To solve this:\n\n- I\u0027ve added a \u0027domain distance\u0027 function, which is used to cache\n measurement results. Each distance is only measured once. This means\n that e.g. on NUMA distances of 0, 1 and 2 might be measured, on HT\n distances 0 and 1, and on SMP distance 0 is measured. The code walks\n the domain tree to determine the distance, so it automatically follows\n whatever hierarchy an architecture sets up. This cuts down on the boot\n time significantly and removes the O(N^2) limit. The only assumption\n is that migration costs can be expressed as a function of domain\n distance - this covers the overwhelming majority of existing systems,\n and is a good guess even for more assymetric systems.\n\n [ People hacking systems that have assymetries that break this\n assumption (e.g. different CPU speeds) should experiment a bit with\n the cpu_distance() function. Adding a -\u003emigration_distance factor to\n the domain structure would be one possible solution - but lets first\n see the problem systems, if they exist at all. Lets not overdesign. ]\n\nAnother problem was that only a single cache-size was used for measuring\nthe cost of migration, and most architectures didnt set that variable\nup. Furthermore, a single cache-size does not fit NUMA hierarchies with\nL3 caches and does not fit HT setups, where different CPUs will often\nhave different \u0027effective cache sizes\u0027. To solve this problem:\n\n- Instead of relying on a single cache-size provided by the platform and\n sticking to it, the code now auto-detects the \u0027effective migration\n cost\u0027 between two measured CPUs, via iterating through a wide range of\n cachesizes. The code searches for the maximum migration cost, which\n occurs when the working set of the test-workload falls just below the\n \u0027effective cache size\u0027. I.e. real-life optimized search is done for\n the maximum migration cost, between two real CPUs.\n\n This, amongst other things, has the positive effect hat if e.g. two\n CPUs share a L2/L3 cache, a different (and accurate) migration cost\n will be found than between two CPUs on the same system that dont share\n any caches.\n\n(The reliable measurement of migration costs is tricky - see the source\nfor details.)\n\nFurthermore i\u0027ve added various boot-time options to override/tune\nmigration behavior.\n\nFirstly, there\u0027s a blanket override for autodetection:\n\n\tmigration_cost\u003d1000,2000,3000\n\nwill override the depth 0/1/2 values with 1msec/2msec/3msec values.\n\nSecondly, there\u0027s a global factor that can be used to increase (or\ndecrease) the autodetected values:\n\n\tmigration_factor\u003d120\n\nwill increase the autodetected values by 20%. This option is useful to\ntune things in a workload-dependent way - e.g. if a workload is\ncache-insensitive then CPU utilization can be maximized by specifying\nmigration_factor\u003d0.\n\nI\u0027ve tested the autodetection code quite extensively on x86, on 3\nP3/Xeon/2MB, and the autodetected values look pretty good:\n\nDual Celeron (128K L2 cache):\n\n ---------------------\n migration cost matrix (max_cache_size: 131072, cpu: 467 MHz):\n ---------------------\n [00] [01]\n [00]: - 1.7(1)\n [01]: 1.7(1) -\n ---------------------\n cacheflush times [2]: 0.0 (0) 1.7 (1784008)\n ---------------------\n\nHere the slow memory subsystem dominates system performance, and even\nthough caches are small, the migration cost is 1.7 msecs.\n\nDual HT P4 (512K L2 cache):\n\n ---------------------\n migration cost matrix (max_cache_size: 524288, cpu: 2379 MHz):\n ---------------------\n [00] [01] [02] [03]\n [00]: - 0.4(1) 0.0(0) 0.4(1)\n [01]: 0.4(1) - 0.4(1) 0.0(0)\n [02]: 0.0(0) 0.4(1) - 0.4(1)\n [03]: 0.4(1) 0.0(0) 0.4(1) -\n ---------------------\n cacheflush times [2]: 0.0 (33900) 0.4 (448514)\n ---------------------\n\nHere it can be seen that there is no migration cost between two HT\nsiblings (CPU#0/2 and CPU#1/3 are separate physical CPUs). A fast memory\nsystem makes inter-physical-CPU migration pretty cheap: 0.4 msecs.\n\n8-way P3/Xeon [2MB L2 cache]:\n\n ---------------------\n migration cost matrix (max_cache_size: 2097152, cpu: 700 MHz):\n ---------------------\n [00] [01] [02] [03] [04] [05] [06] [07]\n [00]: - 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1)\n [01]: 19.2(1) - 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1)\n [02]: 19.2(1) 19.2(1) - 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1)\n [03]: 19.2(1) 19.2(1) 19.2(1) - 19.2(1) 19.2(1) 19.2(1) 19.2(1)\n [04]: 19.2(1) 19.2(1) 19.2(1) 19.2(1) - 19.2(1) 19.2(1) 19.2(1)\n [05]: 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1) - 19.2(1) 19.2(1)\n [06]: 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1) - 19.2(1)\n [07]: 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1) 19.2(1) -\n ---------------------\n cacheflush times [2]: 0.0 (0) 19.2 (19281756)\n ---------------------\n\nThis one has huge caches and a relatively slow memory subsystem - so the\nmigration cost is 19 msecs.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Ashok Raj \u003cashok.raj@intel.com\u003e\nSigned-off-by: Ken Chen \u003ckenneth.w.chen@intel.com\u003e\nCc: \u003cwilder@us.ibm.com\u003e\nSigned-off-by: John Hawkes \u003chawkes@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c9db4fa11526affde83603fe52595bd1260c1354", "tree": "3064d71209b32569cfbd5dd0907fbe65bcf02d5e", "parents": [ "e2787630c1abb075c935cf47e91beb7c656f48c4" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Thu Jan 12 11:47:34 2006 +0100" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Thu Jan 12 11:47:34 2006 +0100" }, "message": "[hrtimer] Enforce resolution as lower limit of intervals\n\nRoman Zippel pointed out that the missing lower limit of intervals\nleads to an accounting error in the overrun count.

It is expected that /sbin/halt -p works exactly like\n/sbin/halt, when the kernel does not implement power off functionality.\n\nThe kernel can do a lot of work in the reboot notifiers and in\ndevice_shutdown before we even get to machine_power_off. Some of that\nshutdown is not safe if you are leaving the power on, and it definitely\ngets in the way of using sysrq or pressing ctrl-alt-del. Since the\nshutdown happens in generic code there is no way to fix this in\narchitecture specific code :(\n\nSome machines are kernel oopsing today because of this.\n\nThe simple solution is to turn LINUX_REBOOT_CMD_POWER_OFF into\nLINUX_REBOOT_CMD_HALT if power_off functionality is not implemented.\n\nThis has the unfortunate side effect of disabling the power off\nfunctionality on architectures that leave pm_power_off to null and still\nimplement something in machine_power_off. And it will break the build on\nsome architectures that don\u0027t have a pm_power_off variable at all.\n\nOn both counts I say tough.\n\nFor architectures like alpha that don\u0027t implement the pm_power_off variable\npm_power_off is declared in linux/pm.h and it is a generic part of our\npower management code, and all architectures should implement it.\n\nFor architectures like parisc that have a default power off method in\nmachine_power_off if pm_power_off is not implemented or fails. It is easy\nenough to set the pm_power_off variable. And nothing bad happens there,\nthe machines just stop powering off.\n\nThe current semantics are impossible without a flag at the top level so we\ncan avoid the problem code if a power off is not implemented. pm_power_off\nis as good a flag as any with the bonus that it works without modification\non at least x86, x86_64, powerpc, and ppc today.\n\nAndrew can you pick this up and put this in the mm tree. Kernels that\ndon\u0027t compile or don\u0027t power off seem saner than kernels that oops or\npanic. Until we get the arch specific patches for the problem\narchitectures this probably isn\u0027t smart to push into the stable kernel.\nUnfortunately I don\u0027t have the time at the moment to walk through every\narchitecture and make them work.

This was undesirable, as users invoking memory page\nmigration exected to happen when the placement changed, not some unspecified\ntime later when the task needed more memory.\n\nIt is now trivial to handle the page migration at the same time as the per-vma\nrebinding is done.\n\nThe routine cpuset.c:update_nodemask(), which handles changing a cpusets\nmemory placement (\u0027mems\u0027) now checks for the special case of being asked to\nwrite a placement that is the same as before.
