Hi,

Thanks for your comment.

> How does this look in practice?

It works on a x86 machine is shown below:

# find /sys/devices/system/cpu/cpu0/hwpf/
/sys/devices/system/cpu/cpu0/hwpf/
/sys/devices/system/cpu/cpu0/hwpf/l2
/sys/devices/system/cpu/cpu0/hwpf/l2/enable
/sys/devices/system/cpu/cpu0/hwpf/l1
/sys/devices/system/cpu/cpu0/hwpf/l1/enable

There is no specific reason for directory names. We named it "l*"
because it is related to a certain cache level. We would change it,
if there is another suitable name.

Sorry, that's our mistake. The "strong" is correct.
