[Xen-devel] [PATCH] Only trace 32-bit EIP when HVM is in 32-bit mode
Only trace 64 bits when in long mode. This trace happens every VMEXIT, and contributes significantly to trace size. Adding this patch reduces trace size for a parallel xen build by 7%. Signed-off-by: George Dunlap <george.dunlap@eu.citrix.com> (Again, hoping this will be counted as a bug-fix, since no new functionality is introduced.) _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
