Aren't there flags in the binary somewhere that could tell the toolstack / Xen whether the kernel in question needs the RSDP table in lowmem, or whether it can be put higher?
Not really. Analyzing the binary whether it accesses the rsdp_addr in the start_info isn't the way to go, IMO.
I've sent a patch to xen-devel adding a quirk flag to the domain's config to enable the admin special casing such an "old" kernel.
Can we backport latest struct hvm_start_info changes (which bumped interface version) to 4.11 and pass RSDP only for versions >=1?
