Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

Altix: Add initial ACPI IO support First phase in introducing ACPI support to SN. In this phase, when running with an ACPI capable PROM, the DSDT will define the root busses and all SN nodes (SGIHUB, SGITIO). An ACPI bus driver will be registered for the node devices, with the acpi_pci_root_driver being used for the root busses. An ACPI vendor descriptor is now used to pass platform specific information for both nodes and busses, eliminating the need for the current SAL calls. Also, with ACPI support, SN fixup code is no longer needed to initiate the PCI bus scans, as the acpi_pci_root_driver does that. However, to maintain backward compatibility with non-ACPI capable PROMs, none of the current 'fixup' code can been deleted, though much restructuring has been done. For example, the bulk of the code in io_common.c is relocated code that is now common regardless of what PROM is running, while io_acpi_init.c and io_init.c contain routines specific to an ACPI or non ACPI capable PROM respectively. A new pci bus fixup platform vector has been created to provide a hook for invoking platform specific bus fixup from pcibios_fixup_bus(). The size of io_space[] has been increased to support systems with large IO configurations. Signed-off-by: John Keller <jpk@sgi.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
