The 10 specification contains generic information about how those configuration 11 elements behave, but not precisely how they apply to particular hardware 12 features. We leave some leeway to drivers to decide how to map selection 13 rectangles to device features, as long as they comply with the V4L2 14 specification. This is needed as hardware features differ between devices, so 15 it's the driver's responsibility to handle this mapping. 16 17 Unfortunately, this lack of clearly defined mapping in the specification has led 18 to different drivers mapping the same hardware features to different API 19 elements, or implementing the API elements with slightly different 20 behaviours. Furthermore, many drivers have implemented selection rectangles in 21 ways that do not comply with the V4L2 specification. All of this makes userspace 22 development difficult. 23 24 Sub-device configuration models specify in detail what the user space can expect 25 from a sub-device in terms of V4L2 sub-device interface support, semantics 26 included. 27 28 A sub-device may implement more than one configuration model at the same 29 time. The implemented configuration models can be obtained from the sub-device's 30 ``V4L2_CID_CONFIG_MODEL`` control. 31 32 .. _media_subdev_config_model_common_raw_sensor: 33 34 Common raw camera sensor model > 35 ------------------------------ 36 -- 0-DAY CI Kernel Test Service https://github.com/intel/lkp-tests/wiki
