摘要： Embodiments of systems, apparatuses, and methods for a circular buffer in a redundant virtualization environment are disclosed. In one embodiment, an apparatus includes a head indicator storage location, an outgoing tail indicator storage location, a buffer tail storage location, and fetch hardware. The head indicator, outgoing tail indicators, and buffer tail indicators are to indicate a head, outgoing tail, and buffer tail, respectively, of a circular buffer. The fetch hardware is to fetch from the head of the circular buffer and advance the head no further than the outgoing tail. The buffer tail is to be filled by software and advanced no further than the head.
