config ARM_CCI400_PMU
bool "ARM CCI400 PMU support"
depends on (ARM && CPU_V7) || ARM64
select ARM_CCI400_COMMON
select ARM_CCI_PMU
help
Support for PMU events monitoring on the ARM CCI-400 (cache coherent
interconnect). CCI-400 supports counting events related to the
connected slave/master interfaces.

depends on (ARM && CPU_V7) || ARM64
select ARM_CCI_PMU
help
Support for PMU events monitoring on the ARM CCI-500/CCI-550 cache
coherent interconnects. Both of them provide 8 independent event counters,
which can count events pertaining to the slave/master interfaces as well
as the internal events to the CCI.
If unsure, say Y
