Hi, Here is what I am proposing, in reply to all your comments: 1) rename the events to match Thomas's proposal: power:power_cpu_cstate power:power_cpu_pstate power:power_cpu_sstate ... 2) introduce a new Kconfig option CONFIG_DEPRECATED_POWER_EVENTS and conditionally map a subset of the new events to the old ones for backward compatibility with the existing user apps. The apps should be converted to the new API asap, 3) update documentation Other remarks here below: On Wed, Sep 22, 2010 at 8:49 PM, Rafael J.

The ACPI code is not using the SSTATE event. Indeed inserting a tracepoint at kernel/power/suspend.c:suspend_enter() is more generic. I will correct this. > Moreover, why is the cpu argument necessary for POWER_SSTATE at all? The cpu_id parameter is present in all events prototypes. This is not needed.
