media: dvb: fix DVB_MMAP dependency

2018-02-23T10:21:41+00:00

Enabling CONFIG_DVB_MMAP without CONFIG_VIDEOBUF2_VMALLOC results in a link error: drivers/media/dvb-core/dvb_vb2.o: In function `_stop_streaming': dvb_vb2.c:(.text+0x894): undefined reference to `vb2_buffer_done' drivers/media/dvb-core/dvb_vb2.o: In function `dvb_vb2_init': dvb_vb2.c:(.text+0xbec): undefined reference to `vb2_vmalloc_memops' dvb_vb2.c:(.text+0xc4c): undefined reference to `vb2_core_queue_init' drivers/media/dvb-core/dvb_vb2.o: In function `dvb_vb2_release': dvb_vb2.c:(.text+0xe14): undefined reference to `vb2_core_queue_release' drivers/media/dvb-core/dvb_vb2.o: In function `dvb_vb2_stream_on': dvb_vb2.c:(.text+0xeb8): undefined reference to `vb2_core_streamon' drivers/media/dvb-core/dvb_vb2.o: In function `dvb_vb2_stream_off': dvb_vb2.c:(.text+0xfe8): undefined reference to `vb2_core_streamoff' drivers/media/dvb-core/dvb_vb2.o: In function `dvb_vb2_fill_buffer': dvb_vb2.c:(.text+0x13ec): undefined reference to `vb2_plane_vaddr' dvb_vb2.c:(.text+0x149c): undefined reference to `vb2_buffer_done' This adds a 'select' statement for it, plus a dependency that ensures that videobuf2 in turn works, as it in turn depends on VIDEO_V4L2 to link, and that must not be a module if videobuf2 is built-in.

media: fix usage of whitespaces and on indentation

2018-01-04T18:12:01+00:00

On several places, whitespaces are being used for indentation, or even at the end of the line. Fix them. Signed-off-by: Mauro Carvalho Chehab

media: dvb-core: make DVB mmap API optional

2017-12-28T16:17:29+00:00

This API is still experimental. Make it optional, allowing to compile the code without it. Signed-off-by: Mauro Carvalho Chehab

media: rc-core: do not depend on MEDIA_SUPPORT

2017-08-20T13:39:36+00:00

There is no dependency between the two, so remove the dependency in Kconfig files. Signed-off-by: Sean Young Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec-pin: add low-level pin hardware support

2017-07-18T15:57:18+00:00

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. Signed-off-by: Hans Verkuil Reviewed-by: Maxime Ripard Signed-off-by: Mauro Carvalho Chehab

[media] cec: rename MEDIA_CEC_NOTIFIER to CEC_NOTIFIER

2017-06-04T18:23:35+00:00

This config option is strictly speaking independent of the media subsystem since it can be used by drm as well. Besides, it looks odd when drivers select CEC_CORE and MEDIA_CEC_NOTIFIER, that's inconsistent naming. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] cec: select CEC_CORE instead of depend on it

2017-06-04T18:23:33+00:00

The CEC framework is used by both drm and media. That makes it tricky to get the dependencies right. This patch moves the CEC_CORE and MEDIA_CEC_NOTIFIER config options out of the media menu and instead drivers that want to use CEC should select CEC_CORE and MEDIA_CEC_NOTIFIER (if needed).

[media] cec: Kconfig cleanup

2017-04-19T09:50:52+00:00

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.

[media] media: add CEC notifier support

2017-04-10T15:48:28+00:00

Add support for CEC notifiers, which is used to convey CEC physical address information from video drivers to their CEC counterpart driver(s). Based on an earlier version from Russell King: https://patchwork.kernel.org/patch/9277043/ The cec_notifier is a reference counted object containing the CEC physical address state of a video device. When a new notifier is registered the current state will be reported to that notifier at registration time.
