And the waiting queue wakeup, precisely in the interruption, also is a frame of data written to buffer[0]. To illustrate the API2.

In fact, according to the function of the execution process, the function should be preceded by the interrupt function, the function of the stream list to get the current access to the current cache area is understood as buffer[0]. My heart is Android4. More than 3 blog posts for their own reading Linux under the V4L2 video driver under the framework of the source, all for their own summary.
