Abstract: Methods and apparatus are disclosed for virtualizable, forward-compatible hardware-software interfaces. Embodiments may be used in a driver whether it is a physical driver or a virtual driver. Commands are queued from the driver and fetched to the device. An actions table is accessed to determine if drivers are permitted to perform commands. Events are queued for the drivers responsive to commands. If drivers are not permitted to perform a command, device firmware may forward the command to a privileged driver to perform the required command. If a driver is only permitted to perform a command with assistance the command is forwarded for corrections and execution. If a command is to be dropped, a completion event may be queued as if the command had executed. Drivers may have no indication of which actions were taken. The actions table may be changed for hardware/software modifications or dynamically according to configuration changes.

Abstract translation: 公开了用于可虚拟化，前向兼容的硬件 - 软件接口的方法和装置。 驱动器中可以使用实施例，无论其是物理驱动器还是虚拟驱动器。 命令从驱动程序排队并提取到设备。 访问一个动作表以确定是否允许驱动程序执行命令。 事件针对响应于命令的驱动程序排队等候。 如果驱动程序不允许执行命令，则设备固件可将命令转发给特权驱动程序以执行所需的命令。 如果仅允许驱动程序执行命令，则该命令将被转发以进行更正和执行。 如果要删除命令，则完成事件可能会像命令执行一样排队。 司机可能没有指出采取了哪些行动。 可以针对硬件/软件修改或动态地根据配置更改来更改动作表。
