摘要： A device driver includes a kernel mode and a user-mode module. The device driver may access device registers while operating in user-mode to promote system stability while providing a low-latency software response from the system upon interrupts. The device driver may include kernel stubs that are loaded into the operating system, and may be device specific code written. The stubs may be called by a reflector to handle exceptions caught by the stubs. A reset stub may be invoked by the reflector when the user-mode module or host terminates abruptly or detects an interrupt storm. The reset stub may also be invoked if errant DMA operations are being performed by a hardware device. The reset stub may ensure that hardware immediately stops unfinished DMA from further transfer, and may be called by the user-mode driver module.

摘要： A device driver includes a hypervisor stub and a virtual machine driver module. The device driver may access device registers while operating within a virtual machine to promote system stability while providing a low-latency software response from the system upon interrupts. Upon receipt of an interrupt, the hypervisor stub may run an interrupt service routine and write information to shared memory. Control is passed to the virtual machine driver module by a reflector. The virtual machine driver module may then read the information from the shared memory to continue servicing the interrupt.
