sample code in c language,and where could i get the pin diagram for
IMX27,i have searched in the net but i coldnt get the pin diagram.

See /proc/interrupts

for example (on ETRAX based board)

[root@ester /]113# cat /proc/interrupts
 2:       2490 + timer, + gpio poll
 3:          0   fast timer int
 6:          0   ETRAX 100LX built-in ethernet controller
 8:          0 + serial
11:          0 + gpio PA
16:         90   ETRAX 100LX built-in ethernet controller
17:         98   ETRAX 100LX built-in ethernet controller
22:        185 + serial 0 dma tr
23:          0 + serial 0 dma rec

the first column is the IRQ number. If you want to handle an interrupt in
a device driver see "int request_irq(IRQ_Number, ....)" well descrobe in
the book Linux device drivers Chap10. http://lwn.net/Kernel/LDD3 /

Good Luck.

I'm sure the code that handles the interrupt controller (the device) is in
C. There is no need to write it in assembler. Only the interrupt entry and
exit functions are written in assembler.
