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