Hi,
I tried using the SysRq hotkey sequence on a serial console -
3.11.0-5-powerpc-e500mc system, by issuing a " break " and the system
immediately wedges after displaying "SysRQ : HELP : " using both "Putty"
and "Teraterm" terminal emulators. I know the system is dead because my

This provides a basic interface between hv_24x7 and perf. Similar to
the one provided for gpci, it lacks transaction support and does not
list any events.

This provides a basic link between perf and hv_gpci. Notably, it does
not yet support transactions and does not list any events (they can
still be manually composed).

24x7 (also called hv_24x7 or H_24X7) is an interface to obtain
performance counters from the hypervisor. These counters do not have a
fixed format/possition and are instead documented in a "24x7 Catalog",
which is provided by the hypervisor (that interface is also documented
in this header).
This
"H_GetPerformanceCounterInfo" (refered to as hv_gpci or just gpci from
here on) is an interface to retrieve specific performance counters and
other data from the hypervisor. All outputs have a fixed format (and
are represented as structs in this patch).

These patches add basic pmus for 2 powerpc hypervisor interfaces to obtain
performance counters: gpci ("get performance counter info") and 24x7.
The counters supplied by these interfaces are continually counting and never
need to be (and cannot be) disabled or enabled. They additionally do not

Hi Nicolas,
You will have to include the below patch with yours. You
could squash the two I guess, I have added the changelog
just for clarity. And you also might want to change the subject to
cpuidle/powernv. It gives a better picture.
Thanks
