16 System Control and Power Interface (SCPI) Message Protocol is
17 defined for the purpose of communication between the Application
18 Cores(AP) and the System Control Processor(SCP). The MHU peripheral
19 provides a mechanism for inter-processor communication between SCP
20 and AP.
21
54da51a8 22 SCP controls most of the power management on the Application

23 Processors. It offers control and management of: the core/cluster
24 power states, various power domain DVFS including the core/cluster,
25 certain system clocks configuration, thermal sensors and many
26 others.
27
28 This protocol library provides interface for all the client drivers
29 making use of the features offered by the SCP.

96 so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending

238 Firmwares often provide initial graphics framebuffers so the BIOS,

JMC
243 This option, if enabled, marks VGA/VBE/EFI framebuffers as generic
244 framebuffers so the new generic system-framebuffer drivers can be
8633ef82 245 used instead. If the framebuffer is not compatible with the generic
d391c582
JMC
246 modes, it is advertised as fallback platform framebuffer so legacy
247 drivers like efifb, vesafb and uvesafb can pick it up.
248 If this option is not selected, all system framebuffers are always
249 marked as fallback platform framebuffers as usual.
250
251 Note: Legacy fbdev drivers, including vesafb, efifb, uvesafb, will
252 not be able to pick up generic system framebuffers if this option
253 is selected. You are highly encouraged to enable simplefb as
254 replacement if you select this option. simplefb can correctly deal
255 with generic system framebuffers. But you should still keep vesafb
256 and others enabled as fallback if a system framebuffer is
257 incompatible with simplefb.
