目前,Windows 和 Linux 等操作系统无法直接从固件读取 CPU 的加速频率信息,只能依赖 CPPC(Collaborative Processor Performance Control)提供的抽象性能数值,通过线性插值方法来估算加速行为 ...
IT之家 4 月 26 日消息,在即将结束的 Linux 7.1 内核合并窗口期中,LoongArch 架构支持迎来一系列更新,获得多项底层能力增强。 根据提交内容,Linux 7.1 已能够更准确地展示并处理龙芯 CPU 漏洞信息,同时为 BPF JIT 引入更多原子指令支持,并扩展了 BPF 跳板(trampoline)的功能特性。此外,还包括缓存维护、系统调用路径及日志等方面的多项优化与修复 ...
我是hp unix 上面这些命令都不行,top只能看到25个cpu,显示不全,实际有32个cpu。 我想查看cpu个数,及32个cpu的负载均衡,怎么看? 就是想简单评估一下机器性能。
IT之家 4 月 15 日消息,科技媒体 phoronix 今天(4 月 15 日)发布博文,报道称在 Linux 7.1 内核开发迎来重要里程碑,Linus Torvalds 正式启动移除 Intel 486 CPU 支持的进程。此次更新标志着 Linux 内核正式放弃对这一经典架构的官方支持,技术重心全面转向现代硬件平台。
【本文由小黑盒作者@北十九道街于05月10日发布,转载请标明出处!】 盒友们,你有没有想过一个问题:CPU那个“最高加速频率”到底准不准?比如标称5.0GHz,实际上每个核心能跑到的上限其实不一样,但操作系统只能猜个大概。
The company will unveil its top-end Unix server Thursday, marking Big Blue's departure from the industry's assumption that more processors makes a better computer. Stephen Shankland worked at CNET ...
The release of the Steam Deck is only a few months away, and AMD is working to ensure the portable's Ryzen CPU shines bright. In light of this, an AMD developer has revealed that these efforts include ...
快科技5月6日消息,AMD已向Linux内核提交了一套全新的驱动补丁,旨在提前适配ACPI 6.7规范中即将引入的CPPC HighestFreq寄存器,以解决当前CPU频率计算长期依赖数学插值所导致的精度误差问题。 新引入的CPPC HighestFreq寄存器将在ACPI 6.7规范中被标准化,允许固件直接向操作系统交付真实的本征最高频率。 此方案无需再进行数学估算,而是直接读取CPU在当前工 ...
快科技5月8日消息,根据Linux内核上游仓库提交的最新补丁信息,服役满30年的AMD首款自研CPU K5,将被Linux主线内核正式终止支持,彻底迎来退役。 AMD ...
In brief: No one really knows when you'll be able to get your hands on a Steam Deck, with shipping dates slipping into the second quarter of 2022. In the meantime, Valve and AMD are working to squeeze ...
Ok i have a Dual Intel PIII 1.266Mhz cpus and i am running linux as an operating system.<BR><BR>i would like to know how can i start a process on the background and tell the process to utilize only ...
Why it matters: The Linux kernel includes an ancient trick to deal with possible incompatibilities in early ACPI implementations. Nowadays, the trick isn't needed and just makes thing worse for AMD ...
