Add an enum_fmt format flag to specifically tag coded formats where dynamic resolution switching is supported by the device. This is useful for some codec drivers that can support dynamic resolution switching for one or more of their listed coded formats. It allows userspace to know whether it should extract the video parameters itself, or if it can rely on the device to send V4L2_EVENT_SOURCE_CHANGE when such changes are detected. Signed-off-by:

Add an enum_fmt format flag to specifically tag coded formats where full bytestream parsing is supported by the device. Some stateful decoders are capable of fully parsing a bytestream, but others require that userspace pre-parses the bytestream into frames or fields (see the corresponding pixelformat descriptions for details). If this flag is set, then this pre-parsing step is not required (but still possible, of course). Signed-off-by:

Some decoders use intra slice/frame references. The capture buffer pointed by these references might be new and thus have invalid timestamp which prevents the decoder logic from retrieving the vb2_buffer object based on the output buf timestamp. Copy all metadata (including the timestamp) before starting the decode operation. Suggested-by:

The cedrus VPU is slice-based and expects V4L2_PIX_FMT_H264_SLICE buffers to contain H264 slices with no start code. Expose this to userspace with the newly added menu control. These two controls are specified as mandatory for applications, but we mark them as non-required on the driver side for backwards compatibility. Signed-off-by:

Stateless decoders have different expectations about the start code that is prepended on H264 slices. Add a menu control to express the supported start code types (including no start code). Drivers are allowed to support only one start code type, but they can support both too. Note that this is independent of the H264 decoding mode, which specifies the granularity of the decoding operations. Either in frame-based or slice-based mode, this new control will allow to define the start code expected on H264 slices. Signed-off-by:

Some stateless decoders don't support per-slice decoding granularity (or at least not in a way that would make them efficient or easy to use). Expose a menu to control the supported decoding modes. Drivers are allowed to support only one decoding but they can support both too. To fully specify the decoding operation, we need to introduce a start_byte_offset, to indicate where slices start.

The V4L2_PIX_FMT_H264_SLICE_RAW name was originally suggested because the pixel format would represent H264 slices without any start code. However, as we will now introduce a start code menu control, give the pixel format a more meaningful name, while it's still early enough to do so. Signed-off-by:

Our list_sort() utility has always supported a context argument that is passed through to the comparison routine. Now there's a use case for the similar thing for sort(). This implements sort_r by simply extending the existing sort function in the obvious way. To avoid code duplication, we want to implement sort() in terms of sort_r(). The naive way to do that is static int cmp_wrapper(const void *a, const void *b, const void *ctx) { int (*real_cmp)(const void*, const void*) = ctx; return real_cmp(a, b); } sort(..., cmp) { sort_r(..., cmp_wrapper, cmp) } but this would do two indirect calls for each comparison. Instead, do as is done for the default swap functions - that only adds a cost of a single easily predicted branch to each comparison call. Aside from introducing support for the context argument, this also serves as preparation for patches that will eliminate the indirect comparison calls in common cases.

If reg_r() fails, then gspca_dev->usb_buf was left uninitialized, and some drivers used the contents of that buffer in logic. This caused several syzbot errors: https://syzkaller.appspot.com/bug?extid=397fd082ce5143e2f67d https://syzkaller.appspot.com/bug?extid=1a35278dd0ebfb3a038a https://syzkaller.appspot.com/bug?extid=06ddf1788cfd048c5e82 I analyzed the gspca drivers and zeroed the buffer where needed.

Some users have been having a hard time finding the hidden menus. A typically case are camera sensor drivers (e.g IMX219, OV5645, etc), which are common on embedded platforms and not really "ancillary" devices. The problem with MEDIA_SUBDRV_AUTOSELECT seems to be related to the fact that it uses the "visible" syntax to hide the menus. This is not obvious and it normally takes some time to figure out. To fix the problem, add a comment on each of hidden menus, which should clarify what option is causing menus to be hidden. Signed-off-by:

Not all sensors will be able to guarantee a proper initial state. This may be either because the driver is not properly written, or (probably unlikely) because the hardware won't support it. While the right solution in the former case is to fix the sensor driver, the real world not always allows right solutions, due to lack of available documentation and support on these sensors. Let's relax this requirement, and allow the driver to support stream start, even if the sensor initial sequence wasn't the expected. Also improve the warning message to better explain the problem and provide a hint that the sensor driver needs to be fixed. Signed-off-by:

When the support for serial busses was introduced in V4L2, it was decided to use the existing parallel bus media bus pixel codes to describe them. While this was a practical choice at the time, it necessitates choosing which one of the many parallel mbus pixel codes to use, for on the serial busses these formats are effectively all equivalent. The practice has always been to use the pixel code that describes a bus that transfers a single sample per clock. Document this. Signed-off-by:

This is mostly a port of Jacopo's fix: commit aa4bb8b8 Author: Jacopo Mondi <jacopo@jmondi.org> Date: Fri Jul 6 05:51:52 2018 -0400 media: ov5640: Re-work MIPI startup sequence In the OV5645 case, the changes are: - At set_power(1) time power up MIPI Tx/Rx and set data and clock lanes in LP11 during 'sleep' and 'idle' with MIPI clock in non-continuous mode. - At set_power(0) time power down MIPI Tx/Rx (in addition to the current power down of regulators and clock gating). - At s_stream time enable/disable the MIPI interface output. With this commit the sensor is able to enter LP-11 mode during power up, as expected by some CSI-2 controllers. Many thanks to Fabio Estevam for his help debugging this issue. Tested-by:
