Currently, those patches can not work at my eCarrizo board.
When I merged your patches, boot failed, and no any info print to me.
I set iommu=pt, it also does not work; set iommu=soft, boot ok.
When I removed those patches, kernel boot ok.
This eCarrizo board uart doesnot work, so I can not get useful
information from kernel by uart console, I also set 'text' in boot
option, but still cannot print any log.
Thanks for your testing. The issue turned out to be an older bug, which
just got uncovered by these patches. I updated the branch at
git://git.kernel.org/pub/scm/linux/kernel/git/joro/linux.git amd-iommu-iova
This branch boots now on my Kaveri and Carrizo system. Can you please
give it a test too?
Thanks,
Joerg
