It is possible to build the driver for "IRQless" operation but currently that is only done for non x86 platforms (eg Sparc). So if it gets loaded on x86, IRQ 8 was free. But /sbin/hwclock depending on the version has some other uglies too. Some versions of it if they find no /dev/rtc will iopl() as root and then proceed to whack the hardware directly. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
