Fixes: 9a1a8f9953f ("[media] coda: Add tracing support") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> 2015-04-10T13:12:31+00:00 Philipp Zabel p.zabel@pengutronix.de 2015-01-29T17:36:00+00:00 urn:sha1:9a1a8f9953f3f101ce769878fc7bbbc43a4fd2dc 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 Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Kamil Debski <k.debski@samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
