* ACPI: Kill overly verbose "power state" log messagesRoland Dreier2009-09-271-7/+0
| | | | | | | | | | | | | | | | I was recently lucky enough to get a 64-CPU system, so my kernel log ends up with 64 lines like: ACPI: CPU0 (power states: C1[C1] C2[C3]) This is pretty useless clutter because this info is already available after boot from both /sys/devices/system/cpu/cpu*/cpuidle/state?/ as well as /proc/acpi/processor/CPU*/power. So just delete the code that prints the C-states in processor_idle.c. Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: Clarify resource conflict messageJean Delvare2009-09-271-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | The message "ACPI: Device needs an ACPI driver" is misleading. The device _may_ need an ACPI driver, if the BIOS implemented a custom API for the device in question (which, AFAIK, can't be checked.) If not, then either a generic ACPI driver may be used (for example "thermal"), or nothing can be done (other than a white list). I propose to reword the message to: ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver which I think is more correct. Comments and suggestions welcome. I also added a message warning about possible problems and system instability when users pass acpi_enforce_resources=lax, as suggested by Len.

* | ACPI: make sure every acpi_device has an IDBjorn Helgaas2009-09-251-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes sure every acpi_device has at least one ID. If we build an acpi_device for a namespace node with no _HID or _CID, we sometimes synthesize an ID like "LNXCPU" or "LNXVIDEO". If we don't even have that, give it a default "device" ID. Note that this means things like: /sys/devices/LNXSYSTM:00/LNXSYBUS:00/HWP0001:00/HWP0002:04/device:00 (a PCI slot SxFy device) will have "hid" and "modprobe" entries, where they didn't before. These aren't very useful (a HID of "device" doesn't tell you what *kind* of device it is, so it doesn't help find a driver), but I don't think they're harmful.

* | ACPI: handle re-enumeration, when acpi_devices might already existBjorn Helgaas2009-09-251-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | acpi_bus_scan() traverses the namespace to enumerate devices and uses acpi_add_single_object() to create acpi_devices. When the platform notifies us of a hot-plug event, we need to traverse part of the namespace again to figure out what appeared or disappeared. (We don't yet call acpi_bus_scan() during hot-plug, but I plan to do that in the future.) This patch makes acpi_add_single_object() notice when we already have an acpi_device, so we don't need to make a new one.

* | ACPI: factor out device type and status checkingBjorn Helgaas2009-09-251-77/+52
| | | | | | | | | | | | | | | | | | | | This patch adds acpi_bus_type_and_status(), which determines the type of the object and whether we want to build an acpi_device for it.

| | | | | | | | | | | | | | | | | | | | | | | | Add acpi_bus_get_status_handle() so we can get the status of a namespace object before building a struct acpi_device. This removes a use of "device->flags.dynamic_status", a cached indicator of whether _STA exists. It seems simpler and more reliable to just evaluate _STA and catch AE_NOT_FOUND errors.

* | ACPI: use acpi_walk_namespace() to enumerate devicesBjorn Helgaas2009-09-251-122/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | acpi_bus_scan() currently walks the namespace manually. This patch changes it to use acpi_walk_namespace() instead. Besides removing some complicated code, this means we take advantage of the namespace locking done by acpi_walk_namespace(). The locking isn't so important at boot-time, but I hope to eventually use this same path to handle hot-addition of devices, when it will be important. Note that acpi_walk_namespace() does not actually visit the starting node first, so we need to do that by hand first.

* | ACPI: identify device tree root by null parent pointer, not ACPI_BUS_TYPEBjorn Helgaas2009-09-251-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | We can identify the root of the ACPI device tree by the fact that it has no parent. This is simpler than passing around ACPI_BUS_TYPE_SYSTEM and will help remove special treatment of the device tree root. Currently, we add the root by hand with ACPI_BUS_TYPE_SYSTEM. If we traverse the tree treating the root as just another device and use acpi_get_type(), the root shows up as ACPI_TYPE_DEVICE.

* | ACPI: enumerate namespace before adding functional fixed hardware devicesBjorn Helgaas2009-09-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | This patch changes the order so we enumerate in the "root, namespace, functional fixed" order instead of the "root, functional fixed, namespace" order. When I change acpi_bus_scan() to use acpi_walk_namespace(), it will use the former order, so this patch isolates the order change for bisectability.

* | ACPI: convert acpi_bus_scan() to operate on an acpi_handleBjorn Helgaas2009-09-251-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes acpi_bus_scan() to take an acpi_handle rather than an acpi_device pointer. I plan to use acpi_bus_scan() in the hotplug path, and I'd rather not assume that notifications only go to nodes that already have acpi_devices. This will also help remove the special case for adding the root node. We currently add the root by hand before acpi_bus_scan(), but using a handle here means we can start the acpi_bus_scan() directly with the root even though it doesn't have an acpi_device yet. Note that acpi_bus_scan() currently adds and/or starts the *children* of its device argument. It doesn't do anything with the device itself.

| | | | | | | | | | | | | | | | | | | | | | This patch adds acpi_bus_get_parent(), which ascends the namespace until it finds a parent with an acpi_device. Then we use acpi_bus_get_parent() in acpi_add_single_object(), so callers don't have to figure out or keep track of the parent acpi_device.

| | | | | | | | | | | | | | | | | | | | We only pass the "type" to acpi_device_set_context() so we know whether the device has a handle to which we can attach the acpi_device pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We had two functions, acpi_os_execute_deferred() and acpi_os_execute_hp_deferred() that differed only in that the latter did acpi_os_wait_events_complete(NULL) before executing the deferred function. This patch consolidates those two functions and uses a flag in the struct acpi_os_dpc to determine whether to do the wait.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now whether the ACPI processor proc I/F is registered depends on the CONFIG_PROC. It had better depend on the CONFIG_ACPI_PROCFS. When the CONFIG_ACPI_PROCFS is unset in kernel configuration, the ACPI processor proc I/F won't be registered.
