Subject: [Xenomai] s3c24xx: Priority rotate enable !?
Date: Wed, 22 Aug 2012 18:04:24 +0200	[thread overview]
Message-ID: <50350308.8010405@openwide.fr> (raw)

Hello,

On s3c24xx processors the interrupt source priority isn't fixed by Adeos 
patch (ARB_SEL bits in PRIORITY register).
Is it intentional ?
It may be possible to give priority to an interrupt simultaneously 
arrived that the interruption IRQ_TIMER4 (before being grabbed by 
Adeos). Therefore, we can have more jitter for real time applications.

Do we need to fix the priority at this level ?

Thanks,
Romain
