What Hacker News says
2 sourcesThe conflict between the market wanting systems that are (a) as small and light as possible and (b) as fast as possible means that modern systems are designed to have close integration between the platform and the OS to perform appropriate thermal management. If the OS doesn't indicate that it supports doing this, the hardware will run in a much more constrained mode. Apple can do this without too much trouble since they implement the whole stack, but it's more complicated in the PC space. Intel have a spec called Dynamic Power and Thermal Framework (DPTF), but the useful part of it is the adaptive thermal policy, and Intel refuse to publicly document it.
I reverse engineered a chunk of this (https://mjg59.dreamwidth.org/54923.html) and it got merged into Intel's Thermal Daemon (https://github.com/intel/thermal_daemon) which /should/ impr

ove things, but it's complicated by this mechanism allowing for vendor-specific controls that are usually implemented by having a background service running under Windows that triggers them.
There's multiple things that can be criticised here:
1) Intel pushing OEMs to adopt a technology that they (a) don't document and (b) don't write proper Linux support for
2) Canonical not making it clear that OEM certification only requires that the system work, not that it work as well as it does under Windows
3) Dell not figuring out a decent solution for this, even for systems that they nominally support Linux on
Dell could build hardware that doesn't rely on adaptive thermal management, but that hardware would either be bigger or slower than competitors' hardware. Fixing this unilaterally is hard - we need an open spec that's implemented by both hardware vendors and integrated into mainstream Linux distributions. Given where we are, the easiest way to get there would be for Intel to publicly document DPTF.
