9958d30f - media: Kconfig: cleanup VIDEO_DEV dependencies

Sun, 13 Mar 2022 06:25:46 +0000

media: Kconfig: cleanup VIDEO_DEV dependenciesmedia Kconfig has two entries associated to V4L API:VIDEO_DEV and VIDEO_V4L2.On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core.while VIDEO_V4L2 where used to distinguish between drivers thatimplement the newer API and drivers that implemented the former one.With time, such meaning changed, specially after the removal ofall V4L version 1 drivers.At the current implementation, VIDEO_DEV only does (1): it enablesthe media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenubut it doesn't affect anymore the V4L core drivers.The rationale is that the V4L2 core has a "soft" dependencyat the I2C bus, and now requires to select a number of otherKconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEVIn the past, merging them would be tricky, but it seems that it is nowpossible to merge those symbols, in order to simplify V4L dependencies.Let's keep VIDEO_DEV, as this one is used on some make *defconfigconfigurations.Suggested-by: Laurent Pinchart Reviewed-by: Laurent Pinchart Reviewed-by: Jacopo Mondi Reviewed-by: Neil Armstrong # for meson-vdec & meson-ge2dAcked-by: Andrzej Pietrasiewicz Acked-by: Łukasz Stelmach Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/dvb-core/Kconfig

e58be016 - media: dvb-core: Kconfig: default to use dynamic minors

Wed, 25 Mar 2020 14:01:25 +0000

media: dvb-core: Kconfig: default to use dynamic minorsAll modern Linux distributions nowadays use udev or somealternative (like systemd). So, it makes sense to changethe 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 List of files: /linux-6.15/drivers/media/dvb-core/Kconfig

2f39cce9 - media: remove redundant 'default n' from Kconfig-s

Fri, 12 Apr 2019 10:27:40 +0000

media: remove redundant 'default n' from Kconfig-s'default n' is the default value for any bool or tristate Kconfigsetting so there is no need to write it explicitly.Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOOis not set' for visible symbols") the Kconfig behavior is the sameregardless 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. ...Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/dvb-core/Kconfig

ba711e1c - media: dvb-core: allow users to enable DVB net ULE debug

Mon, 11 Dec 2017 16:37:26 +0000

media: dvb-core: allow users to enable DVB net ULE debugThis debug option is there for a long time, but it is onlyenabled by editing the source code. Due to that, a breakageinside its code was only noticed years after a change atthe ULE handling logic.Make it a Kconfig parameter, as it makes easier foradvanced users to enable, and allow test if the compilationwon't be broken in the future.Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/dvb-core/Kconfig

90866b3a - [media] Raise adapter number limit

Tue, 05 Apr 2016 16:14:10 +0000

[media] Raise adapter number limitThe current limit is too low for latest cards with 8+ tuners on a single slot.IMHO, the most appropriate minimum default is 16.Signed-off-by: Буди Романто, AreMa Inc Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/dvb-core/Kconfig

bbd02f6a - [media] dvb_demux: convert an internal ifdef into a Kconfig option

Thu, 13 Oct 2016 09:57:47 +0000

[media] dvb_demux: convert an internal ifdef into a Kconfig optionThere are some ifdefs inside the dvb_demux that are meant toenable advanced debug capabilities, at the cost of being veryverbose.Keeping those as internal ifdefs is a very bad idea, as itdoesn't make easy to check if the code there was broken bysome patch. So, let's add an explicit Kconfig option for it.Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/dvb-core/Kconfig
