The QCOM extended CTI is a heavily parameterized version of ARM’s CSCTI. It allows a debugger to send to trigger events to a processor or to send a trigger event to one or more processors when a trigger event occurs on another processor on the same SoC, or even between SoCs. QCOM extended CTI supports up to 128 triggers. And some of the register offsets are changed. The commands to configure CTI triggers are the same as ARM's CTI.
