cosmetic only Make "module name" actually match the file name. Invoke with ';' as leaving it off confuses Lindent and gcc doesn't care. Fix indentation where Lindent did get confused. Signed-off-by: Len Brown <len.brown@intel.com>

2007-01-06ACPI: use more understandable bus_id for ACPI devicesZhang Rui1-3/+3
Some of the ACPI devices use the internal fake hids which are exposed to userspace as devces' bus_id after sysfs conversion. To make it more friendly, we convert them to more understandable strings. For those devices w/o PNPids, we use "device:instance_no" as the bus_id instead of "PNPIDNON:instance_no".

2006-12-21ACPI: fix Supermicro X7DB8+ Boot regressionRui Zhang1-18/+15
http://bugzilla.kernel.org/show_bug.cgi?id=7695 Originally we converted bind/unbind to use a new pci bridge driver. The driver will add/remove _PRT, so we can eventually remove .bind/.unbind methods. But we found that some of the _ADR-Based devices don't have _PRT, i.e. they are not managed by the new ACPI PCI bridge driver. So that .bind method is not called for some _ADR-Based devices, which leads to a failure. Now we make ACPI PCI Root Bridge Driver scan and binds all _ADR-Based devices once the driver is loaded, in the .add method of ACPI PCI Root Bridge driver. Extra code path for calling .bind/.unbind when _ADR-Based devices are hot added/removed is also added. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2006-12-21ACPI: use PNPID:instance_no as bus_id of ACPI deviceZhang Rui1-9/+109
Previously we used the device name in the DSDT, but would crash upon encountering a duplicate. Also, exposing the DSDT device name to the user in a patch isn't a good idea, because it is arbitrary. After some discussion, we finally decided to use "PNPID:instance_no" as the bus_id of ACPI devices. Two attributes for each device are added at the same time, the full pathname in ACPI namespace and hardware_id if it has. NOTE: acpi_bus_id_list is used to keep the information of PNPID and instance number of the given PNPID. Loop the acpi_bus_id_list to find the instance_no of the same PNPID when register a device. If failed, i.e. we don't have a node with this PNPID, allocate one and link it to this list. NOTE: Now I don't take the memory free work in charge. If necessary, I can add a reference count in struct acpi_device_bus_id, and check the reference and when unregister a device, i.e. memory is freed when the reference count of a given PNPID is 0.

2006-12-16ACPI: Set fake hid for non-PNPID ACPI devicesZhang Rui1-2/+57
We do this mainly because: 1. hid is used to match ACPI devices and drivers. .match method which is incompatible to driver model can be deleted from acpi_driver.ops then. 2. As the .uevent method mark ACPI drivers by PNPID, fake hid is set to non-PNPID devices so that udev script can load the right ACPI driver by looking for "HWID = " or "COMPTID = ".

2006-12-16ACPI: Convert ACPI PCI .bind/.unbind to use PCI bridge driverLi Shaohua1-17/+0
acpi_device had a .bind/.unbind methods, but Linux driver model does not. Cut ACPI PCI code over to use the Linux driver model methods. Convert bind/unbind to use a new pci bridge driver. The driver will add/remove _PRT, so we can eventually remove .bind/.unbind methods. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2006-12-16ACPI: add acpi_bus_removal_type in acpi_deviceLi Shaohua1-2/+4
Add removal_type in structure acpi_device for hot removal. ACPI_BUS_REMOVAL_EJECT is used for ACPI device hot removal. Only one parameter is allowed in .remove method due to driver model. So removal_type is added to indicate different removal type. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2006-12-16ACPI: add acpi_bus_ops in acpi_deviceLi Shaohua1-27/+28
Add acpi_bus_ops in acpi_device to support acpi hot plug. NOTE: Two methods .add and .start in acpi_driver.ops are called separately to probe ACPI devices, while only .probe method is called in driver model. As executing .add and .start separately is critical for ACPI device hot plug, we use acpi_bus_ops to distinguish different code path.

Operation on this file is exactly the same as before. i.e. echo 1 to "eject" will cause hot removal of this device. Corresponding changes should be made in userspace for hot removal.

2006-05-14ACPI: acpi_bus_unregister_driver() returns voidBjorn Helgaas1-22/+10
Nobody looks at the return value, and this brings it into line with pci_unregister_driver(), etc. Also removed validation of the driver pointer passed in to register and unregister. More consistent, and we'll find bugs faster if we fault rather than returning an error that's ignored. Also makes internal functions acpi_device_unregister() and acpi_driver_detach() void, since nobody uses their returns either.

acpi_bus_register_driver() should not return the number of devices claimed. We're not asking to find devices, we're making a driver available to devices, including hot-pluggable devices that may appear in the future.

2005-12-10[ACPI] ACPICA 20051117Bob Moore1-1/+1
Fixed a problem in the AML parser where the method thread count could be decremented below zero if any errors occurred during the method parse phase. This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines. This also fixed a related regression with the mechanism that detects and corrects methods that cannot properly handle reentrancy (related to the deployment of the new OwnerId mechanism.) Eliminated the pre-parsing of control methods (to detect errors) during table load. Related to the problem above, this was causing unwind issues if any errors occurred during the parse, and it seemed to be overkill. A table load should not be aborted if there are problems with any single control method, thus rendering this feature rather pointless. Fixed a problem with the new table-driven resource manager where an internal buffer overflow could occur for small resource templates. Implemented a new external interface, acpi_get_vendor_resource() This interface will find and return a vendor-defined resource descriptor within a _CRS or _PRS method via an ACPI 3.0 UUID match. (from Bjorn Helgaas) Removed the length limit (200) on string objects as per the upcoming ACPI 3.0A specification. This affects the following areas of the interpreter: 1) any implicit conversion of a Buffer to a String, 2) a String object result of the ASL Concatentate operator, 3) the String object result of the ASL ToString operator.
