APEI is currently implemented so that it depends on x86 hardware.
The primary dependency is that GHES uses the x86 NMI for hardware
error notification. These patches remove that dependency.
Other APEI features such as error reporting via external IRQ, error
serialization, or error injection, do not require changes to use them
on non-x86 architectures.
The following patch set eliminates the APEI Kconfig x86 dependency
by making these changes:
- replace arch specific calls with more generic one
- treat NMI notification as GHES feature - CONFIG_ACPI_APEI_NMI
- isolate NMI related code
- reorganize function logic
NMI code is kept in ghes.c file since NMI and IRQ context are tightly coupled.
Note, these patches introduce no functional changes for x86. The NMI notification
feature is selected for x86 by default. Architectures that want to use this
feature should also provide NMI code infrastructure.
Tomasz Nowicki (7):
apei, mce: Call MCE-specific code only for X86 architecture.
acpi, apei, ghes: Introduce more generic mechanism to init/deinit
GHES error notifications.
ACPI, APEI, GHES: Introduce ACPI_NMI to make NMI error notification a
GHES feature.
acpi, apei, ghes: Factor out NMI error notification context.
acpi, apei, ghes: Attach NMI init/deinit functions while
CONFIG_ACPI_NMI is enabled.
acpi, apei, ghes: Make unmapping functionality independent from
architecture.
acpi, apei, ghes: Factor out ioremap virtual memory for IRQ and NMI
context.
