How can I use a semaphore in a function that I use in /xen/arch/x86/traps.c , xen version 4.0.1 I implement the function in the same level /xen/arch/x86/ and so used in ring0. i''ve to add a semaphore for a producer-consumer system. and a semaphore (or a wait) for a condition. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
