We are using ArmV8 64 in our project. would like to know the answers for the below question ?
Question 1 :
I couldn't figure out, what the above code does ?
Question 2 : When a user space app is interrupted, how the el1h_irq_handler is invoked () ?
Could you give a step by step info, or documented anywhere ?
Question 3 : Does ARM ABI plays a role in transition from user space to kernel space ?
Hi Prasath,
