 264  * In the uncore document, there is no event-code assigned to free running
 265  * counters. Some events need to be defined to indicate the free running
 266  * counters. The events are encoded as event-code + umask-code.
 267  *
 268  * The event-code for all free running counters is 0xff, which is the same as
 269  * the fixed counters.
 270  *
 271  * The umask-code is used to distinguish a fixed counter and a free running
 272  * counter, and different types of free running counters.
 273  * - For fixed counters, the umask-code is 0x0X.
 274  *   X indicates the index of the fixed counter, which starts from 0.
 275  * - For free running counters, the umask-code uses the rest of the space.
 276  *   It would bare the format of 0xXY.
 277  *   X stands for the type of free running counters, which starts from 1.
 278  *   Y stands for the index of free running counters of same type, which
 279  *   starts from 0.
 280  *
 281  * For example, there are three types of IIO free running counters on Skylake
 282  * server, IO CLOCKS counters, BANDWIDTH counters and UTILIZATION counters.
 283  * The event-code for all the free running counters is 0xff.
 284  * 'ioclk' is the first counter of IO CLOCKS. IO CLOCKS is the first type,
 285  * which umask-code starts from 0x10.
 286  * So 'ioclk' is encoded as event=0xff,umask=0x10
 287  * 'bw_in_port2' is the third counter of BANDWIDTH counters. BANDWIDTH is
 288  * the second type, which umask-code starts from 0x20.
 289  * So 'bw_in_port2' is encoded as event=0xff,umask=0x22
