摘要： Techniques and mechanisms for providing access to a storage device of a computer platform. In an embodiment, an agent executing on the platform may be registered for access to the storage device, the agent being allocated a memory space by a host operating system of the platform. Registration of the agent may result in a location in the allocated memory space being mapped to a location in the storage device. In another embodiment, the agent may write to the location in the allocated memory space to request access to the storage device, wherein the request is independent of any system call to the host OS which describes the requested access.

摘要： Provided are a method, system, and program for handling Input/Output (I/O) requests. A bus enables communication with an initiator, target device and device controller, wherein the device controller accesses the target device to execute I/O commands directed to the target device. An I/O request command is received to access the target device. The initiator is configured to transmit at least one data request on the bus to one memory address in a predefined address window of the device controller. The device controller is enabled to claim the data request to the memory address in the predefined address window from the initiator on the bus to execute the data request against the target device.

摘要： An apparatus and/or system is described including a memory device including a memory range and a temporal data management unit (TDMU) coupled to the memory device to receive from an interface, the memory range and a temporal range corresponding to validity of data in the memory range, check the temporal range against a time and/or date value provided by a timer or clock to identify the data in the memory range as expired, and invalidate the data that is expired in the memory device. In some embodiments, the TDMU includes hardware logic that resides on a memory module with the memory device and is coupled to invalidate expired data when the memory module is decoupled from the interface. Other embodiments may be disclosed and claimed.

摘要： An apparatus according to one embodiment may include an integrated circuit. The integrated circuit may include a processor, a bridge, and circuitry capable of coupling the bridge and the processor to a first bus and to a second bus. The first bus may be compatible with a first bus protocol, the second bus may be compatible with a second bus protocol, and the first and second bus protocols may be different from each other. The bridge may be capable of, in response at least in part to a request from the processor, preventing a command received at the bridge via the first bus from being forwarded from the bridge to the second bus. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

摘要： A method for providing a base address register in a computer system that allows the length of the base address portion of an address to be changed and thereby allows various sizes of address spaces to be supported by the same base address register. The method employs steps that enable and disable bits of the base address register to properly support the desired address space size. Some embodiments of the method set disabled bits of the base address register to a known value. An apparatus that employs the method includes a second register connected to the base address register to supply signals that enable and disable bits of the base address register appropriately.

摘要： A system and method are described for selecting a demarcation voltage for read and write operations. Embodiments of the invention provide a scheme to use multiple VDMs to cover the case where power-on drift is different from power-off drift of the PCMS cells. The controller automatically manages this through tracking refreshes and writes. In addition, the embodiments of the invention provide an efficient scheme to reduce the performance impact of the penalty box following a write by tracking recent write addresses through a hash-table or similar scheme. By way of example, a method in accordance with one embodiment comprises: detecting a read operation directed to a first block of a PCMS memory; determining whether a write operation has previously occurred to the first block within a specified amount of time prior to the read operation; using a first demarcation voltage (VDM) for the read operation if the write operation has previously occurred to the first block within the specified amount of time prior to the write operation; and using a second VDM for the read operation if the write operation has not previously occurred to the first block within the specified amount of time prior to the write or refresh operation.
摘要翻译：描述了用于选择用于读取和写入操作的分界电压的系统和方法。本发明的实施例提供了使用多个VDM来覆盖上电漂移与PCMS单元的断电漂移不同的情况的方案。控制器通过跟踪刷新和写入自动进行管理。此外，本发明的实施例提供了一种有效的方案，以通过通过散列表或类似方案跟踪最近的写入地址来减少写入之后的惩罚盒的性能影响。作为示例，根据一个实施例的方法包括：检测针对PCMS存储器的第一块的读取操作; 在所述读取操作之前的指定时间内确定是否先前对所述第一块发生了写入操作; 如果在写操作之前的指定时间内先前已经对第一块发生写操作，则使用第一分界电压（VDM）作为读操作; 以及如果在所述写入或刷新操作之前的所述指定时间量内的所述第一块以前没有发生写入操作，则使用第二VDM进行所述读取操作。
