V4L/DVB (13240): firedtv: fix regression: tuning fails due to bogus error return

2009-11-07T14:55:11+00:00

Since 2.6.32(-rc1), DVB core checks the return value of
dvb_frontend_ops.set_frontend.  Now it becomes apparent that firedtv
always returned a bogus value from its set_frontend method.

V4L/DVB (13237): firedtv: length field corrupt in ca2host if length>127

2009-11-07T14:55:10+00:00

This solves a problem in firedtv that has become major for Swedish DVB-T
users the last month or so.  It will most likely solve issues seen by
other users as well.

If the length of an AVC message is greater than 127, the length field
should be encoded in LV mode instead of V mode. V mode can only be used
if the length is 127 or less. This patch ensures that the CA_PMT
message is always encoded in LV mode so PMT message of greater lengths
can be supported.

V4L/DVB (12582): The current AVC debugging can clog the log down a lot since many

2009-09-12T15:19:38+00:00

applications tend to check the signal strength very often.  This patch
enables users to select which AVC messages to log using a bitmask.  In
addition, it also enables the possibility to debug application PMTs sent
to the driver.  This will be usable since the CA support is still poorly
tested for lots of CAMs and CA systems.

V4L/DVB (12482): firedtv: add PID filtering for SW zigzag retune

2009-09-12T15:19:08+00:00

The AVC protocol uses the same command for tuning and PID filtering and
since dvb-core uses a software zigzagging to do automatic retuning this
could cause all PID filters to be cleared.  PID filter information is
now included in all DSD commands to the card.

Background:

There is a problem in the firedtv driver that causes recordings to stop
if the SW zigzag algorithm in dvb-core kicks in with a retune after the
application has set up the PID filters.  Since tuning and setting PID
filters uses the same AVC command (DSD) and only the replace subfunction
is supported by the card, it is not possible to do a retune without
setting the PID filters.  This means that the PID filtering has to be
sent in each tune.

This problem applies to C and T cards since S and S2 cards tune using a
vendor specific command.  The patch corrects the problem by sending the
PID list in each tune.  I have tested it on my T card with a good
result.

How to trigger problem:  Zap to a channel and output AV to a file, e.g.
"tzap -c channels.conf SVT1 -r -o SVT1.ts".  After a short while, pull
the antenna cable from the card.  The lock on the channel will disappear
and the TS file will stop increasing in size. Wait a couple of seconds.
Replug the cable again.  You will get a lock on the channel again, but
the TS file will never increase in size agains sinze no PIDS are
filtered.

Tested with kaffeine with DVB-T and DVB-C:  Fixes retuning after antenna
was plugged out and back in with DVB-T.  Does not fix this with DVB-C,
but also doesn't regress on DVB-C.

V4L/DVB (11739): remove driver_data direct access of struct device

2009-06-16T21:20:58+00:00

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

V4L/DVB (11724): firedtv: Storage class should be before const qualifier

2009-06-16T21:20:56+00:00

The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.
