Issue #642 has been updated by Patrick Rudolph.
Nehalem and older doesn't use the `intel_pstate` driver, but only `acpi-cpufreq`. Thus _CST generation is important for such older platforms. ---------------------------------------- Bug #642: x201t Turbo boost not working, CPU running hot https://ticket.coreboot.org/issues/642#change-2274 * Author: Janez Novak * Status: New * Priority: Normal * Category: chipset configuration * Target version: main * Start date: 2026-05-03 * Affected versions: main * Affected hardware: Lenovo X201 Tablet * Affected OS: All ---------------------------------------- Hello, i installed Coreboot on my x201t but turbo boost isn’t working and cpu won’t go past 2.1 GHz. My processor is an i7 640LM.
