media: dvb/audio.h: get rid of unused APIs

2018-07-30T20:21:49Z

There are a number of other ioctls that aren't used anywhere inside the Kernel tree. Get rid of them. Signed-off-by: Mauro Carvalho Chehab

media: dvb: get rid of VIDEO_SET_SPU_PALETTE

2018-07-27T10:41:35Z

No upstream drivers use it. It doesn't make any sense to have a compat32 code for something that nobody uses upstream. Reported-by: Alexander Viro Signed-off-by: Mauro Carvalho Chehab Reviewed-by: Christoph Hellwig Signed-off-by: Mauro Carvalho Chehab

media: dvb: add continuity error indicators for memory mapped buffers

2018-02-23T10:28:41Z

While userspace can detect discontinuity errors, it is useful to also let Kernelspace reporting discontinuity, as it can help to identify if the data loss happened either at Kernel or userspace side. Update documentation accordingly. Signed-off-by: Mauro Carvalho Chehab

There are a lot of places where sequences of space/tabs are found. Get rid of all spaces before tabs. Signed-off-by: Mauro Carvalho Chehab

media: dvb-core: get rid of mmap reserved field

2017-12-28T16:17:31Z

The "reserved" field was a way, used at V4L2 API, to add new data to existing structs without breaking userspace. However, there are now clever ways of doing that, without needing to add an uneeded overhead. So, get rid of them. Signed-off-by: Mauro Carvalho Chehab

media: videobuf2: Add new uAPI for DVB streaming I/O

2017-12-28T15:59:02Z

Adds a new uAPI for DVB to use streaming I/O which is implemented based on videobuf2, using those new ioctls: - DMX_REQBUFS: Request kernel to allocate buffers which count and size are dedicated by user. - DMX_QUERYBUF: Get the buffer information like a memory offset which will mmap() and be shared with user-space. - DMX_EXPBUF: Just for testing whether buffer-exporting success or not. - DMX_QBUF: Pass the buffer to kernel-space. - DMX_DQBUF: Get back the buffer which may contain TS data. Originally developed by: Junghak Sung , as seen at: https://patchwork.linuxtv.org/patch/31613/ https://patchwork.kernel.org/patch/7334301/ The original patch was written before merging VB2-core functionalities upstream. When such series was added, several adjustments were made, fixing some issues with V4L2, causing the original patch to be non-trivially rebased. After rebased, a few bugs in the patch were fixed. The patch was also enhanced it and polling functionality got added. The main changes over the original patch are: dvb_vb2_fill_buffer(): - Set the size of the outgoing buffer after while loop using vb2_set_plane_payload; - Added NULL check for source buffer as per normal convention of demux driver, this is called twice, first time with valid buffer second time with NULL pointer, if its not handled, it will result in crash - Restricted spinlock for only list_* operations dvb_vb2_init(): - Restricted q->io_modes to only VB2_MMAP as its the only supported mode dvb_vb2_release(): - Replaced the && in if condiion with &, because otherwise it was always getting satisfied. dvb_vb2_stream_off(): - Added list_del code for enqueud buffers upon stream off dvb_vb2_poll(): - Added this new function in order to support polling dvb_demux_poll() and dvb_dvr_poll() - dvb_vb2_poll() is now called from these functions - Ported this patch and latest videobuf2 to lower kernel versions and tested auto scan.

media: dvb_frontend: add physical layer scrambling support

2017-12-19T12:08:12Z

This commit adds a new property DTV_SCRAMBLING_SEQUENCE_INDEX. This 18 bit field, when present, carries the index of the DVB-S2 physical layer scrambling sequence as defined in clause 5.5.4 of EN 302 307. There is no explicit signalling method to convey scrambling sequence index to the receiver. If S2 satellite delivery system descriptor is available it can be used to read the scrambling sequence index (EN 300 468 table 41). By default, gold scrambling sequence index 0 is used. The valid scrambling sequence index range is from 0 to 262142. Increase the DVB API version in order userspace to be aware of the changes.

media: frontend: describe nested structs

2017-12-18T14:05:59Z

There are some nested structs on this header, with aren't properly document them. This should solve some warnings after the addition of a patche at kernel-doc adding support for nested structs/unions. Signed-off-by: Mauro Carvalho Chehab
