[Bug 2076190] Re: perf build disables tracepoint support

This bug is awaiting verification that the linux-xilinx/6.8.0-1009.10
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-noble-linux-xilinx' to 'verification-done-
noble-linux-xilinx'. If the problem still exists, change the tag
'verification-needed-noble-linux-xilinx' to 'verification-failed-noble-
linux-xilinx'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
perf build disables tracepoint support

Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Noble:
Fix Committed
Status in linux source package in Oracular:
Fix Released

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
