| # @FirmwareOSInterface: |

| # |
| # @bios: Traditional x86 BIOS interface. For example, firmware built |
| # from the SeaBIOS project usually provides this interface. |
| # |
| # @openfirmware: The interface is defined by the (historical) IEEE |
| # 1275-1994 standard. Examples for firmware projects that |
| # provide this interface are: OpenBIOS and SLOF. |
| # |
| # @uboot: Firmware interface defined by the U-Boot project. |

| # @uefi: Firmware interface defined by the UEFI specification. For |
| # example, firmware built from the edk2 (EFI Development Kit II) |
| # project usually provides this interface. |

| # |
| # @kernel: The firmware is to be loaded like a Linux kernel. This is |

| # which is especially useful for versioned machine types. |

| # |
| # @acpi-s3: The firmware supports S3 sleep (suspend to RAM), as defined |
| # in the ACPI specification. On the "pc-i440fx-*" machine |
| # types of the @i386 and @x86_64 emulation targets, S3 can be |
| # enabled with "-global PIIX4_PM.disable_s3=0" and disabled |
| # with "-global PIIX4_PM.disable_s3=1". On the "pc-q35-*" |
| # machine types of the @i386 and @x86_64 emulation targets, S3 |
| # can be enabled with "-global ICH9-LPC.disable_s3=0" and |
| # disabled with "-global ICH9-LPC.disable_s3=1". |
| # |
| # @acpi-s4: The firmware supports S4 hibernation (suspend to disk), as |
| # defined in the ACPI specification. On the "pc-i440fx-*" |
| # machine types of the @i386 and @x86_64 emulation targets, S4 |
| # can be enabled with "-global PIIX4_PM.disable_s4=0" and |
| # disabled with "-global PIIX4_PM.disable_s4=1". On the |
| # "pc-q35-*" machine types of the @i386 and @x86_64 emulation |
| # targets, S4 can be enabled with "-global |
| # ICH9-LPC.disable_s4=0" and disabled with "-global |
| # ICH9-LPC.disable_s4=1". |
| # |
| # @amd-sev: The firmware supports running under AMD Secure Encrypted |
| # Virtualization, as specified in the AMD64 Architecture |
| # Programmer's Manual. QEMU command line options related to |
| # this feature are documented in |
| # "docs/system/i386/amd-memory-encryption.rst". |
| # |
| # @amd-sev-es: The firmware supports running under AMD Secure Encrypted |
| # Virtualization - Encrypted State, as specified in the AMD64 |
| # Architecture Programmer's Manual. QEMU command line options |
| # related to this feature are documented in |
| # "docs/system/i386/amd-memory-encryption.rst". |
| # |
| # @amd-sev-snp: The firmware supports running under AMD Secure Encrypted |
| # Virtualization - Secure Nested Paging, as specified in the |
| # AMD64 Architecture Programmer's Manual. QEMU command line |
| # options related to this feature are documented in |
| # "docs/system/i386/amd-memory-encryption.rst". |
| # |
| # @intel-tdx: The firmware supports running under Intel Trust Domain |
| # Extensions (TDX). |
| # |
| # @enrolled-keys: The variable store (NVRAM) template associated with |
| # the firmware binary has the UEFI Secure Boot |
| # operational mode turned on, with certificates |
| # enrolled. |
| # |
| # @requires-smm: The firmware requires the platform to emulate SMM |
| # (System Management Mode), as defined in the AMD64 |
| # Architecture Programmer's Manual, and in the Intel(R)64 |
| # and IA-32 Architectures Software Developer's Manual. On |
| # the "pc-q35-*" machine types of the @i386 and @x86_64 |
| # emulation targets, SMM emulation can be enabled with |
| # "-machine smm=on". (On the "pc-q35-*" machine types of |
| # the @i386 emulation target, @requires-smm presents |
| # further CPU requirements; one combination known to work |
| # is "-cpu coreduo,nx=off".) If the firmware is marked as |
| # both @secure-boot and @requires-smm, then write |
| # accesses to the pflash chip (NVRAM) that holds the UEFI |
| # variable store must be restricted to code that executes |
| # in SMM, using the additional option "-global |
| # driver=cfi.pflash01,property=secure,value=on". |
| # Furthermore, a large guest-physical address space |
| # (comprising guest RAM, memory hotplug range, and 64-bit |
| # PCI MMIO aperture), and/or a high VCPU count, may |
| # present high SMRAM requirements from the firmware. On |
| # the "pc-q35-*" machine types of the @i386 and @x86_64 |
| # emulation targets, the SMRAM size may be increased |
| # above the default 16MB with the "-global |
| # mch.extended-tseg-mbytes=uint16" option. As a rule of |
| # thumb, the default 16MB size suffices for 1TB of |
| # guest-phys address space and a few tens of VCPUs; for |
| # every further TB of guest-phys address space, add 8MB |
| # of SMRAM. 48MB should suffice for 4TB of guest-phys |
| # address space and 2-3 hundred VCPUs. |
| # |
| # @secure-boot: The firmware implements the software interfaces for UEFI |
| # Secure Boot, as defined in the UEFI specification. Note |
| # that without @requires-smm, guest code running with |
| # kernel privileges can undermine the security of Secure |
| # Boot. |
| # |
| # @verbose-dynamic: When firmware log capture is enabled, the firmware |
| # logs a large amount of debug messages, which may |
| # impact boot performance. With log capture disabled, |
| # there is no boot performance impact. On the |
| # "pc-i440fx-*" and "pc-q35-*" machine types of the |
| # @i386 and @x86_64 emulation targets, firmware log |
| # capture can be enabled with the QEMU command line |
| # options "-chardev file,id=fwdebug,path=LOGFILEPATH |
| # -device isa-debugcon,iobase=0x402,chardev=fwdebug". |
| # @verbose-dynamic is mutually exclusive with |
| # @verbose-static. |
| # |
| # @verbose-static: The firmware unconditionally produces a large amount |
| # of debug messages, which may impact boot performance. |
| # This feature may typically be carried by certain UEFI |
| # firmware for the "virt-*" machine types of the @arm |
| # and @aarch64 emulation targets, where the debug |
| # messages are written to the first (always present) |
| # PL011 UART. @verbose-static is mutually exclusive |
| # with @verbose-dynamic. |

| # @Firmware: |
| # |
| # Describes a firmware (or a firmware use case) to management software. |
| # |
| # It is possible for multiple @Firmware elements to match the search |
| # criteria of management software. Applications thus need rules to pick |
| # one of the many matches, and users need the ability to override distro |
| # defaults. |
| # |
| # It is recommended to create firmware JSON files (each containing a |
| # single @Firmware root element) with a double-digit prefix, for example |
| # "50-ovmf.json", "50-seabios-256k.json", etc, so they can be sorted in |
| # predictable order. The firmware JSON files should be searched for in |
| # three directories: |
| # |
| # - /usr/share/qemu/firmware -- populated by distro-provided firmware |
| # packages (XDG_DATA_DIRS covers |
| # /usr/share by default), |
| # |
| # - /etc/qemu/firmware -- exclusively for sysadmins' local additions, |
| # |
| # - $XDG_CONFIG_HOME/qemu/firmware -- exclusively for per-user local |
| # additions (XDG_CONFIG_HOME |
| # defaults to $HOME/.config). |
| # |
| # Top-down, the list of directories goes from general to specific. |
| # |
| # Management software should build a list of files from all three |
| # locations, then sort the list by filename (i.e., last pathname |
| # component). Management software should choose the first JSON file on |
| # the sorted list that matches the search criteria. If a more specific |
| # directory has a file with same name as a less specific directory, then |
| # the file in the more specific directory takes effect. If the more |
| # specific file is zero length, it hides the less specific one. |
| # |
| # For example, if a distro ships |
| # |
| # - /usr/share/qemu/firmware/50-ovmf.json |
| # |
| # - /usr/share/qemu/firmware/50-seabios-256k.json |
| # |
| # then the sysadmin can prevent the default OVMF being used at all with |
| # |
| # $ touch /etc/qemu/firmware/50-ovmf.json |
| # |
| # The sysadmin can replace/alter the distro default OVMF with |
| # |
| # $ vim /etc/qemu/firmware/50-ovmf.json |
| # |
| # or they can provide a parallel OVMF with higher priority |
| # |
| # $ vim /etc/qemu/firmware/10-ovmf.json |
| # |
| # or they can provide a parallel OVMF with lower priority |
| # |
| # $ vim /etc/qemu/firmware/99-ovmf.json |
| # |
| # @description: Provides a human-readable description of the firmware. |
| # Management software may or may not display @description. |
| # |
| # @interface-types: Lists the types of interfaces that the firmware can |
| # expose to the guest OS. This is a non-empty, ordered |
| # list; entries near the beginning of @interface-types |
| # are considered more native to the firmware, and/or |
| # to have a higher quality implementation in the |
| # firmware, than entries near the end of |
| # @interface-types. |
| # |
| # @mapping: Describes the loading / mapping properties of the firmware. |
| # |
| # @targets: Collects the target architectures (QEMU system emulators) |
| # and their machine types that may execute the firmware. |
| # |
| # @features: Lists the features that the firmware supports, and the |
| # platform requirements it presents. |
| # |
| # @tags: A list of auxiliary strings associated with the firmware for |
| # which @description is not appropriate, due to the latter's |
| # possible exposure to the end-user. @tags serves development and |
| # debugging purposes only, and management software shall |
| # explicitly ignore it. |
