ABSTRACT:
The disclosed embodiments relate to a secure configuration space for a computing device. Each of the configuration resisters in a configuration space are divided into security bits and configuration data bits. The security bits are assigned a predetermined value. When reading from or writing to a given configuration register, the data in the bit positions corresponding to security bits must match the predetermined values or read/write access is denied.
