| Subject: perf intel-pt: Fix missing CYC processing in PSB |
| |
| From: Adrian Hunter <adrian.hunter@intel.com> |
| |
| [ Upstream commit 03fb0f859b45d1eb05c984ab4bd3bef67e45ede2 ] |
| |
| Add missing CYC packet processing when walking through PSB+. This |
| improves the accuracy of timestamps that follow PSB+, until the next |
| MTC. |
