Translating perf events to raw event codes via sysfs
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.
