Currently, printtrap just prints srr1, which contains part of the MSR prior to the exception. I find useful to dump the current value of the MSR, since it changes when there is an interruption. With this patch, this is the new printtrap model: handled user trap: exception = 0x700 (program) srr0 = 0x100008a0 (0x100008a0) srr1 = 0x800000000002f032 current msr = 0x8000000000009032 lr = 0x1000089c (0x1000089c) curthread = 0x7a50000 pid = 714, comm = ttrap2 Submitted by: Breno Leitao Reviewed by: nwhitehorn Differential Revision: https://reviews.freebsd.org/D14600 Modified: head/sys/powerpc/powerpc/trap.c Modified: head/sys/powerpc/powerpc/trap.c ============================================================================== --- head/sys/powerpc/powerpc/trap.c Sun Apr 8 16:54:07 2018 (r332288) +++ head/sys/powerpc/powerpc/trap.c Sun Apr 8 16:55:28 2018 (r332289) @@ -507,6 +507,7 @@ printtrap(u_int vector, struct trapframe *frame, int i printf(" srr0 = 0x%" PRIxPTR " (0x%" PRIxPTR ")\n", frame->srr0, frame->srr0 - (register_t)(__startkernel - KERNBASE)); printf(" srr1 = 0x%lx\n", (u_long)frame->srr1); + printf(" current msr = 0x%" PRIxPTR "\n", mfmsr()); printf(" lr = 0x%" PRIxPTR " (0x%" PRIxPTR ")\n", frame->lr, frame->lr - (register_t)(__startkernel - KERNBASE)); printf(" curthread = %p\n", curthread);
