Configurable Memory Provisioning

A method, comprising:

• receiving, at a memory interface circuit of a computer system, a memory access request to a memory subsystem that is organized in a hierarchy having at least first and second dimensions, the memory access request including a physical memory address;
• routing, by the memory interface circuit based on provisioning information accessible to the memory interface circuit, the memory access request to a particular provisioning circuit of a plurality of provisioning circuits within the memory interface circuit that are configured to perform different provisioning operations that cause portions of the memory subsystem to be unused, including a first provisioning operation that causes portions of the first dimension to be unused;
• and
• outputting, by the memory interface circuit based on the physical memory address, a set of selection signals from the particular provisioning circuit that are usable to access some, but not all, elements in the first dimension of the memory subsystem.

A computer system, comprising:

• a set of circuit resources arranged according to a hierarchy that includes a plurality of dimensions including a first dimension with m routing options and a second dimension with n routing options;
• and
• a resource interface circuit with a plurality of provisioning circuits that include:
• a first provisioning circuit configured to perform a first provisioning operation that excludes access to a first portion of the set of circuit resources;
• a second provisioning circuit configured to perform a second provisioning operation that excludes access to a second portion of the set of circuit resources;
• wherein the resource interface circuit is configured to:
• receive a request to access the set of circuit resources;
• route, based on provisioning information received by the resource interface circuit, the request to a particular provisioning circuit of the plurality of provisioning circuits;
• and
• output, from the particular provisioning circuit, a set of selection signals that are usable to access some, but not all, elements in one of the plurality of dimensions in order to fulfill the request.
