- IOAPIC init requires ACPI tables - ACPI subsystem enable requires IOAPIC Hence, we first init ACPI tables, then IOAPIC, then enable ACPI subsystem. Signed-off-by: Sandro Rüegge <[email protected]>
- We need a configure_irq because SCI has special polarity and trigger mode - We need mask_irq to implement ACPICA handler removal Signed-off-by: Sandro Rüegge <[email protected]>
We select an unused interrupt vector. Configure/mask the SCI interrupt in IOAPIC. We send the apic end of interrupt signal. Signed-off-by: Sandro Rüegge <[email protected]>

Fix handling of the system control interrupt in KTF. I am a bit unsure about whether the interrupt routine we have is re-entrant. If not, we might run into issues since we could have a re-entry once we send the acpi_EOI signal?
