Intel’s payable software-upgrading CPU feature to see Spring release in Linux 5.18 support

Twitter user Andreas Schilling notes that this is not the first time Intel has attempted to block computer processors’ features behind a paywall. He notes that in 2010, Intel created a part to unlock higher clock speeds and increased memory cache for the Intel Core i3-2xxx series, also known as the Sandy Bridge family of processors.

It’s not the first time Intel is trying something like Software Defined Silicon. There was the Intel Upgrade Service in 2010 where Intel did add some higher clocks and additional cache to certain Core i3-2xxx (Sandy Bridge) SKUs.https://t.co/poCFbGT81D — Andreas Schilling (@aschilling) September 28, 2021 Schilling notes that the feature was not a success and was halted by Intel. During Schilling’s tweet, Intel was in several discussions about initiating patches to enable SDSi functionality in Linux. Last year, at this time, Linux was in version 5.15. Now that we are coming into the horizon of Linux 5.18, Intel is prepared to launch the new feature in the upcoming kernel. Hans de Goede, a seasoned Linux developer for Red Hat and several other hardware-related projects, states that “Assuming no major issues are found, the plan is to get this in before the 5.18 merge window.”

What is Intel Software Defined Silicon (SDSi)?

Intel Software Defined Silicon (SDSi) enables extra silicon elements in current and deployed server processors through the software. Intel has not divulged its future goals facilitating its paywalled CPU software-upgradable measures.

User-selected Features Capabilities

Viewing the current information about Intel’s SDSi program, it does appear to have its advantages without looking at the issue of having to pay for any features. Intel’s Xeon processors are rich in features, such as support for as much as 4.5 TB of memory per individual socket, network virtualization functionality, Intel’s Speed Select technology, as well as colossal SGX enclave size. And that is just the tip of the iceberg. Recently, the company began offering infrastructure as a service (IaaS), virtual machine density, liquid cooling, search capability, media processing, and more. With its upcoming Xeon fourth-gen scalable ‘Sapphire Rapids’ processors, Intel will offer specialized variants of its Xeon chipset, such as:

L- Large DDR Memory Support (up to 4.5TB) M- Medium DDR Memory Support (up to 2TB) N- Networking/Network Function Virtualization S- Search T- Thermal V- VM Density Value Y- Intel Speed Select Technology

Recognizing that not all users will need every option available, Intel chooses to offer specific features to their customers without adding further unusable options. Intel’s third-gen Xeon series offers 57 variations, but each provides the same amount of efficient cores, TDP, and boost clocks. The only difference between the variations is manufacture-locked features. Instead of offering a vast number of processors, all with the same capabilities—with some features locked—the company plans to create a few processors so customers can choose their attributes and not have to worry about additional unused offerings. Also, Intel can limit the amount of cost due to creating multiple versions for users. Unfortunately, from a consumer standpoint, Intel is looking at this move to create a micro transactional plan for the upcoming chips. And, customers are not happy.

The Negative Impact of Pay-As-You-Need Features

When initially announced, the Internet was already abuzz about the impact of designing hardware with microtransactions. Gamers have already experienced microtransactions in leading games, unlocking new skins, more accessibility, and more for varying prices. Creating hardware with the same concept has a similar backlash that gamers experience.

— meta (@eigenform) September 28, 2021 Outside of Intel choosing to allow consumers to pay for additional features on their chip, the negative impact it appears to be having is that the company is not disclosing a lot of information about the new process and even defending any of the backlash currently received. Intel’s new SDSi program will be available in Linux 5.18, available in Spring 2022. Sources:
