Roger Pau Monné 44e06d158a msi: add Xen MSI implementation ... This patch adds support for MSI interrupts when running on Xen. Apart from adding the Xen related code needed in order to register MSI interrupts this patch also makes the msi_init function a hook in init_ops, so different MSI implementations can have different initialization functions. Sponsored by: Citrix Systems R&D xen/interface/physdev.h: - Add the MAP_PIRQ_TYPE_MULTI_MSI to map multi-vector MSI to the Xen public interface. x86/include/init.h: - Add a hook for setting custom msi_init methods. amd64/amd64/machdep.c: i386/i386/machdep.c: - Set the default msi_init hook to point to the native MSI initialization method. x86/xen/pv.c: - Set the Xen MSI init hook when running as a Xen guest. x86/x86/local_apic.c: - Call the msi_init hook instead of directly calling msi_init. xen/xen_intr.h: x86/xen/xen_intr.c: - Introduce support for registering/releasing MSI interrupts with Xen. - The MSI interrupts will use the same PIC as the IO APIC interrupts. xen/xen_msi.h: x86/xen/xen_msi.c: - Introduce a Xen MSI implementation. x86/xen/xen_nexus.c: - Overwrite the default MSI hooks in the Xen Nexus to use the Xen MSI implementation. x86/xen/xen_pci.c: - Introduce a Xen specific PCI bus that inherits from the ACPI PCI bus and overwrites the native MSI methods. - This is needed because when running under Xen the MSI messages used to configure MSI interrupts on PCI devices are written by Xen itself. dev/acpica/acpi_pci.c: - Lower the quality of the ACPI PCI bus so the newly introduced Xen PCI bus can take over when needed. conf/files.i386: conf/files.amd64: - Add the newly created files to the build process.		2014-09-30 16:46:45 +00:00
