在共享处理器调度周期结束之前,使用递减器中断启动长时间运行的硬件操作

Using a decrementer interrupt to start long-running hardware operations before the end of a shared processor dispatch cycle
Abstract:
Systems, methods, and computer program products to perform an operation, the operation comprising processing a first logical partition on a shared processor for the duration of a dispatch cycle, issuing, by a hypervisor, at a predefined time prior to completion of the dispatch cycle, a lightweight hypervisor decrementer (HDEC) interrupt specifying a cache line address buffer location in a virtual processor, and responsive to the lightweight HDEC, writing, by the shared processor, a set of cache line addresses used by the first logical partition to the cache line address buffer location in the virtual processor.
