* acpi/generic_event_device: add an APEI error deviceMauro Carvalho Chehab2025-10-041-0/+1
| | | | | | | | | | | | | | | | | | | Adds a generic error device to handle generic hardware error events as specified at ACPI 6.5 specification at 18.3.2.7.2: https://uefi.org/specs/ACPI/6.5/18_Platform_Error_Interfaces.html#event-notification-for-generic-error-sources using HID PNP0C33. The PNP0C33 device is used to report hardware errors to the guest via ACPI APEI Generic Hardware Error Source (GHES).

Since its removal requires include fixes in various unrelated files to keep the code compiling it has been split in a dedicated commit.

* hw/acpi/acpi_dev_interface: Remove now unused madt_cpu virtual methodBernhard Beschow2023-10-041-2/+0
| | | | | | | | | | | | | | | This virtual method was always set to the x86-specific pc_madt_cpu_entry(), even in piix4 which is also used in MIPS. The previous changes use pc_madt_cpu_entry() otherwise, so madt_cpu can be dropped. Since pc_madt_cpu_entry() is now only used in x86-specific code, the stub in hw/acpi/acpi-x86-stub can be removed as well.

* qapi: Extract ACPI commands to 'acpi.json'Philippe Mathieu-Daudé2020-09-291-1/+1
| | | | | | | | | | | | | | | | | | | Only qemu-system-FOO and qemu-storage-daemon provide QMP monitors, therefore such declarations and definitions are irrelevant for user-mode emulation. Extracting the ACPI commands to their own schema reduces the size of the qapi-misc* headers generated, and pulls less QAPI-generated code into user-mode.

* Include hw/qdev-properties.h lessMarkus Armbruster2019-08-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

* Include generated QAPI headers lessMarkus Armbruster2019-08-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the generated qapi-types-MODULE.h are included all over the place. Changing a QAPI type can trigger massive recompiling. Top scorers recompile more than 1000 out of some 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h): 6300 qapi/qapi-builtin-types.h 5700 qapi/qapi-types-run-state.h 3900 qapi/qapi-types-common.h 3300 qapi/qapi-types-sockets.h 3000 qapi/qapi-types-misc.h 3000 qapi/qapi-types-crypto.h 3000 qapi/qapi-types-job.h 3000 qapi/qapi-types-block-core.h 2800 qapi/qapi-types-block.h 1300 qapi/qapi-types-net.h Clean up headers to include generated QAPI headers only where needed. Impact is negligible except for hw/qdev-properties.h. This header includes qapi/qapi-types-block.h and qapi/qapi-types-misc.h. They are used only in expansions of property definition macros such as DEFINE_PROP_BLOCKDEV_ON_ERROR() and DEFINE_PROP_OFF_AUTO(). Moving their inclusion from hw/qdev-properties.h to the users of these macros avoids pointless recompiles. This is how other property definition macros, such as DEFINE_PROP_NETDEV(), already work. Improves things for some of the top scorers: 3600 qapi/qapi-types-common.h 2800 qapi/qapi-types-sockets.h 900 qapi/qapi-types-misc.h 2200 qapi/qapi-types-crypto.h 2100 qapi/qapi-types-job.h 2100 qapi/qapi-types-block-core.h 270 qapi/qapi-types-block.h Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Tested-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20190812052359.30071-3-armbru@redhat.com>

... 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.
