how to find out IRQ end user
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?

omap2_gp_timer_interrupt() -- Regards Sudip

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