2013-01-24[media] stv090x: On STV0903 do not set registers of the second pathAndreas Regel
Sometimes there is a problem when trying to access the non-existing registers of the second demodulator path on the STV0903. This change removes the calls in case the driver is used on a STV0903.

2013-01-24[media] mb86a20s: remove global BER/PER counters if per-layer counters vanishMauro Carvalho Chehab
If, for any reason, all per-layers counters stop, remove the corresponding global counter. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-01-24[media] mb86a20s: fix the PER reset logicMauro Carvalho Chehab
The logic that resets the device is wrong. It should be resetting just the layer that got read. Also, stop is needed before updating the counters. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-01-24[media] mb86a20s: some fixes at preBER logicMauro Carvalho Chehab
The logic that resets the device is wrong. It should be resetting just the layer that got read. Also, stop is needed before updating the counters. While there, rename it, as we'll soon introduce a postBER logic there. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-01-23[media] dvb_frontend: print a msg if a property doesn't existMauro Carvalho Chehab
If userspace calls a property that doesn't exist, it currently just returns -EINVAL. However, this is more likely a problem at the userspace application, calling it with a non-existing property. So, add a debug message to help tracking it. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-01-23[media] mb86a20s: add CNR measurementMauro Carvalho Chehab
Add Signal/Noise ratio measurement. On this device, a global measure is taken by the demod. It also provides per-layer CNR measurements, based on Modulation Error measures (MER). Reviewed-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-01-23[media] mb86a20s: add BER measurementMauro Carvalho Chehab
Add the methods to read bit error/bit count measurements from mb86a20s. On ISDB-T devices, those reads are done per layer. However, as userspace applications may not be aware of that, add a global measure that will sum the bit errors and bit counts for each layer, storing them into a global value.

2013-01-23[media] mb86a20s: calculate statistics at .read_status()Mauro Carvalho Chehab
Instead of providing separate callbacks to read the several FE stats properties, the better seems to use just one method that will: - Read lock status; - Read signal strength; - if locked, get TMCC data; - if locked, get DVB statistics. As the DVB frontend thread will call this read_status callback on every 3 seconds, and userspace can even call it earlier, all stats data and layers layout will be updated together if available, with is a good thing.

2013-01-23[media] dvb: the core logic to handle the DVBv5 QoS propertiesMauro Carvalho Chehab
Add the logic to poll, reset counters and report the QoS stats to the end user. The idea is that the core will periodically poll the frontend for the stats. The frontend may return -EBUSY, if the previous collect didn't finish, or it may fill the cached data. The value returned to the end user is always the cached data.

2013-01-06[media] omap_vout: find_vma() needs ->mmap_sem heldAl Viro
Walking rbtree while it's modified is a Bad Idea(tm); besides, the result of find_vma() can be freed just as it's getting returned to caller. Fortunately, it's easy to fix - just take ->mmap_sem a bit earlier (and don't bother with find_vma() at all if virtp >= PAGE_OFFSET - in that case we don't even look at its result). While we are at it, what prevents VIDIOC_PREPARE_BUF calling v4l_prepare_buf() -> (e.g) vb2_ioctl_prepare_buf() -> vb2_prepare_buf() -> __buf_prepare() -> __qbuf_userptr() -> vb2_vmalloc_get_userptr() -> find_vma(), AFAICS without having taken ->mmap_sem anywhere in process? The code flow is bloody convoluted and depends on a bunch of things done by initialization, so I certainly might've missed something...

2013-01-06[media] dib0700: do not lock interruptible on tear-down pathsJiri Slaby
When mutex_lock_interruptible is used on paths where a signal can be pending, the device is not closed properly and cannot be reused. This usually happens when you start tzap for example and send it a TERM signal. The signal is pending while tear-down routines are called. Hence streaming is not properly stopped in that case. And the device stops working from that moment on. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
