It includes kernel-resident ACPI components and user-space utilities such as iASL, acpidump, acpiexec, acpixtract, and related tools. ### Project history Intel's official ACPICA overview describes ACPICA as a reference implementation of the Advanced Configuration and Power Interface specification, written in ANSI C for portability across 32-bit and 64-bit operating-system environments. The same overview says ACPICA contains both kernel-mode and user-mode components. The official download page says ACPICA is maintained in Git, with commits made as individual fixes and features are completed, and provides source packages, makefiles, utilities, and release logs. The GitHub repository was created in 2011 and mirrors the source tree with documents, source, tests, and release tags. ### Adoption history ACPICA has an unusually direct path from upstream package to operating-system internals. Intel's overview says ACPICA updates for Linux are provided periodically in patch form and that the code is converted and integrated into the Linux kernel source. The input package-manager facts show the user-space tools packaged across Homebrew, Alpine, Chocolatey, DNF, MacPorts, Arch, and openSUSE. ### How it is used Package users most often encounter ACPICA through command-line utilities: iASL compiles and disassembles ACPI Source Language and AML, acpidump obtains ACPI tables, acpixtract extracts tables, and acpiexec helps exercise AML execution. The GitHub source tree's compiler help documents iASL options for compiling, disassembling, generating listings, and creating table templates. ### Why package nerds care ACPICA matters to package nerds because it sits at the boundary between firmware specifications, kernel enablement, and user-space diagnostics. Packaging it gives developers and distro maintainers reproducible tools for inspecting, compiling, and debugging ACPI tables without depending on a full kernel tree. ### Timeline - 2011-08-08: GitHub repository created. - 2015-06-16: GitHub tag R061615 appears in the repository tag list. - 2021: Intel overview references ACPICA version 20210331 in documentation text. - 2024-12-12: ACPICA release R2024_12_12 published on GitHub. - 2026-04-08: ACPICA Release version 20260408 published. ### Related projects - Related projects include the ACPI specification, Linux ACPI subsystem work, firmware/BIOS development workflows, iASL, acpidump, acpiexec, and ACPI table debugging tools. ### Sources - Intel overview, download and documentation pages, GitHub repository/release metadata, and source_facts.package-manager. ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** acpica - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - apk - acpica - 20250807-r0: normalized package name match | Alpine Linux edge package indexes: acpica from https://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/APKINDEX.tar.gz | ACPI Component Architecture utilities | https://www.acpica.org - apk - iasl - 20250807-r0: normalized package name match | Alpine Linux edge package indexes: iasl from https://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/APKINDEX.tar.gz | ACPI ASL compiler | https://www.acpica.org - pacman - acpica - 20251212-1: normalized package name match | Arch Linux sync databases: acpica from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | ACPI tools, including Intel ACPI Source Language compiler | https://acpica.org - zypper - acpica - 20260408-2.2: normalized package name match | openSUSE Tumbleweed package metadata: acpica from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | A set of tools to display and debug BIOS ACPI tables | https://acpica.org - MacPorts - acpica: normalized package name match | MacPorts ports tree: devel/acpica/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 - dnf - acpica-tools - 20260408-1.fc45: installed executable or alias match | Fedora Rawhide package metadata: acpica-tools from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | ACPICA tools for the development and debug of ACPI tables | https://www.intel.com/content/www/us/en/developer/topic-technology/open/acpica/overview.html - Chocolatey - iasl: installed executable or alias match | Chocolatey community package catalog: iasl from http://community.chocolatey.org/api/v2/Packages?$filter=IsLatestVersion&$select=Id&$top=1000&$skiptoken='11','hexchat' ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [b43-fwcutter](https://www.automicvault.com/pkg/brew/b43-fwcutter/) - Shares av.db curated category or tags: cli, firmware, system. - [dfu-programmer](https://www.automicvault.com/pkg/brew/dfu-programmer/) - Shares av.db curated category or tags: cli, firmware, system. - [dfu-util](https://www.automicvault.com/pkg/brew/dfu-util/) - Shares av.db curated category or tags: cli, firmware, system. - [flashrom](https://www.automicvault.com/pkg/brew/flashrom/) - Shares av.db curated category or tags: cli, firmware, system. - [fon-flash-cli](https://www.automicvault.com/pkg/brew/fon-flash-cli/) - Shares av.db curated category or tags: cli, firmware, system. - [fwup](https://www.automicvault.com/pkg/brew/fwup/) - Shares av.db curated category or tags: cli, firmware, system. - [dpcmd](https://www.automicvault.com/pkg/brew/dpcmd/) - Shares av.db curated category or tags: cli, firmware, system. - [fwupd](https://www.automicvault.com/pkg/brew/fwupd/) - Shares av.db curated category or tags: cli, firmware, system. ## Combined YAML source View the package source record on GitHub.
