Subject: [Bug bpf/24543] New: stapbpf breaks when cpu0 is disabled
Date: Thu, 09 May 2019 18:52:00 -0000 [thread overview]
Message-ID: <bug-24543-6586@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=24543
Bug ID: 24543
Summary: stapbpf breaks when cpu0 is disabled
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: bpf
Assignee: systemtap at sourceware dot org
Reporter: me at serhei dot io
Target Milestone: ---
There is code in stapbpf to handle the case when some cpu cores are disabled.
However, certain things in stapbpf.cxx are still hardcoded to cpu0 (e.g. perf
group fd). If cpu0 is disabled, stapbpf doesn't work.
