Operating Systems Linux Fedora Is Kernel module is the same as a device driver? Post 302519210 by newlinuxuser1 on Tuesday 3rd of May 2011 10:40:49 AM

Corona688, thanks for the clarification. Please correct me if I'm wrong.

Below are my assumptions:

user process->kernel->major device number(the driver)->minor device number->device

Let say I have device X and I want to know what driver(s) it uses (because it makes problems, or just out of curiosity). So how can it be done? It is really easy in Windows.

Get pointer for existing device class (struct class) in Linux kernel module

Hi all! I am trying to register a device in an existing device class, but I am having trouble getting the pointer to an existing class. I can create a class in a module, get the pointer to it and then use it to register the device with: *cl = class_create(THIS_MODULE, className);... (0 Replies)

SBP_TARG(4)						   BSD Kernel Interfaces Manual 					       SBP_TARG(4)

NAME
sbp_targ -- Serial Bus Protocol 2 (SBP-2) Target Mode devices driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device sbp_targ device firewire device scbus device targ Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5): firewire_load="YES" cam_load="YES" sbp_targ_load"YES" DESCRIPTION
The sbp_targ driver provides support for SBP-2 target mode. This driver is supposed to work with cam(4), targ(4) and firewire(4). You also need to use scsi_target(8), which can be found in /usr/share/examples/scsi_target, to provide actual devices. EXAMPLES
# mdconfig -a -t malloc -s 10m md0 # scsi_target 0:0:0 /dev/md0 (Assuming sbp_targ0 on scbus0) SEE ALSO
cam(4), firewire(4), targ(4), camcontrol(8), fwcontrol(8), kldload(8), scsi_target(8) AUTHORS
The sbp_targ driver was written by Hidetoshi Shimokawa. BUGS
This driver is currently under development. It does not work correctly in multi-initiator environments or after the bus topology has been changed. BSD
