You mean that the TF bit is not cleared by the domu_debug code when it should be? The correct place to fix this is in include/asm-x86/debugger.h in debugger_trap_entry(). In general (not using domu_debug) it is not Xen's job to clear TF. We clear it when we 'bounce' the exception into the guest OS, but the saved application stack frame will include EFLAGS with the TF bit still set. This matches real hardware. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
