Subject: [Adeos-main] Unchecked ipipe_test_pipeline_from
Date: Mon, 09 Nov 2009 19:07:27 +0100 [thread overview]
Message-ID: <4AF85A5F.2030203@domain.hid> (raw)
Hi Philippe,
just noticed: The __ipipe_check_percpu_access of __ipipe_get_cpu_var,
added in 2.6.29, makes ipipe_test_pipeline_from unusable for debugging
purposes. It now triggers a false positive warning if the caller did not
disabled interrupts or stalled its pipeline. One such user under Xenomai
is rthal_local_irq_disabled, and that is used to check RTDM driver
handlers /wrt leaking IRQ masks.
Introduce a debug-free ipipe_check_pipeline_from for
rthal_local_irq_disabled?
