LINUX DEVICE DRIVERS - Training at Bangalore   LINUX DEVICE DRIVERS - Training at Bangalore      Prerequisites :  ·                                 Knowledge in Linux OS  Course Goals :  People new to Linux often hear that it has excellent support for all kinds of cards and that the device drivers are stable and fast. Sometimes, though, setting up devices under Linux is often not all plug-and-play. Below we try to demystify Linux device drivers, with the aim of smoothing device selection during installs. Many modern operating systems have a method for installing special files to make hardware work. On the Apple Mac, for instance, the drivers for the hardware devices are usually special files that go in the System Extensions folder. Linux also has special files that it uses to control the hardware. Linux device drivers work through special kernel code that directly accesses the hardware. To make the services that the card or other device offers available to normal user programs, the kernel uses the special files in /dev One end of the file in /dev can be opened normally and the other end is attached to the kernel. That is of course an oversimplification, but I think you get the general idea: hardware, kernel, special file, user program and the same path back from user program to hardware. There are two forms of the kernel portion of this equation: compiled-in drivers that are coded in permanently when the kernel is built, and modules. This course is designed for starters on Device Drivers on Linux Platform,  Course Content :   Introduction - Linux & Device drivers    Overview of Linux system    The Kernel and what it does    User Space Vs Kernel Space    User Process    User view of devices    The Role of a device driver    Major and Minor device number    Making a device file    Classes of devices and modules   Linux code development           vi, the Unix Visual Editor at a Glance          C Compiler Identifying File Types using Filename C           Command Line Flags           Using 'make'   How Loadable Modules Work Benefits of loadable modules Loadable device drivers Correct use of insmod, modprobe, rmmod, and lsmod Passing parameters to a loadable module    Module Mechanics Identifying important header files Writing a simple module Compiling modules Loading/unloading modules Exporting symbols from a loadable module Creating stacked loadable modules The /proc File System    Character Drivers Typical Character Drivers Creating device files with mknod Registering character device file Listing character device driver methods Character Device Special File and Device Numbers file_operations structure struct file, struct inode Character Device Methods open(), release(), read(), write() Data Transfers between User Process and Driver copy_from_user(), copy_to_user() Kernel Memory Character Driver Example   IOCTLs           What is ioctl           Using ioctl commands to interact with a device           Implementing IOCTL in drivers   Tracing and Debugging printk for debugging Device information in /proc strace to track system calls ksyms Debugger  gdb   Blocking and Wait Queues         Blocking and Non Blocking Operations           Wait Queues, sleep & wake up           Schedule   Time Flow Time intervals in the kernel  Knowing current time  Delaying execution Utilizing Kernel Timers, Wait queues, and Task Queues   Memory Management Accessing Memory Get Some Space (kmalloc()) Get Some Pages (get_free_page()) Get Some Virtual Memory Get Some Boot-time Space   Hardware Mangement  interrupts I/O ports and I/O Memory IRQs Functions used for reading and writing I/O ports   Interrupt Management Handling and Registration Enabling and Disabling Interrupts Splitting Interrupt Handling - Top Half & Bottom Half Combating Race Conditions - Spinlocks Restrictions of kernel code running in an interrupt context   Block Device Drivers Block Device Driver Characteristics Similarities to Character Drivers Differences between Block and Character Drivers Registering block drivers The block_device_operations structure   Network Drivers Network Driver Characteristics netdevice structure fields netdevice structure methods Opening and Closing Packet Transmission Packet Reception The Interrupt handler Socket buffer   A.   Case Study: Parallel port Printer device driver Understanding the parallel port Preparing the parallel port Implementing interrupt handler for parallel port Tasklets and bottom half processing Race conditions and spinlocks Implementing read/write    Fecilities : ·                                 State of the art Lab facilities ·                                 Special  session by professionals from the Industry ·                                 Employment oriented curriculum ·                                 Small size batch ·                                 Unlimited lab timings ·                                 PG Accomdations will be provided to outstation candidates ·                                 placement assisatance can be provided to Project trainees and H1B / B1 Visa Holders ·                                 Assured placement opportunities ·                                 Flexible timing ·                                 Realtime projects   Please contact Mr Prashanth for Registrations   Regards Prashanth - overseas placement consultant   training4it   Ph : 98454 05119 E-mail : training4it@...
