Abstract
The described embodiments provide a system for accessing values for configuration space registers (CSRs). This system includes a CSR data storage mechanism with an address input and a CSR data output. The CSR data storage mechanism includes a memory containing a number of memory locations for storing the true or actual values for CSRs for functions for corresponding devices. In these embodiments, the memory locations are divided into at least one shared region and at least one unique region. In these embodiments, in response to receiving an address for a memory location on the address input, the CSR data storage mechanism accesses the value for the CSR in the memory location in a corresponding shared region or unique region.
