Hi robin/will/James
In the current kernel, it only handles three kinds of error, which is memory error, PCIE device and ARM process. But now the SMMU already support the RAS, how to handle the SMMU RAS error in the kernel? I check the UEFI_SPEC_2.7, the ACPI's CPER have the IOMMU type, but it seems the IOMMU type only are specific to AMD’s IOMMU specification, not have the ARM’s IOMMU section type, can we reuse this IOMMU section type for the ARM SMMU? N.2.11.3 IOMMU specific DMAr Error Section Type: {0x036F84E1, 0x7F37, 0x428c, {0xA7, 0x9E, 0x57, 0x5F, 0xDF, 0xAA, 0x84, 0xEC}} All fields in this error record are specific to AMD’s IOMMU specification. This error section has a fixed size.
