qsdk 12.1的内核版本是5.4。这里的工作是主要是参考qsdk的改动，移植到5.15内核。5.15内核是longterm内核版本。
首先我们下载linux仓库，方便做对比。使用codeaurora北京的linux镜像。
$ git remote -v
origin git://kernel.source.codeaurora.cn/pub/scm/linux/kernel/git/torvalds/linux.git (fetch)
origin git://kernel.source.codeaurora.cn/pub/scm/linux/kernel/git/torvalds/linux.git (push)
stable git://kernel.source.codeaurora.cn/pub/scm/linux/kernel/git/stable/linux.git (fetch)
stable git://kernel.source.codeaurora.cn/pub/scm/linux/kernel/git/stable/linux.git (push)
$ git branch -vv
* linux-5.4.y 01565c91b789 [stable/linux-5.4.y] Linux 5.4.193
master 4634129ad9fd [origin/master] Merge tag 'soc-fixes-5.16-4' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
查看qsdk 12.1的manifests。
<project name="clo/qsdk/oss/kernel/linux-ipq-5.4" path="qsdk/qca/src/linux-5.4" revision="c2f73a5387280d0fa225223ea517e6620d35f7e7" upstream="NHSS.QSDK.12.1.r3"/>
确定其分支是 NHSS.QSDK.12.1.r3，commit 是 c2f73a53.
然后下载quic维护的5.4内核仓库
$ git remote -v
origin https://git.codelinaro.org/clo/qsdk/oss/kernel/linux-ipq-5.4.git (fetch)
origin https://git.codelinaro.org/clo/qsdk/oss/kernel/linux-ipq-5.4.git (push)
$ git branch -vv
* NHSS.QSDK.12.1.r3 c2f73a5387280 [origin/NHSS.QSDK.12.1.r3] dts: ipq9574: Add IPQ9754 and QCN9224 Wifi nodes for AL02-C6
clo/main 4426e6017f73b [origin/clo/main] Linux 5.4.191
可以看到12.1.r3分支的HEAD就是c2f7。
linux官方的5.4.y分支的HEAD是5.4.193 tag。
查看 NHSS.QSDK.12.1.r3的git log发现它最近的tag是
e3c95128def1c (tag: v5.4.164) Linux 5.4.164
查看linux的5.4.164 tag
e3c95128def1 (tag: v5.4.164) Linux 5.4.164
他们的commit相同。也就是说，quic的所有提交都rebase到了5.4.164. 这样做应该也是为了更好的merge新的5.4.x版本。
这样就很好办了。直接在linux-ipq-5.4比较head和v5.4.164就可以了。
首先查看改动的文件
$ git diff --name-only v5.4.164 HEAD
有1300多个改动的文件，涉及Documentation, arch/arm, arch/arm64, arch/mips, block, drivers, fs, include, init, ipc, kernel, lib, mm, net, samples, scripts, security, sound, tools, usr, virt, Makfile.等目录的改动。找出涉及IPQ5018的改动，合入。
使用git log查看从tag到head一个文件或目录的改动，比如主Makefile.有改动
$ git log -p --stat --full-diff v5.4.164...HEAD Makefile
主要是arch/arm arch/amr64涉及的改动。
