Here is an example: Call Trace: [<ffffffff8006b2b0>] default_idle+0x29 <-- ffffffff803ddf90: [<ffffffff80048d19>] cpu_idle+0x95 ffffffff803ddfa0: [<ffffffff803e7801>] start_kernel+0x220 ffffffff803ddfc0: [<ffffffff803e722f>] x86_64_start_kernel+0x22f and Stack Trace: * [<ffffffff8006b2b0>] default_idle+0x29 <-- ffffffff803ddf90: [<ffffffff80048d19>] cpu_idle+0x95 ffffffff803ddf98: 0000000000200800 ffffffff803ddfa0: [<ffffffff803e7801>] start_kernel+0x220 ffffffff803ddfa8: 0000000000086800 ffffffff803ddfb0: 0000000000000000 ffffffff803ddfb8: ffffffff80430720 ffffffff803ddfc0: [<ffffffff803e722f>] x86_64_start_kernel+0x22f ffffffff803ddfc8: 80008e000010019c ffffffff803ddfd0: 00000000ffffffff ffffffff803ddfd8: 0000000000000000 ffffffff803ddfe0: 0000000000000000 ffffffff803ddfe8: 0000000000200000 ffffffff803ddff0: 0000000000000000 ffffffff803ddff8: 0000000000000000 Signed-off-by: Don Slutz <Don@xxxxxxxxxxxxxxx> Acked-by: Ian Campbell <ian.campbell@xxxxxxxxxx> --- tools/xentrace/xenctx.c | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) diff --git a/tools/xentrace/xenctx.c b/tools/xentrace/xenctx.c index add0058..2207171 100644 --- a/tools/xentrace/xenctx.c +++ b/tools/xentrace/xenctx.c @@ -665,6 +665,12 @@ static int print_code(vcpu_guest_context_any_t *ctx, int vcpu) return 0; } +static void print_stack_addr(guest_word_t addr, int width) +{ + print_stack_word(addr, width); + printf(": "); +} + static int print_stack(vcpu_guest_context_any_t *ctx, int vcpu, int width) { guest_word_t stack = stack_pointer(ctx); @@ -741,7 +747,7 @@ static int print_stack(vcpu_guest_context_any_t *ctx, int vcpu, int width) printf("Stack Trace:\n"); else printf("Call Trace:\n"); - printf("%c [<", xenctx.stack_trace ?
