AR# 51521

The Cortex A9 core0 and core1 cannot be reconfigured. 

 

Per UG585 (Zynq 7000 Technical Reference Manual), certain sources do have Advanced QoS registers that allow changes to the maximum number of outstanding transactions.

 

Function	Name	Overview
TrustZone	security_fssw_s0 security_fssw_s1	Control boot secure settings for the slave ports of the slave interconnect.
Advanced QoS	qos_cntl, max_ot, max_comb_ot, aw_p, aw_b, aw_r, ar_p, ar_b, ar_r	Control advanced QoS features, maximum number of outstanding transactions, AW and AR channel peak rates, burstiness, average rates.

 

 

 

 

However, the only sources that have Advanced QoS registers are the AHB Masters, DMA Controller, and the L2 Cache. 

The CPU is not included as something that is reconfigurable via the QoS registers.
