2008-08-21 13:57:47     Interrupts priority

Hi,

 

I have some general query about the interrupts.

 

Nesting is enabled by default in uClinux kernel?

 

in my working system requires three interrupts, request_irq gives the irq number of the each interrupt, suppose if i get the irq numbers as

 

18,19,20 whether these interrupts will be pre-emptive?

 

18-highest and 20-lowest priority.

 

Its a general question please clarify me on this.

 

Best Regards,Sreedhar.

the number has no relation to priority ... the only priority you have control over is the list in the kernel configuration menu
