Abstract: Systems, apparatuses and methods may provide for technology that establishes a point of intersection based on a rate of change in a logarithmic function and generates a first linear estimation of the logarithmic function, wherein the first linear estimation has the point of intersection as an upper bound. Additionally, a second linear estimation of the logarithmic function may be generated, wherein the second linear estimation has the point of intersection as a lower bound. In one example, linear estimations of an antilogarithmic function may be similarly generated based on the rate of change of the antilogarithmic function.

Abstract: Particular embodiments described herein provide for an electronic device that can be configured to receive a request for a timestamp associated with a virtual machine, determine a current time from a timestamp counter, and subtract a timing compensation from the current time from the timestamp counter to create the timestamp, where the timing compensation includes an amount of time that execution of the virtual machine was suspended. In an example, a VM_EXIT instruction was used to suspend execution of the virtual machine and the timestamp counter was read before the VM_EXIT instruction was processed by a hypervisor.
