Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Avoid grouping events especially in cases where the kernel's PMU
driver fails to not open the events, causing the events to report back
as "<not counted>".

This update comes from:
https://github.com/intel/perfmon/pull/94

Fixes issues reported with patch:
https://lore.kernel.org/lkml/20230719001836.198363-3-irogers@xxxxxxxxxx/
