[Qemu-devel] Hardware interrupts

[Alessandro Corradi]

Hi all,

In http://fabrice.bellard.free.fr/qemu/qemu-tech.html:

"In order to be faster, QEMU does not check at every basic block if an hardware interrupt is pending. Instead, the user must asynchrously call a specific function to tell that an interrupt is pending. This function resets the chaining of the currently executing basic block. It ensures that the execution will return soon in the main loop of the CPU emulator. Then the main loop can test if the interrupt is pending and handle it."

What means "the user  must asynchrously
call a specific function..."?

In which sense "user must"?

Which "Specific function"?

How QEMU checks for hardware interrups?

Thanks
