class Manager

Defined at line 32 of file ../../src/devices/board/lib/acpi/manager.h

Class that manages ACPI device discovery and publishing.

Public Methods

acpi::status<> DiscoverDevices ()

Walk the ACPI tree, keeping track of each device that's found.

Defined at line 26 of file ../../src/devices/board/lib/acpi/manager.cc

void Manager (Acpi * acpi, iommu::IommuManagerInterface * iommu, zx_device_t * acpi_root)

Construct a new manager.

|acpi| should be a pointer to the ACPI implementation to use. The caller keeps ownership and

must ensure it outlives the manager.

|iommu| should be a pointer to the IOMMU manager implementation. The caller keeps ownership and

must ensure it outlives the manager.

|acpi_root| is a pointer to the device that will be the parent of all other ACPI devices. It

should be owned by the DDK, and must outlive the manager.

uint32_t GetNextCompositeId (std::string composite)

Get next unique ID for the enumerated composite.

Defined at line 143 of file ../../src/devices/board/lib/acpi/manager.cc

const PowerResource * AddPowerResource (ACPI_HANDLE power_resource_handle)

Used by a device to inform the manager about the existence of a power resource.

Defined at line 149 of file ../../src/devices/board/lib/acpi/manager.cc

zx_status_t ReferencePowerResources (const std::vector<ACPI_HANDLE> & power_resource_handles)

Used by a device to declare that it requires a list of power resources to be on.

The list of power resources should be sorted by ascending resource_order.

Defined at line 164 of file ../../src/devices/board/lib/acpi/manager.cc

zx_status_t DereferencePowerResources (const std::vector<ACPI_HANDLE> & power_resource_handles)

Used by a device to declare that it no longer requires a list of power resources to be on.

The list of power resources should be sorted by ascending resource_order.

Defined at line 187 of file ../../src/devices/board/lib/acpi/manager.cc

DeviceBuilder * LookupDevice (ACPI_HANDLE handle)

For internal and unit test use only.
