Thanks for your prompt reply ... I am using kernel version 2.6.20 ...
OK, that kernel has the irq remapping stuff.
May I know what raw IRQ means ? ? ? and what is the reason I cant map raw_irq_number ???
Sorry, that's not the best terminology. I guess the right name is hardware irq number. You can't map it because the kernel keeps a mapping between hardware irq numbers and virtual irq numbers. request_irq() expects a virtual irq number. cheers -- Michael Ellerman OzLabs, IBM Australia Development Lab wwweb: http://michael.ellerman.id.au phone: +61 2 6212 1183 (tie line 70 21183) We do not inherit the earth from our ancestors, we borrow it from our children. - S.M.A.R.T Person
