yum packaging nvidia plugin

Overview

Packaging templates for yum and dnf based Linux distros for Python plugin to manage NVIDIA driver precompiled kernel module packages.

The main branch contains this README and a sample build script. The .spec and nvidia.py files can be found in the appropriate rhel7, rhel8, and fedora branches.

Deliverables

This repo contains the .spec file used to build the following RPM packages:

• RHEL8 or Fedora

  dnf-plugin-nvidia-${version}-${rel}.${dist}.noarch.rpm
  > ex: dnf-plugin-nvidia-2.0-1.el8.noarch.rpm

• RHEL7

  yum-plugin-nvidia-${version}-${rel}.${dist}.noarch.rpm
  > ex: yum-plugin-nvidia-0.5-1.el7.noarch.rpm

Prerequisites

Clone this git repository:

Supported branches: rhel7, rhel8 & fedora

git clone -b ${branch} https://github.com/NVIDIA/yum-packaging-nvidia-plugin
> ex: git clone -b rhel8 https://github.com/NVIDIA/yum-packaging-nvidia-plugin

Install build dependencies

note: these are only needed for building not installation

# Python
yum install python36

# Packaging
yum install rpm-build

Demo

Building with script

Fetch script from main branch

cd yum-packaging-nvidia-plugin
git checkout remotes/origin/main -- build.sh

Usage

./build.sh

Building Manually

Packaging plugin

RHEL8 or Fedora

mkdir BUILD BUILDROOT RPMS SRPMS SOURCES SPECS
cp nvidia-dnf.py SOURCES/
cp dnf-plugin-nvidia.spec SPECS/

rpmbuild \
    --define "%_topdir $(pwd)" \
    --define "debug_package %{nil}" \
    --define "_python_sitelib $pythonLocation" \
    -v -bb SPECS/dnf-plugin-nvidia.spec

> ex: rpmbuild \
    --define "%_topdir $(pwd)" \
    --define "debug_package %{nil}" \
    --define "_python_sitelib /usr/lib/python3.6/site-packages" \
    -v -bb SPECS/dnf-plugin-nvidia.spec

RHEL7

mkdir BUILD BUILDROOT RPMS SRPMS SOURCES SPECS
cp nvidia.conf SOURCES/
cp nvidia-yum.py SOURCES/
cp yum-plugin-nvidia.spec SPECS/

rpmbuild \
    --define "%_topdir $(pwd)" \
    --define "debug_package %{nil}" \
    -v -bb SPECS/yum-plugin-nvidia.spec

Sign RPM package(s) with GPG signing key

If one does not already exist, generate a GPG key pair

gpg --generate-key

Set $gpgKey to secret key ID.

gpgArgs="/usr/bin/gpg --force-v3-sigs --digest-algo=sha512 --no-verbose --no-armor --no-secmem-warning"
for package in RPMS/noarch/*-plugin-nvidia*.rpm; do
  rpm \
    --define "%_signature gpg" \
    --define "%_gpg_name $gpgKey" \
    --define "%__gpg /usr/bin/gpg" \
    --define "%_gpg_digest_algo sha512" \
    --define "%_binary_filedigest_algorithm 10" \
    --define "%__gpg_sign_cmd %{__gpg} $gpgArgs -u %{_gpg_name} \
      -sbo %{__signature_filename} %{__plaintext_filename}" \
    --addsign "$package";
done

Blocking kernel updates

• RHEL8 or Fedora
  Kernel updates will be blocked in the absence of the availability of a compatible kmod package for that kernel and driver combination.

  The kernel and kernel-core packages will be removed from such dnf transactions and an error message will be printed, ex:

  NOTE: Skipping kernel installation since no kernel module package kmod-nvidia-450.51.06-4.18.0-193.19.1 for kernel 4.18.0-193.19.1 and NVIDIA driver 450.51.06-1.el8.x86_64 could be found

Debugging

• RHEL8 or Fedora
  Heuristic information can be printed via CLI, such as installed kernel, installed kmod packages, available kernels, available drivers, and available kmod packages.

  dnf nvidia-plugin
