Hello,
From /sys/kernel/debug/tracing I see the following points:
<idle>-0 [000] d.h1 2388.136032: irq_handler_entry: irq=16
name=gp_timer
Is there a simple way to figure out what is the exact final function
called to handle this IRQ?

You have "name=gp_timer", just grep for gp_timer in kernel source.
