* ACPI: EC: Enable boot EC before bus_scanAlexey Starikovskiy2008-01-01
| | | | | | | | | | | Some _STA methods called during bus_scan() might require EC region handler, which might be enabled later in the scan. Enable it explicitly before scan to avoid errors.

* Driver core: change add_uevent_var to use a structKay Sievers2007-10-12
| | | | | | | | | | | | | | | | | | This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

* PNPACPI sets pnpdev->dev.archdataDavid Brownell2007-05-08
| | | | | | | | | | | | | | | | | | Teach PNPACPI how to hook up its devices to their ACPI nodes, so that pnpdev->dev.archdata points to the parallel acpi device node. Previously this only worked for PCI, leaving a notable hole. Export "acpi_bus_type" so this can work. Remove some extraneous whitespace.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

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>
| * | ACPI: use PNPID:instance_no as bus_id of ACPI deviceZhang Rui2006-12-21

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.

| * | ACPI: Set fake hid for non-PNPID ACPI devicesZhang Rui2006-12-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 = ".

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.
