in order to make easier for people to be able of enabling them.

2020-04-14media: dvb-core: Kconfig: default to use dynamic minorsMauro Carvalho Chehab
All modern Linux distributions nowadays use udev or some alternative (like systemd). So, it makes sense to change the default to use dynamic minors. Please notice that this default doesn't enable any code. It just changes the dvb-core behavior. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: add SPDX headers on Kconfig and Makefile filesMauro Carvalho Chehab
Most of media Kconfig/Makefile files already has SPDX, but there are a few ones still missing. Add it to them. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: fix selection for test driversMauro Carvalho Chehab
There are some long-time mistakes related to build test drivers, with regards to depends on/select. Also, as we now want to build any test driver without needing to enable anything else, change the logic in order to properly filter them. Please notice that the PCI skeleton is somewhat an exception, as it requires to select *both* SAMPLES and MEDIA_TEST_SUPPORT. I almost changed it to be either one, but decided to keep it as-is, as this is something that we don't really need to be included on any distribution. The only reason for someone to build it is for COMPILE_TEST purposes. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: better support hybrid TV devicesMauro Carvalho Chehab
Right now, if one has an hybrid TV card, it has to select both analog and digital TV support, as otherwise the needed core support won't be selected. Change the logic to auto-select the core support for those drivers, as this is a way more intuitive. It should be noticed that, as now both DVB_CORE and VIDEO_DEV defaults depends on selecting a hybrid cards, we had to remove the explicit dependencies there, in order to avoid circular dependencies. That requires some tricks: 1) the prompt should not be not visible when an hybrid card is selected, as the user shold not change it. 2) When a media hybrid device is selected, the modular option for DVB_CORE and VIDEO_DEV will follow the MEDIA_SUPPORT dependency, as we can't have a core built with "y" with a driver built as module. Note: while here, moved two pure V4L2 PCI drivers out of the "hybrid" part of config and consider pvrusb2 as an hybrid device. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: simplify some dependenciesMauro Carvalho Chehab
both DVB_CORE and VIDEO_DEV already depends on MEDIA_SUPPORT, as they're below an if block. So, remove this double dependency. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: mark other drivers as test driversMauro Carvalho Chehab
Neither the PCI skeleton nor the DVB dummy driver are real drivers. They're there just as an example for a driver writter. Distros should not enable those drivers. So, hide them if MEDIA_TEST_SUPPORT is not selected. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: ddbridge: use the ddbridge's own dummy fe driverMauro Carvalho Chehab
Cleanup the ddbridge's dummy driver by removing the parts that aren't needed by ddbridge, adding it to the building system and changing the binding at the driver to use the newer function name. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: ddbridge-dummy_fe: do some vars and function renamesMauro Carvalho Chehab

2020-04-14media: ddbridge: copy the dvb_dummy_fe driver to ddbridgeMauro Carvalho Chehab
As we'll be transforming the dvb-dummy-fe driver soon into a virtual driver, let's first copy the existing one to ddbridge as-is, as it is needed there. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2020-04-14media: Kconfig: move drivers-specific TTPCI_EEPROM Kconfig varMauro Carvalho Chehab
This option is used only by av7110 and by an USB driver. As the av7110 is the first DVB hardware, hardly found those days, let's opt to place it at usb/Kconfig, as the driver with needs it might have a longer lifetime. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: move comment to siano includeMauro Carvalho Chehab
Showing this comment without showing the Siano mmc option is very weird! Place the option together, and make it visible only when showing Siano configuration. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: split test drivers from platform directoryMauro Carvalho Chehab
When the first test device was added (vivi.c), there were just one file. I was too lazy on that time to create a separate directory just for it, so I kept it together with platform. Now, we have vivid, vicodec, vim2m and vimc. Also, a new virtual driver has been prepared to support DVB API. So, it is time to solve this mess, by placing test stuff on a separate directory. It should be noticed that we also have some skeleton drivers (for V4L and for DVB). For now, we'll keep them separate, as they're not really test drivers, but instead, just examples. The DVB frontend ones will likely be part of a new DVB test driver. By that time, it should make sense to move them here as well. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: update the MEDIA_SUPPORT help messageMauro Carvalho Chehab

2020-04-14media: pci: move VIDEO_PCI_SKELETON to a different KconfigMauro Carvalho Chehab
The V4L2 PCI skeleton is not part of the V4L2 core. Move it to appear together with the other PCI drivers, at the end, as this is something that normal users don't even need to bother. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: not all V4L2 platform drivers are for cameraMauro Carvalho Chehab
When the platform drivers got added, they were all part of complex camera support. This is not the case anymore, as we now have codecs and other stuff there too. So, fix the dependencies, in order to not require users to manually select something that it doesn't make sense. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: add an option to filter in/out platform driversMauro Carvalho Chehab

2020-04-14media: dvb-usb: auto-select CYPRESS_FIRMWAREMauro Carvalho Chehab
At least some of the supported boards by dvb-usb driver need to load the cypress firmware, so select it, as otherwise missing dependencies may popup. Also, as the cypress firmware load routines are needed only by the dvb-usb, dvb-usb-v2 and go7007 drivers, and those all (now) select it, there's no need to ask the user for manually select it.

2020-04-12MAINTAINERS: sort field names for all entriesLinus Torvalds
This sorts the actual field names too, potentially causing even more chaos and confusion at merge time if you have edited the MAINTAINERS file. But the end result is a more consistent layout, and hopefully it's a one-time pain minimized by doing this just before the -rc1 release. This was entirely scripted: ./scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS --order Requested-by: Joe Perches <joe@perches.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2020-04-12MAINTAINERS: sort entries by entry nameLinus Torvalds
They are all supposed to be sorted, but people who add new entries don't always know the alphabet. Plus sometimes the entry names get edited, and people don't then re-order the entry. Let's see how painful this will be for merging purposes (the MAINTAINERS file is often edited in various different trees), but Joe claims there's relatively few patches in -next that touch this, and doing it just before -rc1 is likely the best time. Fingers crossed. This was scripted with /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS but then I also ended up manually upper-casing a few entry names that stood out when looking at the end result.

Emulate split-lock accesses as writes if split lock detection is on to avoid #AC during emulation, which will result in a panic().

Without at least minimal handling for split lock detection induced #AC, VMX will just run into the same problem as the VMWare hypervisor, which was reported by Kenneth. It will inject the #AC blindly into the guest whether the guest is prepared or not. Provide a function for guest mode which acts depending on the host SLD mode.

git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux Pull orangefs updates from Mike Marshall: "A fix and two cleanups. Fix: - Christoph Hellwig noticed that some logic I added to orangefs_file_read_iter introduced a race condition, so he sent a reversion patch. I had to modify his patch since reverting at this point broke Orangefs. Cleanups: - Christoph Hellwig noticed that we were doing some unnecessary work in orangefs_flush, so he sent in a patch that removed the un-needed code. - Al Viro told me he had trouble building Orangefs. Orangefs should be easy to build, even for Al :-). I looked back at the test server build notes in orangefs.txt, just in case that's where the trouble really is, and found a couple of typos and made a couple of clarifications" * tag 'for-linus-5.7-ofs1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux: orangefs: clarify build steps for test server in orangefs.txt orangefs: don't mess with I_DIRTY_TIMES in orangefs_flush orangefs: get rid of knob code...
