* [PATCH] NUMA policies in the slab allocator V2Christoph Lameter2006-01-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a regression in 2.6.14 against 2.6.13 that causes an imbalance in memory allocation during bootup. The slab allocator in 2.6.13 is not numa aware and simply calls alloc_pages(). This means that memory policies may control the behavior of alloc_pages(). During bootup the memory policy is set to MPOL_INTERLEAVE resulting in the spreading out of allocations during bootup over all available nodes. The slab allocator in 2.6.13 has only a single list of slab pages. As a result the per cpu slab cache and the spinlock controlled page lists may contain slab entries from off node memory. The slab allocator in 2.6.13 makes no effort to discern the locality of an entry on its lists. The NUMA aware slab allocator in 2.6.14 controls locality of the slab pages explicitly by calling alloc_pages_node(). The NUMA slab allocator manages slab entries by having lists of available slab pages for each node. The per cpu slab cache can only contain slab entries associated with the node local to the processor. This guarantees that the default allocation mode of the slab allocator always assigns local memory if available. Setting MPOL_INTERLEAVE as a default policy during bootup has no effect anymore. In 2.6.14 all node unspecific slab allocations are performed on the boot processor. This means that most of key data structures are allocated on one node. Most processors will have to refer to these structures making the boot node a potential bottleneck. This may reduce performance and cause unnecessary memory pressure on the boot node. This patch implements NUMA policies in the slab layer. There is the need of explicit application of NUMA memory policies by the slab allcator itself since the NUMA slab allocator does no longer let the page_allocator control locality. The check for policies is made directly at the beginning of __cache_alloc using current->mempolicy. The memory policy is already frequently checked by the page allocator (alloc_page_vma() and alloc_page_current()). So it is highly likely that the cacheline is present. For MPOL_INTERLEAVE kmalloc() will spread out each request to one node after another so that an equal distribution of allocations can be obtained during bootup. It is not possible to push the policy check to lower layers of the NUMA slab allocator since the per cpu caches are now only containing slab entries from the current node. If the policy says that the local node is not to be preferred or forbidden then there is no point in checking the slab cache or local list of slab pages. The allocation better be directed immediately to the lists containing slab entries for the allowed set of nodes. This way of applying policy also fixes another strange behavior in 2.6.13. alloc_pages() is controlled by the memory allocation policy of the current process. It could therefore be that one process is running with MPOL_INTERLEAVE and would f.e. obtain a new page following that policy since no slab entries are in the lists anymore. A page can typically be used for multiple slab entries but lets say that the current process is only using one. The other entries are then added to the slab lists. These are now non local entries in the slab lists despite of the possible availability of local pages that would provide faster access and increase the performance of the application. Another process without MPOL_INTERLEAVE may now run and expect a local slab entry from kmalloc(). However, there are still these free slab entries from the off node page obtained from the other process via MPOL_INTERLEAVE in the cache. The process will then get an off node slab entry although other slab entries may be available that are local to that process. This means that the policy if one process may contaminate the locality of the slab caches for other processes. This patch in effect insures that a per process policy is followed for the allocation of slab entries and that there cannot be a memory policy influence from one process to another. A process with default policy will always get a local slab entry if one is available. And the process using memory policies will get its memory arranged as requested. Off-node slab allocation will require the use of spinlocks and will make the use of per cpu caches not possible. A process using memory policies to redirect allocations offnode will have to cope with additional lock overhead in addition to the latency added by the need to access a remote slab entry. Changes V1->V2 - Remove #ifdef CONFIG_NUMA by moving forward declaration into prior #ifdef CONFIG_NUMA section. - Give the function determining the node number to use a saner name.

* [PATCH] Zone reclaim: Reclaim logicChristoph Lameter2006-01-183-5/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some bits for zone reclaim exists in 2.6.15 but they are not usable. This patch fixes them up, removes unused code and makes zone reclaim usable. Zone reclaim allows the reclaiming of pages from a zone if the number of free pages falls below the watermarks even if other zones still have enough pages available. Zone reclaim is of particular importance for NUMA machines. It can be more beneficial to reclaim a page than taking the performance penalties that come with allocating a page on a remote zone. Zone reclaim is enabled if the maximum distance to another node is higher than RECLAIM_DISTANCE, which may be defined by an arch. By default RECLAIM_DISTANCE is 20. 20 is the distance to another node in the same component (enclosure or motherboard) on IA64. The meaning of the NUMA distance information seems to vary by arch. If zone reclaim is not successful then no further reclaim attempts will occur for a certain time period (ZONE_RECLAIM_INTERVAL). This patch was discussed before.

That is needed for some tuners or you can get static as a result. The flag is added for those tuners where I know that the datasheet indicates that this is necessary. - For this new check use the last set div value, not the last frequency as radio frequencies are always much higher due to the 16000 multiplier.

Reusing tuner_range structs, rather than defining new ones for each tuner, will cut down on memory usage, and is preferred when possible. - tunertype struct contains an element, has_tda988x. We must set this for all tunertypes that contain a tda988x chip, and then we can remove this setting from the various card structs. - Improves tuners array memory usage efficiency. - Right now, all tuners are using the first tuner_params[] array element for analog mode. In the future, we will be merging similar tuner definitions together, such that each tuner definition will have a tuner_params struct for each available video standard. At that point, the tuner_params[] array element will be chosen based on the video standard in use.

* | | | [PATCH] x86_64: Flexmap for 32bit and randomized mappings for 64bitAndi Kleen2006-01-162-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Another try at this. For 32bit follow the 32bit implementation from Ingo - mappings are growing down from the end of stack now and vary randomly by 1GB. Randomized mappings for 64bit just vary the normal mmap break by 1TB. I didn't bother implementing full flex mmap for 64bit because it shouldn't be needed there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This builds on some of the clock framework code to support a simple system timer interface.

* | | | [PATCH] sh: Simplistic clock frameworkPaul Mundt2006-01-163-11/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a relatively simplistic clock framework for sh. The initial goal behind this is to clean up the arch/sh/kernel/time.c mess and to get the CPU subtype-specific frequency setting and calculation code moved somewhere more sensible. This only deals with the core clocks at the moment, though it's trivial for other drivers to define their own clocks as desired.
