LEVERAGING TRANSACTIONAL MEMORY HARDWARE TO ACCELERATE VIRTUALIZATION AND EMULATION |
摘要 |
Various technologies and techniques are disclosed for using transactional memory hardware to accelerate virtualization or emulation. A central processing unit is provided with the transactional memory hardware. Code backpatching can be facilitated by providing transactional memory hardware that supports a facility to maintain private memory state and an atomic commit feature. Changes made to certain code are stored in the private state facility. Backpatching changes are enacted by attempting to commit all the changes to memory at once using the atomic commit feature. An efficient call return stack can be provided by using transactional memory hardware. A call return cache stored in the private state facility captures a host address to return to after execution of a guest function completes. A direct-lookup hardware-based hash table is used for the call return cache. |
