selects the minimum frequency that can retire\na workload with negligible idle time -- ideally resulting in the highest\nperformance/power efficiency with negligible performance impact.\n\nBut on some systems and some workloads, this algorithm\nis more performance biased than necessary, and\nde-tuning it a bit to allow some performance impact\ncan save measurable power.\n\nThis patch adds a \"powersave_bias\" tunable to ondemand\nto allow it to reduce its target frequency by a specified percent.\n\nBy default, the powersave_bias is 0 and has no effect.\npowersave_bias is in units of 0.1%, so it has an effective range\nof 1 through 1000, resulting in 0.1% to 100% impact.\n\nIn practice, users will not be able to detect a difference between\n0.1% increments, but 1.0% increments turned out to be too large.\nAlso, the max value of 1000 (100%) would simply peg the system\nin its deepest power saving P-state, unless the processor really has\na hardware P-state at 0Hz:-)\n\nFor example, If ondemand requests 2.0GHz based on utilization,\nand powersave_bias\u003d100, this code will knock 10% off the target\nand seek a target of 1.8GHz instead of 2.0GHz until the\nnext sampling. If 1.8 is an exact match with an hardware frequency\nwe use it, otherwise we average our time between the frequency\nnext higher than 1.8 and next lower than 1.8.\n\nNote that a user or administrative program can change powersave_bias\nat run-time depending on how they expect the system to be used.\n\nSigned-off-by: Venkatesh Pallipadi \u003cvenkatesh.pallipadi at intel.com\u003e\nSigned-off-by: Alexey Starikovskiy \u003calexey.y.starikovskiy at intel.com\u003e\nSigned-off-by: Dave Jones \u003cdavej@redhat.com\u003e\n" }, { "commit": "1ce28d6b19112a7c76af8e971e2de3109d19a943", "tree": "5fe089fa4b9851ca4c975a5e13f636f95fa43078", "parents": [ "cd878479792cc1e4bc9d62ed0ef2c4454743848c" ], "author": { "name": "Alexey Starikovskiy", "email": "alexey_y_starikovskiy@linux.intel.com", "time": "Mon Jul 31 22:25:20 2006 +0400" }, "committer": { "name": "Dave Jones", "email": "davej@redhat.com", "time": "Fri Aug 11 17:59:56 2006 -0400" }, "message": "[CPUFREQ][1/2] ondemand: updated tune for hardware coordination\n\nTry to make dbs_check_cpu() call on all CPUs at the same jiffy.\nThis will help when multiple cores share P-states via Hardware Coordination.\n\nSigned-off-by: Venkatesh Pallipadi \u003cvenkatesh.pallipadi at intel.com\u003e\nSigned-off-by: Alexey Starikovskiy \u003calexey.y.starikovskiy at intel.com\u003e\nSigned-off-by: Dave Jones \u003cdavej@redhat.com\u003e\n" }, { "commit": "cd878479792cc1e4bc9d62ed0ef2c4454743848c", "tree": "41abf6ff0cb2e4797fb14a31b1723371a5fda685", "parents": [ "9f737633e6ee54fc174282d49b2559bd2208391d" ], "author": { "name": "Dave Jones", "email": "davej@redhat.com", "time": "Fri Aug 11 17:59:28 2006 -0400" }, "committer": { "name": "Dave Jones", "email": "davej@redhat.com", "time": "Fri Aug 11 17:59:28 2006 -0400" }, "message": "[CPUFREQ] Fix typo.\n\nSigned-off-by: Dave Jones \u003cdavej@redhat.com\u003e\n" }, { "commit": "ea71497020c55cd39221e0abad5c1752ac6e3f47", "tree": "cd0fb594af99f384f11b0834d6302b956bfd6f15", "parents": [ "3bcb09a35641f2840bd59d8f82154f830dca282c" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Thu Jul 06 12:32:01 2006 -0700" }, "committer": { "name": "Dave Jones", "email": "davej@redhat.com", "time": "Mon Jul 31 18:37:06 2006 -0400" }, "message": "[CPUFREQ] [2/2] demand load governor modules.\n\nDemand-load cpufreq governor modules if needed.\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nSigned-off-by: Dave Jones \u003cdavej@redhat.com\u003e\n" }, { "commit": "3bcb09a35641f2840bd59d8f82154f830dca282c", "tree": "57fc63ed401b27573d88f322487a6554f006c883", "parents": [ "32deb2d5c4c291d7d9a73198dc357a151e4b978c" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Thu Jul 06 12:30:26 2006 -0700" }, "committer": { "name": "Dave Jones", "email": "davej@redhat.com", "time": "Mon Jul 31 18:37:06 2006 -0400" }, "message": "[CPUFREQ] [1/2] add __find_governor helper and clean up some error handling.\n\nAdds a __find_governor() helper function to look up a governor by\nname.

thread must honor rule #1.\n4. the policy lock and other cpufreq internal locks nest within\n the lock_cpu_hotplug() lock.\n\nI\u0027m not entirely happy about how the __cpufreq_governor rule ended up\n(conditional locking rule depending on the argument) but basically all\ncallers pass this as a constant so it\u0027s not too horrible.\n\nThe patch also removes the cpufreq_governor() function

There is no\nprotection against entries being added to or removed from a chain while the\nchain is in use. The issues were discussed in this thread:\n\n http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113018709002036\u0026w\u003d2\n\nWe noticed that notifier chains in the kernel fall into two basic usage\nclasses:\n\n\t\"Blocking\" chains are always called from a process context\n\tand the callout routines are allowed to sleep;\n\n\t\"Atomic\" chains can be called from an atomic context and\n\tthe callout routines are not allowed to sleep.\n\nWe decided to codify this distinction and make it part of the API. Therefore\nthis set of patches introduces three new, parallel APIs: one for blocking\nnotifiers, one for atomic notifiers, and one for \"raw\" notifiers (which is\nreally just the old API under a new name). New kinds of data structures are\nused for the heads of the chains, and new routines are defined for\nregistration, unregistration, and calling a chain. The three APIs are\nexplained in include/linux/notifier.h and their implementation is in\nkernel/sys.c.\n\nWith atomic and blocking chains, the implementation guarantees that the chain\nlinks will not be corrupted and that chain callers will not get messed up by\nentries being added or removed. For raw chains the implementation provides no\nguarantees at all; users of this API must provide their own protections. (The\nidea was that situations may come up where the assumptions of the atomic and\nblocking APIs are not appropriate, so it should be possible for users to\nhandle these things in their own way.)\n\nThere are some limitations, which should not be too hard to live with. For\natomic/blocking chains, registration and unregistration must always be done in\na process context since the chain is protected by a mutex/rwsem. Also, a\ncallout routine for a non-raw chain must not try to register or unregister\nentries on its own chain. (This did happen in a couple of places and the code\nhad to be changed to avoid it.)\n\nSince atomic chains may be called from within an NMI handler, they cannot use\nspinlocks for synchronization. Instead we use RCU. The overhead falls almost\nentirely in the unregister routine, which is okay since unregistration is much\nless frequent that calling a chain.\n\nHere is the list of chains that we adjusted and their classifications. None\nof them use the raw API, so for the moment it is only a placeholder.\n\n ATOMIC CHAINS\n -------------\narch/i386/kernel/traps.c:\t\ti386die_chain\narch/ia64/kernel/traps.c:\t\tia64die_chain\narch/powerpc/kernel/traps.c:\t\tpowerpc_die_chain\narch/sparc64/kernel/traps.c:\t\tsparc64die_chain\narch/x86_64/kernel/traps.c:\t\tdie_chain\ndrivers/char/ipmi/ipmi_si_intf.c:\txaction_notifier_list\nkernel/panic.c:\t\t\t\tpanic_notifier_list\nkernel/profile.c:\t\t\ttask_free_notifier\nnet/bluetooth/hci_core.c:\t\thci_notifier\nnet/ipv4/netfilter/ip_conntrack_core.c:\tip_conntrack_chain\nnet/ipv4/netfilter/ip_conntrack_core.c:\tip_conntrack_expect_chain\nnet/ipv6/addrconf.c:\t\t\tinet6addr_chain\nnet/netfilter/nf_conntrack_core.c:\tnf_conntrack_chain\nnet/netfilter/nf_conntrack_core.c:\tnf_conntrack_expect_chain\nnet/netlink/af_netlink.c:\t\tnetlink_chain\n\n BLOCKING CHAINS\n ---------------\narch/powerpc/platforms/pseries/reconfig.c:\tpSeries_reconfig_chain\narch/s390/kernel/process.c:\t\tidle_chain\narch/x86_64/kernel/process.c\t\tidle_notifier\ndrivers/base/memory.c:\t\t\tmemory_chain\ndrivers/cpufreq/cpufreq.c\t\tcpufreq_policy_notifier_list\ndrivers/cpufreq/cpufreq.c\t\tcpufreq_transition_notifier_list\ndrivers/macintosh/adb.c:\t\tadb_client_list\ndrivers/macintosh/via-pmu.c\t\tsleep_notifier_list\ndrivers/macintosh/via-pmu68k.c\t\tsleep_notifier_list\ndrivers/macintosh/windfarm_core.c\twf_client_list\ndrivers/usb/core/notify.c\t\tusb_notifier_list\ndrivers/video/fbmem.c\t\t\tfb_notifier_list\nkernel/cpu.c\t\t\t\tcpu_chain\nkernel/module.c\t\t\t\tmodule_notify_list\nkernel/profile.c\t\t\tmunmap_notifier\nkernel/profile.c\t\t\ttask_exit_notifier\nkernel/sys.c\t\t\t\treboot_notifier_list\nnet/core/dev.c\t\t\t\tnetdev_chain\nnet/decnet/dn_dev.c:\t\t\tdnaddr_chain\nnet/ipv4/devinet.c:\t\t\tinetaddr_chain\n\nIt\u0027s possible that some of these classifications are wrong.
