Title:
perf build disables tracepoint support
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Noble:
Confirmed
Status in linux source package in Oracular:
Confirmed
Bug description:
Since commit 92550b568d, the perf build for Ubuntu kernels does not
link to libtraceevent, and thus cannot perform any operations on
tracepoints, including processing perf.data files that contain
tracepoint events. This is a significant loss of functionality.
Attempts to utilize tracepoints fail with the following:
perf record -e skb:kfree_skb
event syntax error: 'skb:kfree_skb'
\___ unsupported tracepoint
libtraceevent is necessary for tracepoint support
