RE: [PATCH v4 0/4] cn10k DDR Performance monitor support
From: Bharat Bhushan
Date: Wed Sep 29 2021 - 05:05:13 EST
These patches are there in review for sometime now. In fact there are some more patches pending for review in "driver/perf" subsystem.
Tried reaching out Will Deacon but he seems to be not responding. Not sure who is going to review/pull these changes.
Can someone help on who is going to review and pull these (driver/perf subsystem) changes?
