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

2018-02-23T10:28:41+00:00

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.

media: lirc: lirc mode ioctls deal with current mode

2018-01-23T12:25:26+00:00

The ioctl change the current mode or return the current mode; they
do not tell you which modes are possible (use the lirc features
ioctl for that).

media: lirc: lirc daemon fails to detect raw IR device

2018-01-23T12:24:01+00:00

Since commit 9b6192589be7 ("media: lirc: implement scancode sending"),
and commit de142c324106 ("media: lirc: implement reading scancode")
the lirc features ioctl for raw IR devices advertises two modes for
sending and receiving.

The lirc daemon now fails to detect a raw IR device, both for transmit
and receive.

To fix this, do not advertise the scancode mode in the lirc features
for raw IR devices (however do keep it for scancode devices). The mode
can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

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

2017-12-28T16:17:31+00:00

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.

media: dvb uAPI docs: document mmap-related ioctls

2017-12-28T16:17:30+00:00

5 new ioctls were added to the DVB demux API, in order to
handle memory maped I/O. Add documentation for them.

media: dvb uAPI docs: document demux mmap/munmap syscalls

2017-12-28T16:17:30+00:00

With the new dmx mmap interface, those two syscalls are now
handled by the subsystem. Document them.

This patch is based on the V4L2 text for those ioctls.

media: dvb_frontend: add physical layer scrambling support

2017-12-19T12:08:12+00:00

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.
