RE: printk??

[Medeiros Edward M NPRI <MedeirosEM@xxxxxxxxxxxxxxxxx>]

Hello,

 

I just wanted to add that when I install my driver using the 3 steps called out below and I look at the file "/proc/devices"  I don't see my device listed.   I am doing something wrong here.  Does anyone have any suggestions?

Thank you

Hello,

 

I just wrote a simple PCI device driver based on a char device driver that someone submitted to this website.  I have done the following to install the driver:

 

1.      insmod pci_char_driver.ko

2.      mknod /dev/pci_char_driver c 12 0

3.      chmod 664 /dev/pci_char_driver

 

When I run "lsmod" I see my driver and when I run"ls -l /dev/pci_char_driver" I see my device with the correct major and minor numbers.

The problem is that when I run "dmesg" I don't see any of the print statements I put in the "probe()" routine!   Am I looking in the right place?

Where does the output for printk go?

 

Thank you.
