About S2C24xx Interrupt Controller

["Qiang Wang" <rurality.linux@xxxxxxxxx>]

hello,everyone

I met a question about the S3C2410/2440 Interrupt Controller.
As we know, it is not a VIC type.So we must judge the interrupt source,and
process it.
My question is that can Linux for s3c24xx take a nest interrupt process.

For example
Timer0 Priority > LCD Priority > UART0 Priority

So when enter the LCD interrupt routine, If change the arm core,to allow a
new interrupt,
and then uart0 interrupt comes,
Will the LCD interrupt service routine be broken,and enter into uart0
interrupt routine?

Timer0 came as the same question.

thanks very much.

best regards,
wangqiang
