Hi,

 

I am currently running Xen with SMMU enabled on an ARM64 platform with 4 Cortex-A72 cores, GICv2 and SMMUv2. There are SMMU faults when booting Dom0, such as:

 

                [    3.972767] mmc0: sdhci: Resp(XEN) smmu: /soc/iommu@9000000: Unhandled context fault: fsr=0x402, iova=0xea060200, fsynr=0x180000, cb=0  

 

Has someone encountered such problems and can provide some guidelines for SMMU support on Dom0?

 

Regards,

Anda
