Subject: I/O operations priority in RTOS
Date: Sat, 4 Jun 2011 14:03:46 +0200 [thread overview]
Message-ID: <4DEA1F22.6000603@unican.es> (raw)
In-Reply-To: <4DEA1BA9.7020303@unican.es>
Hello,
I'm studying how to develop drivers in a real time OS and how do they
work. I'm using Ubuntu 10.04 with the 2.6.31-11-rt patch installed.
I would like to know the priority when executing open(), read(), write()
and close() operations.
In my example the thread which is using the driver runs with 10 RTPRIO,
but I don't know what happens in kernel context with the priority when
running the I/O operations.
Thank you for your help, I don't know where to learn about this.
Mónica
