Subject: [Xenomai-core] FYI: CONFIG_PERF_EVENTS conflicts with Xenomai shadows
Date: Wed, 31 Mar 2010 15:50:37 +0200	[thread overview]
Message-ID: <4BB3532D.2070305@domain.hid> (raw)

Hi,

just ran into an ugly warning of I-pipe as I happened to have
CONFIG_PERF_EVENTS enabled in 2.6.32 kernel. That pulls some plain Linux
spinlock into the finish_task_switch path.

We should either disable this feature at I-pipe level or patch it
properly. Haven't checked yet if the latter is feasible with moderate
effort, though.
