| | | | | | | | | Besides the usual inconsistencies in input enumeration there was also a kernel crash if you tried to poll on a vbi node.

* [media] saa7146: fix querycap, vbi/video separation and g/s_registerHans Verkuil2012-05-142-6/+37
| | | | | | | | | | | | | | The querycap ioctl returned an incorrect version number and incorrect capabilities (mixing up vbi and video caps). The reason for that was that video nodes could do vbi activities: that should be separated between the vbi and video nodes. There were also a few minor problems with dbg_g/s_register that have been resolved. The mxb/saa7146 driver now passes the v4l2_compliance tests.

* [media] v4l2-dev: add flag to have the core lock all file operationsHans Verkuil2012-05-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This used to be the default if the lock pointer was set, but now that lock is by default only used for ioctl serialization. Those drivers that already used core locking have this flag set explicitly, except for some drivers where it was obvious that there was no need to serialize any file operations other than ioctl. The drivers that didn't need this flag were: drivers/media/radio/dsbr100.c drivers/media/radio/radio-isa.c drivers/media/radio/radio-keene.c drivers/media/radio/radio-miropcm20.c drivers/media/radio/radio-mr800.c drivers/media/radio/radio-tea5764.c drivers/media/radio/radio-timb.c drivers/media/video/vivi.c sound/i2c/other/tea575x-tuner.c The other drivers that use core locking and where it was not immediately obvious that this flag wasn't needed were changed so that the flag is set together with a comment that that driver needs work to avoid having to set that flag. This will often involve taking the core lock in the fops themselves. Eventually this flag should go and it should not be used in new drivers. There are a few reasons why we want to avoid core locking of non-ioctl fops: in the case of mmap this can lead to a deadlock in rare situations since when mmap is called the mmap_sem is held and it is possible for other parts of the code to take that lock as well (copy_from_user()/copy_to_user() perform a down_read(&mm->mmap_sem) when a page fault occurs). It is very unlikely that that happens since the core lock serializes all fops, but the kernel warns about it if lock validation is turned on. For poll it is also undesirable to take the core lock as that can introduce increased latency. The same is true for read/write. While it was possible to make flags or something to turn on/off taking the core lock for each file operation, in practice it is much simpler to just not take it at all except for ioctl and leave it to the driver to take the lock. There are only a handful fops compared to the zillion ioctls we have. I also wanted to make it obvious which drivers still take the lock for all fops, so that's why I chose to have drivers set it explicitly.

* [media] xc4000: add support for signal strength measuresMiroslav Slugen2012-01-161-0/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* [media] xc3028: fix center frequency calculation for DTV78 firmwareGianluca Gennari2012-01-061-10/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the previous one proposed in the thread "xc3028: force reload of DTV7 firmware in VHF band with Zarlink demodulator", at the linux-media@vger.kernel.org ML. The problem is that the firmware DTV78 works fine in UHF band (8 MHz bandwidth) but is not working at all in VHF band (7 MHz bandwidth). Reading the comments inside the code, I figured out that the real problem could be connected to the formula used to calculate the center frequency offset in VHF band. In fact, removing this adjustment fixes the problem: if ((priv->cur_fw.type & DTV78) && freq < 470000000) offset -= 500000; This is coherent to what was implemented for the DTV7 firmware by an Australian user: if (priv->cur_fw.type & DTV7) offset += 500000; In the end, now the center frequency is the same for all firmwares (DTV7, DTV8, DTV78) and doesn't depend on channel bandwidth. The final code looks clean and simple, and there is no need for any "magic" adjustment: if (priv->cur_fw.type & DTV6) offset = 1750000; else /* DTV7 or DTV8 or DTV78 */ offset = 2750000; Signed-off-by: Gianluca Gennari <gennarone@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
