Dear Maintainer,
Intel is planing to release the next-generation Xeon products [1] and some
of the features are not enabled on Debian. It would be useful to have this
feature in Bookworm.
# Intel(R) Speed Select Technology
CONFIG_INTEL_SPEED_SELECT_INTERFACE=m
The Intel(R) Speed Select Technology (Intel(R) SST) provides a powerful
new collection of features that give more granular control over CPU
performance. With Intel(R) SST, one server can be configured for power
and performance for a variety of diverse workload requirements.
Refer to the links below for an overview of the technology:
* https://www.intel.com/content/www/us/en/architecture-and-technology/speed-select-technology-article.html
* https://builders.intel.com/docs/networkbuilders/intel-speed-select-technology-base-frequency-enhancing-performance.pdf
These capabilities are further enhanced in some of the newer generations
of server platforms where these features can be enumerated and controlled
dynamically without pre-configuring via BIOS setup options. This dynamic
configuration is done via mailbox commands to the hardware. One way to
enumerate and configure these features is by using the Intel Speed Select
utility.
