* acpi: add interface to build device specific AMLIgor Mammedov2022-06-101-0/+8
| | | | | | | | | | | | | | | | | There is already ISADeviceClass::build_aml() callback which builds device specific AML blob for some ISA devices. To extend the same idea to other devices, add TYPE_ACPI_DEV_AML_IF Interface that will provide a more generic callback which will be used not only for ISA but other devices. It will allow get rid of some data-mining and ad-hoc AML building, by asking device(s) to generate its own AML blob like it's done for ISA devices.

* acpi: extend ACPI interface to provide send_event hookIgor Mammedov2016-06-071-0/+9
| | | | | | | | | | | | | send_event() hook will allow to send ACPI event in a target specific way (GPE or GPIO based impl.) it will also simplify proxy wrappers in piix4pm/ich9 that access ACPI regs and SCI which are part of piix4pm/lcp_ich9 devices and call acpi_foo() API directly.

* acpi: introduce TYPE_ACPI_DEVICE_IF interfaceIgor Mammedov2014-06-191-0/+15
... it will be used to abstract generic ACPI bits from device that implements ACPI interface. ACPIOSTInfo type is used for passing-through raw _OST event/status codes reported by guest OS to a management layer. It lets management tools interpret values as specified by ACPI spec if it is interested in it. QEMU doesn't encode these values as enum, since it doesn't need to handle them and it allows interface to scale well without any changes in QEMU while guest OS and management evolves in time.
