Important pieces of hardware should get an in-KVM simulator/emulator, that way developers who do not own that hardware can do functionality testing too. So basically the highest-quality drivers would have an "inverse driver" in KVM, which simulates the hardware. (that model is evidently useful to the hardware maker even for new hardware: it can then also be used to test the Linux compatibility and Linux performance of future planned releases of the hardware, etc.) Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
