Subject: [PATCH] powerpc/perf: Fix the threshold event selection for memory events in power10
Date: Thu,  4 Mar 2021 01:40:15 -0500	[thread overview]
Message-ID: <1614840015-1535-1-git-send-email-atrajeev@linux.vnet.ibm.com> (raw)

Memory events (mem-loads and mem-stores) currently use the threshold
event selection as issue to finish. Power10 supports issue to complete
as part of thresholding which is more appropriate for mem-loads and
mem-stores. Hence fix the event code for memory events to use issue
to complete.

Fixes: a64e697cef23 ("powerpc/perf: power10 Performance Monitoring support")
