Linux boss Linus Torvalds merged earlier right now a quantity of important patches for Intel CPU usually associated to efficiency states (P-states) on Linux.
Definitely one Of these Consists of a repair for a currently found Intel Turbo Increase Max Know-how (ITMT) drawback that was stopping the Alder Lake processors from performing to their fullest all by way of an overclocked state. This bug Might be very Harking again to the current Ryzen CPPC2 bug on House windows 11 As a Outcome of It is associated to process dealing with and quickest core prioritization. You will Have The power to study Regarding the ITMT problem in A lot extra element right here.
The mannequin new merged patch incorporates repaires For 3 factors collectively with One which repaires the ITMT problem with The assist of Hardware-Managed P-States (HWP). The completely different factors are associated to hibernation. The patch description is given under. The ITMT bug has been bolded.
These tackle three factors Inside the intel_pstate driver and repair two factors associated to hibernation.
Specifics:
– Make intel_pstate work appropriately on Ice Lake server methods with out-of-band efficiency administration enabled (Adamos Ttofari).
– Fix EPP dealing with in intel_pstate all by way of CPU offline and on-line Inside the lively mode (Rafael Wysocki).
– Make intel_pstate assist ITMT on uneven methods with overclocking enabled (Srinivas Pandruvada).
– Fix hibernation picture saving when using the consumer space interface based mostly on the snapshot particular system file (Evan Inexperienced).
– Make the hibernation code launch the snapshot block system using The identical mode that was used when buying it (Thomas Zeitlhofer)
That might not The one Linux bug that Alder Lake possessed. Tright here’s additionally an current Cluster Scheduler function problem That is inflicting An monumental efficiency downgrade on Linux 5.16 As in contrast with earlier kernels.
