Abstract: A method and apparatus for enhancing/extending a serial point-to-point interconnect architecture, such as Peripheral Component Interconnect Express (PCIe) is herein described. Temporal and locality caching hints and prefetching hints are provided to improve system wide caching and prefetching. Message codes for atomic operations to arbitrate ownership between system devices/resources are included to allow efficient access/ownership of shared data. Loose transaction ordering provided for while maintaining corresponding transaction priority to memory locations to ensure data integrity and efficient memory access. Active power sub-states and setting thereof is included to allow for more efficient power management. And, caching of device local memory in a host address space, as well as caching of system memory in a device local memory address space is provided for to improve bandwidth and latency for memory accesses.

Abstract: An apparatus and method for managing different page tables for different privilege levels. For example, one embodiment of a processor comprises: a first control register to store a first base address associated with program code executed at a first privilege level; a second control register to store a second base address associated with program code executed at a second privilege level lower than the first privilege level; and address translation circuitry to identify a first base translation table using the first base address responsive to a first address translation request originating from the program code executed at the first privilege level and to identify a second base translation table using the second base address responsive to a second address translation request originating from the program code executed at the second privilege level.

Abstract: In an embodiment, a method is provided. The method includes managing user-level threads on a first instruction sequencer in response to executing user-level instructions on a second instruction sequencer that is under control of an application level program. A first user-level thread is run on the second instruction sequencer and contains one or more user level instructions. A first user level instruction has at least 1) a field that makes reference to one or more instruction sequencers or 2) implicitly references with a pointer to code that specifically addresses one or more instruction sequencers when the code is executed.
