内核启动的核心链路可概括为：引导加载程序（Bootloader）→ 加载内核映像 → 内核解压 → 内核启动 → 调用start_kernel函数 → 启动初始进程（Init Process） 1.1、启动加载程序 (Bootloader) 引导加载程序（常见的有GRUB、LILO、syslinux等）是连接硬件与内核的关键桥梁 ...

Part of the fun of working with truly large machines is that one gets to discover new scalability surprises before anybody else. So the SGI folks often have more fun than many of the rest of us. Their ...

Let’s start by revisiting what we know. We know that Solaris implements a two-layer threads model. The model defines thread abstractions at both the kernel and user layers, and user threads are ...

The kernel dispatcher and associated subsystems provide for the prioritization and scheduling of kernel threads in one of several bundled scheduling classes. The details of the implementation are ...

For most UNIX systems, Linux included, device drivers typically divide the work of processing interrupts into two parts or halves. The first part, the top half, is the familiar interrupt handler, ...

Make a system call now, get the result later: a proposed kernel patch expands the possibilities for asynchronous I/O. The kernel’s support for asynchronous I/O is incomplete, and it always has been.

Express Logic, renowned provider of advanced run-time solution for deeply embedded applications, recently added Kernel-Aware Debug Support for ARM DS-5 Development Tools in order to provide greater ...
