I am out of ideas.
I have Ubuntu 13.04 as the OS and the kernel version is 3.11.0-rc7 which I
compiled myself.
sanmukh@sanmukh-laptop:/config/usb_gadget/g1/strings$ insmod --version
kmod version 9
sanmukh@sanmukh-laptop:/config/usb_gadget/g1/strings$ lsb_release -a
No LSB modules are available.
HI Sanmukh,
Thank you for testing the code. Yes I am using the same file and there is no
typo. When I insert the module it inserts just fine.
In this case mystring takes the default value "blah" as seen in log below.
dmesg:
[ 7907.858933] Demonstrating module parameters
[ 7907.858937]
I have kernel 3.11.0-rc7 and it seems to be working fine. Are you sure the
file attached is the correct one or there is no typo? See the output which
I got compiling your file and loading it as a module in the attachment.
Thanks,
Sanmukh

Hi all,
I use the kernel version "3.10.0-4" that came with Ubuntu distribution.
When I compile the example module I got from LKMPG (hello-5.c) and try to load
the driver by passing the module with the following command, it gives the
following error:
# insmod parameter.ko mystring="bebop"

Arun,
I guess, you need to select the xhci_hcd module in make menuconfig for
building it as a module. Here are the steps to do it.
Device Drivers --->
[*] USB support --->
Make sure "Support for Host-side USB" is a dynamically loadable module by
moving the cursor to that item and hitting the '
Just to explain my previous mail even better--
1. If I need to protect my driver from itself, it can add its own locking.
2. If the problem is that dcache_lock is used to protect critical
variables from other parts of the kernel, I have two options-
a) I will need to restructure my code to avoi
