strongly recommend that you enable this option for notebook users. Chipset (chipset): the chipset here mainly configures the nanqiao chip. But here we often adjust only the second item, initiate graphic adapter, which means what graphics card starts in Chinese. That is to say, when a PCI video card and a PCI-e video card exist in our computer, let the video card work to guide the system. In general, the adjustment here in the integrated motherboard is PCI-E/on board, that is, the first from th

electrical signals at a variable frequency as the interrupt source of clock interruption.Programmable interval timer (PIT) The Programmable Interval Timer PIT specifies a fixed frequency within the core and issues a special interrupt, namely, the clock interrupt (timer interrupt ). When Linux is started, it will program the first PIT in the PC to interrupt the clock at a certain frequency. The interval between the two interrupts is called a tick ).CPU local Timer The local

functions except for the content related to the multi-processor configuration. If acpi = off is normal, but acpi = ht is abnormal, There is a bug in the Code for parsing the ACPI table or Linux SMP. Pci = noacpiDo not use ACPI to process any PCI-related content, including enumerative PCI root bus and PCI device interruption routing. Acpi = noirqDo not use ACPI to handle PCI device interruption routing. The difference from pci = noacpi is that it allows the use of ACPI to enumerate PCI root bus.

This article describes how to use the system preparation tool (sysprep) to automatically implement the successful deployment of Microsoft Windows XP. Sysprep is a tool designed for system administrators, OEMs, and others who must automatically deploy Windows XP operating systems on multiple computers. After performing the initial installation steps on a computer, you can run the sysprep tool to prepare the demo computer for cloning. Requirements for running the sysprep ToolTo use the sysprep too

I. Overview Objective Kernel How to manage hardware devices: polling, interrupts. Interrupt efficiency is high and the response is faster than polling because it takes advantage of the ' interrupt signal cycle polling ' that is done before the hardware itself executes the instruction. Classification Interrupts are divided into synchronous (synchronous) and asynchronous (asynchronous).Synchronization is also known as an exception, generated by a CPU instruction error,

/proc provide the latest information about the physical environment of the system. Although the files in/proc are virtual, they can still be viewed using any file editor or a program like ' more ' or ' less ' or ' cat '. When the editor tries to open a virtual file, the file is created from a thin air (on the fly) through the information in the kernel. Here are some interesting results I got from my system: $ ls-l/proc/cpuinfo-r--r--r--1 root root 0 Dec 11:01/proc/cpuinfo$ file/proc/cpuinfo/proc

interrupt controller, allowing the CPU to read this vector over the data bus.C, send the trigger signal to the processor's INTR pin, which generates an interrupt.D, wait until the CPU confirms it by writing the interrupt signal into an I/O port of the programmable interrupt controller, and when this happens, clear the Intr line.3, return to the 1th step.You can modify the mapping between the IRQ and the vector by releasing the appropriate instructions on the interrupt controller port.You can se

:ide1......However, the Intel x86 platform generally uses a technology called Memory Mapping (MMIO), which is part of the PCI specification, the IO device port is mapped to memory space, and after mapping, the CPU accesses the IO port as if it were accessing memory.

In fact, our optimization method is also to the eth1 interrupt request evenly distributed on each CPU, from the beginning of Linux 2.4 to implement the IRQ binding on a certain CPU or some CPU, called multiple CPU interrupt affinity. To achieve this, there are several conditions: 1. eth1 corresponding interrupt controller must be IO-APIC chip, sometimes hardware support, but Io-

When other devices are added or removed, the PCI address of the KVM virtual machine remains unchanged. Virt x2apic X2apic reduces the resource overhead of APIC access and improves client performance.
