It offers a similar functionality like\nrequest_region and let drivers which are known to possibly use the same IO\nports and Memory which are also often used by ACPI (hwmon and i2c) check for\nACPI interference.\n\nA boot parameter acpi_enforce_resources\u003dstrict/lax/no is provided, which\nis default set to lax:\n - strict: let conflicting drivers fail to load with an error message\n - lax: let conflicting driver work normal with a warning message\n - no: no functional change at all\nDepending on the feedback and the kind of interferences we see, this\nshould be set to strict at later time.\n\nGoal of this patch set is:\n - Identify ACPI interferences in bug reports (very hard to reproduce\n and to identify)\n - Find BIOSes for that an ACPI driver should exist for specific HW\n instead of a native one.\n - stability in general\n\nProvide acpi_check_{mem_}region.\n\nDrivers can additionally check against possible ACPI interference by also\ninvoking this shortly before they call request_region.\nIf -EBUSY is returned, the driver must not load.\nUse acpi_enforce_resources\u003dstrict/lax/no options to:\n - strict: let conflicting drivers fail to load with an error message\n - lax: let conflicting driver work normal with a warning message\n - no: no functional change at all\n\nCc: \"Mark M.

I call it the \u0027menu\u0027 governor because it\n considers the full list of idle states before each entry.\n\n I\u0027ve kept the implementation fairly simple. It attempts to guess the\n next residency time and then chooses a state that would meet at least\n the break-even point between power savings and entry cost. To this end,\n it selects the deepest idle state that satisfies the following\n constraints:\n 1. If the idle time elapsed since bus master activity was detected\n is below a threshold (currently 20 ms), then limit the selection\n to C2-type or above.\n 2. Do not choose a state with a break-even residency that exceeds\n the expected time remaining until the next timer interrupt.\n 3. Do not choose a state with a break-even residency that exceeds\n the elapsed time between the last pair of break events,\n excluding timer interrupts.\n\n This governor has an advantage over \"ladder\" governor because it\n proactively checks how much time remains until the next timer interrupt\n using the tick infrastructure. Also, it handles device interrupt\n activity more intelligently by not including timer interrupts in break\n event calculations. Finally, it doesn\u0027t make policy decisions using the\n number of state entries, which can have variable residency times (NO_HZ\n makes these potentially very large), and instead only considers sleep\n time deltas.\n\n The menu governor can be selected during runtime using the cpuidle sysfs\n interface like so:\n \"echo \"menu\" \u003e /sys/devices/system/cpu/cpuidle/current_governor\"\n\n Signed-off-by: Adam Belay \u003cabelay@novell.com\u003e\n Signed-off-by: Len Brown \u003clen.brown@intel.com\u003e\n\ncommit a4bec7e65aa3b7488b879d971651cc99a6c410fe\nAuthor: Adam Belay \u003cabelay@novell.com\u003e\nDate: Sat Mar 24 03:47:03 2007 -0400\n\n cpuidle: export time until next timer interrupt using NO_HZ\n\n Expose information about the time remaining until the next\n timer interrupt expires by utilizing the dynticks infrastructure.\n Also modify the main idle loop to allow dynticks to handle\n non-interrupt break events (e.g. DMA).

Drivers\n can be generic or particular to specific hardware/platform\n * allows pluging in multiple policy governors that can take idle state policy\n decision\n * The core also has a set of sysfs interfaces with which administrato can know\n about supported drivers and governors and switch them at run time.\n\n Signed-off-by: Adam Belay \u003cabelay@novell.com\u003e\n Signed-off-by: Shaohua Li \u003cshaohua.li@intel.com\u003e\n Signed-off-by: Venkatesh Pallipadi \u003cvenkatesh.pallipadi@intel.com\u003e\n Signed-off-by: Len Brown \u003clen.brown@intel.com\u003e\n\nSigned-off-by: Len Brown \u003clen.brown@intel.com\u003e\n" }, { "commit": "1855256c497ecfefc730df6032243f26855ce52c", "tree": "b73947f1a5e1b798e1dec068ac1cda25ae910bf6", "parents": [ "bbf25010f1a6b761914430f5fca081ec8c7accd1" ], "author": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Wed Oct 03 15:15:40 2007 -0400" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Tue Oct 09 20:22:20 2007 -0400" }, "message": "drivers/firmware: const-ify DMI API and internals\n\nThree main sets of changes:\n\n1) dmi_get_system_info() return value should have been marked const,\n since callers should not be changing that data.\n\n2) const-ify DMI internals, since DMI firmware tables should,\n whenever possible, be marked const to ensure we never ever write to\n that data area.\n\n3) const-ify DMI API, to enable marking tables const where possible\n in low-level drivers.\n\nAnd if we\u0027re really lucky, this might enable some additional\noptimizations on the part of the compiler.\n\nThe bulk of the changes are #2 and #3, which are interrelated. #1 could\nhave been a separate patch, but it was so small compared to the others,\nit was easier to roll it into this changeset.\n\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n" }, { "commit": "b4b613fd83853f8c688b3de20ab1a42331257975", "tree": "3eee8c81bda9e32cd80631bcb77b9401c6e0fa3c", "parents": [ "5e16e3f0e24dadb79b96b6134cd3303f0d42f0c5", "3c6394c5bd04e31d40d007af8b6c2484a08838d0" ], "author": { "name": "Len Brown", "email": "len.brown@intel.com", "time": "Sun Jul 22 02:29:41 2007 -0400" }, "committer": { "name": "Len Brown", "email": "len.brown@intel.com", "time": "Sun Jul 22 02:29:41 2007 -0400" }, "message": "Pull osi into release branch\n" }, { "commit": "20c2df83d25c6a95affe6157a4c9cac4cf5ffaac", "tree": "415c4453d2b17a50abe7a3e515177e1fa337bd67", "parents": [ "64fb98fc40738ae1a98bcea9ca3145b89fb71524" ], "author": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Fri Jul 20 10:11:58 2007 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Fri Jul 20 10:11:58 2007 +0900" }, "message": "mm: Remove slab destructors from kmem_cache_create().\n\nSlab destructors were no longer supported after Christoph\u0027s\nc59def9f222d44bb7e2f0a559f2906191a0862d7 change.

All\nnotify events are deferred, thus we see increase in memory consumption\nnoticed by author of the thread. Also as GPE handling is bloked,\nmachines overheat. Eventually by external poll of the same\nacpi_evaluate, kacpid is released and all the queued notify events are\nfree to run, thus 100% cpu utilization by kacpid for several seconds\nor more.\n\nTo prevent all these horrors it\u0027s needed to not put notify events to\nkacpid workqueue by either executing them immediately or putting them\non some other thread. It\u0027s dangerous to execute notify events in\nplace, as it will put several ACPI interpreter stacks on top of each\nother (at least 4 in case of nx6125), thus causing kernel stack\noverflow.\n\nFirst attempt to create a new thread was done by Peter Wainwright\nHe created a bunch of threads, which were stealing work from a kacpid\nworkqueue.\nThis patch appeared in 2.6.15 kernel shipped with Ubuntu 6.06 LTS.\n\nSecond attempt was done by me, I created a new thread for each Notify\nevent. This worked OK on HP nx machines, but broke Linus\u0027 Compaq\nn620c, by producing threads with a speed what they stopped the machine\ncompletely. Thus this patch was reverted from 18-rc2 as I remember.\nI re-made the patch to create second workqueue just for notify events,\nthus hopping it will not break Linus\u0027 machine. Patch was tested on the\nsame HP nx machines in #5534 and #7122, but I did not received reply\nfrom Linus on a test patch sent to him.\nPatch went to 19-rc and was rejected with much fanfare again.\nThere was 4th patch, which inserted schedule_timeout(1) into deferred\nexecution of kacpid, if we had any notify requests pending, but Linus\ndecided that it was too complex (involved either changes to workqueue\nto see if it\u0027s empty or atomic inc/dec).\nNow you see last variant which adds yield() to every GPE execution.\n\nhttp://bugzilla.kernel.org/show_bug.cgi?id\u003d5534\nhttp://bugzilla.kernel.org/show_bug.cgi?id\u003d8385\n\nSigned-off-by: Alexey Starikovskiy

Special\ninitiators exist for the non-auto-release case (ending in _NAR).\n\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "b976fe19acc565e5137e6f12af7b6633a23e6b7c", "tree": "f5bd7eecbee3c165ff97ab8c642cae4f421a3cec", "parents": [ "808dbbb6bb61173bf52946a28f99089d2efa4c55" ], "author": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Fri Nov 17 19:31:09 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Fri Nov 17 19:31:09 2006 -0800" }, "message": "Revert \"ACPI: created a dedicated workqueue for notify() execution\"\n\nThis reverts commit 37605a6900f6b4d886d995751fcfeef88c4e462c.\n\nAgain.\n\nThis same bug has now been introduced twice: it was done earlier by\ncommit b8d35192c55fb055792ff0641408eaaec7c88988, only to be reverted\nlast time in commit 72945b2b90a5554975b8f72673ab7139d232a121.\n\nWe must NOT try to queue up notify handlers to another thread than the\nnormal ACPI execution thread, because the notifications on some systems\nseem to just keep on accumulating until we run out of memory and/or\nthreads.\n\nKeeping events within the one deferred execution thread automatically\nthrottles the events properly.\n\nAt least the Compaq N620c will lock up completely on the first thermal\nevent without this patch reverted.\n\nCc: David Brownell \u003cdavid-b@pacbell.net\u003e\nCc: Len Brown \u003clen.brown@intel.com\u003e\nCc: Alexey Starikovskiy \u003calexey.y.starikovskiy@linux.intel.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "50dd096973f1d95aa03c6a6d9e148d706b62b68e", "tree": "1f047b9c574672c133559922af5d4aee2816b9ae", "parents": [ "b4bd8c66435a8cdf8c90334fb3b517a23ff2ab95" ], "author": { "name": "Jan Engelhardt", "email": "jengelh@linux01.gwdg.de", "time": "Sun Oct 01 00:28:50 2006 +0200" }, "committer": { "name": "Len Brown", "email": "len.brown@intel.com", "time": "Sat Oct 14 01:51:07 2006 -0400" }, "message": "ACPI: Remove unnecessary from/to-void* and to-void casts in drivers/acpi\n\nSigned-off-by: Jan Engelhardt \u003cjengelh@gmx.de\u003e\nSigned-off-by: Len Brown \u003clen.brown@intel.com\u003e\n" }, { "commit": "37605a6900f6b4d886d995751fcfeef88c4e462c", "tree": "97c0452d730c16e7e80f0062d776bdcee2446851", "parents": [ "fcfc638c6b1345b6646523dbab0065b36a868ffc" ], "author": { "name": "Alexey Y.

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386. I\u0027ve runtested the\nmain part of the code on FRV and i386, though I can\u0027t test most of the drivers.\nI\u0027ve also done partial conversion for powerpc and MIPS - these at least compile\nwith minimal configurations.\n\nThis will affect all archs. Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely. The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does\n something different depending on whether it\u0027s been supplied with a regs\n pointer or not.\n\n (*) Various IRQ handler function pointers have been moved to type\n irq_handler_t.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)\n" } ], "next": "1a1d92c10dd24bbdc28b3d6e2d03ec199dd3a65b" }
