设计一台“最小化”的极简电脑。 【CSDN 编者按】在大模型、AI 芯片和多核服务器不断“卷”硬件性能的时代，是否还有人愿意回到极简主义的硬件设计，去探索最小系统的可能性？本篇文章讲述了一位开发者如何用仅仅三个 8 引脚芯片，打造出一台可运行 Linux ...

在 ARM、RISC-V、PowerPC 以及大量国产化 SoC 平台中，Device Tree（设备树）已经成为 Linux BSP、驱动适配和板级 bring-up 的核心基础设施。很多系统研发工程师日常会改 DTS、排查 probe 失败、修 GPIO 和中断，但如果只停留在“会改节点”的层面，遇到 deferred probe、overlay ...

One of the last things the Linux kernel does during system boot is mount the root filesystem. The Linux kernel dictates no filesystem structure, but user space applications expect to find files with ...

Ø在 x86 系统中，将 1M 空间最上面的 0xF0000 到 0xFFFFF 这 64K 映射给 ROM。 Ø当电脑刚加电的时候，会做一些重置的工作，将 CS 设置为 0xFFFF，将 IP 设置为 0x0000，所以第一条指令就会指向 0xFFFF0，正是在 ROM 的范围内。 Ø在这里，有一个 JMP 命令会跳到 ROM 中做初始化 ...

Chinese companies have released a number of tiny devices designed to let you run Android apps on your TV over the past year or two. Some of the best models feature Rockchip RK3188 ARM Cortex-A9 ...

When the Linux Foundation announced that it was creating its own UEFI boot solution, it seemed that our woes about not being able to install Linux on Secure Boot systems would soon be coming to an end ...

Freeing the way for independent Linux distributions to be installed on Windows 8 computers, the Linux Foundation has released software that will allow Linux to work with computers running the UEFI ...

A severe vulnerability exists in almost all signed versions of GRUB2 bootloader used by most Linux systems. When properly exploited, it could allow threat actors to compromise an operating system’s ...

Linux shim, a small piece of code that many major Linux distros use during the secure boot process, has a remote code execution vulnerability in it that gives attackers a way to take complete control ...
