Similar to commit 111d0bda8eeb ("tools/kvm_stat: Exempt time-based
counters"), we should not show timer values in kvm_stat. Remove the new
halt_wait_ns.

If this service is enabled and the system rebooted, Systemd's initial
attempt to start this unit file may fail in case the kvm module is not
loaded. Since we did not specify a delay for the retries, Systemd
restarts with a minimum delay a number of times before giving up and
disabling the service. Which means a subsequent kvm module load will
have kvm running without monitoring.
Adding a delay to fix this.

The new counters halt_poll_success_ns and halt_poll_fail_ns do not count
events. Instead they provide a time, and mess up our statistics. Therefore,
we should exclude them.
Removal is currently implemented with an exempt list. If more counters like
these appear, we can think about a more general rule like excluding all
fields name "*_ns", in case that's a standing convention.

To integrate with logrotate, we have a signal handler that will re-open
the logfile.
Assuming we have a systemd unit file with
ExecStart=kvm_stat -dtc -s 10 -L /var/log/kvm_stat.csv
ExecReload=/bin/kill -HUP $MAINPID
and a logrotate config featuring
postrotate
/bin/systemctl reload kvm_stat.service
endscript
Then the overall flow will look like this:
(1) systemd starts kvm_stat, logging to A.
(2) At some point, logrotate runs, moving A to B.
kvm_stat continues to write to B at this point.
(3) After rotating, logrotate restarts the kvm_stat unit via systemctl.
(4) The kvm_stat unit sends a SIGHUP to kvm_stat, finally making it
switch over to writing to A again.
Note that in order to keep the structure of the cvs output in tact, we
make sure to, in contrast to the standard log format, only write the
header once at the beginning of a file. This implies that the header is
suppressed when appending to an existing file. Unlike with the standard
format, where we append to an existing file by starting out with a
header.

optparse is deprecated for a while, hence switching over to argparse
(which also works with python2).
As a consequence, help output has some subtle changes, the most

instead of a universal '[options]' indicator. Also, some of the error

The filter name is fixed to "exit_reason" for some kvm_exit events, no
matter what architect we have. Actually, the filter name ("exit_reason")
is only applicable to x86, meaning it's broken on other architects
including aarch64.
This fixes the issue by providing various kvm_exit filter names, depending
on architect we're on. Afterwards, the variable filter name is picked and
applied through ioctl(fd, SET_FILTER).

The fields filter would not work with child fields, as the respective
parents would not be included. No parents displayed == no childs displayed.
To reproduce, run on s390 (would work on other platforms, too, but would
require a different filter name):
- Run 'kvm_stat -d'
- Press 'f'
- Enter 'instruct'
Notice that events like instruction_diag_44 or instruction_diag_500 are not
displayed - the output remains empty.
With this patch, we will filter by matching events and their parents.
However, consider the following example where we filter by
instruction_diag_44:
kvm statistics - summary
regex filter: instruction_diag_44
Event Total %Total CurAvg/s
exit_instruction 276 100.0 12
instruction_diag_44 256 92.8 11
Total 276 12
Note that the parent ('exit_instruction') displays the total events, but
the childs listed do not match its total (256 instead of 276). This is
intended (since we're filtering all but one child), but might be confusing
on first sight.

Note that the code is still python2 compliant, so folks in bad use can

negative CurAvg/s, which looks rather confusing.
If so, suppress the body refresh and print a message instead.
To reproduce, have at least one guest A completely booted. Then start
another guest B (which generates a huge amount of events), then destroy B.

When setting a PID filter in debugfs, we unnecessarily reset the
statistics, although there is no reason to do so. This behavior was
merely introduced with commit 9f114a03c6854f "tools/kvm_stat: add
interactive command 'r'", most likely to mimic the behavior of
the tracepoints provider in this respect. However, there are plenty
of differences between the two providers, so there is no reason not
to take advantage of the possibility to filter by PID without
resetting the statistics.

We keep the current logic that sorts all events (parent and child), but
re-shuffle the events afterwards, grouping the children after the
respective parent. Note that the percentage column for child events
gives the percentage of the parent's total.
Since we rework the logic anyway, we modify the total average
calculation to use the raw numbers instead of the (rounded) averages.
Note that this can result in differing numbers (between total average
and the sum of the individual averages) due to rounding errors.

Drilldown (i.e. toggle display of child trace events) was implemented by
overriding the fields filter. This resulted in inconsistencies: E.g. when
drilldown was not active, adding a filter that also matches child trace
events would not only filter fields according to the filter, but also add
in the child trace events matching the filter. E.g. on x86, setting
'kvm_userspace_exit' as the fields filter after startup would result in
display of kvm_userspace_exit(DCR), although that wasn't previously
present - not exactly what one would expect from a filter.
This patch addresses the issue by keeping drilldown and fields filter
separate. While at it, we also fix a PEP8 issue by adding a blank line
at one place (since we're in the area...).
We implement this by adding a framework that also allows to define a
taxonomy among the debugfs events to identify child trace events. I.e.
drilldown using 'x' can now also work with debugfs. A respective parent-
child relationship is only known for S390 at the moment, but could be
added adjusting other platforms' ARCH.dbg_is_child() methods
accordingly.

Child trace events were included in calculation of the overall total,
which is used for calculation of the percentages of the '%Total' column.
However, the parent trace envents' stats summarize the child trace
events, hence we'd incorrectly account for them twice, leading to
slightly wrong stats.
With this fix, we use the correct total. Consequently, the sum of the
child trace events' '%Total' column values is identical to the
respective value of the respective parent event. However, this also
means that the sum of the '%Total' column values will aggregate to more
than 100 percent.
