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

26 | help |
27 | System Control and Power Interface (SCPI) Message Protocol is | |
28 | defined for the purpose of communication between the Application | |
29 | Cores(AP) and the System Control Processor(SCP). The MHU peripheral | |
30 | provides a mechanism for inter-processor communication between SCP | |
31 | and AP. | |
32 | ||
33 | SCP controls most of the power managament on the Application | |
34 | Processors. It offers control and management of: the core/cluster | |
35 | power states, various power domain DVFS including the core/cluster, | |
36 | certain system clocks configuration, thermal sensors and many | |
37 | others. | |
38 | ||
39 | This protocol library provides interface for all the client drivers | |
40 | making use of the features offered by the SCP. | |

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

98 | ||
99 | If your firmware supplies the HCDP table, and you want to | |
100 | use the first serial port it describes as the Linux console, | |
101 | say Y here. If your EFI ConOut path contains only a UART | |
102 | device, it will become the console automatically. Otherwise, | |
103 | you must specify the "console=hcdp" kernel boot argument. | |
104 | ||
105 | Neither the PCDP nor the HCDP affects naming of serial devices, | |
106 | so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending | |
107 | on how the driver discovers devices. | |
108 | ||
109 | You must also enable the appropriate drivers (serial, VGA, etc.) | |
