pm-graph v5.7 - important s2idle fixes
Important fixes:
- in s2idle, use timekeeping_freeze trace mark instead of
machine_suspend to denote entry into s2idle mode.
- in s2idle, use machine_suspend trace mark to create a new virtual
device called "s2idle_enter_<n>x". It denotes an s2idle_enter call
loop of <n> iterations where s2idle was never actually achieved.
It isn't counted as "freeze time" in the header.
- in s2idle, only show multiple freeze times if s2idle went in and
out of resume_noirq. Otherwise multiple freezes are shown with
"waking" time subtracted (waking time is time spent outside s2idle
dealing with wakeups).
- in s2idle summaries, include "FREEZEWAKE" as an issue when at
least 1ms is spent waking from s2idle. A clean run should only
wake for the rtc timer.
- add support for device callbacks with matching names in the same
phase. In rare cases some devices register multiple callbacks from
separate drivers using the same name. Without this fix only one is
shown.
- add kparamsfmt string back to fix bootgraph
General updates:
- when suspend_machine is missing, error says "failed in
suspend_machine"
- extract target count/time and add to summary title if -multi
used
- include any instances of "timeout" in dmesg as issues to be
logged.
- fix ftrace parse to handle any number of flags (instead of
just 4).
- remove sync/async_device string from device detail, remains in
hover.
- when using callgraph (-f) add driver name to callgraph titles.
