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:

All radio tuners in cx88 driver using same address for radio and tuner, so there is no need to probe it twice for same tuner and we can use radio_type UNSET, this also fix broken radio since kernel 2.6.39-rc1 for those tuners. Cc: stable@kernel.org Signed-off-by:

The pwc driver used to: 1. kmalloc a buffer 2. memcpy data to send over usb there 3. do the usb_control_msg call (which does not work with data on the stack) 4. free the buffer For every usb command send. This patch changes the code to instead malloc a buffer for this purpose once and use it everywhere.

Since we always do a set_video_mode on stream start, there is no need to actually send the mode info to the device on a s_fmt / s_parm ioctl. Not doing this saves us doing (slow) usb io. Signed-off-by:

Before this patch various code in the mode setting patch checked pdev->pixfmt, but that was not set until the mode setting succeeded, so it was looking at the old pixfmt! This patch fixes this by making the pixfmt a parameter to set_video_mode, and setting it from set_video_mode on success. Signed-off-by:

The changeset 240ab508 is incomplete, as the first thing that happens at cache clear is to do a memset with 0 to the cache. So, the delivery system needs to be explicitly preserved there. Signed-off-by:

As reported by Lawrence[1], MythTV 0.24.1 does the wrong thing with a DVBv5 call: it fills the delivery system with SYS_UNDEFINED, expecting that the DVB core would work with that. This used to work by accident, as the DVB core were missing the check for the supported delivery systems. Yet, fixing it is easy, so let's add a logic to handle this case, to provide backward compatibility. [1] http://patchwork.linuxtv.org/patch/8314/Signed-off-by:

Some time ago, Manoel sent us a patch adding more stuff to the init sequence. However, his patch were also doing non-related stuff, by changing the init logic without any good reason. So, it was asked for him to submit a patch with just the data that has changed, in order to allow us to better analyze it. As he didn't what it was requested, I finally found some time to dig into his init sequence and add it here. Basically, new stuff is added there. There are a few changes: 1) The removal of the extra (duplicated) logic that puts the chip into the serial mode; 2) Some Viterbi VBER measurement init data was changed from 0x00 to 0xff for layer A, to match what was done for layers B and C. None of those caused any regressions and both make sense on my eyes. The other parameters additions actually increased the tuning quality for some channels. Yet, some channels that were previously discovered with scan disappered, while others appeared instead. This were tested in Brasilia, with an external antena. At the overall, it is now a little better. So, better to add these, and then try to figure out a configuration that would get even better scanning results. Reported-by:
