* How to track the source tree of kernel @ 2022-05-18 14:47 chen.mingzheng 2022-05-18 15:17 ` Greg KH 0 siblings, 1 reply; 4+ messages in thread From: chen.mingzheng @ 2022-05-18 14:47 UTC (permalink / raw) To: kernelnewbies Hi Guys, Sorry to bother you all. I'm just starting learning linux with a rpi4b. I found the raspi source tree have many branches, which are different from the kernel source tree, which also have many branches. I want to know how should I track the source code. should I track all branches from the remote repo, or just stick to a specific branch? How did you do so that you can catch up to lastest kernel? Thanks in advance! Sincerely, A Linux newbies. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies ^ permalink raw reply [flat|nested] 4+ messages in thread

So, what exactly do you want to do? thanks, greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies ^ permalink raw reply [flat|nested] 4+ messages in thread

I' m not quite familiar with the email rules, I will pay attention to it. What I'm trying to do is to become a kernel developer, especially a driver developer. Maybe this is a more general object and lacks of clear steps. So I want to learn about the work flow ofkernel development to decompose the object. And, I think, maybe the first step is to catch up with a branch of kernel source, for which I setup a raspi to track the kernel source daily with the help of crontab, and compile the kernel when there is a new commit and send an email to get a notification. Next, I should develop on the specific branch, and learn how to submit a patch to kernel. But now, I'm confused that there so many branches in linux kernel source and other linux distribution source such as raspberrypi/linux.git, and I only know about how to submit a patch to kernel from kernel documents or kernelnewbies or other websites. Can I just work on a specific platform and submit a patch to kernel? I currently work on i.mx6 platform and have a raspi4b for learning. Based on the linux SDK from board supplier, l developed some camera drivers. The SDK contains a dirty 4.1.15 kernel source, a uboot, anda prebuild rootfs archive. and the SDK is not controlled by a git, it's just an archive. Supposed now, I know how to submit a patch to which branch, is therep any tests need to be run before I submit? or is there a requirement for writing a test program to test my driver first? Could you give me some advices on what should I do next, or is l going toward a wrong direction? Thanks in advance, chen. ________________________________ 发件人: Greg KH <greg@kroah.com> 发送时间: 2022年5月18日星期三 23:17 收件人: chen.mingzheng <chen.mingzheng@outlook.com> 抄送: kernelnewbies@kernelnewbies.org <kernelnewbies@kernelnewbies.org> 主题: Re: How to track the source tree of kernel On Wed, May 18, 2022 at 10:47:59PM +0800, chen.mingzheng wrote: > Hi Guys, > > Sorry to bother you all.
