Abstract: A method and apparatus for supporting programmable software context state execution during hardware context restore flow is described. In one example, a context ID is assigned to graphics applications including a unique context memory buffer, a unique indirect context pointer and a corresponding size to each context ID, an indirect context offset, and an indirect context buffer address range. When execution of the first context workload is indirected, the state of the first context workload is saved to the assigned context memory buffer. The indirect context pointer, the indirect context offset and a size of the indirect context buffer address range are saved to registers that are independent of the saved context state. The context is restored by accessing the saved indirect context pointer, the indirect context offset and the buffer size.

Abstract translation: 描述了用于在硬件上下文恢复流程期间支持可编程软件上下文状态执行的方法和装置。 在一个示例中，上下文ID被分配给包括唯一上下文存储器缓冲器，唯一间接上下文指针和对每个上下文ID，间接上下文偏移以及间接上下文缓冲器地址范围的对应大小的图形应用。 当第一上下文工作负载的执行被间接时，第一上下文工作负载的状态被保存到所分配的上下文存储器缓冲器中。 间接上下文指针，间接上下文偏移量和间接上下文缓冲区地址范围的大小保存到独立于保存的上下文状态的寄存器中。 通过访问保存的间接上下文指针，间接上下文偏移量和缓冲区大小来恢复上下文。
