Error while inserting ecryptfs module

[KrishnaPrasadBV]

Hi,
I was able to install KGPU framework. But when I tried using insmod ./ecryptfs.ko, it always gives an error -1 Device busy. I tried to trace the insertion through strace, the ecryptfs fails in __init_module as EBUSY is returned. I also checked dmesg output, it indicates Failed to register File System.
I am on Ubuntu 11.04 2.6.39.4. What may be going wrong?

Not quite sure about Ubuntu 11.04, but did you checked with lsmod whether the system's default ecryptfs module was already been loaded? Then please rmmod ecryptfs to remove it. And if you are using any encrypted folder feature on Ubuntu, then you may have to umount it to remove the ecryptfs module.

Hi,

I checked lsmod, and the ecryptfs module was not loaded.

Can you try 'sudo modprobe ecryptfs' to load the system's default ecryptfs, see what happens?

Hi,
I tried 'sudo modprobe ecryptfs', it did not give any error. So, I tried creating private directory using ecryptfs, and it is working fine. Also, I had a doubt, to add a new module, what are the steps to be followed? Should the .cu files also be compiled to kernel modules for the new program?

Hi,
I could not load ecryptfs module, but I was able to load the test module, and use callgpu, and other kernel modules. I wanted to pass some parameters to the code running on GPU, and I do not know how to pass them. I was checking the kgpu_map_page() function? Is this the one to be used, to pass parameters? Can you tell me how to go about it?
