In the QMSS user guide (sprugr9f), in section 4.3.1.2 Global Timer Command Interface, it makes reference to the QMSS subsystem clock rate. What is the QM subsystem clock rate? Where is this documented?
The value of Timer Constant is the number of queue manager sub-system clocks
divided by 2 that comprise a single tick in the accumulator firmware.
For example, if the sub-system clock is 350 MHz (the default), and the desired firmware
tick is 20 μs, the proper timer constant for this command is calculated as follows:
