I/O Port Permissions

[..]if the program has permission to access a port, a "0" is stored at the corresponding bit index, and if the program does not have permission, a "1" is stored there.[...]If the bit in the I/O port permissions bitmap is set, the program is allowed access to this port, and the instruction is allowed to execute. If the bit is clear, the program does not have access and the processor generates a General Protection Fault.[...]
