Add a function to detect the existence of the CPU Measurement Sampling Facility on a system. Add a function which extracts the CPU Measurement Sampling Facility characteristics on a system, such as - minimum sample speed - maximum sample speed - current CPU speed - basic sample size in bytes - diagnostic sample size in bytes Add a function to detect the existence of the CPU Measurement Sampling Facility on a system and return the current sampling buffer management characteristics, such as: - minimum supported sampling buffer size - maximum supported sampling buffer size Add a function to detect the existence of the CPU Measurement Counting Facility on a system. Add a function which extracts the CPU Measurement Counting Facility characteristics on a system, such as - counter first version number - counter second version number - counter set authorization level Add a function the returm the PMU type number of a CPU Measurement Facility device driver. These numbers may vary between boots. Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Acked-by: Sumanth Korikkar <sumanthk@linux.ibm.com> Signed-off-by: Jan Höppner <hoeppner@linux.ibm.com>
