341  * counters. The events are encoded as event-code + umask-code.
342  *
343  * The event-code for all free running counters is 0xff, which is the same as
344  * the fixed counters.
345  *
346  * The umask-code is used to distinguish a fixed counter and a free running
347  * counter, and different types of free running counters.
348  * - For fixed counters, the umask-code is 0x0X.
349  *   X indicates the index of the fixed counter, which starts from 0.
350  * - For free running counters, the umask-code uses the rest of the space.
351  *   It would bare the format of 0xXY.
352  *   X stands for the type of free running counters, which starts from 1.
353  *   Y stands for the index of free running counters of same type, which
354  *   starts from 0.
355  *
356  * For example, there are three types of IIO free running counters on Skylake
357  * server, IO CLOCKS counters, BANDWIDTH counters and UTILIZATION counters.
358  * The event-code for all the free running counters is 0xff.
359  * 'ioclk' is the first counter of IO CLOCKS. IO CLOCKS is the first type,
360  * which umask-code starts from 0x10.
361  * So 'ioclk' is encoded as event=0xff,umask=0x10
362  * 'bw_in_port2' is the third counter of BANDWIDTH counters. BANDWIDTH is
363  * the second type, which umask-code starts from 0x20.
364  * So 'bw_in_port2' is encoded as event=0xff,umask=0x22
