Abstract
Systems, methods, and apparatuses for platform security are described. For example, in an embodiment, an apparatus includes address translation circuitry to translation a virtual address to a physical address and to provide a first protection domain, at least one protection range register, the at least one protection range register to store a range of virtual addresses to protect as part of a protection domain, and comparison circuitry to compare the virtual address to the range of virtual addresses of the at least one protection range register and to output a second protection domain upon a match in of the virtual address and the range of virtual addresses of the at least one protection register.
Claims20
An apparatus comprising:
- address translation circuitry to translation a virtual address to a physical address and to provide a first protection domain;
- at least one protection range register, the at least one protection range register to store a range of virtual addresses to protect as part of a protection domain;
- comparison circuitry to compare the virtual address to the range of virtual addresses of the at least one protection range register and to output a second protection domain upon a match in of the virtual address and the range of virtual addresses of the at least one protection register;
- and
- a selector circuit to select between the first and second protection domain.
A method comprising:
- receiving a virtual address at address translation circuitry to translation the virtual address to a physical address and to provide a first protection domain;
- comparing the virtual address to a range of virtual addresses of at least one protection range register and to output a second protection domain upon a match in of the virtual address and the range of virtual addresses of the at least one protection register;
- and
- selecting between the first and second protection domain.
