2007-02-03Altix: ACPI SSDT PCI device supportJohn Keller3-5/+10
Add SN platform support for running with an ACPI capable PROM that defines PCI devices in SSDT tables. There is a SSDT table for every occupied slot on a root bus, containing info for every PPB and/or device on the bus. The SSDTs will be dynamically loaded/unloaded at hotplug enable/disable. Platform specific information that is currently passed via a SAL call, will now be passed via the Vendor resource in the ACPI Device object(s) defined in each SSDT.

2006-12-12[IA64] fix possible XPC deadlock when disconnectingDean Nelson1-1/+1
This patch eliminates a potential deadlock that is possible when XPC disconnects a channel to a partition that has gone down. This deadlock will occur if at least one of the kthreads created by XPC for the purpose of making callouts to the channel's registerer is detained in the registerer and will not be returning back to XPC until some registerer request occurs on the now downed partition. The potential for a deadlock is removed by ensuring that there always is a kthread available to make the channel disconnecting callout to the registerer.

2006-12-02Altix: Add initial ACPI IO supportJohn Keller4-13/+32
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>
2006-11-13[PATCH] mspec driver build fixJes Sorensen1-1/+5
Fix MSPEC driver to build for non SN2 enabled configs as the driver should work in cached and uncached modes (no fetchop) on these systems. In addition make MSPEC select IA64_UNCACHED_ALLOCATOR, which is required for it and move it to arch/ia64/Kconfig to avoid warnings on non ia64 architectures running allmodconfig. Once the Kconfig code is fixed, we can move it back.

2006-08-09[IA64-SGI] Silent data corruption caused by XPC V2.Dean Nelson2-5/+21
Jack Steiner identified a problem where XPC can cause a silent data corruption. On module load, the placement may cause the xpc_remote_copy_buffer to span two physical pages. DMA transfers are done to the start virtual address translated to physical. This patch changes the buffer from a statically allocated buffer to a kmalloc'd buffer. Dean Nelson reviewed this before posting. I have tested it in the configuration that was showing the memory corruption and verified it works. I also added a BUG_ON statement to help catch this if a similar situation is encountered.

2006-03-26[PATCH] EFI: keep physical table addresses in efi structureBjorn Helgaas1-1/+1
Almost all users of the table addresses from the EFI system table want physical addresses. So rather than doing the pa->va->pa conversion, just keep physical addresses in struct efi. This fixes a DMI bug: the efi structure contained the physical SMBIOS address on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap() on a virtual address on ia64. This is essentially the same as an earlier patch by Matt Tolentino: http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2 except that this changes all table addresses, not just ACPI addresses. Matt's original patch was backed out because it caused MCAs on HP sx1000 systems. That problem is resolved by the ioremap() attribute checking added for ia64.

2006-02-07[IA64-SGI] - Eliminate SN pio_phys_xxx macros. Move to assemblyJack Steiner1-51/+5
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.

2006-01-14[IA64-SGI] Fix sn_flush_device_kernel & spinlock initializationPrarit Bhargava1-1/+2
This patch separates the sn_flush_device_list struct into kernel and common (both kernel and PROM accessible) structures. As it was, if the size of a spinlock_t changed (due to additional CONFIG options, etc.) the sal call which populated the sn_flush_device_list structs would erroneously write data (and cause memory corruption and/or a panic). This patch does the following: 1. Removes sn_flush_device_list and adds sn_flush_device_common and sn_flush_device_kernel. 2. Adds a new SAL call to populate a sn_flush_device_common struct per device, not per widget as previously done. 3. Correctly initializes each device's sn_flush_device_kernel spinlock_t struct (before it was only doing each widget's first device).
