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 management 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.
|
|
|
|
This protocol library provides interface for all the client drivers
|
|
making use of the features offered by the SCP.

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.)

bool "Mark VGA/VBE/EFI FB as generic system framebuffer"

help
|
|
Firmwares often provide initial graphics framebuffers so the BIOS,
|
|
bootloader or kernel can show basic video-output during boot for
|
|
user-guidance and debugging. Historically, x86 used the VESA BIOS
|
|
Extensions and EFI-framebuffers for this, which are mostly limited
|
|
to x86 BIOS or EFI systems.
|
|
This option, if enabled, marks VGA/VBE/EFI framebuffers as generic
|
|
framebuffers so the new generic system-framebuffer drivers can be
|
|
used instead. If the framebuffer is not compatible with the generic
|
|
modes, it is advertised as fallback platform framebuffer so legacy
|
|
drivers like efifb, vesafb and uvesafb can pick it up.
|
|
If this option is not selected, all system framebuffers are always
|
|
marked as fallback platform framebuffers as usual.
|
|
|
|
Note: Legacy fbdev drivers, including vesafb, efifb, uvesafb, will
|
|
not be able to pick up generic system framebuffers if this option
|
|
is selected. You are highly encouraged to enable simplefb as
|
|
replacement if you select this option. simplefb can correctly deal
|
|
with generic system framebuffers. But you should still keep vesafb
|
|
and others enabled as fallback if a system framebuffer is
|
|
incompatible with simplefb.
|
|
|
|
If unsure, say Y.
