Subject: Why is the DENABLE_LTTNG compiler option in rdma-core disabled by default?
Date: Thu, 14 Nov 2024 14:57:21 +0800	[thread overview]
Message-ID: <8fe49262-98cf-6b43-4f55-b09a8ae449ca@hisilicon.com> (raw)

Hi all!

We've been working on LTTng tracing for hns userspace provider
recently, and we wonder why the DENABLE_LTTNG compiler option
in rdma-core is disabled by default.

If it's due to the concern about performance degradation, we have
tested it on hns and found no significant performance difference
when the tracepoints are disabled.

Or is it because it introduces additional compilation dependency
on LTTng library?

Thanks,
Junxian
