Hi, I have a question about the ICU controller in the XO 1.75. I was looking into porting over and extending the FIQ debugger onto the XO (which allows debugging wedged/deadlocked kernels), and was wondering if it was possible to force triggering a particular IRQ (not FIQ).
It's a feature common to SoCs where you have many cores (uncoherent ones at that, such as an AP and a service/power/control core), and my understanding is that the MMP2 SoC is one of these - if I understand correctly, you can route an interrupt to the SP. Is this what the MMP2_ICU_SP_IRQ_SEL/MMP2_ICU_PJ4_IRQ_SEL/MMP2_ICU_PJ4_FIQ_SEL regs are for?
