    perf: Document the ABI of perf sysfs entries · 2ac3634a
    Sukadev Bhattiprolu authored
    This patchset addes two new sets of files to sysfs for POWER architecture.
    
    	- perf event config format in /sys/devices/cpu/format/event
    	- generic and POWER-specific perf events in /sys/devices/cpu/events/
    
    The format of the first file is already documented in:
    
    	sysfs-bus-event_source-devices-format
    
    Document the format of the second set of files '/sys/devices/cpu/events/*'
    which would also become part of the ABI.
    
    Changelog[v4]:
    	[Jiri Olsa]: Mention that multiple event= like terms can be specified
    	in the 'events' file.
    	[Jiri Olsa]: Remove the documentation for the 'config format' file
    	as it is already documented in 'Documentation/ABI/testing/'.
    	[Jiri Olsa]: Move ABI documentation from 'stable/' to 'testing/'
    
    Changelog[v3]:
    	[Greg KH] Include ABI documentation.
