Subject: [ECOS] cyg_scheduler_lock and DSR's
Date: Mon, 07 Sep 2009 16:10:00 -0000 [thread overview]
Message-ID: <110701.39566.qm@web87005.mail.ird.yahoo.com> (raw)
In-Reply-To: <4AA4EE58.2050100@dallaway.org.uk>
Hi,
Is the cyg_scheduler_lock() call not supposed to prevent DSR's from running?
I have a alarm, attached to the realtime clock which when activated posts a message to a custom queue system. This queue is also posted to by user land code..
Pushes to the queue are protected by a mutex. Additionally around the mutex I have the cyg_scheduler_lock() and cyg_scheduler_unlock() to prevent the DSR posting a message whilst inside the mutex operation.
However I`m seeing asserts stating the mutex is already locked. A quick breakpoint and I can see that the DSR is still being called even after the lock() function..
Any thoughts?
James
