AMD X3D processors, also known as AMD 3D V-Cache, feature dual Core Complex Dies (CCDs) and enlarged L3 cache, enabling dynamic mode switching between Frequency and Cache modes. To optimize performance, implement the AMD 3D V-Cache Optimizer, which allows selecting either: Frequency mode: cores within the faster CCD are prioritized before those in the slower CCD. Cache mode: cores within the larger L3 CCD are prioritized before those in the smaller L3 CCD.

The driver provides a sysfs interface, enabling the setting of a bias
|
|
that alters CPU core reordering. This bias prefers cores with higher
|
|
frequencies or larger L3 caches on processors supporting AMD 3D V-Cache
|
|
technology.
|
|
|
|
If you choose to compile this driver as a module the module will be
|
|
called amd_3d_vcache.

help
|
|
WBRF(Wifi Band RFI mitigation) mechanism allows Wifi drivers
|
|
to notify the frequencies they are using so that other hardware
|
|
can be reconfigured to avoid harmonic conflicts.
|
|
|
|
AMD provides an ACPI based mechanism to support WBRF on platform with
|
|
appropriate underlying support.
|
|
|
|
This mechanism will only be activated on platforms that advertise a
|
|
need for it.
