This isn't quite the same as "how to handle the VIA quirks correctly", but it does seem like the IRQ API should probably have a call to get the IRQ trigger mode, just like it has ways to set it. I've seen drivers that need to try multiple trigger modes before they find one that will work on the target platform. The actual details of _how_ that trigger mode is set -- APIC, PIC and so on for x86; or other IRQ controllers on other hardware -- should not matter to drivers, since they're platform-specific. The quirk handling code is platform-specific though, and might care. - Dave - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
