Could the DSDT just not define _EJ0 for device 1 & 2 instead of dynamically patching them? (Would there ever be a case where we wouldn't know at compile time which devices need _EJ0?) > The correct way to suppress hotplug is not to have _EJ0, > so this is what this patch does: it probes PIIX and > modifies DSDT to match. The code to generate basic SSDT code isn't that difficult (see build_ssdt and src/ssdt-proc.dsl). Is there a compelling reason to patch the DSDT versus just generating the necessary blocks in an SSDT? -Kevin -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
