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
Regards

Hi Greg !
You didn't say if that explanation was to your liking :-)
If it is, do you want Aneesh to re-submit the
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

bin_attributes created/updated in create_files() (such as those listed
via (struct device).attribute_groups) were not placed under the
specified group, and instead appeared in the base kobj directory.
Fix this by making bin_attributes use creating code similar to normal
attributes.

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).

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).

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

Does it conflict with anything currently in linux-next (the linux-next
branch
of linux-pm.git in particular)?
Hi Rafael,
I applied this to your linux-next branch successfully . No conflicts
found.
Good. :-)
Please feel free to add my ACK to it.
Thanks very much!
