This might be a useful source for making ACPI compatible with Windows. http://dslab.epfl.ch/pubs/revnic
I had thought of a project like this before. My idea was to take QEMU and map PCI config space and allow direct access to the bare hardware for only one device. The developer would install Windows in this QEMU image on a system with the target device, identify it by its PCI id, and then run Windows normally. The VM would log the driver's accesses to config space as well as use CoW semantics for DMA accesses to memory and IO ports. Now that Intel/AMD support hardware virtualization and DMA isolation, it would be better to do this with a modified Xen hypervisor. -- Nate _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "[email protected]"
