[PATCH v2 0/7] drm/i915/perf: add OA interrupt support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I'm resending this series to enable the OA unit with a change on patch
2 (as pointed by Matt in the previous iteration).

I've also prepared a gputop change for this in the hope that it is
enough as an open source user [1]. This other opensource user of this
change will be metrics-discovery [2] and ultimately GPA & vTune
(although those applications are not opensource).

Finally the IGT tests added for this are available on the list [3].

Cheers,
