AMD’s crusty Linux CPU driver is getting an update ahead of Steam Deck

The discharge of the Steam Deck is only some months away, and AMD is working to make sure the transportable’s Ryzen CPU shines vivid. In gentle of this, an AMD developer has revealed that these efforts embody changing the processor’s ageing ACPI Linux driver to resolve Proton associated points.

Through the latest X.Org Builders Convention, AMD’s software program engineer, Ray Huang shared the corporate’s plans to switch its Linux ACPI CPUFreq driver used on all Intel and AMD processors. The developer additionally disclosed that the driving force isn’t at the moment taking part in good with video games utilizing Valve’s Proton compatibility layer, which may show detrimental to the Steam Deck’s stability. Naturally, that is one thing that AMD and Valve need to keep away from, because it may hamper the Steam Deck’s means to offer a seamless transportable gaming PC expertise.

It’s price mentioning that the CPUFreq driver has been round for the reason that daybreak of Intel’s Core CPU line, so it’s straightforward to see why it’s struggling to maintain up in 2021. Basically, the primitive software program element isn’t capable of absolutely embrace the skills of AMD’s Ryzen CPU, which ends up in lower than fascinating efficiency and energy effectivity.

Fortunately, AMD’s new CPPC driver already goes above and past its predecessor. In preliminary exams, the brand new utility has apparently boosted the efficiency of the Ryzen 7 by 10-25%. The driving force additionally retains idle core clock speeds at 400mhz when Horizon Zero Dawn is locked at 60fps on a Ryzen 7 Professional. This can be a vital enchancment over AMD’s previous ACPI element, which was solely capable of maintain the identical cores at 3.8GHz.

AMD’s shiny new CPU software program continues to be early in growth, which means there’s no launch date simply but. The corporate says it’s at the moment engaged on integrating the driving force into the official Linux kernel, so we’ll want to attend and see whether or not it’ll be prepared in time for the Steam Deck’s arrival
