To summarize: -- The system keeps no information about which task/TCB scheduled an SRB (if indeed the scheduling was even done by a task). -- Individual schedulers of SRBs can pass whatever information they want (such as a TCB address) via parameter to the target SRB routine -- the PTCBADDR parameter of IEAMSCHD can be used to identify any task (this is used for PURGEDQ and also for SRB to task percolation if the SRB fails). There is no programming interface provided to extract that data.
