This is a first try at a program to grok lxirqs.
Sanity check first, I'm not signing this off yet. Are the enable and invert tests correct below?
Long term goal is a program that will follow the IRQ through the magic rabbit hole and up to the CPU. I don't know how to do vr reads in user mode, however.
What do you mean with VR? MSRs? If so, we have code in flashrom you can copy (it's basically opening /dev/msr as file, then seeking to the desired MSR, followed by read/write). Pleas be aware that you need to modprobe msr before using /dev/msr.
Here's the current output on alix1c, which is strange looking to me. IRQ A, GPIO pin 0 Input Enabled and Not Inverted IRQ B, GPIO pin 7 Input Enabled and Inverted IRQ C, GPIO pin 12 Input Enabled and Inverted IRQ D, GPIO pin 13 Input Disabled and Not Inverted
