From b1bb248a5d2230a3d8ef42199c742194a8580b15 Mon Sep 17 00:00:00 2001 From: Kenji Kaneshige Date: Thu, 28 Apr 2005 00:25:58 -0700 Subject: [PATCH] ACPI based I/O APIC hot-plug: add interfaces This patch adds the following new interfaces for I/O xAPIC hotplug. The implementation of these interfaces depends on each architecture. o int acpi_register_ioapic(acpi_handle handle, u64 phys_addr, u32 gsi_base); This new interface is to add a new I/O xAPIC specified by phys_addr and gsi_base pair. phys_addr is the physical address to which the I/O xAPIC is mapped and gsi_base is global system interrupt base of the I/O xAPIC. acpi_register_ioapic returns 0 on success, or negative value on error. o int acpi_unregister_ioapic(acpi_handle handle, u32 gsi_base); This new interface is to remove a I/O xAPIC specified by gsi_base. acpi_unregister_ioapic returns 0 on success, or negative value on error.
