Indeed. But the Macs are a little weird in this respect, it does not necessarily mean they don't implement LocateHandleBuffer(). Since Lukas uses a Mac himself (IIRC), I'd assume it works on his system and so their UEFI does implement this boot service. That does not necessarily tell us anything about other Macs, though. So I'm a bit on the fence here: we could mandate a more recent version of UEFI if the Mac is the only 'older' implementation we intend to support, but it is not a very clean approach imo, and this particular patch, while useful, does not use a critical piece of functionality that is only implemented by newer spec revisions. I am leaning towards not taking the patch, although we could revisit this in the future. -- Ard. -- To unsubscribe from this list: send the line "unsubscribe linux-efi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
