Phoronix: Intel Arrow Lake Sound Support Ready For Linux 6.8

Along with all of the other ongoing Intel Arrow Lake processor/platform enablement, the upcoming Linux 6.8 kernel will have the sound driver support ready for landing...

Is Arrow Lake free from MS Pluton?

"These 15th Gen CPUs will make use of the new Intel 20A processor, potentially feature more cores, and reportedly sport both single and multi-core performance improvements.

probably mean "manufacturing process" and "featuring"

Intel has refused to adopt Pluton, as they already have their own security hardware solution and incorporating Pluton into their future CPU products would incur significant cost and delays. AMD has fully adopted it, but it can be disabled, if the system firmware is configured to allow that.

AFAIK there is no way to verify that it actually is disabled even if the uefi says so.

According to leaked slides about Lunar Lake Intel is supposedly planning to implement Microsoft Pluton as part of the "Intel Partner Security Engine (PSE)".

PSE is Intel's own solution that is Pluton-compatible and based on the Pluton concept and standard designed by Microsoft. The Pluton security platform is both hardware built into CPUs and control software that is loaded upon boot. Intel chose not to integrate Microsoft's Pluton Security CPU design because they wanted to design their own security hardware to put into future Intel CPU designs.

How does that differ from what Qualcomm and AMD have done? Everywhere in Microsoft Pluton documentation it says "built by silicon partners". I haven't found any mention of Microsoft actually designing the AMD hardware implementation, for example.

AMD is well known to license pretty much every part of their CPUs apart from the actual x86 parts.

Even Intel implements Arm and RISC-V into their security and management systems

Exactly, there's no way to verify that the components are actually disabled.
They also make up a large part of the boot process, so they're likely still used to some extent.
