Maximum Power Mitigation Mechanism (MPMM) Bindings
|MPMM| support cannot be determined at runtime by the firmware. Instead, these DTB bindings allow the platform to communicate per-core support for |MPMM| via the HW_CONFIG device tree blob.
Bindings
/cpus/cpus/cpu* node properties
The cpu node has been augmented to allow the platform to indicate support for |MPMM| on a given core.
Property name | Usage | Value type | Description |
---|---|---|---|
supports-mpmm | O | <empty> | If present, indicates that |MPMM| is available on this core. |
Example
An example system offering two cores, one with support for |MPMM| and one without, can be described as follows:
cpus { #address-cells = <2>; #size-cells = <0>; cpu0@00000 { ... supports-mpmm; }; cpu1@00100 { ... }; }
