I'm in the process of updating isapnptools, and just got rid of all references to ioperm because iopl is needed anyway on x86 systems and gives unrestricted port access.
I have some alpha patches, which don't use iopl, but just use ioperm, so the question is, how do IO permissions work on Alpha ? (More specifically, does iopl exist and do the same thing for alpha systems as x86).
Grepping the kernel sources shows nothing for ioperm or iopl for alpha systems, so I guess it's a C library thing. Would someone please tell me how IO works on Alpha systems, or point me in the right direction.
