Bug ID: 27877
Summary: Missing -t timing stats support in the bpf backend
Product: systemtap
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: bpf
Assignee: systemtap at sourceware dot org
Reporter: agentzh at gmail dot com
Target Milestone: ---
Currently the bpf backend lacks probe timing stats enabled by the `-t` CLI
option, as evidenced by the following example:
```
$ /opt/stap/bin/stap -t --bpf -e 'probe oneshot { println("Hello world") }'
Hello world
```
For comparison, the default kernel backend runs fine:
```
$ /opt/stap/bin/stap -t -e 'probe oneshot { println("Hello world") }'
Hello world
----- probe hit report:
begin, (<input>:1:7), hits: 1, cycles: 2880min/2880avg/2880max, variance: 0,
from: oneshot from: oneshot, index: 0
----- refresh report:
```
