| H A D | media-request-ioc-queue.rst | 13 MEDIA_REQUEST_IOC_QUEUE - Queue a request
31 If the media device supports :ref:`requests <media-request-api>`, then
32 this request ioctl can be used to queue a previously allocated request.
34 If the request was successfully queued, then the file descriptor can be
35 :ref:`polled <request-func-poll>` to wait for the request to complete.
37 If the request was already queued before, then ``EBUSY`` is returned.
38 Other errors can be returned if the contents of the request contained
40 common error codes. On error both the request and driver state are unchanged.
42 Once a request is queued, then the driver is required to gracefully handle
43 errors that occur when the request is applied to the hardware. The

37 subsystem-specific APIs to support request usage. At the Media Controller
39 node. Their life cycle is then managed through the request file descriptors in
42 request support, such as V4L2 APIs that take an explicit ``request_fd``
50 request. Typically, several such requests will be allocated.
55 Standard V4L2 ioctls can then receive a request file descriptor to express the
56 fact that the ioctl is part of said request, and is not to be applied
59 instead of being immediately applied, and buffers queued to a request do not
60 enter the regular buffer queue until the request itself is queued.
