Yup. > The thing is abbreviated as "SEI" and apparently means "System Error > Interrupt". Nothing else. ARM has 'external abort', which are either synchronous or asynchronous, both are delivered as different types of exception. Asynchronous external abort is treated as a special kind of interrupt, 'SError Interrupt', (where SError stands for System Error, but its rarely written like that). 'SEI' is a relatively new abbreviation for SError interrupt. What should we call this thing? In the ACPI code I'd prefer 'SEI' as that is what the ACPI spec calls it. Here we are talking about an GHES notification. But in the arm64 arch code this should be called SError Interrupt as this is what the ARM-ARM calls it. This code cares about exception routing and interrupt masking. But, I don't really care.
