The result of "__entry->walt_avg = (__entry->demand << 10)" will exceed the range of "unsigned int", which will be truncated and make the trace looks like as follows: UnityMain-4588 [004] 6029.645672: walt_update_history: 4588(UnityMain): runtime 9928307 samples 1 event 4 demand 9928307 walt 157 pelt 870 (hist: 9928307 9604307 8440077 87392 34144328) cpu 4 UnityMain-4588 [004] 6029.653658: walt_update_history: 4588(UnityMain): runtime 10000000 samples 1 event 4 demand 10000000 walt 165 pelt 886 (hist: 10000000 9955691 6549308 64000 34144328) cpu 4 Fix this by using a u64 type instead of unsgined int type and make the trace as below: UnityMain-4617 [004] 117.613558: walt_update_history: 4617(UnityMain): runtime 5770597 samples 1 event 4 demand 7038739 walt 720 pelt 680 (hist: 5770597 |
