    SubjectRe: /proc/pci design idea

    I've heard several suggestions involving adding another system call.

    I think these are decent ideas, but I would prefer not going around and
    creating system calls willy-nilly. Entries in /proc use existing system
    calls, and also take care of managing permissions, security restrictions,
    etc. (The pciconfig_write system call on alphas can be executed by anyone,
    for example.)

    Only problem is, it requires /proc to be configured in. Oh well, I'm not
    the first and won't be the last.
