[Intel-gfx] [PATCH v3 0/2] Avoid reading OA reports before they land

[Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com>]

Fix OA issue seen on DG2 where parts of OA reports are zeroed out or
have stale values. This was due to the fact that rewind logic was not
being run when the tail pointer was aged. The series drops the complex
aging/aged logic and just checks the reports for validity.
