<p>The RESF primary purpose is to rebuild and debrand a 1:1 bug replica of RHEL and have built tools that support this process. The SIGs are modifications to that initial purpose while reusing the tooling already developed for the base dist-git process. The SIG dist-gits are controlled by automation that executes the <code>srpmproc</code> command so to modify the dist-git in any manner a developer needs to integrate their changes to the <code>sig/cloud/patch</code> configs related to that SIG. <a href="https://git.rockylinux.org/sig/cloud/kernel">SIG/CLOUD - SRPMPROC Kernel Patches</a> -&gt; <a href="https://git.rockylinux.org/sig/cloud/rpms/kernel">SIG/CLOUD - Kernel dist-git</a>
<code>srpmproc</code> is designed to only modify the <code>dist-git</code> and if a SIG wants a particular driver branch, that cleanly applies, they need to use another program called <code>sideline</code> to create a monolithic patch against a point in time source code base. That is then added to the <code>SIDELINE/_supporting</code> directory of the <code>sig/cloud/patch/kernel</code> directory. <code>srpmproc</code> knows that these patches are to be included into <code>SOURCES/</code> and added to <code>applypatch</code> directives in the <code>kernel.spec</code> with appropriate config settings for <code>srpmproc</code>.</p>

<p>The general process by the RESF was not initially created with ad-hoc development in mind but rather pulling entire branches from upstream into the current RESF base releases. The following is to provide a general guide on how to develop with <code>srpmproc</code> as the <code>SIG/CLOUD</code> dist-git is not to be modified directly for development support. </p>
<p>Basic Process:</p>
<ol>
<li>Clone <code>sig/cloud/patch/kernel</code> repo</li>
<li>Run Local <code>srpmproc</code></li>
<li>Build local git repo for kernel source</li>
<li>Make Changes, local builds and testing (not covered in doc)</li>
<li>Source changes from local build to <code>sig/cloud/patch/kernel</code></li>
<li>Regenerate <code>dist-git</code> with srpmproc</li>
<li>Mock test rpm builds.</li>
</ol>
<p>The following sections are going to be based off real work that was ultimately abandoned for Rocky8.</p>
<h3 id="prep-for-srpmproc-cloning-patchkernel">Prep for SRPMPROC: Cloning patch/kernel<a class="headerlink" href="#prep-for-srpmproc-cloning-patchkernel" title="Permanent link">&para;</a></h3>
<p>This is the general prep of the directories used. Note some directions for <code>srpmproc</code> use a temp directory, that is not used here as depending on how long development can last you could lose important work, specifically around the <code>srpmproc-cache</code></p>
<p>Create Needed Directories
<div class="highlight"><pre><span></span><code>mkdir -p SIG/cloud/
cd SIG/cloud/
mkdir -p {rpms,patch,src,srpmproc-cache,src-git}
</code></pre></div></p>
<p>Clone the configuration Directives and Patches repo
<div class="highlight"><pre><span></span><code>git clone ssh://git@git.rockylinux.org:22220/sig/cloud/patch/kernel.git patch/kernel.git
</code></pre></div></p>
<p>Script example used to manage running <code>srpmproc</code> during
<div class="highlight"><pre><span></span><code>#!/bin/bash
set -x
MYHOME=`pwd`
~/bin/srpmproc --cdn rocky8 --version 8 \
--upstream-prefix &quot;file://${MYHOME}/&quot; \

</code></pre></div></p>
<h3 id="srpmproc-1st-run"><code>srpmproc</code> 1st run<a class="headerlink" href="#srpmproc-1st-run" title="Permanent link">&para;</a></h3>
<p>This step will be missing a lot of output just so that we can focus on the results and where we source building a local source git tree.</p>
<p>RUN SRPMPROC with script or by hand.
<div class="highlight"><pre><span></span><code>./sprmproc.sh
</code></pre></div></p>
<p>After <code>srpmproc</code> runs you'll have a a new directory (<code>kernel</code>) in your current path that will have a working copy of the <code>sig/cloud</code> <code>dist-git</code> used to build the RPMs for <code>sig/cloud</code> </p>
<p>Example:
<div class="highlight"><pre><span></span><code>$ ls -a kernel/r8/
. .. .gitignore .kernel.checksum .kernel.metadata SOURCES SPECS
</code></pre></div></p>
<h3 id="build-local-git-tree-repo">Build Local git tree repo<a class="headerlink" href="#build-local-git-tree-repo" title="Permanent link">&para;</a></h3>
<p>At this point the dist-git can extracted and modified for change however the individual wants.
Below is how the author did this.</p>
<p>Extract the TarBall note this was the original 8.9 change and the exact version has incremented.
<div class="highlight"><pre><span></span><code>tar xvf kernel/r8/SOURCES/linux-4.18.0-513.9.1.el8_9.tar.xz -C src-git/

<p>This is ultimately up to the back porter but due to the massive monolithic patch that is preferred by <code>srpmproc</code> and its current configuration changes its best to leave some markers in the backport commits.

clocksource/arm_arch_timer: Add build-time guards for unhandled register accesses
jira ROC-2809
commit 4775bc63f880001ee4fbd6456b12ab04674149e3
As we are about to change the registers that are used by the driver,
start by adding build-time checks to ensure that we always handle
all registers and access modes.

<p>Compile the kernel in place (outside the scope of this document).
You could also export all these patches and manually add them to the <code>dist-git</code> like by many other <code>dist-git</code> builds however they can not be submitted to the SIG from this state. So this would be exclusively for your local testing. If you choose to do this and are not sure how to use <code>mock</code> builds, <a href="https://skip.linuxdn.org/blog.html#005_Rocky5_BuildLab_Part1">Skip's Blog</a> as a relevant primer tutorial for Rocky</p>

<p>This requires manual modification of directives file as <code>srpmproc</code> needs to be told what to do with the new file.</p>
<p>Some unique notes about <code>srpmproc</code>
* <code>patch</code> - directive applies a patch to the <code>dist-git</code> files themselves, NOT adding a patch the <code>.spec</code> file
* <code>add: {file: &lt;path&gt;}</code> is what will copy the file from <code>srpmproc</code> directories INTO the <code>dist-git</code> <code>SOURCES/</code> location.
* <code>spec_change</code> is where we configure changes to the specfile like would be done to a standard <code>dist-git</code>
* This is processed in order, so <code>search_and_replace</code> will be processed in order for adding patches. Make sure the patches are applied in correct order.
* Since the file is processed in order the changelog items need to be placed in reverse order ie newest item at the top.</p>
<p>Example of a modification, NOTE <code>search_and_replace</code> were below the <code>chagnelog</code> entries. They were moved on this abandoned work such that the <code>file</code> and <code>search_and_replace</code> were located generally in order relation to how they would be modified in a pure <code>dist-git</code> style repo. In a hope to avoid jumping back and forth in the file.

<p>As of 2024.01.29 <code>srpmproc</code> cannot work off dev branches so this code will need to be on the main <code>r&lt;version&gt;</code> branch. Once this is done re-running <code>srpmproc</code> using the above script or exact same command parameters used when creating the local <code>srpmproc</code> will use the new local HEAD.</p>

Add AmpereOne CPU clocksource patches to r8
There is a request in the cloud to support fixes for AmpereOne CPUs with
clocksource fixes in the Rocky8 kernels. This was a large manual
backport with cherry-picks and picking up all known bugfixes for pulled
patches.
