2012-02-15[media] hdpvr: update picture controls to support firmware versions > 0.15Taylor Ralph
Correctly sets the max/min/default values for the hdpvr picture controls. The reason the current values didn't cause a problem until now is because any firmware <= 0.15 didn't support them. The latest firmware releases properly support picture controls and the values in the patch are derived from the windows driver using SniffUSB2.0. Thanks to Devin Heitmueller for helping me.

2012-01-26[media] imon: don't wedge hardware after early callbacksJarod Wilson
This patch is just a minor update to one titled "imon: Input from ffdc device type ignored" from Corinna Vinschen. An earlier patch to prevent an oops when we got early callbacks also has the nasty side-effect of wedging imon hardware, as we don't acknowledge the urb. Rework the check slightly here to bypass processing the packet, as the driver isn't yet fully initialized, but still acknowlege the urb and submit a new rx_urb. Do this for both interfaces -- irrelevant for ffdc hardware, but relevant for newer hardware, though newer hardware doesn't spew the constant stream of data as soon as the hardware is initialized like the older ffdc devices, so they'd be less likely to trigger this anyway... Tested with both an ffdc device and an 0042 device.

2012-01-17[media] dvb_frontend: Don't call get_frontend() if idleMauro Carvalho Chehab
If the frontend is in idle state, don't call get_frontend. Calling get_frontend() when the device is not tuned may result in wrong parameters to be returned to the userspace. I was tempted to not call get_frontend() at all, except inside the dvb frontend thread, but this won't work for all cases. The ISDB-T specs (ABNT NBR 15601 and ARIB STD-B31) allow the broadcaster to dynamically change the channel specs at runtime. That means that an ISDB-T optimized application may want/need to monitor the TMCC tables, decoded at the frontends via get_frontend call. So, let's do the simpler change here. Eventually, the logic could be changed to work only if the device is tuned and has lock, but, even so, the lock is also standard-dependent. For ISDB-T, the right lock to wait is that the demod has TMCC lock. So, drivers may need to implement some logic to detect if the get_frontend info was retrieved or not.

2012-01-16[media] xc4000: add support for signal strength measuresMiroslav Slugen
In xc4000 chipsets real signal and noise level is stored in register 0x0A and 0x0B,so we can use those registers to monitor signal strength. I tested this patch on 2 different cards Leadtek DVR3200 and DTV2000H Plus, both with same results, I used special antenna hubs (toner 4x, 6x, 8x and 12x) with mesured signal lost, both registers are in dB value, first represent signal with limit value -113.5dB (should be -114dB) and exactly match with test results. Second represents noise level also in dB and there is no maximum value, but from tests we can drop everything above 32dB which tuner realy can't use, signal was usable till 20dB noise level. In digital mode we can take signal strength but sadly noise level is not relevant and real value is stored in demodulator for now just zl10353, also digital mode is just for testing, because it needs changing other parts of code which reads data only from demodulator. In analog mode I was able to test only FM radio, signal level is not important, it says something about cable and hub losts, but nothing about real quality of reception, so even if we have signal level at minimum 113dB we can still here radio, because of that it is displaied only in debug mode, but for real signal level is used noise register which is again very accurate, radio noise level was betwen 6-20dB for good signal, 20-25dB for medium signal, and above 25dB signal is unusable. For now real benefit of this patch is only for FM radio mode. Signed-off-by: Miroslav Slugen <thunder.mmm@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
