This interface is responsible for handling the communication
with RIMPS PLH such as passing tunables, enable and disable.
config MSM_PERFORMANCE_QGKI

depends on QGKI
help
This option enables full functionality of MSM_PERFORMANCE for
QGKI flavor. This is not defined in GKI builds wherein the driver
offers minimal functionality of changing the min and max frequency
of a given cluster. The user space can request the cpu freq change
by writing cpu#:freq values
config QMP_DEBUGFS_CLIENT
bool "Debugfs Client to communicate with AOP using QMP protocol"
depends on DEBUG_FS
