jkim faed140c1e Introduce low-resolution TSC timecounter "TSC-low". It replaces the normal ... TSC timecounter if TSC frequency is higher than ~4.29 MHz (or 2^32-1 Hz) or multiple CPUs are present. The "TSC-low" frequency is always lower than a preset maximum value and derived from TSC frequency (by being halved until it becomes lower than the maximum). Note the maximum value for SMP case is significantly lower than UP case because we want to reduce (rare but known) "temporal anomalies" caused by non-serialized RDTSC instruction. Normally, it is still higher than "ACPI-fast" timecounter frequency (which was default timecounter hardware for long time until r222222) to be useful.		2011-06-08 19:38:31 +00:00
