Enumeration Type Documentation

◆ uacpi_resource_length_kind

enum uacpi_resource_length_kind

This applies to IRQ & StartDependent resources only. The DONT_CARE value is used for deserialization into the AML format to signify that the serializer is allowed to optimize the length down if possible. Note that this is generally not allowed unless the resource is generated by the caller:

– ACPI 6.5 ---------------------------------------------------------— The resource descriptors in the byte stream argument must be specified exactly as listed in the _CRS byte stream - meaning that the identical resource descriptors must appear in the identical order, resulting in a buffer of exactly the same length. Optimizations such as changing an IRQ descriptor to an IRQNoFlags descriptor (or vice-versa) must not be performed. Similarly, changing StartDependentFn to StartDependentFnNoPri

is not allowed.

		const uacpi_char *	method,

A shorthand for uacpi_get_device_resources() + uacpi_for_each_resource().

Use if you don't actually want to save the 'resources' list, but simply want to iterate it once to extract the resources you care about and then free it right away.

uacpi_status uacpi_get_resource_from_buffer	(	uacpi_data_view	aml_buffer,

Convert a single AML-encoded resource to native format.

This should be used for converting Connection() fields (passed during IO on GeneralPurposeIO or GenericSerialBus operation regions) or other similar buffers with only one resource to native format.

NOTE: the returned buffer must be released via uacpi_free_resource()

◆ uacpi_set_resources()

uacpi_status uacpi_set_resources	(	uacpi_namespace_node *	device,

Set the configuration to be used by the 'device' by calling its _SRS method.

Note that this expects 'resources' in the normal 'uacpi_resources' format, and not the raw AML resources bytestream, the conversion to the latter is done automatically by this API. If you want to _SRS a raw AML resources bytestream, use 'uacpi_execute' or similar API directly.
