* ACPICA: Major update for acpi_get_object_info external interfaceBob Moore2009-08-271-4/+1
| | | | | | | | | | | | | | | | | | Completed a major update for the acpi_get_object_info external interface. Changes include: - Support for variable, unlimited length HID, UID, and CID strings - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.) - Call the _SxW power methods on behalf of a device object - Determine if a device is a PCI root bridge - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO. These changes will require an update to all callers of this interface. See the ACPICA Programmer Reference for details. Also, update all invocations of acpi_get_object_info interface Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ide: fix resume for CONFIG_BLK_DEV_IDEACPI=yBartlomiej Zolnierkiewicz2009-06-301-30/+7
| | | | | | | | | | | | | | | | | | | | | commit 2f0d0fd2a605666d38e290c5c0d2907484352dc4 ("ide-acpi: cleanup do_drive_get_GTF()") didn't account for the lack of hwif->acpidata check in generic_ide_suspend() [ indirect user of do_drive_get_GTF() through ide_acpi_exec_tfs() ] resulting in broken resume when ACPI support is enabled but ACPI data is unavailable. Fix it by adding ide_port_acpi() helper for checking if port needs ACPI handling and cleaning generic_ide_{suspend,resume}() to use it instead of hiding hwif->acpidata and ide_noacpi checks in IDE ACPI helpers (this should help in preventing similar bugs in the future).

* ide: simplify 'struct ide_taskfile'Sergei Shtylyov2009-04-081-1/+1
| | | | | | | | | | | | Make 'struct ide_taskfile' cover only 8 register values and thus put two such fields ('tf' and 'hob') into 'struct ide_cmd', dropping unnecessary 'tf_array' field from it. This required changing the prototype of ide_get_lba_addr() and ide_tf_dump().

* ACPI support for IDE devicesHannes Reinecke2007-02-071-0/+696
This patch implements ACPI integration for generic IDE devices. The ACPI spec mandates that some methods are called during suspend and resume. And consequently there most modern Laptops cannot resume properly without it. According to the spec, we should call '_GTM' (Get Timing) upon suspend to store the current IDE adapter settings. Upon resume we should call '_STM' (Set Timing) to initialize the adapter with the stored settings; afterwards '_GTF' (Get Taskfile) should be called which returns a buffer with some IDE initialisation commands. Those commands should be passed to the drive. There are two module params which control the behaviour of this patch: 'ide=noacpi' Do not call any ACPI methods (Disables any ACPI method calls) 'ide=acpigtf' Enable execution of _GTF methods upon resume. Has no effect if 'ide=noacpi' is set. 'ide=acpionboot' Enable execution of ACPI methods during boot. This might be required on some machines if 'ide=acpigtf' is selected as some machines modify the _GTF information depending on the drive identification passed down with _STM.
