Include support for Intel uncore performance events. These are
available on NehalemEX and more modern processors.

tristate "AMD Processor Power Reporting Mechanism"
help
Provide power reporting mechanism support for AMD processors.
Currently, it leverages X86_FEATURE_ACC_POWER
(CPUID Fn8000_0007_EDX[12]) interface to calculate the
average power consumption on Family 15h processors.

default y
help
Include support for AMD uncore performance events for use with
e.g., perf stat -e amd_l3/.../,amd_df/.../.
To compile this driver as a module, choose M here: the
module will be called 'amd-uncore'.

bool "AMD Zen3 Branch Sampling support"
help
Enable AMD Zen3 branch sampling support (BRS) which samples up to
16 consecutive taken branches in registers.
