The only case of write_tsc() I see in the code is in arch/i386/kernel/smpboot.c, which is not used by the Xen PV implementation in RHEL-5. Where else in the PV implementation does a write_tsc? -- Chris Lalancette _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
