cpufreq: add virtual-cpufreq driverIntroduce a virtualized cpufreq driver for guest kernels to improveperformance and power of workloads within VMs.This driver does two main things:1. Sends the frequency of vCPUs as a hint to the host. The host uses thehint to schedule the vCPU threads and decide physical CPU frequency.2. If a VM does not support a virtualized FIE(like AMUs), it queries thehost CPU frequency by reading a MMIO region of a virtual cpufreq deviceto update the guest's frequency scaling factor periodically. This enablesaccurate Per-Entity Load Tracking for tasks running in the guest.Co-developed-by: Saravana Kannan Signed-off-by: Saravana Kannan Signed-off-by: David Dai Signed-off-by: Viresh Kumar List of files: /linux/drivers/cpufreq/Makefile

cf8e8658100d4eae80ce9b21f7a81cb024dd5057 - arch: Remove Itanium (IA-64) architecture

Thu, 20 Oct 2022 15:54:33 +0200

arch: Remove Itanium (IA-64) architectureThe Itanium architecture is obsolete, and an informal survey [0] revealsthat any residual use of Itanium hardware in production is mostly HP-UXor OpenVMS based. The use of Linux on Itanium appears to be limited toenthusiasts that occasionally boot a fresh Linux kernel to see whetherthings are still working as intended, and perhaps to churn out somedistro packages that are rarely used in practice.None of the original companies behind Itanium still produce or supportany hardware or software for the architecture, and it is listed as'Orphaned' in the MAINTAINERS file, as apparently, none of the engineersthat contributed on behalf of those companies (nor anyone else, for thatmatter) have been willing to support or maintain the architectureupstream or even be responsible for applying the odd fix. The Intelfirmware team removed all IA-64 support from the Tianocore/EDK2reference implementation of EFI in 2018. (Itanium is the originalarchitecture for which EFI was developed, and the way Linux supports itdeviates significantly from other architectures.) Some distros, such asDebian and Gentoo, still maintain [unofficial] ia64 ports, but many havedropped support years ago.While the argument is being made [1] that there is a 'for the commongood' angle to being able to build and run existing projects such as theGrid Community Toolkit [2] on Itanium for interoperability testing, thefact remains that none of those projects are known to be deployed onLinux/ia64, and very few people actually have access to such a system inthe first place. Even if there were ways imaginable in which Linux/ia64could be put to good use today, what matters is whether anyone isactually doing that, and this does not appear to be the case.There are no emulators widely available, and so boot testing Itanium isgenerally infeasible for ordinary contributors. GCC still supports IA-64but its compile farm [3] no longer has any IA-64 machines. GLIBC wouldlike to get rid of IA-64 [4] too because it would permit some overduecode cleanups. In summary, the benefits to the ecosystem of having IA-64be part of it are mostly theoretical, whereas the maintenance overheadof keeping it supported is real.So let's rip off the band aid, and remove the IA-64 arch code entirely.This follows the timeline proposed by the Debian/ia64 maintainer [5],which removes support in a controlled manner, leaving IA-64 in a knowngood state in the most recent LTS release. Other projects will followonce the kernel support is removed.[0] https://lore.kernel.org/all/CAMj1kXFCMh_578jniKpUtx_j8ByHnt=s7S+yQ+vGbKt9ud7+kQ@mail.gmail.com/[1] https://lore.kernel.org/all/0075883c-7c51-00f5-2c2d-5119c1820410@web.de/[2] https://gridcf.org/gct-docs/latest/index.html[3] https://cfarm.tetaneutral.net/machines/list/[4] https://lore.kernel.org/all/87bkiilpc4.fsf@mid.deneb.enyo.de/[5] https://lore.kernel.org/all/ff58a3e76e5102c94bb5946d99187b358def688a.camel@physik.fu-berlin.de/Acked-by: Tony Luck Signed-off-by: Ard Biesheuvel List of files: /linux/drivers/cpufreq/Makefile

Fri, 24 Dec 2021 02:05:00 +0100

cpufreq: amd-pstate: Introduce a new AMD P-State driver to support future processorsAMD P-State is the AMD CPU performance scaling driver that introduces anew CPU frequency control mechanism on AMD Zen based CPU series in Linuxkernel. The new mechanism is based on Collaborative processorperformance control (CPPC) which is finer grain frequency managementthan legacy ACPI hardware P-States. Current AMD CPU platforms are usingthe ACPI P-states driver to manage CPU frequency and clocks withswitching only in 3 P-states. AMD P-State is to replace the ACPIP-states controls, allows a flexible, low-latency interface for theLinux kernel to directly communicate the performance hints to hardware.AMD P-State leverages the Linux kernel governors such as *schedutil*,*ondemand*, etc. to manage the performance hints which are provided by CPPChardware functionality. The first version for AMD P-State is to support oneof the Zen3 processors, and we will support more in future after we verifythe hardware and SBIOS functionalities.There are two types of hardware implementations for AMD P-State: one is fullMSR support and another is shared memory support. It can useX86_FEATURE_CPPC feature flag to distinguish the different types.Using the new AMD P-State method + kernel governors (*schedutil*,*ondemand*, ...) to manage the frequency update is the most appropriatebridge between AMD Zen based hardware processor and Linux kernel, theprocessor is able to adjust to the most efficiency frequency according tothe kernel scheduler loading.Please check the detailed CPU feature and MSR register description inProcessor Programming Reference (PPR) for AMD Family 19h Model 51h,Revision A1 Processors:https://www.amd.com/system/files/TechDocs/56569-A1-PUB.zipSigned-off-by: Huang Rui Signed-off-by: Rafael J.
