Compilation under 4.4.26 kernel #4

Hi,

I have successfully compiled the memguard as a kernel module without any error, but When I am loading it my system crashes and I have to hard reboot the system by removing power supply.

Kindly help me out regarding this issue it is really very important for me.

Thank in advance.

Hi, Two comments:

Try 'devel' branch.
use different performance counter. The default is PERF_COUNT_HW_CACHE_MISSES, which is not the llc miss counter in ARM AFAIK.

Hi, I have tried as suggest by you, memguard loads properly. But it seems that it is not working as expected, memguard isn't regulating the memory bandwidth.

Processor is Intel(R) Atom(TM) x5-Z8350 CPU @ 1.44GHz

What might be the issue.

Thanks in advance.
