How does this look in practice?
# ls /sys/devices/system/cpu/cpu0/hwpf/
l0
l1
l2
...
?
Dumb question, but why don't we give these things names? If the Intel
one is called "L2 Hardware Prefetcher Disable", couldn't the directory
be "l2_prefetch"?
BTW, your "reliable" is mismatched with the "strong" value in the docs.
