| |
The HWP IO boost results in slight improvements for IO performance on both Ice Lake and Sapphire Rapid servers.
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.
Remove the CPU model check, so that all current server models enable HWP IO boost by default.
