324 3. TSC Hardware
327 The TSC or time stamp counter is relatively simple in theory; it counts
332 The TSC is represented internally as a 64-bit MSR which can be read with the
334 limitations made it possible to write the TSC, but generally on old hardware it
339 write the TSC MSR is not an architectural guarantee.
341 The TSC is accessible from CPL-0 and conditionally, for CPL > 0 software by
342 means of the CR4.TSD bit, which when enabled, disables CPL > 0 TSC access.
345 atomically not just the TSC, but an indicator which corresponds to the
