I'm into the atombios and I wonder about ports.
"AMD(ATI) port" is direct or indirect MMIO. Is modern atombios bytecode (from evergreen) still use indirect access? Because to access the PLLs and MC there are opcode argument types which would obsolete the indirect MMIO, wouldn't they?
The current interpreter does ignore the "PCI port" and "SYSIO port", is this safe for a OS driver to ignore them?
