Each firmware executable installed on a host system should come with at least one JSON file that conforms to this schema. Each file informs the management applications about - the firmware's properties and one possible use case / feature set, - configuration bits that are required to run the firmware binary. In addition, define rules for management apps for picking the highest priority firmware JSON file when multiple such files match the search criteria. Cc: "Daniel P.

[Markus] =20 - Run spell-checker. [Markus] =20 - Rename @FirmwareType to @FirmwareOSInterface, to better express the concept. Update the enum constants accordingly (incl. documentation); in particular replace @slof with @openfirmware. Rename the @type field in @Firmware to @interface-type. [David, Gerd, Paolo, Thomas] =20 - Better yet, rename @interface-type to @interface-types (plural), and turn it into a list of @FirmwareOSInterface entries, to express an ordered compat list with multiple firmware<->OS interface types. [Dan, Eric, Gerd, Paolo] =20 - Drop @FirmwareArchitecture, and switch the type of @FirmwareTarget.@architecture to @SysEmuTarget (now defined in "common.json"). [Dan, Gerd, Markus] =20 - Switch elements of @FirmwareTarget.@machines from aliases ("pc", "q35", "virt") to concrete machine types, with glob patterns understood. [Dan, Gerd] =20 - Rename @secure-boot-enrolled-keys to @enrolled-keys, and drop the dependency on @secure-boot in its documentation. [Gerd] =20 - Describe the firmware JSON directories and the search rules to management apps, under the @Firmware element. Relatedly, remove the language on any concrete certificates under @enrolled-keys, as these can be customized through the overrides. Also refresh the commit message. [Dan, Gerd] =20 - Rename @pathname fields to @filename. [Markus] =20 - Don't replace "@executable.@filename" with "@executable.filename" (that is, keep the second @ sign), because removing the 2nd @ sign messes up the documentation ("filename" stops being type-set in monospace in the HTML, for example). [Markus] =20 - Rename @nvram_template to @nvram-template. [Thomas] =20 - Keep @x-check-firmware for a while longer. [Dan, Gerd, Markus, Paolo] =20 RFCv2: =20 - previous version (RFCv1) was posted at =20 - v2 is basically a rewrite from scratch, starting out with Dan's definitions from and , hopefully addressing others' feedback as well =20 RFCv1: =20 - Folks on the CC list, please try to see if the suggested schema is flexible enough to describe the virtual firmware(s) that you are familiar with.

On +# the "pc-q35-*" machine types of the @i386 and @x86_64 +# emulation targets, SMM emulation can be enabled with +# "-machine smm=3Don". (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".) 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=3Dcfi.pflash01,property=3Dsecure,value=3Don". +# 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.

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.

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.
