Phoronix: AMD Posts New Linux Patches Enabling Dynamic Boost Control

A new patch series from AMD today for the Linux kernel enables Dynamic Boost Control support that can be found with some Ryzen SoCs for tuning the processor for optimal performance...

Doesn’t the kernel require an open source application that can use it to add new device drivers?

There is a Python script as part of the patches that exercises the new ioctls, which tends to be good enough for upstreaming kernel standards.

Errr, stupid question: does a 7950x count as a "SOC" in this context?

It does. The package contains the cores, memory, PCIe, SPI, SATA, and USB controllers. You could easily build a system without a chipset. The chipset(x570 for instance is the zen2 IO die btw) is a PCIe peripheral that basically is the combination of a PCIe multiplexer combined with other controllers for extra connectivity.

Great. More hardware features that are only available to proprietary userspace blobs, hidden behind an equivalent of DRM.

So basic performance setting for the normal desktop CPUs are now implemented by talking to a secure element? Dislike.

What about EPYC? Does it have the same mechanism?

I guess they did that to avoid Plundervolt on AMD CPUs

To hell with this proper open source friendly software!

i demand closed source, anti-FOSS proprietary binary crap coded by Dear Leader Jensen himself!

/S in case that somehow its needed.

will it work on zen2 laptop ?
