Bug Description
This is a public version of https:/
Backport cpufreq: intel_pstate: Enable HWP IO boost for all servers [upstream 1f5e62f5fb217f2
[Impact]
Currently there is a CPU model check for Skylake desktop and server along with the ACPI PM profile for performance and enterprise servers to enable IO boost. Patch removes the CPU model check, so that all current server models enable HWP IO boost by default.
The HWP IO boost results in improvements for IO performance on both Ice Lake and Sapphire Rapid servers.

[Fix]
Upstream patch:
cpufreq: intel_pstate: Enable HWP IO boost for all servers 1f5e62f5fb217f2
was merged to fix this. This will be back porting it to jammy.
[Test Plan]
I have tested this code, as has Intel.
[Where problems could occur]
The risk for regression is low. The change is fairly narrow, and has been upstreamed for some time.

This bug is awaiting verification that the linux/5. 15.0-102. 112 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification- needed- jammy-linux' to 'verification- done-jammy- linux'. If the problem still exists, change the tag 'verification- needed- jammy-linux' to 'verification- failed- jammy-linux' .
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
See https:/ /wiki.ubuntu. com/Testing/ EnableProposed for documentation how to enable and use -proposed. Thank you!
