Determining Linux irq level
 
Is there a means of determining irq level inside a kernel driver? Something like :KeGetCurrentIrql in Windows.
How about in GDB or a crash dump?
Thanks

Linux doesn't use IRQL. You can see here functions related to IRQ handling; https://www.kernel.org/doc/htmldocs/genericirq/

If you just want to view interrupt counts, you can use;
Code:
cat /proc/interrupts
or
Code:
procinfo
