* [IA64-SGI] One new use of "UNCACHED" needed fixing for sn2 region cleanupTony Luck2005-08-291-1/+1
| | | | | | | | Some shub2 changes were not in the tree when Greg cleaned up the sn2 region definitions in 1b66776da71e33dff5edcc0b096ec3b7c40c75ad, so this one didn't get fixed. Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | Clean up of SGI SN partitioning related code. The SN_SAL_GET_SN_INFO SAL call returns the partition ID, making the SN_SAL_SYSCTL_PARTITION_GET SAL call redundant. Remove sn_partid and use sn_partition_id.

* | [IA64-SGI] - New SN hardware support - ptc_fixesJack Steiner2005-08-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | Shub2 provides a much improved mechanism for issuing internode TLB purges. Add code to support the newer mechanism. There is also some debug code (disabled) that is useful for testing. Collect statistics on the number, type & duration of TLB purges. This data will be useful for making future improvements in the algorithms. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | Update the SN address macros so that they work on both shub1 and shub2. Most of the code to support shub2 was added last year but this patch fixes a few bugs and adds macros to help generate both processor-specific physical addresses & numalink physical addresses. More cleanup & optimization will be done later. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

* [IA64] Altix pcibus_to_node implementationChristoph Lameter2005-07-122-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Altix subarch does not provide node information via ACPI. Instead hooks are used to fixup pci structures. This patch determines the nodes for Altix PCI busses. Remote Bridges: --------------- Altix supports remote I/O nodes without memory or processors but with bridges. The TIOCA type of bridge is an AGP bridge and the PROM provides information about the closest node. That information will be returned by pcibus_to_node. The TIOCP remote bridge type is a PCI bridge but the PROM does not provide a closest node id. pcibus_to_node will return -1 for devices on those bridges meaning that device control structures may be allocated on any node. Safeguard: ---------- Should the fixups result in invalid node information for a pci controller then a warning will be printed and pcibus_to_node will return -1. This patch also fixes the "FIXME" in sn_dma_alloc_coherent. This means that dma_alloc_coherent will now use alloc_pages_node to allocate memory local to the node that the PCI device is connected to.

* [IA64] fix generic/up buildsTony Luck2005-07-062-5/+1
| | | | | | | | | | | | | | Jesse Barnes provided the original version of this patch months ago, but other changes kept conflicting with it, so it got deferred. Greg Edwards dug it out of obscurity just over a week ago, and almost immediately another conflicting patch appeared (Bob Picco's memory-less nodes). I've resolved the conflicts and got it running again. CONFIG_SGI_TIOCX is set to "y" in defconfig, which causes a Tiger to not boot (oops in tiocx_init). But that can be resolved later ... get this in now before it gets stale again. Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64] hotplug/ia64: SN Hotplug Driver - PREEMPT/pcibus_info fixPrarit Bhargava2005-07-061-1/+2
| | | | | | | | | This patch fixes an issue with the PROM and a kernel running with CONFIG_PREEMPT enabled.

| | | | | | | | | | | | | | | This patch is a sparse compile cleanup of shub_mmr.h using both the defconfig and the sn2_defconfig config files. The issue with this file was the missing usage of __IA64_UL_CONST wrapper. This wrapper is defined in include/asm-ia64/types.h and wraps a long constant definition with UL or with nothing depending on its usage in the kernel. The missing wrapper caused many sparse compile errors like warning: constant 0x0x0000000010000380 so big it is long Signed-off-by: Prarit Bhargava <prarit@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
