Abstract: Methods and apparatuses relating to hardware processors with multiple interconnected dies are described. In one embodiment, a hardware processor includes a plurality of physically separate dies, and an interconnect to electrically couple the plurality of physically separate dies together. In another embodiment, a method to create a hardware processor includes providing a plurality of physically separate dies, and electrically coupling the plurality of physically separate dies together with an interconnect.

Abstract: A physical layer (PHY) is coupled to a serial, differential link that is to include a number of lanes. The PHY includes a transmitter and a receiver to be coupled to each lane of the number of lanes. The transmitter coupled to each lane is configured to embed a clock with data to be transmitted over the lane, and the PHY periodically issues a blocking link state (BLS) request to cause an agent to enter a BLS to hold off link layer flit transmission for a duration. The PHY utilizes the serial, differential link during the duration for a PHY associated task selected from a group including an in-band reset, an entry into low power state, and an entry into partial width state

Abstract: Method and system for performing data movement operations is described herein. One embodiment of a method includes: storing data for a first memory address in a cache line of a memory of a first processing unit, the cache line associated with a coherency state indicating that the memory has sole ownership of the cache line; decoding an instruction for execution by a second processing unit, the instruction comprising a source data operand specifying the first memory address and a destination operand specifying a memory location in the second processing unit; and responsive to executing the decoded instruction, copying data from the cache line of the memory of the first processing unit as identified by the first memory address, to the memory location of the second processing unit, wherein responsive to the copy, the cache line is to remain in the memory and the coherency state is to remain unchanged.

Abstract: Provided are an apparatus and method for a non-power-of-2 size cache in a first level memory device to cache data present in a second level memory device having a 2n cache size. A request is to a target address having n bits directed to the second level memory device. A determination is made whether a target index, comprising m bits of the n bits of the target address, is within an index set of the first level memory device. A determination is made of a modified target index in the index set of the first level memory device having at least one index bit that differs from a corresponding at least one index bit in the target index. The request is processed with respect to data in a cache line at the modified target index in the first level memory device.

Abstract: A memory controller receives a memory invalidation request that references a line of far memory in a two level system memory topology with far memory and near memory, identifies an address of the near memory corresponding to the line, and reads data at the address to determine whether a copy of the line is in the near memory. Data of the address is to be flushed to the far memory if the data includes a copy of another line of the far memory and the copy of the other line is dirty. A completion is sent for the memory invalidation request to indicate that a coherence agent is granted exclusive access to the line. With exclusive access, the line is to be modified to generate a modified version of the line and the address of the near memory is to be overwritten with the modified version of the line.
