1. Introduction to Linux device driver 潘仁義

2. The role of device driver Flexible Mechanism? Policy? 只提供存取硬體的能力，而不加諸任何限制 介於『應用程式』與『硬體裝置』的軟體層 功能性 ? 簡潔性 ?

3. Splitting the Kernel

4. Classes of devices and modules Character device Can be accessed as a stream of bytes open, close, read, write /dev/console Block device Can host a filesystem and transfer any number of bytes at a time mount a filesystem Network interface Can exchange data with other hosts packet transmission

5. Kernel compile and installation Version 2.4.10 above Kernel source http://www.kernel.org/ Make kernel cd /usr/src/linux make clean make menuconfig make dep; make bzImage make modules; make modules_install cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.24 cp.config /boot/config-2.4.24 cp System.map /boot/System.map.2.4.24 lilo; reboot; dmesg

6. /usr/src/linux directory kernel/ 除了 fs, mm, networking 外的核心碼 fs/ File system mm/ Memory management net/ Socket library, Protocol stack ipc/ and lib/ Include/ and arch/ driver/ driver/char, driver/block, driver/net
