* [IA64] - Make pfn_valid more precise for SGI Altix systemsDean Roe2005-11-291-1/+2
| | | | | | | | | | | A single SGI Altix system can be divided into multiple partitions, each running their own instance of the Linux kernel. pfn_valid() is currently not optimal for any but the first partition, since it does not compare the pfn with min_low_pfn before calling the more costly ia64_pfn_valid().

* [IA64] 4-level page tablesRobin Holt2005-11-113-18/+85
| | | | | | | | | | | | | This patch introduces 4-level page tables to ia64. I have run some benchmarks and found nothing interesting. Performance has consistently fallen within the noise range. It also introduces a config option (setting the default to 3 levels). The config option prevents having 4 level page tables with 64k base page size.

* [PATCH] PCI: Change MSI to use physical delivery mode alwaysAshok Raj2005-11-101-3/+0
| | | | | | | | | | | | | | | | | MSI hardcoded delivery mode to use logical delivery mode. Recently x86_64 moved to use physical mode addressing to support physflat mode. With this mode enabled noticed that my eth with MSI werent working. msi_address_init() was hardcoded to use logical mode for i386 and x86_64. So when we switch to use physical mode, things stopped working. Since anyway we dont use lowest priority delivery with MSI, its always directed to just a single CPU. Its safe and simpler to use physical mode always, even when we use logical delivery mode for IPI's or other ioapic RTE's.

We need multiple notification points for these events because they can take many seconds to run which has nasty effects on the behaviour of the rest of the system. DIE_SS replaced by a generic DIE_FAULT which checks the vector number, to allow interception of faults other than SS. DIE_MACHINE_{HALT,RESTART} added to allow last minute close down processing, especially when the halt/restart routines are called from error handlers. DIE_OOPS added. The check for kprobe's break numbers has been moved from traps.c to kprobes.c, allowing DIE_BREAK to be used for any additional break numbers, i.e. it is no longer kprobes specific. Hooks for kernel debuggers and kernel dumpers added, ENTER and LEAVE. Both of these disable the system for long periods which impact on watchdogs and heartbeat systems in general. More patches to come that use these events to reset watchdogs and heartbeats. unregister_die_notifier() added and both routines exported. Requested by Dean Nelson. Lock removed from {un,}register_die_notifier. notifier_chain_register() already takes a lock. Also the generic notifier chain locking is being reworked to distinguish between callbacks that can block and those that cannot, the lock in {un,}register_die_notifier would interfere with that change. http://marc.theaimsgroup.com/?l=linux-kernel&m=113018709002036&w=2 Leading white space removed from arch/ia64/kernel/kprobes.c.

They continue to keep their implementations. For sh64 I had to add a sh64_ptrace wrapper because it does some initialization on the first call.

* [PATCH] mm: tlb_finish_mmu forget rssHugh Dickins2005-10-291-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | zap_pte_range has been counting the pages it frees in tlb->freed, then tlb_finish_mmu has used that to update the mm's rss. That got stranger when I added anon_rss, yet updated it by a different route; and stranger when rss and anon_rss became mm_counters with special access macros. And it would no longer be viable if we're relying on page_table_lock to stabilize the mm_counter, but calling tlb_finish_mmu outside that lock. Remove the mmu_gather's freed field, let tlb_finish_mmu stick to its own business, just decrement the rss mm_counter in zap_pte_range (yes, there was some point to batching the update, and a subsequent patch restores that). And forget the anal paranoia of first reading the counter to avoid going negative - if rss does go negative, just fix that bug. Remove the mmu_gather's flushes and avoided_flushes from arm and arm26: no use was being made of them. But arm26 alone was actually using the freed, in the way some others use need_flush: give it a need_flush. arm26 seems to prefer spaces to tabs here: respect that.

* [PATCH] mm: tlb_is_full_mm was obscureHugh Dickins2005-10-291-6/+0
| | | | | | | | | | | | | | | | tlb_is_full_mm? What does that mean? The TLB is full? No, it means that the mm's last user has gone and the whole mm is being torn down. And it's an inline function because sparc64 uses a different (slightly better) "tlb_frozen" name for the flag others call "fullmm". And now the ptep_get_and_clear_full macro used in zap_pte_range refers directly to tlb->fullmm, which would be wrong for sparc64. Rather than correct that, I'd prefer to scrap tlb_is_full_mm altogether, and change sparc64 to just use the same poor name as everyone else - is that okay?

| | | | | | | | | | | | | tlb_gather_mmu dates from before kernel preemption was allowed, and uses smp_processor_id or __get_cpu_var to find its per-cpu mmu_gather. That works because it's currently only called after getting page_table_lock, which is not dropped until after the matching tlb_finish_mmu. But don't rely on that, it will soon change: now disable preemption internally by proper get_cpu_var in tlb_gather_mmu, put_cpu_var in tlb_finish_mmu.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flush_tlb_all() can be a scaling issue on large SGI Altix systems since it uses the global call_lock and always executes on all cpus. When a process enters flush_tlb_range() to purge TLBs for another process, it is possible to avoid flush_tlb_all() and instead allow sn2_global_tlb_purge() to purge TLBs only where necessary. This patch modifies flush_tlb_range() so that this case can be handled by platform TLB purge functions and updates ia64_global_tlb_purge() accordingly. sn2_global_tlb_purge() now calculates the region register value from the mm argument introduced with this patch.

This patch attempts to clean them up. Some of the various SN MAX_xxx #defines were also unclear & misused. The primary changes are: - use MAX_NUMNODES. This is the generic linux #define for the number of nodes that are known to the generic kernel. Arrays & loops for constructs that are 1:1 with linux-defined nodes should use the linux #define - not an SN equivalent. - use MAX_COMPACT_NODES for MAX_NUMNODES + NUM_TIOS. This is the number of nodes in the SSI system. Compact nodes are a hack to get around the IA64 architectural limit of 256 nodes. Large SGI systems have more than 256 nodes. When we upgrade to ACPI3.0, I _hope_ that all nodes will be real nodes that are known to the generic kernel. That will allow us to delete the notion of "compact nodes". - add MAX_NUMALINK_NODES for the total number of nodes that are in the numalink domain - all partitions. - simplified (understandable) scan_for_ionodes() - small amount of cleanup related to cnodes Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

Services like ACPI namespace are not available and there are non-trivial problems to moving them to early boot. However, there's no reason we can't change to a different machvec later in boot when the services we need are available. By adding a entry point for later initialization of the swiotlb, we can add an error path for the hpzx1 machevec initialization and fall back to the DIG machine vector if IOMMU hardware isn't found in the system. Since ia64 uses 4GB for zone DMA (no ISA support), it's trivial to allocate a contiguous range from the slab for bounce buffer usage.
