Subject: [Xenomai-core] arm: Unprotected access to irq_desc field?
Date: Thu, 28 Oct 2010 17:38:35 +0200 [thread overview]
Message-ID: <4CC998FB.3070102@domain.hid> (raw)
Gilles,
I happened to come across rthal_mark_irq_disabled/enabled on arm. On
first glance, it looks like these helpers manipulate irq_desc::status
non-atomically, i.e. without holding irq_desc::lock. Isn't this fragile?
