12 PMU doesn't support process specific events and cannot be used in sampling mode.
14 The DSU provides a bitmap for a subset of implemented events via hardware
15 registers. There is no way for the driver to determine if the other events
16 are available or not. Hence the driver exposes only those events advertised
17 by the DSU, in "events" directory under::
21 The user should refer to the TRM of the product to figure out the supported events
22 and use the raw event code for the unlisted events.
