    SubjectRe: [linux-usb-devel] who I do know if a interrupt is ioapic_edge_type or ioapic_level_type? [Was Re: [Fwd: Re: [Linux-usb-users] Fwd: Re: 2.6.17-rc6-mm2 - USB issues]]

    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.
