| * | ACPI: add acpi_bus_ops in acpi_deviceLi Shaohua2006-12-151-27/+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.

| * | ACPI: convert to sysfs frameworkPatrick Mochel2006-12-151-146/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setup new sysfs framework 1. Remove /sys/firmware/acpi 2. Add ACPI device in device tree. File "eject" for every device that has _EJ0 method is moved from /sys/firmware to /sys/devices. 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.

| * | ACPI: add ACPI bus_type for driver modelPatrick Mochel2006-12-151-67/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add ACPI bus_type for Linux driver model. 1. .shutdown method is added into acpi_driver.ops needed by bus_type operations. 2. remove useless parameter 'int state' in .resume method. 3. change parameter 'int state' to 'pm_message_t state' in .suspend method. Note: The new .uevent method mark ACPI drivers by PNPID instead of by name. Udev script needs to look for "HWID=" or "COMPTID=" to load ACPI drivers as a result.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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. I audited all callers of acpi_bus_register_driver(), and except asus_acpi.c and sonypi.c (fixed in previous patches), all either ignore the return value or test only for failure (<0).

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.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
