摘要： A method and apparatus for extending cache coherency to hold buffered data to support transactional execution is herein described. A transactional store operation referencing an address associated with a data item is performed in a buffered manner. Here, the coherency state associated with cache lines to hold the data item are transitioned to a buffered state. In response to local requests for the buffered data item, the data item is provided to ensure internal transactional sequential ordering. However, in response to external access requests, a miss response is provided to ensure the transactionally updated data item is not made globally visible until commit. Upon commit, the buffered lines are transitioned to a modified state to make the data item globally visible.

摘要： A method and apparatus for monitoring memory accesses in hardware to support transactional execution is herein described. Attributes are monitor accesses to data items without regard for detection at physical storage structure granularity, but rather ensuring monitoring at least at data items granularity. As an example, attributes are added to state bits of a cache to enable new cache coherency states. Upon a monitored memory access to a data item, which may be selectively determined, coherency states associated with the data item are updated to a monitored state. As a result, invalidating requests to the data item are detected through combination of the request type and the monitored coherency state of the data item.

摘要： A method and apparatus for metaphysical address space for holding lossy metadata is herein described. An explicit or implicit metadata access operation referencing data address of a data item is encountered. Hardware modifies the data address to a metadata address including a metaphysical extension. The metaphysical extension overlays one or more metaphysical address space(s) on the data address space. A portion of the metadata address including the metaphysical extension is utilized to search a tag array of the cache memory holding the data item. As a result, metadata access operations only hit metadata entries of the cache based on the metadata address extension. However, as the metadata is held within the cache, the metadata potentially competes with data for space within the cache.

摘要： A method and apparatus for providing a memory model for hardware attributes to support transactional execution is herein described. Upon encountering a load of a hardware attribute, such as a test monitor operation to load a read monitor, write monitor, or buffering attribute, a fault is issued in response to a loss field indicating the hardware attribute has been lost. Furthermore, dependency actions, such as blocking and forwarding, are provided for the attribute access operations based on address dependency and access type dependency. As a result, different scenarios for attribute loss and testing thereof are allowed and restricted in a memory model.

摘要： A method and apparatus for optimizing an Unbounded Transactional Memory (UTM) system is herein described. Hardware support for monitors, buffering, and metadata is provided, where orthogonal metaphysical address spaces for metadata may be separate associated with threads and/or software subsystems within threads. In addition, the metadata may be held with hardware in a compressed manner with regard to data transparently to software. Furthermore, in response to metadata access instruction/operations the hardware is capable of supporting a forced metadata value to enable multiple modes of transactional execution. However, if monitors, buffered data, metadata, or other information is lost or conflicts are detected hardware provides for variations of a loss instruction that is able to poll a transaction status register for such loss or conflict and jump execution to a label in response to detecting the loss or conflict. Similarly, multiple variations of a commit instruction are provided for to allow software to define commit conditions and information to clear upon commit. Furthermore, hardware provides support to enable suspension and resume of transactions upon ring level transitions.

摘要： In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for implementing efficient communication between caches in hierarchical caching design. For example, in one embodiment, such means may include an integrated circuit having a data bus; a lower level cache communicably interfaced with the data bus; a higher level cache communicably interfaced with the data bus; one or more data buffers and one or more dataless buffers. The data buffers in such an embodiment being communicably interfaced with the data bus, and each of the one or more data buffers having a buffer memory to buffer a full cache line, one or more control bits to indicate state of the respective data buffer, and an address associated with the full cache line. The dataless buffers in such an embodiment being incapable of storing a full cache line and having one or more control bits to indicate state of the respective dataless buffer and an address for an inter-cache transfer line associated with the respective dataless buffer. In such an embodiment, inter-cache transfer logic is to request the inter-cache transfer line from the higher level cache via the data bus and is to further write the inter-cache transfer line into the lower level cache from the data bus.
