* [PATCH] zoned vm counters: basic ZVC (zoned vm counter) implementationChristoph Lameter2006-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per zone counter infrastructure The counters that we currently have for the VM are split per processor. The processor however has not much to do with the zone these pages belong to. We cannot tell f.e. how many ZONE_DMA pages are dirty. So we are blind to potentially inbalances in the usage of memory in various zones. F.e. in a NUMA system we cannot tell how many pages are dirty on a particular node. If we knew then we could put measures into the VM to balance the use of memory between different zones and different nodes in a NUMA system. For example it would be possible to limit the dirty pages per node so that fast local memory is kept available even if a process is dirtying huge amounts of pages. Another example is zone reclaim. We do not know how many unmapped pages exist per zone. So we just have to try to reclaim. If it is not working then we pause and try again later. It would be better if we knew when it makes sense to reclaim unmapped pages from a zone. This patchset allows the determination of the number of unmapped pages per zone. We can remove the zone reclaim interval with the counters introduced here. Futhermore the ability to have various usage statistics available will allow the development of new NUMA balancing algorithms that may be able to improve the decision making in the scheduler of when to move a process to another node and hopefully will also enable automatic page migration through a user space program that can analyse the memory load distribution and then rebalance memory use in order to increase performance. The counter framework here implements differential counters for each processor in struct zone. The differential counters are consolidated when a threshold is exceeded (like done in the current implementation for nr_pageache), when slab reaping occurs or when a consolidation function is called. Consolidation uses atomic operations and accumulates counters per zone in the zone structure and also globally in the vm_stat array. VM functions can access the counts by simply indexing a global or zone specific array. The arrangement of counters in an array also simplifies processing when output has to be generated for /proc/*. Counters can be updated by calling inc/dec_zone_page_state or _inc/dec_zone_page_state analogous to *_page_state. The second group of functions can be called if it is known that interrupts are disabled. Special optimized increment and decrement functions are provided. These can avoid certain checks and use increment or decrement instructions that an architecture may provide. We also add a new CONFIG_DMA_IS_NORMAL that signifies that an architecture can do DMA to all memory and therefore ZONE_NORMAL will not be populated. This is only currently set for IA64 SGI SN2 and currently only affects node_page_state(). In the best case node_page_state can be reduced to retrieving a single counter for the one zone on the node.

* | [PATCH] Configurable NODES_SHIFTYasunori Goto2006-04-11
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

* [PATCH] ia64: use i386 dmi_scan.cMatt Domsch2006-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | Enable DMI table parsing on ia64. Andi Kleen has a patch in his x86_64 tree which enables the use of i386 dmi_scan.c on x86_64. dmi_scan.c functions are being used by the drivers/char/ipmi/ipmi_si_intf.c driver for autodetecting the ports or memory spaces where the IPMI controllers may be found. This patch adds equivalent changes for ia64 as to what is in the x86_64 tree. In addition, I reworked the DMI detection, such that on EFI-capable systems, it uses the efi.smbios pointer to find the table, rather than brute-force searching from 0xF0000. On non-EFI systems, it continues the brute-force search. My test system, an Intel S870BN4 'Tiger4', aka Dell PowerEdge 7250, with latest BIOS, does not list the IPMI controller in the ACPI namespace, nor does it have an ACPI SPMI table. Also note, currently shipping Dell x8xx EM64T servers don't have these either, so DMI is the only method for obtaining the address of the IPMI controller.

This is not recommended and could potentially cause chipset's to lockup, or cause missing interrupts. CONFIG_IRQ_BALANCE does this correctly, where it re-programs only when the interrupt is pending. The same needs to be done for /proc/irq handling as well. Otherwise user space irq balancers are really not doing the right thing. - Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for lack of a generic name. - added move_irq out of IRQ_BALANCE, and added this same to X86_64 - Added new proc handler for write, so we can do deferred write at irq handling time. - Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead it now shows only active cpu masks, or exactly what was set. - Provided a common move_irq implementation, instead of duplicating when using generic irq framework. Tested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off. Tested UP builds as well.

* | [IA64] remove CONFIG_IA64_SGI_SN_SIMGreg Edwards2005-07-12
|/ | | | | | | | | | This patch removes the CONFIG_IA64_SGI_SN_SIM option entirely, allowing any kernel bootable on sn2 to also be booted in the simulator. Boot tested on Altix and HP rx2600. Signed-off-by: Greg Edwards <edwardsg@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [PATCH] ia64: Selectable Timer Interrupt FrequencyChristoph Lameter2005-06-23
| | | | | | | | | | It allows a selectable timer interrupt frequency of 100, 250 and 1000 HZ. Reducing the timer frequency may have important performance benefits on large systems.

* [PATCH] make each arch use mm/KconfigDave Hansen2005-06-23
| | | | | | | | | | | | | | For all architectures, this just means that you'll see a "Memory Model" choice in your architecture menu. For those that implement DISCONTIGMEM, you may eventually want to make your ARCH_DISCONTIGMEM_ENABLE a "def_bool y" and make your users select DISCONTIGMEM right out of the new choice menu. The only disadvantage might be if you have some specific things that you need in your help option to explain something about DISCONTIGMEM.

| * [IA64] enable SGI simulator for generic kernelsGreg Edwards2005-06-21
| | | | | | | | | | | | | | | | | | | | Allow the SGI simulator (medusa) to work on generic kernels. There is no inherent dependency on an sn2-specific kernel. Boot tested on Altix, medusa and HP rx2600. Signed-off-by: Greg Edwards <edwardsg@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
