I was going to ask you about this. I am writing on a patch that puts all the ACM hypercall structures into a union. I am wondering what the compat stuff is for (xen/common/compat) and what the criterion is for needing this compat code.
If you have structures that differ in layout in 32-bit mode vs. 64-bit mode then you need a compat shim when running 32-bit dom0 on 64-bit Xen (which we support doing nowadays). Currently you have no such issues that I’m aware of. You should be able to delete the compat stuff that is there currently with no problems.
Is the build failure in Xen itself or in tools? I’m sure it’s easily fixed without needing to throw away the GUEST_HANDLE_64() usage.
