On some of these SoCs it's not possible to # recalibrate the TSC because there is no reference (PIT, HPET) # available. # # With some reverse engineering it was established that the possible # frequencies are derived from the base clock with fixed multiplier / # divider pairs. # # For the CPU models which have a known crystal frequency the kernel now # uses multiplier / divider pairs which bring the frequencies closer to # reality and fix the observed time drift issues" #
