The torture tests may interfere with the PSCI checker by turning CPUs

ARM System Control and Management Interface (SCMI) protocol is a
|

|
|
set of operating system-independent software interfaces that are
|
||
|
|
used in system management. SCMI is extensible and currently provides
|
||
|
|
interfaces for: Discovery and self-description of the interfaces
|
||
|
|
it supports, Power domain management which is the ability to place
|
||
|
|
a given device or domain into the various power-saving states that
|
||
|
|
it supports, Performance management which is the ability to control
|
||
|
|
the performance of a domain that is composed of compute engines
|
||
|
|
such as application processors and other accelerators, Clock
|
||
|
|
management which is the ability to set and inquire rates on platform
|
||
|
|
managed clocks and Sensor management which is the ability to read
|
||
|
|
sensor data, and be notified of sensor value.
|
||
|
|
|
||

This protocol library provides interface for all the client drivers

making use of the features offered by the SCMI.

Neither the PCDP nor the HCDP affects naming of serial devices,

You must also enable the appropriate drivers (serial, VGA, etc.)
