Can Cross Trigger Configure Multiple Cores to Halt Simultaneously in Self-Hosted Debug?

Dujiao Zhang

In self-hosted debug scenarios, is it feasible to configure the cross-trigger pathway (via CTI/CTM) to halt multiple cores simultaneously? Our experimental results on ARMv9 show that configuring CTI triggers can indeed force cores to stop execution. However, we are uncertain whether this state qualifies as a "halt" (i.e., cores entering debug state), because: According to protocol specifications, self-hosted debug operates through debug exceptions (e.g., breakpoints triggering software handlers), without requiring cores to enter a hardware-controlled debug state.
