PCI8系列 PCI9系列 PCI9054 linux驱动程序 PLX SDK Samples ================================================================ ABOUT This document provides a brief description of the samples included in the PLX SDK. Please refer to the source code in each sample & the PLX SDK User's Manual for additional details. The PLX samples are intended to demonstrate use of the PLX API. The samples are not intended for debug or real world applications, although they can be extended to complex applications. They should be treated as a reference for writing custom software that utilizes the PLX API. Not all samples work with all PLX devices. The PLX API supports numerous PLX chip families in PCI/PCIe, including 6000-series PCI-to-PCI bridges, 9000-series PCI-to-Local bus bridges, & 8000-series PCI/PCIe bridges & switches. Some samples are provided only for specific chip families. SAMPLES - ApiTest Simple application that calls various PLX APIs for a selected device & verifies return codes & parameters. The API calls made depend upon the type of device selected. - DSlave Demonstrates how to read/write from a PLX 9000 PCI BAR space using the PLX API/driver to perform the data transer. This operation is often referred to as "Direct Slave". - DSlave_BypassApi Similar to the 'DSlave' sample, except this sample uses the PLX API only to map a PCI BAR space directly to the application's virtual space. The application can then directly access the space via simple memory dereferencing, bypassing the PLX API/driver & resulting in greater performance, especially for small transfers. The application is responsible for initializing the BAR space, such as setup of translation/remap registers. - LocalToPciInt [9000-series & 8311] Demonstrates how to wait for a generic Local-to-PCI interrupt using the PLX Notification API. - NT_DmaTest [8000-series switches with DMA & NT support] Demonstrates using the DMA engine in a PLX 8000 switch to transfer data through a PLX

华为4G Android系统ME909S-821 Linux驱动及说明，Linux各种版本，适合各种kernel华为linux驱动集成指导

这个驱动是MT7601U无线wifi的，这个驱动的移植可以参考我的博客-MT7601U无线wifi的移植部分，他们是相匹配的(本人亲测后可用)

内包含linux2.6版本以上和以下两个版本驱动，以及脚本示例和模块相关说明资料

rfid rc522 linux驱动,功能齐全；可以读写，修改密码

Intel(R) HD Graphics在Linux下的驱动，适用于Debian/Ubuntu。

OK6410 linux混杂设备驱动LED程序，使用3.0.1内核编译，还有驱动源码、Makefile和测试程序

Qualcomm-Atheros-QCA9377-Wifi-Linux驱动，联想E42-80等等型号电脑适用，此外modprobe设置不要加载idea_thinkpad模块（该模块默认禁用wifi硬件，需自行将其加入黑名单）

linux驱动编写ppt 教程 一步一步教你编写驱动

1，本文给出了linux 下使用IIC总线读写EEPROM 的实现程序。 2, 本文给出了在编程中遇到的几种非常隐蔽的错误的解决方法。 3，本文的读写程序非常通用： i2c -d /dev/i2c-1 -s 0x51 0x05 18 -----Write 18 to the register: 0x05 of the i2c-slave address: 0x51 i2c -d /dev/i2c-10 0x57 0x05 ------Read the register: 0x05 of the i2c-slave address: 0x57 i2c 0x40 0x0f ----- 在默认路径下读 i2c 从设备地址为0x40的 0x0f的地址（或寄存器地址）
