I've got i.MX8 ULP processor and built Yokto Linux image for it. I need to know exact current frequency of each Cortex-A35 core so I tried to use command from chapter 6.2 of IMX_LINUX_USERS_GUIDE but nothing happens. There is no any directory like that: Spoiler It seems ...
I can't get cpu frequency on imx8mm with /proc/cpuinfo etc. How do i get it? ■conditionsBSP = i.MX Linux Yocto Project BSP 6.1.55_2.2.0image = image based core-image-full-cmdline-imx8mm-lpddr4-evkhardware = custom board with imx8mm ■log(cpu info) root@XXX:~# cpufreq-info cpu...
This chapter is a basic tour of the kernel-provided device infrastructure in a functioning Linux system. 本章是对Linux系统中内核提供的设备基础架构的基本介绍。 Throughout the history of Linux, there have been many changes to how the kernel presents devices to the user. We’ll begin by lookin...
To provide a uniform view for attached devices based on their actual hardware attributes, the Linux kernel offers the sysfs interface through a system of files and directories. The base path for devices is /sys/devices. For example, the SATA hard disk at /dev/sda might have the following pa...
hi, is there a way to know the current operating frequency of cpu cores on a linux ? processor model: Intel(R) Xeon(R) CPU X5650 do let me know if there any tool which i can use to find out core speeds and core temperatures. Translate...
https://superuser.com/questions/406141/how-to-get-an-arm-cpu-clock-speed-in-linux 结论: 从分析来看,频率信息可能是在SOC其他部分提供的,不是有cpuinfo所提供,幸运的话可以通过计算估计得到frequency。 (3)查看内存信息 cat/proc/meminfo (4)查看存型号、频率,使用命令(使用root才行) ...
If you cannot disable CPU scaling through the system BIOS, you can limit the impact of CPU scaling by disabling the scaling through the Linux kernel or setting the CPU frequency governor to always run the CPU at full speed. Some Linux systems, however, don't have a governor to configure ...
I would like to increase CPU freq up to maximum 1.5 GHz by analogy with:https://e2e.ti.com/support/processors-group/processors/f/processors-forum/982794/am5728-how-to-modify-cpu-freq-for-linux-rt Like I understood I can do it through U-boot. I should change this one...
Note: A tick(cycle) is the time it takes to send a single pulse. A pulse consists of a high voltage followed by a low voltage. There can be billions of ticks per second depending on the frequency(GHz) of the CPU clock. You can get the number of CPU ticks since boot from /proc/...
For a common virtualization cluster, where you want to provide a lot of cores to run as many virtual machines as possible, you might choose a lower clock frequency and more cores per CPU and a second CPU socket on your mainboard instead. ...
