Do you have any plans for how to support ENQCMD{,S} which are just variations of MOVDIR64B using the F2 and F3 prefixes for behaviour modification, and whether those might alter what we do here? The underlying write out into the system is going to be largely the same, but it can't be shared with MOVDIR64B because it generates a different type of bus transaction. Also, they require ZF to find their way back out of the rmw() handler. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
