| * ACPI: Fix autloading of dock, video, bay and all linux specific HID driversFrank Seidel2007-12-081-15/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | References: https://bugzilla.novell.com/show_bug.cgi?id=302482 Due to the new autloading of acpi drivers, the dock driver wasn't loaded anymore as there is no HID to identify it with (dock is needed if ACPI has a _DCK method). This patch is a workaround for this, original by Thomas Renninger, revised first by Kay Sievers and last by Frank Seidel. V2 of this patch fixed problems on systems without a defined _CID for the docking devices.

* Driver core: change add_uevent_var to use a structKay Sievers2007-10-121-7/+9
| | | | | | | | | | | | | | | | | | 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 Brownell2007-05-081-1/+1
| | | | | | | | | | | | | | | | | | 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 Rui2006-12-211-9/+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.

| * | ACPI: Set fake hid for non-PNPID ACPI devicesZhang Rui2006-12-151-2/+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 = ".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add removal_type in structure acpi_device for hot removal. ACPI_BUS_REMOVAL_EJECT is used for ACPI device hot removal.

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.
