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

Cores(AP) and the System Control Processor(SCP). The MHU peripheral

provides a mechanism for inter-processor communication between SCP
|

and AP.
|

SCP controls most of the power managament on the Application

Processors. It offers control and management of: the core/cluster

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

|
automatically use the primary console device it describes
|
|
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.)
