From: Smitha T Murthy <smitha.t@samsung.com>
Context bit is set for hardware execution if there is a buffer in source and destination queue before calling try_run in the init_buffers function. Now there will be a new context created and hardware will be invoked for the buffer queued instead of waiting for another buffer to be queued from userspace to set this context bit for hw execution.
