    SubjectRe: PCI Express support for 2.4 kernel


    This really isn't appropriate. The

    With PCI-E, config space accessed through memory. Each device gets
    its own 4k memory mapped config, total 256M for all devices.

    thing _really_ does not work on x86, since 256M of IO mapping is _way_ way
    too much.

    You _really_ need to allocate a FIXMAP entry (just one), and then use

    set_fixmap_nocache(FIX_PCIEXPRESS, phys);

    to set it up for each device.

    That's actually going to be a lot simpler than what you do now.
