[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [patch rfc 1/3] xen arch header rework.
This patch makes arch-specific types and structs be postfixed by the
architecture name. The native ones are defined to the non-postfixed
versions. Also changed struct elements to use uint{32,64}_t everywhere
so we get the correct sizes no matter what sizeof(long) happens to be.
The goal of this work is to be able to include foreign arch headers
within one source file and be able to deal with foreign structs in the
xen tools.
For now I've started with x86_32 and x86_64, we'll need that first
when supporting 32-on-64 paravirtualized guests.
