摘要： Methods and systems are provided to control transitions between a virtual machine (VM) and Virtual Machine Monitor (VMM). A processor uses state action indicators to load and/or store associated elements of machine state before completing the transition. The state action indicators may be stored in a Virtual Machine Control Structure (VMCS), predetermined, and/or calculated dynamically. In some embodiments, the values loaded can be directly acquired from the VMCS, predetermined and/or calculated dynamically. In some embodiments, the values stored may be acquired directly from machine state, predetermined and/or calculated dynamically.

摘要： Embodiments of apparatuses, methods, and systems for delivering an interrupt to a virtual processor are disclosed. In one embodiment, an apparatus includes an interface to receive an interrupt request, delivery logic, and exit logic. The delivery logic is to determine, based on an attribute of the interrupt request, whether the interrupt request is to be delivered to the virtual processor. The exit logic is to transfer control to a host if the delivery logic determines that the interrupt request is not to be delivered to the virtual processor.

摘要： In one embodiment of the present invention, an output device sends a spurious data sample in place of a first data sample to be sent from a queue if the queue is in a state of underflow during which the first data sample is not available to be sent. The buffer is to store data samples for an isochronous data transmission. Circuitry skips the first data sample when the first data sample becomes available in the queue so that synchronization for subsequent data samples sent from the queue is preserved. In another embodiment of the present invention, an input device advances an input buffer pointer to point to a next location in a memory in response to receiving a data sample at a queue during a state of overflow. The input buffer pointer indicates a location in the memory to which a next data sample is to be sent from the queue. The queue stores data samples for an isochronous data transmission. By advancing the input buffer pointer, synchronization for subsequent data samples is preserved.
摘要翻译：在本发明的一个实施例中，如果队列处于下溢状态，则第一数据样本不可用于发送，则输出设备发送伪数据样本代替要从队列发送的第一数据样本。缓冲区用于存储用于同步数据传输的数据样本。当第一个数据样本在队列中可用时，电路会跳过第一个数据样本，以便保留从队列发送的后续数据样本的同步。在本发明的另一实施例中，响应于在溢出状态期间在队列处接收到数据样本，输入装置使输入缓冲器指针前进到指向存储器中的下一个位置。输入缓冲区指针指示要从队列发送下一个数据样本的存储器中的位置。队列存储用于等时数据传输的数据样本。通过前进输入缓冲区指针，保留后续数据样本的同步。

摘要： The present invention protects against failures due to data unavailability in real-time data processing. The last state of data stored in an output buffer is computed, and a pointer is updated based on the last state of the data stored in the output buffer to point to a starting location of a buffer storing spurious data. In one embodiment, if the data stored in the output buffer is entirely consumed in real-time before new data is written, the pointer is used to begin consuming the spurious data in real-time.
