Hi Sukadev,
I'm curious about commit e0728b50d480 ("powerpc/perf: Export Power8
generic and cache events to sysfs"). This commit translates perf
high-level event names into raw codes but only on one architecture for
one CPU.
While I can see how that is useful, I'm wondering why this was implemented
as being specific to a single processor family. Should this not be done
generically for all architectures? I accept that translating event names to
raw codes for perf can be difficult but there are also tools like evt2raw
whose output can then be used with perf.

Never mind, it's obvious to me now even if only one power8 CPU is
supported.
