what if your tb wraps during the test?
Per the Power ISA, Time Base is 64 bits, monotonically increasing, and
is writable only in hypervisor state. To my understanding, it is set to
zero at boot (although this is not prescribed).
Also, as noted
The POWER ISA defines an always-running decrementer which can be used
to schedule interrupts after a certain time interval has elapsed.
The decrementer counts down at the same frequency as the Time Base,
which is 512 MHz. The maximum value of the decrementer is 0x7fff.
This works out to a
