This improves diagnosis of hotplug operations\nsince an error message in a log file identifies an object that\ncaused an issue. This interface acquires the global namespace\nmutex to obtain an object path. In interrupt context, it shows\nthe object path as \u003cn/a\u003e.\n\nacpi_handle_\u003clevel\u003e() takes acpi_handle as an argument, which is\npassed to ACPI hotplug notify handlers from the ACPICA. Therefore,\nit is always available unlike other kernel objects, such as device.\n\nFor example:\n acpi_handle_err(handle, \"Device don\u0027t exist, dropping EJECT\\n\");\nlogs an error message like this at KERN_ERR.\n ACPI: \\_SB_.SCK4.CPU4: Device don\u0027t exist, dropping EJECT\n\nACPI hot-plug drivers can use acpi_handle_\u003clevel\u003e() when they need\nto identify a target ACPI object path in their messages, such as\nerror cases. The usage model is similar to dev_\u003clevel\u003e().\nacpi_handle_\u003clevel\u003e() can be used when a device is not created or\nis invalid during hot-plug operations. ACPI object path is also\nconsistent on the platform, unlike device name that gets incremented\nover hotplug operations.\n\nACPI drivers should use dev_\u003clevel\u003e() when a device object is valid.\nDevice name provides more user friendly information, and avoids\nacquiring the global ACPI namespace mutex. ACPI drivers also\ncontinue to use pr_\u003clevel\u003e() when they do not need to specify device\ninformation, such as boot-up messages.\n\nNote: ACPI_[WARNING|INFO|ERROR]() are intended for the ACPICA and\nare not associated with the kernel message level.\n\nSigned-off-by: Toshi Kani \u003ctoshi.kani@hp.com\u003e\nTested-by: Vijay Mohan Pandarathil \u003cvijaymohan.pandarathil@hp.com\u003e\nSigned-off-by: Rafael J.

This generally\nis cumbersome, time-consuming and inefficient. Moreover, it may\nbe problematic if resource conflicts need to be resolved, because\nthe different users of _CRS will need to do that in a consistent\nway. However, if there are resource conflicts, the ACPI core\nshould be able to resolve them centrally instead of relying on\nvarious users of acpi_walk_resources() to handle them correctly\ntogether.\n\nFor this reason, introduce a new function, acpi_dev_get_resources(),\nthat can be used by subsystems to obtain a list of struct resource\nobjects corresponding to the ACPI device resources returned by\n_CRS and, if necessary, to apply additional preprocessing routine\nto the ACPI resources before converting them to the struct resource\nformat.\n\nMake the ACPI code that creates platform device objects use\nacpi_dev_get_resources() for resource processing instead of executing\nacpi_walk_resources() twice by itself, which causes it to be much\nmore straightforward and easier to follow.\n\nIn the future, acpi_dev_get_resources() can be extended to meet\nthe needs of the ACPI PNP subsystem and other users of _CRS in\nthe kernel.\n\nSigned-off-by: Rafael J.

Then,\nacpi_pci_osc_control_set() will run _OSC queries in a loop until\nthe mask of _OSC control bits returned by the BIOS is equal to the\nmask passed to it. Also, before running the _OSC request\nacpi_pci_osc_control_set() will check if the caller\u0027s required\ncontrol bits are present in the final mask.\n\nUsing this mechanism we will be able to avoid situations in which the\nBIOS doesn\u0027t grant control of certain _OSC features, because they\ndepend on some other _OSC features that have not been requested.\n\nSigned-off-by: Rafael J.

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": "29b71a1ca74491fab9fed09e9d835d840d042690", "tree": "e46dc9c53e4b6266703dedc21925875cea9e4abc", "parents": [ "8c8eb78f673c07b60f31751e1e47ac367c60c6b7" ], "author": { "name": "Thomas Renninger", "email": "trenn@suse.de", "time": "Mon Jul 23 14:43:51 2007 +0200" }, "committer": { "name": "Len Brown", "email": "len.brown@intel.com", "time": "Mon Jul 23 13:56:16 2007 -0400" }, "message": "ACPI: autoload modules - Create ACPI alias interface\n\nModify modpost (file2alias.c) to add acpi*:XYZ0001: alias in modules.alias\nlike:\ngrep acpi /lib/modules/2.6.22-rc4-default/modules.alias\nalias acpi*:SNY5001:* sony_laptop\nalias acpi*:SNY6001:* sony_laptop\nfor e.g. the sony_laptop module.\nThis module matches against all ACPI devices with a HID or CID of SNY5001\nor SNY6001\n\nExport an uevent and modalias sysfs file containing the string:\n[MODALIAS\u003d]acpi:PNP0C0C:\nadditional CIDs are concatenated at the end.\n\nSigned-off-by: Thomas Renninger \u003ctrenn@suse.de\u003e\nSigned-off-by: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nSigned-off-by: Len Brown \u003clen.brown@intel.com\u003e\n" }, { "commit": "3484d79813707bb6045773953a809abba443dc20", "tree": "a986c674698face8fc51132a1feeac53fa7946a2", "parents": [ "3af044e0f832cfa3fcdce14dc30678b79dd36995" ], "author": { "name": "David Rientjes", "email": "rientjes@google.com", "time": "Sat Jul 21 17:10:32 2007 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Sat Jul 21 18:37:10 2007 -0700" }, "message": "x86_64: fake pxm-to-node mapping for fake numa\n\nFor NUMA emulation, our SLIT should represent the true NUMA topology of the\nsystem but our proximity domain to node ID mapping needs to reflect the\nemulated state.\n\nWhen NUMA emulation has successfully setup fake nodes on the system, a new\nfunction, acpi_fake_nodes() is called.
