Sure:

name: kvm_exit
ID: 472
format:
	field:unsigned short common_type;	offset:0;	size:2;	signed:0;
	field:unsigned char common_flags;	offset:2;	size:1;	signed:0;
	field:unsigned char common_preempt_count;	offset:3;	size:1;	signed:0;
	field:int common_pid;	offset:4;	size:4;	signed:1;

	field:unsigned long pc;	offset:8;	size:4;	signed:0;
	field:unsigned int reason;	offset:12;	size:4;	signed:0;

print fmt: "[%s]PC: 0x%08lx", __print_symbolic(REC->reason, { 0, "Interrupt" }, { 1, "TLB Mod" }, { 2, "TLB Miss (LD)" }, { 3, "TLB Miss (ST)" }, { 4, "Address Error (LD)" }, { 5, "Address Err (ST)" }, { 8, "System Call" }, { 9, "Break Inst" }, { 10, "Reserved Inst" }, { 11, "COP0/1 Unusable" }, { 13, "Trap Inst" }, { 14, "MSA FPE" }, { 15, "FPE" }, { 21, "MSA Disabled" }, { 32, "WAIT" }, { 33, "CACHE" }, { 34, "Signal" }), REC->pc
