On HP Folio 13-2000, the BIOS defines a CMOS RTC Operation Region and the EC's _REG methord accesses that region. Thus an appropriate address space handler must be registered for that region before the EC driver is loaded. Introduce a mechanism for adding CMOS RTC address space handlers. Register an ACPI scan handler for CMOS RTC devices such that, when a device of that kind is detected during an ACPI namespace scan, a common CMOS RTC operation region address space handler will be installed for it.

2013-06-25libata-acpi: add back ACPI based hotplug functionalityAaron Lu3-1/+40
Commit 30dcf76acc69 "libata: migrate ACPI code over to new bindings" mistakenly dropped the code to register hotplug notificaion handler for ATA port/devices, causing regression for people using ATA bay, as kernel bug #59871 shows. Fix this by adding back the hotplug notification handler registration code. Since this code has to be run once and notification needs to be installed on every ATA port/devices handle no matter if there is actual device attached, we can't do this in binding time for ATA device ACPI handle, as the binding only occurs when a SCSI device is created, i.e. there is device attached. So introduce the ata_acpi_hotplug_init() function to loop scan all ATA ACPI handles and if it is available, install the notificaion handler for it during ATA init time. With the ATA ACPI handle binding to SCSI device tree, it is possible now that when the SCSI hotplug work removes the SCSI device, the ACPI unbind function will find that the corresponding ACPI device has already been deleted by dock driver, causing a scaring message like: [ 128.263966] scsi 4:0:0:0: Oops, 'acpi_handle' corrupt Fix this by waiting for SCSI hotplug task finish in our notificaion handler, so that the removal of ACPI device done in ACPI unbind function triggered by the removal of SCSI device is run earlier when ACPI device is still available.

2013-06-24ACPI / dock / PCI: Synchronous handling of dock events for PCI devicesRafael J. Wysocki3-58/+133
The interactions between the ACPI dock driver and the ACPI-based PCI hotplug (acpiphp) are currently problematic because of ordering issues during hot-remove operations. First of all, the current ACPI glue code expects that physical devices will always be deleted before deleting the companion ACPI device objects. Otherwise, acpi_unbind_one() will fail with a warning message printed to the kernel log, for example: [ 185.026073] usb usb5: Oops, 'acpi_handle' corrupt [ 185.035150] pci 0000:1b:00.0: Oops, 'acpi_handle' corrupt [ 185.035515] pci 0000:18:02.0: Oops, 'acpi_handle' corrupt [ 180.013656] port1: Oops, 'acpi_handle' corrupt This means, in particular, that struct pci_dev objects have to be deleted before the struct acpi_device objects they are "glued" with. Now, the following happens the during the undocking of an ACPI-based dock station: 1) hotplug_dock_devices() invokes registered hotplug callbacks to destroy physical devices associated with the ACPI device objects depending on the dock station. It calls dd->ops->handler() for each of those device objects. 2) For PCI devices dd->ops->handler() points to handle_hotplug_event_func() that queues up a separate work item to execute _handle_hotplug_event_func() for the given device and returns immediately. That work item will be executed later. 3) hotplug_dock_devices() calls dock_remove_acpi_device() for each device depending on the dock station. This runs acpi_bus_trim() for each of them, which causes the underlying ACPI device object to be destroyed, but the work items queued up by handle_hotplug_event_func() haven't been started yet. 4) _handle_hotplug_event_func() queued up in step 2) are executed and cause the above failure to happen, because the PCI devices they handle do not have the companion ACPI device objects any more (those objects have been deleted in step 3). The possible breakage doesn't end here, though, because hotplug_dock_devices() may return before at least some of the _handle_hotplug_event_func() work items spawned by it have a chance to complete and then undock() will cause _DCK to be evaluated and that will cause the devices handled by the _handle_hotplug_event_func() to go away possibly while they are being accessed. This means that dd->ops->handler() for PCI devices should not point to handle_hotplug_event_func(). Instead, it should point to a function that will do the work of _handle_hotplug_event_func() synchronously. For this reason, introduce such a function, hotplug_event_func(), and modity acpiphp_dock_ops to point to it as the handler. Unfortunately, however, this is not sufficient, because if the dock code were not changed further, hotplug_event_func() would now deadlock with hotplug_dock_devices() that called it, since it would run unregister_hotplug_dock_device() which in turn would attempt to acquire the dock station's hp_lock mutex already acquired by hotplug_dock_devices(). To resolve that deadlock use the observation that unregister_hotplug_dock_device() won't need to acquire hp_lock if PCI bridges the devices on the dock station depend on are prevented from being removed prematurely while the first loop in hotplug_dock_devices() is in progress. To make that possible, introduce a mechanism by which the callers of register_hotplug_dock_device() can provide "init" and "release" routines that will be executed, respectively, during the addition and removal of the physical device object associated with the given ACPI device handle. Make acpiphp use two new functions, acpiphp_dock_init() and acpiphp_dock_release(), that call get_bridge() and put_bridge(), respectively, on the acpiphp bridge holding the given device, for this purpose. In addition to that, remove the dock station's list of "hotplug devices" and make the dock code always walk the whole list of "dependent devices" instead in such a way that the loops in hotplug_dock_devices() and dock_event() (replacing the loops over "hotplug devices") will take references to the list entries that register_hotplug_dock_device() has been called for. That prevents the "release" routines associated with those entries from being called while the given entry is being processed and for PCI devices this means that their bridges won't be removed (by a concurrent thread) while hotplug_event_func() handling them is being executed. This change is based on two earlier patches from Jiang Liu. References: https://bugzilla.kernel.org/show_bug.cgi?id=59501 Reported-and-tested-by: Alexander E.

2013-06-23PCI / ACPI: Use boot-time resource allocation rules during hotplugJiang Liu3-6/+14
On x86 platforms, the kernel respects PCI resource assignments from the BIOS and only reassigns resources for unassigned BARs at boot time. However, with the ACPI-based hotplug (acpiphp), it ignores the BIOS' PCI resource assignments completely and reassigns all resources by itself. This causes differences in PCI resource allocation between boot time and runtime hotplug to occur, which is generally undesirable and sometimes actively breaks things. Namely, if there are enough resources, reassigning all PCI resources during runtime hotplug should work, but it may fail if the resources are constrained. This may happen, for instance, when some PCI devices with huge MMIO BARs are involved in the runtime hotplug operations, because the current PCI MMIO alignment algorithm may waste huge chunks of MMIO address space in those cases. On the Alexander's Sony VAIO VPCZ23A4R the BIOS allocates limited MMIO resources for the dock station which contains a device (graphics adapter) with a 256MB MMIO BAR. An attempt to reassign that during runtime hotplug causes the dock station MMIO window to be exhausted and acpiphp fails to allocate resources for the majority of devices on the dock station as a result. To prevent that from happening, modify acpiphp to follow the boot time resources allocation behavior so that the BIOS' resource assignments are respected during runtime hotplug too.

2013-06-23ACPI / dock: Initialize ACPI dock subsystem upfrontJiang Liu3-41/+7
Commit 3b63aaa70e1 (PCI: acpiphp: Do not use ACPI PCI subdriver mechanism) introduced an ACPI dock support regression, because it changed the relative initialization order of the ACPI dock subsystem and the ACPI-based PCI hotplug (acpiphp). Namely, the ACPI dock subsystem has to be initialized before acpiphp_enumerate_slots() is first run, which after commit 3b63aaa70e1 happens during the initial enumeration of the PCI hierarchy triggered by the initial ACPI namespace scan in acpi_scan_init(). For this reason, the dock subsystem has to be initialized before the initial ACPI namespace scan in acpi_scan_init(). To make that happen, modify the ACPI dock subsystem to be non-modular and add the invocation of its initialization routine, acpi_dock_init(), to acpi_scan_init() directly before the initial namespace scan. [rjw: Changelog, removal of dock_exit().] References: https://bugzilla.kernel.org/show_bug.cgi?id=59501 Reported-and-tested-by: Alexander E.
