HARDWARE --
Linux 5.12 is bringing the initial infrastructure around ACPI Platform Profile support and with this kernel it's implemented for newer Lenovo ThinkPad and IdeaPad laptops. The support allow for altering the system's power/performance characteristics depending upon your desire for a speedy, quiet, or cool experience. With Linux 5.13 it looks like HP laptops with this capability will begin to see working Platform Profile support too.

Lenovo is the initial Linux user/supporter of this Platform Profile support while Dell has also expressed interest in supporting it on Linux for letting users manipulate their desire desired balance of performance vs. cool/quiet operation. There has been an HP patch implementing the support and it's looking like that is now ready to be queued into the x86 platform driver tree once the current Linux 5.12 merge window is over, which would mark it as material for 5.13.

The patch allows for switching between cool, balanced, and performance thermal profiles on newer HP laptops supporting this ACPI Platform Profile functionality. The Linux 5.13 kernel in turn will be out this summer.
