non-GPL equivalent for irq_of_parse_and_map()

[vadimber]

Hi,

I am trying to map a hardware interrupt to a virtual interrupt in my powerpc device driver for consequent use with request_irq(). A recommended way of doing this is by using the GPL irq_of_parse_and_map() / irq_create_of_mapping() functions. Does anyone know if there is a non-GPL way of doing this?

Thanks,
Vadim

You've come to a place that lives and breathes GPL. Can you say why you want a non-GPL way?

Some of the IRQs are listed in the file "/proc/interrupts" or "/proc/irq" and
Non-GPL applications can get information from the proc files.

It may be possible to add some new proc files to store the irq information retrieved by calling irq_of_parse_and_map() using GPL module and other Non-GPL modules can get the irq information via new proc files.

Could anyone know this is Non-GPL way ?

Thanks,

No, I could know this is GPL way.

Hi greyhairweenie

Thank you for your reply.

How about the way to add a new system call ID for IRQ information and get the information via system call from Non-GPL modules ?

Do you know any other way for some prorietary modules to get the IRQ information ?

Thanks.
