ia64: remove support for the SGI SN2 platform

2019-08-16T18:33:57Z

The SGI SN2 (early Altix) is a very non-standard IA64 platform that was at the very high end of even IA64 hardware, and has been discontinued a long time ago. Remove it because there no upstream users left, and it has magic hooks all over the kernel.

ia64: prefix header search path with $(srctree)/

2019-03-13T17:39:09Z

Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter"). I removed some header search paths because I was able to build ia64 without them.

ia64: fix sn to add include files using EXTRA_CFLAGS

2007-10-12T19:15:31Z

Changing the global CPPFLAGS is not the recommended way to add additional include dirs. Changed to use EXTRA_CFLAGS. Signed-off-by: Sam Ravnborg Acked-by: Jes Sorensen

Altix: Add initial ACPI IO support

2006-12-01T22:36:57Z

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 Signed-off-by: Greg Kroah-Hartman

[IA64-SGI] - Eliminate SN pio_phys_xxx macros. Move to assembly

2006-02-07T17:24:14Z

Rewrite the SN pio_phys_xxx macros in assembly language. This avoids issues with the Intel icc compiler. Function call overhead is not an issue - the functions reference PIOs and take 100's nsec to complete. In addition, the functions should likely be in assembly language anyway - they reference memory using physical addressing mode. One function executes with psr.ic disabled.

[IA64-SGI] Recursive flags do not work for selective builds

2006-01-26T21:17:34Z

arch/ia64/sn/Makefile sets CPPFLAGS, expecting that setting to propogate to all the subdirectories. For a normal build with its recursive descent it does work, but doing a selective build like 'make arch/ia64/sn/kernel/io_init.i' does not do a recursive descent, it goes directly to arch/ia64/sn/kernel/Makefile so the flags do not get set. To support selective builds, set the flags in all the subordinate Makefiles. Signed-off-by: Keith Owens Signed-off-by: Tony Luck
