This patch fixes a bug which causes all histogram regions to start in the top left corner of the image. The histogram region coordinates are 16 bit values which share a 32 bit register. The bug is due to the region end value assignments overwriting the region start values with zero. Signed-off-by:

The preview engine includes filters that consume columns and lines as part of their operation, thus resulting in a cropped image. To allow turning those filters on/off during streaming without affecting the output image size, the driver adds additional cropping to make the total number of cropped columns and lines constant regardless of which filters are enabled. This process needlessly includes the CFA filter, as whether the filter is enabled only depends on the sink pad format, which can't change during streaming. Exclude the CFA filter from the preview engine margins. Signed-off-by:

Ming Lei reported: IMO, there is a minor fault in the error handling path of uvc_status_start() inside uvc_v4l2_open(), and the 'users' count should have been decreased before usb_autopm_put_interface(). In theory, a [URB resubmission] warning can be triggered when the device is opened just between usb_autopm_put_interface() and atomic_dec(&stream->dev->users). The fix is trivial. Reported-by:

This kind of memcpy() is error-prone. Its replacement with a struct assignment is prefered because it's type-safe and much easier to read. Signed-off-by:

Events for the iMon Knob pad where not correctly interpreted on ARM, resulting in buggy mouse movements (cursor going straight out of the screen), key pad only generating KEY_RIGHT and KEY_DOWN events. A reproducer is: int main(int argc, char ** argv) { char rel_x = 0x00; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__); rel_x = 0x0f; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__); rel_x |= ~0x0f; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__); return 0; } (running on x86 or amd64) $ ./test rel_x:0 @test.c:6 rel_x:15 @test.c:7 rel_x:-1 @test.c:8 (running on armv6) rel_x:0 @test.c:6 rel_x:15 @test.c:7 rel_x:255 @test.c:8 Forcing the rel_x and rel_y variables as signed char fixes the issue.

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: -

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. Reviewed-by:

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.

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. Reviewed-by:

The DVBv3 statistics parameters are limited on several ways: - It doesn't provide any way to indicate the used measure, so userspace need to guess how to calculate/use it; - Only a limited set of stats are supported; - Can't be called in a way to require them to be filled all at once (atomic reads from the hardware), with may cause troubles on interpreting them on userspace; - On some OFDM delivery systems, the carriers can be independently modulated, having different properties. Currently, there's no way to report per-layer stats. To address the above issues, adding a new DVBv5-based stats API. While here, correct inner code nomenclature on a few places. Reviewed-by: -
