wikiIntel On Demand
With the 4th Generation Intel Xeon Scalable processors, Intel introduces the Intel On Demand' Model, which allows certain additional accelerator and security features to be enabled retroactively.[1] In this way, for example, Intel Quick Assist Technology can be activated - a technology that was previously only included in individual specific processors.
Activation model
Through the Activation Model, Intel offers one-time activation of select CPU accelerators and security features:[2]
- Security Upgrade
- Intel Software Guard Extensions
- Communications & Storage Suite
- Intel Quick Assist Technology
- Intel Dynamic Load Balancer
- Intel Data Streaming Accelerator (when applicable)
- Analytics Suite
- Intel In-Memory Analytics Accelerator
- Intel Data Streaming Accelerator (when applicable)
Consumption model
In cloud environments, Intel enables as-a-service offerings for Intel On Demand via the Consumtion Model.
Linux Intel Software Defined Silicon (SDSi) driver
With Linux Kernel Version 5.18, the Intel Software Defined Silicon (SDSi) driver was included:[3][4]
- platform/x86: Add Intel Software Defined Silicon driver
- tools arch x86: Add Intel SDSi provisiong tool
