SubjectRe: [PATCH v2 0/2] x86/PCI: SiS PIRQ router updates
Hello Maciej,

Apparently, my previous replies (of 11-sep-2021 to 16-sep-2021) with
some observations somehow went to spam box or whatever. I was going to
retry but got too busy with unrelated stuff at that time. I can re-send
them if necessary.

Anyway. Yes, your patch is very usefull. I've tested it quite thoroughly
back then, including sharing IRQs for 2 unrelated PCI devices etc. I
have it always automatically applied in my private trees since then.

One peculiarity with my specific board is that I had to also patch ROM
BIOS because it included some non-standard $IRT table instead of $PIR
table. With that in place, it now Just Works.

Thank you again for your effort,

Regards,

Nikolai
