--- Comment #4 from Lionel Landwerlin <lionel.g.landwerlin at linux.intel.com> ---
Just letting you know that letting userspace directly change this configuration
through LRI might corrupt the data coming from the OA unit.
I think Chris' patchset to set the userspace control this through a context
ioctl is the best solution. That way we can do something sensible in the kernel
when the OA unit is enabled.
