5 | Subject: [PATCH 1/1] cyclictest: finish removal of 1 second first loops | ||
6 | |||
7 | Observation: | ||
8 | Huge latencies reported close to 1 second when certain options | ||
9 | are used in cyclictest. | ||
10 | |||
11 | Problem: | ||
12 | [ commit da4956cbcaf7945554f30e4d3a9be09b1431b19a | ||
13 | use interval on first loop instead of 1 second ] | ||
14 | removed the 1 second first timing loop out of the main path | ||
15 | in cyclictest but left it in two other paths, namely the ones | ||
16 | triggered by these two options: | ||
17 | -r --relative use relative timer instead of absolute | ||
18 | -s --system use sys_nanosleep and sys_setitimer | ||
19 | This causes huge latencies of close to 1 second to be reported | ||
20 | by cyclictest with certain uses of those two options. | ||
21 | |||
22 | Fix: | ||
23 | Extend the original commit to remove the 1 second hardcoded | ||
24 | timer values from the RELTIME and ITIMER options. Use the | ||
25 | the actual interval instead. | ||
26 | |||
27 | Upstream-Status: Accepted | ||
