New Linux Patches To Help Ensure Intel Xeon Servers Can Achieve Highest Frequencies
A set of patches for the Linux kernel's Intel P-State driver aim to ensure Intel Xeon servers can hit their highest clock frequencies following changes in the server's performance profile
It turns out some special handling is needed to update the highest frequencies of a CPU after boot to ensure the performance profile is properly reflected. The patches aim to deal with the performance profile being changed by Intel Xeon servers such as via the BMC or via Speed Select Technology to ensure that the highest frequency is properly propagated into the Linux kernel's Intel P-State CPU frequency scaling driver. These changes can be initiated by switching to different performance profiles using the Intel Speed Select Technology interface.
