Preventing latency spikes of more than 200 microseconds for\n kernels built with NR_CPUS\u003d4096, which is reportedly becoming the\n default for some distros. This is a first step, as it does not\n help with systems that actually -have- 4096 CPUs (work on this case\n is in progress, but is not yet ready for mainline).\n\n This category also includes improving concurrency of rcu_barrier(),\n placed here due to conflicts. Posted to LKML at:\n\n https://lkml.org/lkml/2012/6/22/381\n\n Note that patches 18-22 of that series have been defered to 3.7, as\n they have not yet proven themselves to be mainline-ready (and yes,\n these are the ones intended to get rid of RCU\u0027s latency spikes for\n systems that actually have 4096 CPUs).\n\n 2. Updates to documentation and rcutorture fixes, the latter category\n including improvements to rcu_barrier() testing. Posted to LKML at\n\n http://lkml.indiana.edu/hypermail/linux/kernel/1206.1/04094.html.\n\n 3.

But Linux runs only on\n32-bit and wider CPUs. We can use that.\n\nFirst: using 32x32-\u003e64 multiply and trivial 32-bit shift, we can correctly\ndivide by 10 much larger numbers, and thus we can print groups of 9 digits\ninstead of groups of 5 digits.\n\nNext: there are two algorithms to print larger numbers. One is generic:\ndivide by 1000000000 and repeatedly print groups of (up to) 9 digits.\nIt\u0027s conceptually simple, but requires an (unsigned long long) /\n1000000000 division.\n\nSecond algorithm splits 64-bit unsigned long long into 16-bit chunks,\nmanipulates them cleverly and generates groups of 4 decimal digits. It so\nhappens that it does NOT require long long division.\n\nIf long is \u003e 32 bits, division of 64-bit values is relatively easy, and we\nwill use the first algorithm. If long long is \u003e 64 bits (strange\narchitecture with VERY large long long), second algorithm can\u0027t be used,\nand we again use the first one.\n\nElse (if long is 32 bits and long long is 64 bits) we use second one.\n\nAnd third: there is a simple optimization which takes fast path not only\nfor zero as was done before, but for all one-digit numbers.\n\nIn all tested cases new code is faster than old one, in many cases by 30%,\nin few cases by more than 50% (for example, on x86-32, conversion of\n12345678). Code growth is ~0 in 32-bit case and ~130 bytes in 64-bit\ncase.\n\nThis patch is based upon an original from Michal Nazarewicz.\n\n[akpm@linux-foundation.org: checkpatch fixes]\nSigned-off-by: Michal Nazarewicz \u003cmina86@mina86.com\u003e\nSigned-off-by: Denys Vlasenko \u003cvda.linux@googlemail.com\u003e\nCc: Douglas W Jones \u003cjones@cs.uiowa.edu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "725fe002d315c2501c110b7245d3eb4f4535f4d6", "tree": "c68759e4765673eb1f28e220edea40d84d9ff744", "parents": [ "d84970bbaf9a09b3fc60c18ee6d59bc9cb4c3b8a" ], "author": { "name": "Grant Likely", "email": "grant.likely@secretlab.ca", "time": "Thu May 31 16:26:08 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 31 17:49:27 2012 -0700" }, "message": "vsprintf: correctly handle width when \u0027#\u0027 flag used in %#p format\n\nThe \u0027%p\u0027 output of the kernel\u0027s vsprintf() uses spec.field_width to\ndetermine how many digits to output based on 2 * sizeof(void*) so that all\ndigits of a pointer are shown. ie. a pointer will be output as\n\"001A2B3C\" instead of \"1A2B3C\".

For example, if you can rely on a fast population\ncount instruction on your architecture, this will allow you to make your\noptimized \u003casm/word-at-a-time.h\u003e file with that.\n\nNOTE! The \"generic\" version in include/asm-generic/word-at-a-time.h is\nnot truly generic, it actually only works on big-endian. Why? Because\non little-endian the generic algorithms are wasteful, since you can\ninevitably do better. The x86 implementation is an example of that.\n\n(The only truly non-generic part of the asm-generic implementation is\nthe \"find_zero()\" function, and you could make a little-endian version\nof it. And if the Kbuild infrastructure allowed us to pick a particular\nheader file, that would be lovely)\n\nThe \u003casm/word-at-a-time.h\u003e functions are as follows:\n\n - WORD_AT_A_TIME_CONSTANTS: specific constants that the algorithm\n uses.\n\n - has_zero(): take a word, and determine if it has a zero byte in it.\n It gets the word, the pointer to the constant pool, and a pointer to\n an intermediate \"data\" field it can set.\n\n This is the \"quick-and-dirty\" zero tester: it\u0027s what is run inside\n the hot loops.\n\n - \"prep_zero_mask()\": take the word, the data that has_zero() produced,\n and the constant pool, and generate an *exact* mask of which byte had\n the first zero. This is run directly *outside* the loop, and allows\n the \"has_zero()\" function to answer the \"is there a zero byte\"\n question without necessarily getting exactly *which* byte is the\n first one to contain a zero.\n\n If you do multiple byte lookups concurrently (eg \"hash_name()\", which\n looks for both NUL and \u0027/\u0027 bytes), after you\u0027ve done the prep_zero_mask()\n phase, the result of those can be or\u0027ed together to get the \"either\n or\" case.\n\n - The result from \"prep_zero_mask()\" can then be fed into \"find_zero()\"\n (to find the byte offset of the first byte that was zero) or into\n \"zero_bytemask()\" (to find the bytemask of the bytes preceding the\n zero byte).\n\n The existence of zero_bytemask() is optional, and is not necessary\n for the normal string routines. But dentry name hashing needs it, so\n if you enable DENTRY_WORD_AT_A_TIME you need to expose it.\n\nThis changes the generic strncpy_from_user() function and the dentry\nhashing functions to use these modified word-at-a-time interfaces.

Posted to LKML:\n https://lkml.org/lkml/2012/4/23/322.\n\n 3) A couple of commits that improve the efficiency of the interaction\n between preemptible RCU and the scheduler, these two being all that\n survived an abortive attempt to allow preemptible RCU\u0027s\n __rcu_read_lock() to be inlined. The full set was posted to LKML at\n https://lkml.org/lkml/2012/4/14/143, and the first and third patches\n of that set remain.\n\n 4) Lai Jiangshan\u0027s algorithmic implementation of SRCU, which includes\n call_srcu() and srcu_barrier(). A major feature of this new\n implementation is that synchronize_srcu() no longer disturbs the\n execution of other CPUs. This work is based on earlier\n implementations by Peter Zijlstra and Paul E. McKenney.

Its based upon\nThomas Renninger\u0027s $module.ddebug boot-time debugging patch from\nhttps://lkml.org/lkml/2010/9/15/397\n\nThe \u0027fake\u0027 module parameter is provided for all modules, whether or\nnot they need it. It is not explicitly added to each module, but is\nimplemented in callbacks invoked from parse_args.\n\nFor builtin modules, dynamic_debug_init() now directly calls\nparse_args(..., \u0026ddebug_dyndbg_boot_params_cb), to process the params\nundeclared in the modules, just after the ddebug tables are processed.\n\nWhile its slightly weird to reprocess the boot params, parse_args() is\nalready called repeatedly by do_initcall_levels(). More importantly,\nthe dyndbg queries (given in ddebug_query or dyndbg params) cannot be\nactivated until after the ddebug tables are ready, and reusing\nparse_args is cleaner than doing an ad-hoc parse. This reparse would\nbreak options like inc_verbosity, but they probably should be params,\nlike verbosity\u003d3.\n\nddebug_dyndbg_boot_params_cb() handles both bare dyndbg (aka:\nddebug_query) and module-prefixed dyndbg params, and ignores all other\nparameters. For example, the following will enable pr_debug()s in 4\nbuiltin modules, in the order given:\n\n dyndbg\u003d\"module params +p; module aio +p\" module.dyndbg\u003d+p pci.dyndbg\n\nFor loadable modules, parse_args() in load_module() calls\nddebug_dyndbg_module_params_cb(). This handles bare dyndbg params as\npassed from modprobe, and errors on other unknown params.\n\nNote that modprobe reads /proc/cmdline, so \"modprobe foo\" grabs all\nfoo.params, strips the \"foo.\", and passes these to the kernel.\nddebug_dyndbg_module_params_cb() is again called for the unknown\nparams; it handles dyndbg, and errors on others. The \"doing\" arg\nadded previously contains the module name.\n\nFor non CONFIG_DYNAMIC_DEBUG builds, the stub function accepts\nand ignores $module.dyndbg params, other unknowns get -ENOENT.\n\nIf no param value is given (as in pci.dyndbg example above), \"+p\" is\nassumed, which enables all pr_debug callsites in the module.\n\nThe dyndbg fake parameter is not shown in /sys/module/*/parameters,\nthus it does not use any resources. Changes to it are made via the\ncontrol file.\n\nAlso change pr_info in ddebug_exec_queries to vpr_info,\nno need to see it all the time.\n\nSigned-off-by: Jim Cromie \u003cjim.cromie@gmail.com\u003e\nCC: Thomas Renninger \u003ctrenn@suse.de\u003e\nCC: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nAcked-by: Jason Baron \u003cjbaron@redhat.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" } ], "next": "b8ccd5dee776d85e29cf139c77595b7369e294bc" }
