Subject: [PATCH] tests/qemu: boot-analysis: Dump pass data times in ms, with
|
|
|
e76f14 |
diffs.
|
|
|
e76f14 |
|
|
|
e76f14 |
When (in --verbose mode) we dump the pass data, dump the times in
|
|
|
e76f14 |
milliseconds (instead of nanoseconds) so they are consistent with
|
|
|
e76f14 |
other output. Also dump the time difference from the previous event.
|
|
|
e76f14 |
|
|
|
e76f14 |
Useful for detailed debugging/analysis of problems.

(cherry picked from commit 2fd05203e461445c8053116b4276beb81b4d95d8)
