1. 解释“failed to allocate default iommu domain of type 4”的含义 "failed to allocate default iommu domain of type 4" 是一个内核错误信息,通常出现在Linux系统的启动或运行期间,特别是在涉及硬件虚拟化(如KVM)或设备隔离(如IOMMU,即输入/输出内存管理单元)时。这个错误表明系统尝试分配一个特定类型(这里...

Keep the types consistent, all the callers of these functions already have obtained a struct arm_smmu_domain, don't needlessly go to/from an iommu_domain through the internal call chains. Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Link: https://lore.kernel.org/r/4-v2-c86cc8c2230...
pci 0000:00:00.0: failed to allocate default IOMMU domain of type 4; falling back to IOMMU_DOMAIN_DMA. These messages are benign. Due to changes in the RHEL8 kernel the default iommu domain type is now IOMMU_DOMAIN_IDENTITY. When the iommu code does domain allocation the call to the int...
