阅读说明：本技术 有条件退让给管理程序指令 (Conditional yield to hypervisor instructions ) 是由 W·J·迪肯 M·津吉尔 于 2020-01-07 设计创作，主要内容包括：本发明公开了一种装置,该装置包括处理电路(16),该处理电路具有用于执行管理程序的管理程序执行模式,以及比该管理程序执行模式权限更低的至少一个较低权限执行模式,该管理程序用于管理在处理电路上执行的一个或多个虚拟处理器。响应于在该至少一个较低权限执行模式下执行的有条件退让给管理程序指令,指令解码器(14)控制处理电路(16)来：确定是否满足至少一个陷阱条件,以及当确定满足该至少一个陷阱条件时,将处理电路切换为管理程序执行模式；以及将至少一项调度提示信息存储在该管理程序执行模式下执行的指令可访问的至少一个存储元件中,该至少一项调度提示信息用于估计是否仍然满足该至少一个陷阱条件。(An apparatus includes a processing circuit (16) having a hypervisor execution mode for executing a hypervisor for managing one or more virtual processors executing on the processing circuit, and at least one lower-privilege execution mode lower-privilege than the hypervisor execution mode. In response to a conditional yield to hypervisor instructions executing in the at least one lower-privilege execution mode, instruction decoder (14) controls processing circuitry (16) to: determining whether at least one trap condition is satisfied, and switching the processing circuitry to a hypervisor execution mode when it is determined that the at least one trap condition is satisfied; and storing at least one scheduling hint information in at least one storage element accessible to instructions executing in the hypervisor execution mode, the at least one scheduling hint information used to estimate whether the at least one trap condition is still satisfied.)
