d17c5b770972854a4fe4cf5cc22e17eb21cdc787 - perf build: install-build-deps: add RHEL family devel package mapping

Tue, 11 Aug 2026 20:29:00 +0200

perf build: install-build-deps: add RHEL family devel package mappingWith the Fedora mapping in place, this patch extends it to the RHELfamily (RHEL, CentOS Stream, Rocky Linux, AlmaLinux, Oracle Linux),which shares most Fedora package names and runs dnf (RHEL 8 andlater). The names that differ are handled by probing the enabledrepos: - zlib.h comes from zlib-ng-compat-devel on the RHEL 10 family, zlib-devel on RHEL 9 and earlier; - there is no java-latest-openjdk-devel: the JDK devel package is versioned per release, java-21-openjdk-devel on the RHEL 10 family, java-17-openjdk-devel on RHEL 9, java-11-openjdk-devel on RHEL 8; - libbpf-devel and capstone-devel live in the CRB repo on RHEL and CentOS Stream 10, in EPEL on RHEL 9 and earlier; - libbabeltrace2-devel is not packaged on the RHEL 10 family.Packages not available on the enabled repos are skipped instead ofaborting the dnf transaction, and are listed at the end of the run, withthe repo that provides them pointed out in the header comment and helptext: a distro with CRB/EPEL enabled gets the full set, one without themstill installs what it can.This also holds for the base set: e.g. 'rust' exists only as therust-toolset AppStream module on RHEL 8 and 9, where it is notinstallable as a plain package, so it is skipped and noted there insteadof failing the whole dnf transaction.The base set lists pkgconf-pkg-config instead of pkgconfig: bothfamilies have been on pkgconf since Fedora 26 / RHEL 8, where'pkgconfig' lives only as a virtual Provides of that subpackage, anda minimal RHEL-family container may not have it preinstalled.Validated on a fresh CentOS Stream 10 distrobox container, with theCRB repo enabled, so the host system is not modified: distrobox create --image quay.io/centos/centos:stream10 distrobox enter centos-stream10 dnf config-manager --set-enabled crb make -C tools/perf install-build-depswhich installed the 28 available mapped packages; libbabeltrace2-devel, theonly mapped package with no RHEL 10 package, is reported at the endof the run.A subsequent 'make -C tools/perf feature-dump' enabled every featurewith an external dependency the RHEL 10 family provides, includinglibbpf and libcapstone from the CRB repo, with onlybabeltrace2-ctf-writer left out along with the deliberately unmappedopt-in features.Re-running the target is a no-op (dnf reports "Nothing to do"); with theCRB repo disabled, the skipped packages are instead listed in theend-of-run note, whose header comment and help text point out which repoprovides them.Members of the family without dnf (RHEL 7 and earlier, e.g. OracleLinux 7, a yum-only distro) are rejected with an explicit error whilethe dnf-based members get the full mapping.Example of its --list: $ grep PRETTY_NAME /etc/os-release PRETTY_NAME="Fedora Linux 44 (Toolbx Container Image)" $ tools/perf/scripts/install-build-deps.sh --list --distro rhel bison capstone-devel clang-devel elfutils-debuginfod-client-devel elfutils-devel elfutils-libelf-devel flex gcc gcc-c++ glibc-devel java-latest-openjdk-devel kernel-headers libbabeltrace2-devel libbpf-devel libpfm-devel libstdc++-devel libtraceevent-devel libzstd-devel llvm-devel make numactl-devel openssl-devel pkgconf-pkg-config python3-devel python3-setuptools rust slang-devel systemtap-sdt-devel xz-devel zlib-ng-compat-devel $Assisted-by: opencode:deepseek-v4-flash-freeAssisted-by: claude:claude-opus-4-7Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Namhyung Kim List of files: /linux/tools/perf/scripts/install-build-deps.sh

Tue, 11 Aug 2026 20:28:58 +0200

perf build: install-build-deps: add Debian devel package mappingWith the Fedora and Ubuntu mappings in place, this patch adds Debiansupport: Debian installs the same devel packages, under the samenames, as the Ubuntu mapping, so it reuses debian_pkg_for() anddebian_base_pkgs as-is, with only auto-detection in detect_distro()(and the shared apt-get install path) added, keeping the script'sper-distro dispatch ready for distros with their own package names.Validated on a fresh Debian 13 (trixie) container so the host systemis not modified: distrobox create --image debian:trixie distrobox enter debian-trixie make -C tools/perf install-build-depswhich installed the 29 mapped packages; re-running the target is ano-op (apt-get reports "0 newly installed"). A subsequent clean buildenabled the same feature set as Ubuntu: 'perf version --build-options'shows every feature with an external dependency Debian has a packagefor [on], including the BPF skeletons compiled with clang/llvm(libLLVM), the python binding and the C++-based features, with onlythe deliberately unmapped libbfd family, libperl, libunwind and theCoreSight (libopencsd) packages [OFF].RHEL, whose package mapping is largely similar to Fedora's, is theremaining planned distro, to be enabled once that mapping isvalidated on it.Example of its --list: $ grep PRETTY_NAME /etc/os-release PRETTY_NAME="Fedora Linux 44 (Toolbx Container Image)" $ tools/perf/scripts/install-build-deps.sh --list --distro debian bison clang default-jdk flex g++ gcc libbabeltrace2-dev libbpf-dev libc6-dev libcapstone-dev libdebuginfod-dev libdw-dev libelf-dev liblzma-dev libnuma-dev libpfm4-dev libslang2-dev libssl-dev libtraceevent-dev libzstd-dev linux-libc-dev llvm-dev make pkg-config python3-dev python3-setuptools rustc systemtap-sdt-dev zlib1g-dev $Assisted-by: opencode:deepseek-v4-flash-freeSigned-off-by: Arnaldo Carvalho de Melo Signed-off-by: Namhyung Kim List of files: /linux/tools/perf/scripts/install-build-deps.sh

Tue, 11 Aug 2026 20:28:57 +0200

perf build: install-build-deps: add Ubuntu devel package mappingWith the framework and Fedora mapping in place, this patch adds theUbuntu (apt) mapping: same feature-to-package correspondence as theFedora one, adapted to Debian packaging conventions (libfoo-dev), ona per-distro dispatch so future distros can pick their own mapping orreuse one of these (Debian shares the Ubuntu mapping).Notable differences from Fedora: - base set: g++ (ships libstdc++-*-dev, covering cxa-demangle), pkg-config (installed implicitly by Fedora's default toolchain metapackage, but not by Ubuntu's), linux-libc-dev and libc6-dev instead of kernel-headers and glibc-devel, and rustc for rust; - cxa-demangle maps to nothing, covered by g++'s libstdc++; - the clang-bpf-co-re test needs the clang compiler binary (Fedora's clang-devel provides it transitively), and llvm-dev, which also brings llvm-config (deps on the llvm package), used by the llvm/llvm-perf tests; - libslang maps to libslang2-dev and jvmti to default-jdk; - the install command runs 'apt-get update' first since a fresh container has no package indexes, unlike dnf.Validated on a fresh Ubuntu 26.04 distrobox container so the hostsystem is not modified: distrobox create --image ubuntu:26.04 distrobox enter ubuntu-26-04 make -C tools/perf install-build-depswhich installed the 29 mapped packages; a subsequent clean O= buildenabled every feature with an external dependency Ubuntu has apackage for: perf's build-options then showed all of them [on],including the BPF skeletons requiring clang/llvm, the python bindingand the C++-based features, with only the deliberately unmapped(deprecated) libbfd family, libperl and libunwind [OFF], and thebuild linked libpfm, libbabeltrace2-ctf-writer, libcapstone,libtraceevent, libslang, libnuma, libdw and libssl. Re-running thetarget is a no-op (apt-get reports "0 newly installed").Debian (trixie) is the next planned distro: it shares this Ubuntumapping, so enabling it reuses it as-is, once it gets validated on aDebian release.Example of its --list: $ grep PRETTY_NAME /etc/os-release PRETTY_NAME="Fedora Linux 44 (Toolbx Container Image)" $ tools/perf/scripts/install-build-deps.sh --list --distro ubuntu bison clang default-jdk flex g++ gcc libbabeltrace2-dev libbpf-dev libc6-dev libcapstone-dev libdebuginfod-dev libdw-dev libelf-dev liblzma-dev libnuma-dev libpfm4-dev libslang2-dev libssl-dev libtraceevent-dev libzstd-dev linux-libc-dev llvm-dev make pkg-config python3-dev python3-setuptools rustc systemtap-sdt-dev zlib1g-dev $Assisted-by: opencode:deepseek-v4-flash-freeSigned-off-by: Arnaldo Carvalho de Melo Signed-off-by: Namhyung Kim List of files: /linux/tools/perf/scripts/install-build-deps.sh

bc3fdd6adb9903b1f1fd85cd9532c7bfc961dcbc - perf build: Add install-build-deps framework to install devel packages

Tue, 11 Aug 2026 20:28:55 +0200

perf build: Add install-build-deps framework to install devel packagesInstalling the development packages needed to build perf iserror-prone on a fresh distro install: the packages are scatteredacross the feature tests in tools/build/feature/, each checking for aspecific header/library, and the build only tells you what's missingafter failing a check.This series adds a 'make -C tools/perf install-build-deps' target toinstall them in one go, deriving the package list from the feature teststhemselves.This commit adds the framework, on top of the parse-time compilerprobe guard from the previous commit:- the install-build-deps target in tools/perf/Makefile.perf, exempted from the config/feature detection pass, since it must run in a fresh container, before gcc or pkg-config exist, to install them;- the install-build-deps.sh script, with --list, --dry-run and --distro options, distro detection (Fedora and Ubuntu), dnf and apt-get drivers, root/passwordless-sudo handling, and the base packages common to any build: compiler, C++ compiler, make, flex, bison, libc and kernel headers, python3-setuptools (needed by the python binding) and rust (checked by the rust feature test);- the parse-time probes for optional tools, like pkg-config, use 'command -v' with stderr discarded, so a fresh container without them gets no 'which: no pkg-config in (...)' spew from make;- the script does not rely on 'set -e': its error paths are explicit, since the make target runs it via $(SHELL), where a shebang option would be ignored anyway, so direct and make-driven runs behave the same.The per-feature mappings, from each feature test to the devel packageproviding its headers on a given distro, are added by the follow-uppatches, one per distro, together with the validation of each mappingin a fresh container: until then the target installs just the basetoolchain.Assisted-by: opencode:deepseek-v4-flash-freeSigned-off-by: Arnaldo Carvalho de Melo Signed-off-by: Namhyung Kim List of files: /linux/tools/perf/scripts/install-build-deps.sh
