[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] Finding guest calling function
In the hypervisor, I can use regs->eip to get the location of a trapped instruction in a guest (in this case rdtsc) which allows me to determine the function in which the trapping instruction was used. Is there any easy way to determine the function that CALLED the function in which the trapping instruction was used? If so, is there any example code in Xen that I can steal from? (This is for a find-the-guest-kernel-rdtsc-uses exercise from another thread... all the rdtsc uses are in native_read_tsc so I need to know the frequencies of what is calling native_read_tsc.) Thanks, Dan _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
