Subject: Translation faults with OMAP ISP
Date: Tue, 16 Nov 2010 16:46:27 -0700	[thread overview]
Message-ID: <4CE317D3.2020504@brooks.nu> (raw)

Laurent,

I am getting iommu translation errors when I try to use the CCDC output 
after using the Resizer output.

If I use the CCDC output to stream some video, then close it down, 
switch to the Resizer output and open it up and try to stream, I get the 
following errors spewing out:

omap-iommu omap-iommu.0: omap2_iommu_fault_isr: da:00d0ef00 translation 
fault
omap-iommu omap-iommu.0: iommu_fault_handler: da:00d0ef00 pgd:ce664034 
*pgd:00000000

and the select times out.

 From a fresh boot, I can stream just fine from the Resizer and then 
switch to the CCDC output just fine. It is only when I go from the CCDC 
to the Resizer that I get this problem. Furthermore, when it gets into 
this state, then anything dev node I try to use has the translation 
errors and the only way to recover is to reboot.

Any ideas on the problem?

Thanks,
Lane
