The current\nreclaim algorithm targets pages in LRU order, which is great for fairness at\norder-0 but highly unsuitable if you desire pages at higher orders. To get\npages of higher order we must shoot down a very high proportion of memory;\n\u003e95% in a lot of cases.\n\nThis patch set adds a lumpy reclaim algorithm to the allocator. It targets\ngroups of pages at the specified order anchored at the end of the active and\ninactive lists. This encourages groups of pages at the requested orders to\nmove from active to inactive, and active to free lists. This behaviour is\nonly triggered out of direct reclaim when higher order pages have been\nrequested.\n\nThis patch set is particularly effective when utilised with an\nanti-fragmentation scheme which groups pages of similar reclaimability\ntogether.\n\nThis patch set is based on Peter Zijlstra\u0027s lumpy reclaim V2 patch which forms\nthe foundation. Credit to Mel Gorman for sanitity checking.\n\nMel said:\n\n The patches have an application with hugepage pool resizing.\n\n When lumpy-reclaim is used used with ZONE_MOVABLE, the hugepages pool can\n be resized with greater reliability. Testing on a desktop machine with 2GB\n of RAM showed that growing the hugepage pool with ZONE_MOVABLE on it\u0027s own\n was very slow as the success rate was quite low. Without lumpy-reclaim,\n each attempt to grow the pool by 100 pages would yield 1 or 2 hugepages.\n With lumpy-reclaim, getting 40 to 70 hugepages on each attempt was typical.\n\n[akpm@osdl.org: ia64 pfn_to_nid fixes and loop cleanup]\n[bunk@stusta.de: static declarations for internal functions]\n[a.p.zijlstra@chello.nl: initial lumpy V2 implementation]\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Bob Picco \u003cbob.picco@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ed7ed365172e27b0efe9d43cc962723c7193e34e", "tree": "6c22daf6908f92c64aae2b425e6383fe0ed404ac", "parents": [ "396faf0303d273219db5d7eb4a2879ad977ed185" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Tue Jul 17 04:03:14 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Jul 17 10:22:59 2007 -0700" }, "message": "handle kernelcore\u003d: generic\n\nThis patch adds the kernelcore\u003d parameter for x86.\n\nOnce all patches are applied, a new command-line parameter exist and a new\nsysctl.

This has the effect of keeping all non-movable pages within a\nsingle memory partition while allowing movable allocations to be satisfied\nfrom either partition. The patches may be applied with the list-based\nanti-fragmentation patches that groups pages together based on mobility.\n\nThe size of the zone is determined by a kernelcore\u003d parameter specified at\nboot-time. This specifies how much memory is usable by non-movable\nallocations and the remainder is used for ZONE_MOVABLE. Any range of pages\nwithin ZONE_MOVABLE can be released by migrating the pages or by reclaiming.\n\nWhen selecting a zone to take pages from for ZONE_MOVABLE, there are two\nthings to consider. First, only memory from the highest populated zone is\nused for ZONE_MOVABLE. On the x86, this is probably going to be ZONE_HIGHMEM\nbut it would be ZONE_DMA on ppc64 or possibly ZONE_DMA32 on x86_64. Second,\nthe amount of memory usable by the kernel will be spread evenly throughout\nNUMA nodes where possible. If the nodes are not of equal size, the amount of\nmemory usable by the kernel on some nodes may be greater than others.\n\nBy default, the zone is not as useful for hugetlb allocations because they are\npinned and non-migratable (currently at least). A sysctl is provided that\nallows huge pages to be allocated from that zone. This means that the huge\npage pool can be resized to the size of ZONE_MOVABLE during the lifetime of\nthe system assuming that pages are not mlocked.

These requirements do not make it\nnecessary to audit TTY output as well.\n\nCompared to an user-space keylogger, this approach records TTY input using the\naudit subsystem, correlated with other audit events, and it is completely\ntransparent to the user-space application (e.g. the console ioctls still\nwork).\n\nTTY input auditing works on a higher level than auditing all system calls\nwithin the session, which would produce an overwhelming amount of mostly\nuseless audit events.\n\nAdd an \"audit_tty\" attribute, inherited across fork (). Data read from TTYs\nby process with the attribute is sent to the audit subsystem by the kernel.\nThe audit netlink interface is extended to allow modifying the audit_tty\nattribute, and to allow sending explanatory audit events from user-space (for\nexample, a shell might send an event containing the final command, after the\ninteractive command-line editing and history expansion is performed, which\nmight be difficult to decipher from the TTY input alone).\n\nBecause the \"audit_tty\" attribute is inherited across fork (), it would be set\ne.g. for sshd restarted within an audited session. To prevent this, the\naudit_tty attribute is cleared when a process with no open TTY file\ndescriptors (e.g. after daemon startup) opens a TTY.\n\nSee https://www.redhat.com/archives/linux-audit/2007-June/msg00000.html for a\nmore detailed rationale document for an older version of this patch.\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Miloslav Trmac \u003cmitr@redhat.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nCc: Casey Schaufler \u003ccasey@schaufler-ca.com\u003e\nCc: Steve Grubb \u003csgrubb@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4f27c00bf80f122513d3a5be16ed851573164534", "tree": "2abad49c1e5c93d2d8698c558eb490b99bd35b87", "parents": [ "f3dc8c189a20dc5d115b8f0d07ac620e69eff05c" ], "author": { "name": "Alan Cox", "email": "alan@lxorguk.ukuu.org.uk", "time": "Sun Jul 15 23:40:55 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Jul 16 09:05:46 2007 -0700" }, "message": "Improve behaviour of spurious IRQ detect\n\nCurrently we handle spurious IRQ activity based upon seeing a lot of\ninvalid interrupts, and we clear things back on the base of lots of valid\ninterrupts.\n\nUnfortunately in some cases you get legitimate invalid interrupts caused by\ntiming asynchronicity between the PCI bus and the APIC bus when disabling\ninterrupts and pulling other tricks.

Presently on UP NUMA this has the side-effect of preferring\nnode#0 allocations (since numa_node_id() \u003d\u003d 0, though this could be\nreworked if we could hand off a pfn to determine node placement), so\nsingle-CPU NUMA systems will want to place smaller nodes further out in\nterms of node id. Once a page has been bound to a node (via explicit node\nid typing), we only do block allocations from partial free pages that have\na matching node id in the page flags.\n\nThe current implementation does have some scalability problems, in that all\npartial free pages are tracked in the global freelist (with contention due\nto the single spinlock).

The\nchannel pool is organized as a per-cpu array of channel pointers. The\nasync_tx_rebalance() routine is tasked with managing these arrays. In the\nuniprocessor case async_tx_rebalance() tries to spread responsibility\nevenly over channels of similar capabilities. For example if there are two\ncopy+xor channels, one will handle copy operations and the other will\nhandle xor. In the SMP case async_tx_rebalance() attempts to spread the\noperations evenly over the cpus, e.g. cpu0 gets copy channel0 and xor\nchannel0 while cpu1 gets copy channel 1 and xor channel 1. When a\ndependency is specified async_tx_find_channel defaults to keeping the\noperation on the same channel. A xor-\u003ecopy-\u003exor chain will stay on one\nchannel if it supports both operation types, otherwise the transaction will\ntransition between a copy and a xor resource.\n\nCurrently the raid5 implementation in the MD raid456 driver has been\nconverted to the async_tx api. A driver for the offload engines on the\nIntel Xscale series of I/O processors, iop-adma, is provided in a later\ncommit. With the iop-adma driver and async_tx, raid456 is able to offload\ncopy, xor, and xor-zero-sum operations to hardware engines.\n \nOn iop342 tiobench showed higher throughput for sequential writes (20 - 30%\nimprovement) and sequential reads to a degraded array (40 - 55%\nimprovement). For the other cases performance was roughly equal, +/- a few\npercentage points. On a x86-smp platform the performance of the async_tx\nimplementation (in synchronous mode) was also +/- a few percentage points\nof the original implementation. According to \u0027top\u0027 on iop342 CPU\nutilization drops from ~50% to ~15% during a \u0027resync\u0027 while the speed\naccording to /proc/mdstat doubles from ~25 MB/s to ~50 MB/s.\n \nThe tiobench command line used for testing was: tiobench --size 2048\n--block 4096 --block 131072 --dir /mnt/raid --numruns 5\n* iop342 had 1GB of memory available\n\nDetails:\n* if CONFIG_DMA_ENGINE\u003dn the asynchronous path is compiled away by making\n async_tx_find_channel a static inline routine that always returns NULL\n* when a callback is specified for a given transaction an interrupt will\n fire at operation completion time and the callback will occur in a\n tasklet. if the the channel does not support interrupts then a live\n polling wait will be performed\n* the api is written as a dmaengine client that requests all available\n channels\n* In support of dependencies the api implicitly schedules channel-switch\n interrupts.
