[Intel-gfx] [PATCH] drm/i915/perf: Refactor oa object to better manage resources

[Lionel Landwerlin]

Hi Umesh,

I just noticed this different between v1 & v2.
My understanding is that if destroy() is called, stream should be the 
same as dev_priv->perf.exclusive_stream.
If it's not it sounds like a bug. So why change this?
