    [media] coda: Add tracing support · 9a1a8f99
    Philipp Zabel authored
    This patch adds tracepoints to the coda driver that can be used together
    with the v4l2:v4l2_qbuf and v4l2:v4l2_dqbuf tracepoints to to follow video
    frames through the mem2mem device.
    
    For encoding with the BIT processor:
        coda:coda_enc_pic_run
        coda:coda_enc_pic_done
    
    For decoding with the BIT processor:
        coda:coda_bit_queue
        coda:coda_dec_pic_run
        coda:coda_dec_pic_done
        coda:coda_dec_rot_done
    
    Additionally, two low level tracepoints register whenever the BIT processor
    is started and returns:
        coda:coda_bit_run
        coda:coda_bit_done
