* @cp: radeon_cp structure holding CP information
*
* We don't need to initialize the lockup tracking information as we will either
* have CP rptr to a different value of jiffies wrap around which will force
* initialization of the lockup tracking informations.
*
* A possible false positivie is if we get call after while and last_cp_rptr ==
* the current CP rptr, even if it's unlikely it might happen. To avoid this
* if the elapsed time since last call is bigger than 2 second than we return
* false and update the tracking information. Due to this the caller must call
* r100_gpu_cp_is_lockup several time in less than 2sec for lockup to be reported
* the fencing code should be cautious about that.
*
* Caller should write to the ring to force CP to do something so we don't get
* false positive when CP is just gived nothing to do.
