Subject: [Qemu-devel] Debugging IRQ latency
Date: Fri, 21 May 2004 22:35:35 +0200 [thread overview]
Message-ID: <87vfip5xig.fsf@Janik.cz> (raw)
Hi,
hw/i8259.c contains (when DEBUG_ is turned on):
(double)(cpu_get_ticks() - irq_time[irq]) * 1000000.0 / ticks_per_sec);
but cpu_get_ticks is defined as static in vl.c:
static inline int64_t cpu_get_ticks(void)
Thus you can't debug IRQ latency.
