It also adds synthetic tests to compare the performance of\ninterval trees vs prio trees. Short answers is that interval trees are\nslightly faster (~25%) on insert/erase, and much faster (~2.4 - 3x)\non search. It is debatable how realistic the synthetic test is, and I have\nnot made such measurements yet, but my impression is that interval trees\nwould still come out faster.\n\nPatch 2 uses a preprocessor template to make the interval tree generic,\nand uses it as a replacement for the vma prio_tree.\n\nPatch 3 takes the other prio_tree user, kmemleak, and converts it to use\na basic rbtree. We don\u0027t actually need the augmented rbtree support here\nbecause the intervals are always non-overlapping.\n\nPatch 4 removes the now-unused prio tree library.\n\nPatch 5 proposes an additional optimization to rb_erase_augmented, now\nproviding it as an inline function so that the augmented callbacks can be\ninlined in. This provides an additional 5-10% performance improvement\nfor the interval tree insert/erase benchmark. There is a maintainance cost\nas it exposes augmented rbtree users to some of the rbtree library internals;\nhowever I think this cost shouldn\u0027t be too high as I expect the augmented\nrbtree will always have much less users than the base rbtree.\n\nI should probably add a quick summary of why I think it makes sense to\nreplace prio trees with augmented rbtree based interval trees now. One of\nthe drivers is that we need augmented rbtrees for Rik\u0027s vma gap finding\ncode, and once you have them, it just makes sense to use them for interval\ntrees as well, as this is the simpler and more well known algorithm. prio\ntrees, in comparison, seem *too* clever: they impose an additional \u0027heap\u0027\nconstraint on the tree, which they use to guarantee a faster worst-case\ncomplexity of O(k+log N) for stabbing queries in a well-balanced prio\ntree, vs O(k*log N) for interval trees (where k\u003dnumber of matches,\nN\u003dnumber of intervals). Now this sounds great, but in practice prio trees\ndon\u0027t realize this theorical benefit. First, the additional constraint\nmakes them harder to update, so that the kernel implementation has to\nsimplify things by balancing them like a radix tree, which is not always\nideal. Second, the fact that there are both index and heap properties\nmakes both tree manipulation and search more complex, which results in a\nhigher multiplicative time constant. As it turns out, the simple interval\ntree algorithm ends up running faster than the more clever prio tree.\n\nThis patch:\n\nAdd two test modules:\n\n- prio_tree_test measures the performance of lib/prio_tree.c, both for\n insertion/removal and for stabbing searches\n\n- interval_tree_test measures the performance of a library of equivalent\n functionality, built using the augmented rbtree support.\n\nIn order to support the second test module, lib/interval_tree.c is\nintroduced. It is kept separate from the interval_tree_test main file\nfor two reasons: first we don\u0027t want to provide an unfair advantage\nover prio_tree_test by having everything in a single compilation unit,\nand second there is the possibility that the interval tree functionality\ncould get some non-test users in kernel over time.\n\nSigned-off-by: Michel Lespinasse \u003cwalken@google.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Hillf Danton \u003cdhillf@gmail.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Catalin Marinas \u003ccatalin.marinas@arm.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: David Woodhouse \u003cdwmw2@infradead.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "910a742d4ba863848c7283d69c21bfa779d3b9a8", "tree": "324d473754194d806fdd254f5a4e58dfc8b4a221", "parents": [ "bf7ad8eeab995710c766df49c9c69a8592ca0216" ], "author": { "name": "Michel Lespinasse", "email": "walken@google.com", "time": "Mon Oct 08 16:30:39 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Oct 09 16:22:33 2012 +0900" }, "message": "rbtree: performance and correctness test\n\nThis small module helps measure the performance of rbtree insert and\nerase.\n\nAdditionally, we run a few correctness tests to check that the rbtrees\nhave all desired properties:\n\n- contains the right number of nodes in the order desired,\n- never two consecutive red nodes on any path,\n- all paths to leaf nodes have the same number of black nodes,\n- root node is black\n\n[akpm@linux-foundation.org: fix printk warning: sparc64 cycles_t is unsigned long]\nSigned-off-by: Michel Lespinasse \u003cwalken@google.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nAcked-by: David Woodhouse \u003cDavid.Woodhouse@intel.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Daniel Santos \u003cdaniel.santos@pobox.com\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: \"Eric W.

(modern x86 Intel CPUs\n with the \u0027LBR\u0027 hardware feature currently.)\n\n This new feature is basically a sophisticated \u0027magnifying glass\u0027 for\n branch execution - something that is pretty difficult to extract from\n regular, function histogram centric profiles.\n\n The simplest mode is activated via \u0027perf record -b\u0027, and the result\n looks like this in perf report:\n\n\t$ perf record -b any_call,u -e cycles:u branchy\n\n\t$ perf report -b --sort\u003dsymbol\n\t 52.34% [.] main [.] f1\n\t 24.04% [.] f1 [.] f3\n\t 23.60% [.] f1 [.] f2\n\t 0.01% [k] _IO_new_file_xsputn [k] _IO_file_overflow\n\t 0.01% [k] _IO_vfprintf_internal [k] _IO_new_file_xsputn\n\t 0.01% [k] _IO_vfprintf_internal [k] strchrnul\n\t 0.01% [k] __printf [k] _IO_vfprintf_internal\n\t 0.01% [k] main [k] __printf\n\n This output shows from/to branch columns and shows the highest\n percentage (from,to) jump combinations - i.e. the most likely taken\n branches in the system. \"branches\" can also include function calls\n and any other synchronous and asynchronous transitions of the\n instruction pointer that are not \u0027next instruction\u0027 - such as system\n calls, traps, interrupts, etc.\n\n This feature comes with (hopefully intuitive) flat ascii and TUI\n support in perf report.\n\n - Various \u0027perf annotate\u0027 visual improvements for us assembly junkies.\n It will now recognize function calls in the TUI and by hitting enter\n you can follow the call (recursively) and back, amongst other\n improvements.\n\n - Multiple threads/processes recording support in perf record, perf\n stat, perf top - which is activated via a comma-list of PIDs:\n\n\tperf top -p 21483,21485\n\tperf stat -p 21483,21485 -ddd\n\tperf record -p 21483,21485\n\n - Support for per UID views, via the --uid paramter to perf top, perf\n report, etc. For example \u0027perf top --uid mingo\u0027 will only show the\n tasks that I am running, excluding other users, root, etc.\n\n - Jump label restructurings and improvements - this includes the\n factoring out of the (hopefully much clearer) include/linux/static_key.h\n generic facility:\n\n\tstruct static_key key \u003d STATIC_KEY_INIT_FALSE;\n\n\t...\n\n\tif (static_key_false(\u0026key))\n\t do unlikely code\n\telse\n\t do likely code\n\n\t...\n\tstatic_key_slow_inc();\n\t...\n\tstatic_key_slow_inc();\n\t...\n\n The static_key_false() branch will be generated into the code with as\n little impact to the likely code path as possible. the\n static_key_slow_*() APIs flip the branch via live kernel code patching.\n\n This facility can now be used more widely within the kernel to\n micro-optimize hot branches whose likelihood matches the static-key\n usage and fast/slow cost patterns.\n\n - SW function tracer improvements: perf support and filtering support.\n\n - Various hardenings of the perf.data ABI, to make older perf.data\u0027s\n smoother on newer tool versions, to make new features integrate more\n smoothly, to support cross-endian recording/analyzing workflows\n better, etc.\n\n - Restructuring of the kprobes code, the splitting out of \u0027optprobes\u0027,\n and a corner case bugfix.\n\n - Allow the tracing of kernel console output (printk).\n\n - Improvements/fixes to user-space RDPMC support, allowing user-space\n self-profiling code to extract PMU counts without performing any\n system calls, while playing nice with the kernel side.\n\n - \u0027perf bench\u0027 improvements\n\n - ... and lots of internal restructurings, cleanups and fixes that made\n these features possible.

This shift has caused a whole bunch of\ncompile problems under different config options. I attempt to\nsimplify things with the patch below.\n\nIn order to simplify things, I had to come to terms with the\nmeaning of two terms ARCH_HAS_NMI_WATCHDOG and\nCONFIG_HARDLOCKUP_DETECTOR. Basically they mean the same thing,\nthe former on a local level and the latter on a global level.\n\nWith the old x86 nmi watchdog gone, there is no need to rely on\ndefining the ARCH_HAS_NMI_WATCHDOG variable because it doesn\u0027t\nmake sense any more. x86 will now use the global\nimplementation.\n\nThe changes below do a few things. First it changes the few\nplaces that relied on ARCH_HAS_NMI_WATCHDOG to use\nCONFIG_X86_LOCAL_APIC (the former was an alias for the latter\nanyway, so nothing unusual here). Those pieces of code were\nrelying more on local apic functionality the nmi watchdog\nfunctionality, so the change should make sense.\n\nSecond, I removed the x86 implementation of\ntouch_nmi_watchdog(). It isn\u0027t need now, instead x86 will rely\non kernel/watchdog.c\u0027s implementation.\n\nThird, I removed the #define ARCH_HAS_NMI_WATCHDOG itself from\nx86. And tweaked the include/linux/nmi.h file to tell users to\nlook for an externally defined touch_nmi_watchdog in the case of\nARCH_HAS_NMI_WATCHDOG _or_ CONFIG_HARDLOCKUP_DETECTOR. This\nchanges removes some of the ugliness in that file.\n\nFinally, I added a Kconfig dependency for\nCONFIG_HARDLOCKUP_DETECTOR that said you can\u0027t have\nARCH_HAS_NMI_WATCHDOG _and_ CONFIG_HARDLOCKUP_DETECTOR. You can\nonly have one nmi_watchdog.\n\nTested with\nARCH\u003di386: allnoconfig, defconfig, allyesconfig, (various broken\nconfigs) ARCH\u003dx86_64: allnoconfig, defconfig, allyesconfig,\n(various broken configs)\n\nHopefully, after this patch I won\u0027t get any more compile broken\nemails. :-)\n\nv3:\n changed a couple of \u0027linux/nmi.h\u0027 -\u003e \u0027asm/nmi.h\u0027 to pick-up
