Appalayagari Sreedhar (INDIA)
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.

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