| Subject: powerpc/perf: Fix the threshold event selection for memory events in |
| power10 |
| |
| From: Athira Rajeev <atrajeev@linux.vnet.ibm.com> |
| |
| [ Upstream commit 66d9b7492887d34c711bc05b36c22438acba51b4 ] |
| |
| 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. |
