XU control information is supposed to be entirely discoverable using standard UVC queries. As some devices report bogus information (such as reporting a read-only control as being read-write), add a fixup table for XU controls. This table can also be used to selectively disable requests supposed to be supported by all XU controls (GET_MIN, GET_MAX, GET_DEF, GET_RES) but not correctly (or at all) supported by the device. The table currently disables GET_CUR on the Logitech motor control XU pan/tilt controls. Signed-off-by:

XU controls initialization requires querying the device for control information. As some buggy UVC devices will crash when queried repeatedly in a tight loop, delay XU controls initialization until first use. Signed-off-by:

Now that control information structures are not shared between control instances, embed a uvc_control_info instance inside the uvc_control structure instead of storing a pointer. Signed-off-by:

This patch removes the sysadmin requirements for UVCIOC_CTRL_MAP (and the stub implementation of UVCIOC_CTRL_ADD). This requirement no longer makes sense with the new XU control access mechanisms since XU controls can be accessed without adding control mappings first. A maximum number (currently 1024) of control mappings per device is enforced to avoid excess memory consumption caused by careless user space applications. Signed-off-by:

Devices advertise XU controls using a bitmask, in which each bit corresponds to a control. The control selector, used to query the control, isn't available in the USB descriptors. All known UVC devices use control selectors equal to the control bit index plus one. Hardcode that relationship in the driver, making the UVCIOC_CTRL_ADD ioctl obsolete. All necessary information about XU controls can be obtained by the driver at enumeration time. The UVCIOC_CTRL_ADD ioctl is still supported for compatibility reasons, but now always returns -EEXIST. Finally, control mappings are now on a per-device basis and no longer global. As this changes the userspace interface, bump the driver version number to 1.0.0 (it was about time). Signed-off-by:

Increase the sequence number of the v4l2_buffer structure regardless of any buffer states, so that discontinuous sequence numbers allow applications to detect lost video frames. Signed-off-by:

The bandwidth estimate computed with the FIX_BANDIWDTH quirk is too low for many cameras. Don't use maximum packet sizes lower than 1024 bytes to try and work around the problem. According to measurements done on two different camera models, the value is high enough to get most resolutions working while not preventing two simultaneous VGA streams at 15 fps. Signed-off-by:

Don't hold the lock before unregistering the device, since when the device is unregistered the datastruct containing the lock may be freed (if the refcount went to 0). Also fixed the framework documentation that erroneously suggested the wrong locking order as well. Reported-by:

The AVerTV Red HD+ (A850T) is basically the same as the existing AVerTV Volar Black HD (A850), but is specific to the french market. The A850T identifies itself as a A850, but has its own PID. It even suffers from the same EEPROM deficiencies. This is based off a collection of information gathered from the french support forums for Ubuntu, which I tried to properly format into this patch: http://forum.ubuntu-fr.org/viewtopic.php?pid=3322825Signed-off-by:

Mauro Carvalho Chehab authored
Instead of doing its own lock, use core-assisted one. As a bonus, it will do the proper unlock during queue wait events. This fixes a long-standing bug where softwares like tvtime would hang if you try to use cx231xx-alsa. Signed-off-by:
