Run the PSCI checker during startup. This checks that hotplug and

suspend operations work correctly when using PSCI.

The torture tests may interfere with the PSCI checker by turning CPUs
|
|
on and off through hotplug, so for now torture tests and PSCI checker

are mutually exclusive.

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.

System Control and Power Interface (SCPI) Message Protocol is

defined for the purpose of communication between the Application

provides a mechanism for inter-processor communication between SCP

SCP controls most of the power managament on the Application

power states, various power domain DVFS including the core/cluster,

certain system clocks configuration, thermal sensors and many

others.

If your firmware supplies the PCDP table, and you want to

as the Linux console, say Y here.
|

If your firmware supplies the HCDP table, and you want to

use the first serial port it describes as the Linux console,

say Y here. If your EFI ConOut path contains only a UART
|
|
device, it will become the console automatically. Otherwise,
|
|
you must specify the "console=hcdp" kernel boot argument.
|
|
|
|
Neither the PCDP nor the HCDP affects naming of serial devices,
|
|
so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
|
|
on how the driver discovers devices.
|
|
|
|
You must also enable the appropriate drivers (serial, VGA, etc.)
