DS-5: Install gator.ko error: unknown symbol

Note: This was originally posted on 29th August 2013 at http://forums.arm.com

Hi all,

I tried to install gator.ko compiled from the latest version of DS-5 v5.15 on galaxy tab 10.1, but it failed. My host machine runs win8 and the target device is galaxy tab 10.1 wifi with cm 10.1. (which I compiled following the instructions listed here http://wiki.cyanogen...uild_for_p4wifi ) However, when I tried to install gator.ko on galaxy tab 10.1 using "insmod gator.ko", the following error appears:

the following error: init_module '/sdcard/gator.ko' failed (No such file or directory)

Then I entered dmesg command in the terminal and the error message is as follows:

gator: Unknown symbol perf_event_release_kernel (err 0)
gator: Unknown symbol perf_event_create_kernel_counter (err 0)

But as I read the kernel code of galaxy tab 10.1 (p4wifi), I could find the corresponding definition of these two functions and they have already been exported by macros such as EXPORT_SYMBOL_GPL. Could anyone help me? Thank you!
