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. For Qualcomm extended CTI, it supports up to 128 triggers.
