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.

Hi Miguel,
I have a question back on your request:
As we do not build those intel-speed-select too, does it still make
sense to enable it, are there other ways to control the features? Or
does it only make sense if we would build intel-speed-select as well?
Regards,
Salvatore

Hi Salvatore,
The intel-speed-select utility is a helper to configure the profiles, but
you can set it via sysfs [2] (the hard way). This user utility is found
in the kernel source code.
The plan is to ask for the integration of the intel-speed-sect utility to
Debian if it is posible (before milestone 2). But if it is not posible the
user from a Data Center can compile the tool without compiling a new kernel.
I'm learning how to add the tool to debian linux source package and after
make the request.
Also there are other Intel kernel features that will be requested for
Data Centers.
