| Thread-topic: | [PATCH] Reserve IO ports used by hotplug |
In DSDT, reserve the IO port ranges: [0x10c0, 0x10c2] and [0xb044, 0xb047] that are used by the virtual PCI hotplug. Or else, for a hotplugged-in device, the port IO BAR assigned by guest OS may conflict with the ranges here. Signed-off-by: Dexuan Cui <dexuan.cui@xxxxxxxxx>
