When transmitting a message and waiting for a reply it would be good to know the time between when the message was transmitted and when the reply arrived. With only one timestamp field it was set to when the reply arrived and the original transmit time was overwritten. Just taking the timestamp in userspace right before CEC_TRANSMIT is called is not reliable, since the actual transmit can be delayed if the CEC bus is busy. Only the driver can fill this in accurately. So split up the ts field into an rx_ts and a tx_ts. Also move the status fields to after the 'reply' field: they were placed in a strange position and make much more sense when grouped with the other status-related fields. This patch also makes sure that the timestamp is taken as soon as possible. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

|
|
* @sequence: The framework assigns a sequence number to messages that are

* If reply is zero upon return and status has the
|

|
|
* the received feature abort message.
|
|
* If reply is zero upon return and status has the

|
* CEC_TX_STATUS_MAX_RETRIES bit set, then no reply was seen at
|
|
* all. If reply is non-zero for CEC_TRANSMIT and the message is a

|
|
* if reply is non-zero, then timeout is set to 1000 (the required
