But this exception is masked by MSR\[EE\] bit, the MSR\[EE\] should be set to 1 in core1 to get this exception. But the NXP E500MCRM.pdf reference manual indicates that MSR\[CE\] is the mask bit for DOORBELL_CRITICAL Exception. +Additional information: +In qemu-8.1.2/target/ppc/excp_helper.c i try to change in ppc_next_unmasked_interrupt_generic function: + +``` +if (FIELD_EX64(env->msr, MSR, CE)) { + /* Critical doorbell */ + if (env->pending_interrupts & PPC_INTERRUPT_CDOORBELL) { <- move this part from (async_deliver != 0) + return PPC_INTERRUPT_CDOORBELL; + } + /* External critical interrupt */ + if (env->pending_interrupts & PPC_INTERRUPT_CEXT) { + return PPC_INTERRUPT_CEXT; + } +} +``` + + +And it seems to work in my case. |
