[coreboot] Re: IRQ routing: how to do the mainboard_picr_data/_intr_data structures?

[Naresh G. Solanki]

Hi Mike,

I see that IRQ routing that you set in Coreboot is different then that in
UEFI bios.
I recommend you first try to match them.
Required data is already available in the dump you took.

Also this link can be of help:
https://gist.github.com/mcastelino/4acda7c2407f1c51e68f3f994d8ffc98

IRQ routing is mandatory for non-MSI capable devices so make sure you best
match them with UEFI bios for now.

There might be some other issues other than IRQ routing but you can focus
on them later as they dont seem critical.

Please let me know how it goes.

Naresh G Solanki
