Subject: RE: Question: GPIO driver how to get irq_base

Hi Grant, Lars-Peter Clausen

Thank you for your information.

It seems nothing driver uses irq_alloc_descs.
Thus, let me clarify my using.

int irq_base = irq_alloc_descs(-1, 0, 12, GFP_KERNEL)
(Intel-ET20T-PCH has GPIO~GPIO11)

Using the above, I can see "irq_base = 18d".
Is the above TRUE ?

Thanks,
