From cecde1f9670adb95274c56e126d62d8a6d86f8cf Mon Sep 17 00:00:00 2001 From: Keir Fraser Date: Tue, 29 Jun 2010 18:17:44 +0100 Subject: [PATCH] Use fixed-width types in the memory event interface Set the types in the public memory_event header file to use fixed-sized and self-aligned fields rather than "unsigned long". AIUI this feature only works with 64-bit hypervisors but I think this change will be necessary to use 32-on-64 dom0 tools. This breaks compatibility with older builds of the tools, but I can't see any way to avoid it short of __attribute__((__packed__)).
