2013-01-18ACPI / cpuidle: Fix NULL pointer issues when cpuidle is disabledKonrad Rzeszutek Wilk
If cpuidle is disabled, that means that: per_cpu(acpi_cpuidle_device, pr->id) is set to NULL as the acpi_processor_power_init ends up failing at retval = cpuidle_register_driver(&acpi_idle_driver) (in acpi_processor_power_init) and never sets the per_cpu idle device. So when acpi_processor_hotplug on CPU online notification tries to reference said device it crashes: cpu 3 spinlock event irq 62 BUG: unable to handle kernel NULL pointer dereference at 0000000000000004 IP: [<ffffffff81381013>] acpi_processor_setup_cpuidle_cx+0x3f/0x105 PGD a259b067 PUD ab38b067 PMD 0 Oops: 0002 [#1] SMP odules linked in: dm_multipath dm_mod xen_evtchn iscsi_boot_sysfs iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi libcrc32c crc32c nouveau mxm_wmi wmi radeon ttm sg sr_mod sd_mod cdrom ata_generic ata_piix libata crc32c_intel scsi_mod atl1c i915 fbcon tileblit font bitblit softcursor drm_kms_helper video xen_blkfront xen_netfront fb_sys_fops sysimgblt sysfillrect syscopyarea xenfs xen_privcmd mperf CPU 1 Pid: 3047, comm: bash Not tainted 3.8.0-rc3upstream-00250-g165c029 #1 MSI MS-7680/H61M-P23 (MS-7680) RIP: e030:[<ffffffff81381013>] [<ffffffff81381013>] acpi_processor_setup_cpuidle_cx+0x3f/0x105 RSP: e02b:ffff88001742dca8 EFLAGS: 00010202 RAX: 0000000000010be9 RBX: ffff8800a0a61800 RCX: ffff880105380000 RDX: 0000000000000003 RSI: 0000000000000200 RDI: ffff8800a0a61800 RBP: ffff88001742dce8 R08: ffffffff81812360 R09: 0000000000000200 R10: aaaaaaaaaaaaaaaa R11: 0000000000000001 R12: ffff8800a0a61800 R13: 00000000ffffff01 R14: 0000000000000000 R15: ffffffff81a907a0 FS: 00007fd6942f7700(0000) GS:ffff880105280000(0000) knlGS:0000000000000000 CS: e033 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000004 CR3: 00000000a6773000 CR4: 0000000000042660 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process bash (pid: 3047, threadinfo ffff88001742c000, task ffff880017944000) Stack: 0000000000000150 ffff880100f59e00 ffff88001742dcd8 ffff8800a0a61800 0000000000000000 00000000ffffff01 0000000000000000 ffffffff81a907a0 ffff88001742dd18 ffffffff813815b1 ffff88001742dd08 ffffffff810ae336 Call Trace: [<ffffffff813815b1>] acpi_processor_hotplug+0x7c/0x9f [<ffffffff810ae336>] ? schedule_delayed_work_on+0x16/0x20 [<ffffffff8137ee8f>] acpi_cpu_soft_notify+0x90/0xca [<ffffffff8166023d>] notifier_call_chain+0x4d/0x70 [<ffffffff810bc369>] __raw_notifier_call_chain+0x9/0x10 [<ffffffff81094a4b>] __cpu_notify+0x1b/0x30 [<ffffffff81652cf7>] _cpu_up+0x103/0x14b [<ffffffff81652e18>] cpu_up+0xd9/0xec [<ffffffff8164a254>] store_online+0x94/0xd0 [<ffffffff814122fb>] dev_attr_store+0x1b/0x20 [<ffffffff81216404>] sysfs_write_file+0xf4/0x170 This patch fixes it.

2013-01-17ACPI / PM: Change the way power transitions to D3cold are carried outRafael J. Wysocki
During power transitions into D3cold from any shallower power states we are supposed to transition the device into D3hot and remove power from it afterward, but the current code in acpi_device_set_power() doesn't work this way. At the same time, though, we need to be careful enough to preserve backwards compatibility for systems that don't distinguish between D3hot and D3cold (e.g. designed before ACPI 4). Modify acpi_device_set_power() so that it works in accordance with the expectations in both cases. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2013-01-17ACPI: Use system level attribute of wakeup power resourcesRafael J. Wysocki
The system level attribute of ACPI power resources is the lowest system sleep level (S0, S2 etc.) in which the given resource can be "on" (ACPI 5.0, Section 7.1). On the other hand, wakeup power resources have to be "on" for devices depending on them to be able to signal wakeup. Therefore devices cannot wake up the system from sleep states higher than the minimum of the system level attributes of their wakeup power resources. Use the wakeup power resources' system level values to get the deepest system sleep state (highest system sleep level) the given device can wake up the system from. Signed-off-by: Rafael J.

2013-01-17ACPI: Take power resource initialization errors into accountRafael J. Wysocki
Some ACPI power resource initialization errors, like memory allocation errors, are not taken into account appropriately in some cases, which may lead to a device having an incomplete list of power resources that one of its power states depends on, for one example. Rework the power resource initialization and namespace scanning code so that power resource initialization errors are treated more seriously. Signed-off-by: Rafael J.

2013-01-17ACPI / scan: Consolidate extraction of power resources listsRafael J. Wysocki
The lists of ACPI power resources are currently extracted in two different ways, one for wakeup power resources and one for power resources that device power states depend on. There is no reason why it should be done differently in those two cases, so introduce a common routine for extracting power resources lists from data returned by AML, acpi_extract_power_resources(), and make the namespace scanning code use it for both wakeup and device power states power resources.

2013-01-17ACPI: Do not use device power states of power resourcesRafael J. Wysocki
ACPI power resource objects have struct acpi_device components, but they are only used for registering those resources in the device hierarchy. In particular, power state information stored in them is completely useless (amnong other things, because the power resources "devices" are not power manageable), so there is no reason for the power resources management code to keep it up to date. Remove the code updating device power states of power resources from drivers/acpi/power.c. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2013-01-17ACPI: Drop power resources driverRafael J. Wysocki
The ACPI power resources driver is not very useful, because the only thing it really does is to restore the state of the power resources that were "on" before system suspend or hibernation, but that may be achieved in a different way. Drop the ACPI power resources driver entirely and add acpi_resume_power_resources() that will walk the list of all registered power resources during system resume and turn on the ones that were "on" before the preceding system suspend or hibernation. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2013-01-17ACPI / scan: Treat power resources in a special wayRafael J. Wysocki
ACPI power resources need to be treated in a special way by the namespace scanning code, because they need to be ready to use as soon as they have been discovered (even before registering ACPI device nodes using them for power management). For this reason, it doesn't make sense to separate the preparation of struct acpi_device objects representing them in the device hierarchy from the creation of struct acpi_power_resource objects actually used for power resource manipulation. Accordingly, it doesn't make sense to define non-empty .add() and .remove() callbacks in the power resources "driver" (in fact, it is questionable whether or not it is useful to register such a "driver" at all). Rearrange the code in scan.c and power.c so that power resources are initialized entirely by one routine, acpi_add_power_resource(), that also prepares their struct acpi_device objects and registers them with the driver core, telling it to use a special release routine, acpi_release_power_resource(), for removing objects that represent power resources from memory. Make the ACPI namespace scanning code in scan.c always use acpi_add_power_resource() for preparing and registering objects that represent power resources. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2013-01-17ACPI / scan: More straightforward preparation of ACPI device objectsRafael J. Wysocki
Simplify the code preparing struct acpi_device objects for registration by removing useless code, moving different pieces of code into the functions they belong to and making a couple of int functions always returning 0 void. This also fixes a possible memory leak in ACPI device registration error code path by making acpi_device_register() detach data from device->handle if device_register() fails and prepares the scanning code for special-casing ACPI power resources (next patch).

2013-01-17ACPI / PM: Rework the handling of devices depending on power resourcesRafael J. Wysocki
Commit 0090def6 (ACPI: Add interface to register/unregister device to/from power resources) made it possible to indicate to the ACPI core that if the given device depends on any power resources, then it should be resumed as soon as all of the power resources required by it to transition to the D0 power state have been turned on. Unfortunately, however, this was a mistake, because all devices depending on power resources should be treated this way (i.e. they should be resumed when all power resources required by their D0 state have been turned on) and for the majority of those devices the ACPI core can figure out by itself which (physical) devices depend on what power resources. For this reason, replace the code added by commit 0090def6 with a new, much more straightforward, mechanism that will be used internally by the ACPI core and remove all references to that code from kernel subsystems using ACPI. For the cases when there are (physical) devices that should be resumed whenever a not directly related ACPI device node goes into D0 as a result of power resources configuration changes, like in the SATA case, add two new routines, acpi_dev_pm_add_dependent() and acpi_dev_pm_remove_dependent(), allowing subsystems to manage such dependencies. Convert the SATA subsystem to use the new functions accordingly. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

2013-01-15ACPI / scan: Add second pass to acpi_bus_trim()Rafael J. Wysocki
Make acpi_bus_trim() work in analogy with acpi_bus_scan() and carry out two passes such that ACPI drivers will be detached from device nodes being removed in the first pass and the device nodes themselves will be removed in the second pass. For this purpose split the driver unregistration out of acpi_bus_remove() into a new routine, acpi_bus_device_detach(), that will be executed by acpi_bus_trim() in the additional first pass as a post-order callback. This is necessary, because some ACPI drivers' .remove() routines unregister struct device objects associated with the ACPI device nodes being removed and that needs to happen while the ACPI device nodes are still around (for example, in case they need to be used for power management or similar things at that time).

2013-01-15ACPI / scan: Change the implementation of acpi_bus_trim()Rafael J. Wysocki
The current acpi_bus_trim() implementation is not really straightforward and may be simplified significantly by using acpi_walk_namespace() with acpi_bus_remove() as a post-order callback. Observe that acpi_bus_remove(), as called by acpi_bus_trim(), cannot actually fail, because its first argument is guaranteed not to be NULL thanks to the acpi_bus_get_device() check in acpi_bus_trim(), so simply move the acpi_bus_get_device() check to acpi_bus_remove() and use acpi_walk_namespace() to execute it for every device under start->handle as a post-order callback. The, run it directly for start->handle itself. Signed-off-by: Rafael J.

2013-01-13ACPI / PCI: Set root bridge ACPI handle in advanceRafael J. Wysocki
The ACPI handles of PCI root bridges need to be known to acpi_bind_one(), so that it can create the appropriate "firmware_node" and "physical_node" files for them, but currently the way it gets to know those handles is not exactly straightforward (to put it lightly). This is how it works, roughly: 1. acpi_bus_scan() finds the handle of a PCI root bridge, creates a struct acpi_device object for it and passes that object to acpi_pci_root_add(). 2. acpi_pci_root_add() creates a struct acpi_pci_root object, populates its "device" field with its argument's address (device->handle is the ACPI handle found in step 1). 3. The struct acpi_pci_root object created in step 2 is passed to pci_acpi_scan_root() and used to get resources that are passed to pci_create_root_bus(). 4. pci_create_root_bus() creates a struct pci_host_bridge object and passes its "dev" member to device_register(). 5. platform_notify(), which for systems with ACPI is set to acpi_platform_notify(), is called. So far, so good. Now it starts to be "interesting". 6. acpi_find_bridge_device() is used to find the ACPI handle of the given device (which is the PCI root bridge) and executes acpi_pci_find_root_bridge(), among other things, for the given device object. 7. acpi_pci_find_root_bridge() uses the name (sic!) of the given device object to extract the segment and bus numbers of the PCI root bridge and passes them to acpi_get_pci_rootbridge_handle(). 8. acpi_get_pci_rootbridge_handle() browses the list of ACPI PCI root bridges and finds the one that matches the given segment and bus numbers. Its handle is then used to initialize the ACPI handle of the PCI root bridge's device object by acpi_bind_one(). However, this is *exactly* the ACPI handle we started with in step 1. Needless to say, this is quite embarassing, but it may be avoided thanks to commit f3fd0c8 (ACPI: Allow ACPI handles of devices to be initialized in advance), which makes it possible to initialize the ACPI handle of a device before passing it to device_register(). Accordingly, add a new __weak routine, pcibios_root_bridge_prepare(), defaulting to an empty implementation that can be replaced by the interested architecutres (x86 and ia64 at the moment) with functions that will set the root bridge's ACPI handle before its dev member is passed to device_register(). Make both x86 and ia64 provide such implementations of pcibios_root_bridge_prepare() and remove acpi_pci_find_root_bridge() and acpi_get_pci_rootbridge_handle() that aren't necessary any more.

2013-01-10ACPICA: Eliminate superfluous return_UINT8 and return_UINT32 macros.Bob Moore
These macros were implemented the same as return_VALUE and thus they were not needed. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2013-01-10ACPICA: FUNCTION_TRACE macros: Check if debug is enabled up-front.Bob Moore
In the functions that implement the macros, check if debug is enabled up-front before the call to the lower debug print function. This provides a small performance improvement.

2013-01-10ACPICA: DEBUG_PRINT macros: Update to improve performance.Bob Moore
Move check for "debug enable" to before the actual call to the debug print routine. Improves time of ASLTS by about 15%. Also, remove "safe" exit macros since no complex expressions are ever used in the return statements.
