| H A D | arch_timer.cpp | diff bb2808d6 Tue Oct 24 15:54:55 MDT 2023 Augustin Cavalier <waddlesplash@gmail.com> bootloader: Implement TSC calibration via hypervisor CPUID leaf. While debugging some problems on the HaikuPorts build VMs, mmlr noticed their clocks had an alarming amount of drift. This prompted an investigation into TSC calibration mechanisms, and the discovery that there is a VM-specific one which we did not implement. This mechanism is more accurate than counting cycles on VMs where cycles can be "stolen" (the probable cause of the aforementioned clock drift.) Tested in VMware (works out of the box) and on QEMU/KVM (may need TSC frequency specified or a host with invariant TSC.)
