[media] ivtv: Fix radio support

2011-11-03T09:42:15+00:00

Although the ivtv driver reports radio support through the V4L2 API, it fails
to actually enable it. This patch fixes that.

[media] ivtv: fill in service_set

2011-09-06T17:51:27+00:00

The service_set field of struct v4l2_sliced_vbi_cap was never filled in.
The v4l2-compliance tool complained about this, so this is now fixed.

[media] drivers/media: do not use EXTRA_CFLAGS

2011-09-03T21:50:59+00:00

Usage of these flags has been deprecated for nearly 4 years by:

    commit f77bf01425b11947eeb3b5b54685212c302741b8
    Author: Sam Ravnborg 
    Date:   Mon Oct 15 22:25:06 2007 +0200

        kbuild: introduce ccflags-y, asflags-y and ldflags-y

Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command
line use. By default, gmake(1) do not override command line setting, so this is
likely to result in build failure or unexpected behavior.

Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

[media] v4l2-event/ctrls/fh: allocate events per fh and per type instead of just per-fh

2011-07-27T20:53:31+00:00

The driver had to decide how many events to allocate when the v4l2_fh struct
was created. It was possible to add more events afterwards, but there was no
way to ensure that you wouldn't miss important events if the event queue
would fill up for that filehandle.

In addition, once there were no more free events, any new events were simply
dropped on the floor.

For the control event in particular this made life very difficult since
control status/value changes could just be missed if the number of allocated
events and the speed at which the application read events was too low to keep
up with the number of generated events. The application would have no idea
what the latest state was for a control since it could have missed the latest
control change.

So this patch makes some major changes in how events are allocated. Instead
of allocating events per-filehandle they are now allocated when subscribing an
event. So for that particular event type N events (determined by the driver)
are allocated. Those events are reserved for that particular event type.
This ensures that you will not miss events for a particular type altogether.

In addition, if there are N events in use and a new event is raised, then
the oldest event is dropped and the new one is added. So the latest event
is always available.

This can be further improved by adding the ability to merge the state of
two events together, ensuring that no data is lost at all. This will be
added in the next patch.

This also makes it possible to allow the user to determine the number of
events that will be allocated. This is not implemented at the moment, but
would be trivial.

[media] v4l2-events/fh: merge v4l2_events into v4l2_fh

2011-07-27T20:53:31+00:00

Drivers that supported events used to be rare, but now that controls can also
raise events this will become much more common since almost all drivers have
controls.

This means that keeping struct v4l2_events as a separate struct make no more
sense. Merging it into struct v4l2_fh simplifies things substantially as it
is now an integral part of the filehandle struct.

[media] ivtv,cx18: Use default version control for VIDIOC_QUERYCAP

2011-07-27T20:53:14+00:00

After discussing with Andy Walls on irc, we've agreed that this
is the best thing to do. No regressions will be introduced, as 3.x.y
is greater then the current versions for cx18 and ivtv.

[media] cx18/ivtv: fix g_tuner support

The driver shouldn't override vt->type, and the tuner name should be
based on vt->type as well.

Internally separates the setting of the broadcast standard for the encoder &
decoder. Externally there's no change in functionality.
