Maybe an ECR for the ACPI spec? acpi_bus_init_irq() is going to pass ACPI_IRQ_MODEL_RINTC to _PIC, and ACPI r6.5, sec 5.8.1 only mentions the ACPI_IRQ_MODEL_PIC, ACPI_IRQ_MODEL_IOAPIC, and ACPI_IRQ_MODEL_IOSAPIC values. Even the existing ACPI_IRQ_MODEL_PLATFORM, ACPI_IRQ_MODEL_GIC, and ACPI_IRQ_MODEL_LPIC values aren't mentioned in ACPI r6.5. > ACPI_IRQ_MODEL_COUNT > }; > > -- > 2.40.1 >

Add the IRQ model for RISC-V INTC so that acpi_set_irq_model can use this for RISC-V. Signed-off-by: Sunil V L <sunilvl@ventanamicro.com> --- drivers/acpi/bus.c | 3 +++ include/linux/acpi.h | 1 + 2 files changed, 4 insertions(+)
