* media: Clarify how menus are hidden by SUBDRV_AUTOSELECTEzequiel Garcia2019-08-191-0/+5
| | | | | | | | | | | | | | | | | | | | | Some users have been having a hard time finding the hidden menus. A typically case are camera sensor drivers (e.g IMX219, OV5645, etc), which are common on embedded platforms and not really "ancillary" devices. The problem with MEDIA_SUBDRV_AUTOSELECT seems to be related to the fact that it uses the "visible" syntax to hide the menus. This is not obvious and it normally takes some time to figure out. To fix the problem, add a comment on each of hidden menus, which should clarify what option is causing menus to be hidden.

* media: Don't default-enable "ancillary driver autoselect" if EMBEDDEDEzequiel Garcia2019-07-251-1/+1
| | | | | | | | | | | | | | | Admittedly, it's not easy to say what CONFIG_EMBEDDED really should be doing, just as it's not easy to say what is "embedded". In any case, the very description of MEDIA_SUBDRV_AUTOSELECT specifies that embedded systems usually don't want to enable this autoselect option. Therefore, drop the default-yes, when the CONFIG_EMBEDDED is chosen.

* media: move drivers/media/media-* to drivers/media/mc/mc-*Hans Verkuil2019-05-281-33/+1
| | | | | | | | | | | | | | It is really weird that the media controller sources are all top-level in drivers/media. It is a bit of a left-over from long ago when most media sources were all at the top-level. At some point we reorganized the directory structure, but the media-*.c sources where never moved to their own directory. So create a new mc directory and move all sources there. Also rename the prefix from media- to mc-. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

* media: cec-pin: add low-level pin hardware supportHans Verkuil2017-07-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for CEC hardware that relies on low-level pin polling or GPIO interrupts. One example is the Allwinner SoC. But any GPIO-based CEC implementation can use this as well. A GPIO implementation is very suitable as well for debugging: it can use interrupts to detect state changes and report it. Userspace can then verify if the bus traffic is correct. This also makes error injection possible. The disadvantage is that it is hard to get the timings right since linux isn't a hard realtime system. In general on an idle system it works quite well, but under load the timer will miss its mark every so often. The debugfs file /sys/kernel/debug/cec/cecX/status gives some statistics with respect to the timer overruns. When the adapter is unconfigured and the low-level driver supports interrupts, then the interrupt will be used to detect changes. This should be quite accurate. But when the adapter is configured a hrtimer has to be used. The hrtimer implements a state machine where for each state the code will read the bus or drive the bus and go on to the next state. It will re-arm the timer with a delay based on the next state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig options for the CEC subsystem were a bit messy. In addition there were two cec sources (cec-edid.c and cec-notifier.c) that were outside of the media/cec directory, which was weird. Move those sources to media/cec as well. The cec-edid and cec-notifier functionality is now part of the cec module and these are no longer separate modules. Also remove the MEDIA_CEC_EDID config option and include it with the main CEC config option (which defined CEC_EDID anyway). Added static inlines to cec-edid.h for dummy functions when CEC_CORE isn't defined. CEC drivers should now depend on CEC_CORE. CEC drivers that need the cec-notifier functionality must explicitly select CEC_NOTIFIER. The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of CEC_CORE, fix that as well.

* | Kconfig: disable Media Controller for DVBMauro Carvalho Chehab2015-06-181-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since when we start discussions about the usage Media Controller for complex hardware, one thing become clear: the way it is, MC fails to map anything different than capture/output/m2m video-only streaming. The point is that MC has entities named as devnodes, but the only devnode used (before the DVB patches) is MEDIA_ENT_T_DEVNODE_V4L. Due to the way MC got implemented, however, this entity actually doesn't represent the devnode, but the hardware I/O engine that receives data via DMA. By coincidence, such DMA is associated with the V4L device node on webcam hardware, but this is not true even for other V4L2 devices. For example, on USB hardware, the DMA is done via the USB controller. The data passes though a in-kernel filter that strips off the URB headers. Other V4L2 devices like radio may not even have DMA. When it have, the DMA is done via ALSA, and not via the V4L devnode. In other words, MC is broken as a whole, but tagging it as BROKEN right now would do more harm than good. So, instead, let's mark, for now, the DVB part as broken and block all new changes to MC while we fix this mess, whith we hopefully will do for the next Kernel version.

| | | | | | | | | | | | | | | | | | These drivers haven't been tested in a long, long time. The hardware is ancient and hopelessly obsolete. These drivers also need to be converted to newer media frameworks but due to the lack of hardware that's going to be impossible. In addition, cheaper and vastly better hardware is available today. So these drivers are a prime candidate for removal. If someone is interested in working on these drivers to prevent their removal, then please contact the linux-media mailinglist. Let's be honest, the age of parallel port webcams and ISA video capture boards is really gone.

* [media] Kconfig: do not select SPI bus on sub-driver auto-selectAntti Palosaari2014-09-041-1/+0
| | | | | | | | | | | | | | | | We should not select SPI bus when sub-driver auto-select is selected. That option is meant for auto-selecting all possible ancillary drivers used for selected board driver. Ancillary drivers should define needed dependencies itself. I2C and I2C_MUX are still selected here for a reason described on commit 347f7a3763601d7b466898d1f10080b7083ac4a3 Reverts commit e4462ffc1602d9df21c00a0381dca9080474e27a Reported-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

* [media] subdev autoselect only works if I2C and I2C_MUX is selectedMauro Carvalho Chehab2013-12-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by the kbuild test robot <fengguang.wu@intel.com>: > warning: (VIDEO_EM28XX_DVB) selects DVB_M88DS3103 which has unmet direct dependencies (MEDIA_SUPPORT && DVB_CORE && I2C && I2C_MUX) > drivers/built-in.o: In function `m88ds3103_release': > >> m88ds3103.c:(.text+0x1ab1af): undefined reference to `i2c_del_mux_adapter' > drivers/built-in.o: In function `m88ds3103_attach': > >> (.text+0x1ab342): undefined reference to `i2c_add_mux_adapter' There are 3 possible ways to fix it: 1) make em28xx dependent on I2C_MUX. That sounds wrong, as the em28xx bridge doesn't have i2c muxes on it, and just one frontend has. Well, subdevs could eventually be converted to, instead of using dvb i2c gate control, to use i2c mux support. That makes sense, but it takes time and lots of effort. Not sure if this will happen anytime soon. 2) MEDIA_SUBDRV_AUTOSELECT can be dependent of I2C and I2C_MUX. That means that users will need to manually enable I2C_MUX on some distributions. Not sure about others, but, on Fedora, this option is disabled. So, it can end by generating a number of complains from users that their devices suddenly stopped working after a Kernel upgrade, at least until all distros that ship Kernels with I2C_MUX enabled. 3) if MEDIA_SUBDRV_AUTOSELECT is selected, it will select I2C and I2C_MUX. Of course, MEDIA_SUBDRV_AUTOSELECT will need to inherit all dependencies that I2C and I2C_MUX have (only HAS_IOMEM). The disadvantage is that, if new dependencies are added on I2C, they'll also need to be added here. As the hole idea of autoselect is to let the user not bother about whatever frontend/tuner is used by a driver, IMHO, (3) is the better solution.

By enabling CONFIG_MEDIA_ATTACH, the configuration becomes valid, as dvb_attach() macro loads the module if needed, making the symbol available to the builtin module. While this bug started to appear after the patches that use IS_DEFINED macro (like changeset 7b34be71db533f3e0cf93d53cf62d036cdb5418a), this bug is a way ancient than that. The thing is that, before the IS_DEFINED() patches, the logic used to be: && defined(MODULE)) struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe, u8 i2c_addr, struct i2c_adapter *i2c); static inline struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe, u8 i2c_addr, struct i2c_adapter *i2c) { printk(KERN_WARNING "%s: driver disabled by Kconfig\n", __func__); return NULL; } The above code, with the .config file used, was evoluting to FALSE (instead of TRUE as it should be, as CONFIG_DVB_ZL10039 is 'm'), and were adding the static inline code at saa7134-dvb, instead of the external call. So, while it weren't producing any compilation error, the code weren't working either. So, as the overhead for using CONFIG_MEDIA_ATTACH is minimal, just enable it, if MODULES is defined.
