No, not for all DIG64 compliant IPF platforms. NEC TX7 is also a DIG64 compliant IPF platform but doesn't need your driver. DIG64(2.1) only states that: Firmware Support for PCI Hot-Plug : Recommended if PCI Hot-Plug is implemented ACPI Support for PCI Hot-Plug : Recommended for platforms that implement PCI Hot-Plug without SHPC Using PCI Hot-Plug Specifications : Recommended if PCI Hot-Plug is implemented The spec also states that any PCI Hot-Plug controller must follow one of PCI Hot-Plug spec 1.1, SHPC 1.0 or CompactPCI Hot Swap spec. It also strongly recommends SHPC 1.0, which is not covered by J.I.'s driver yet. But anyway Itanium2 platform using intel's hot-plug controller will be shipping soon and J.I.'s driver has much better functionality than acpiphp. This would be a decent reason for having the driver in the mainline. And this also motivates us to clean up the duplicated code if it were in mainline:) Thanks, -- KOCHI, Takayoshi
