Re: How to check if my kernel driver is leaking memory

Hi,

I am developing a kernel driver. What should I test to make sure my kernel driver is not leaking memory? 1. under normal operation (when applications open and close my driver properly) 2. in error situation (when application open my driver and then it crashes without close my driver property)

How can I find out the memory usage used by my driver? so that I can monitor it over time.

I have earlier come across a similar situation and kmemleak was very helpful. I documented my steps and you may find it useful: http://psankar.blogspot.in/2010/11/detecting-memory-leaks-in-kernel.html -- Sankar P http://psankar.blogspot.com
