Hi Tony, I'm generally all for using branches, we use them extensively internally. IMO, the options we have in gerrit for what both of us are trying to accomplish, us with SVE and you with the GPU, are as follows:
1. We create different repositories per user / institution and push between repos. 2. We create branch "namespaces" in the main repo (e.g., arm/**, amd/**, users/a.hacker/**) Gerrit is able to handle permissions and policies (e.g., whether some users can push without review and who is allowed to review) per branch as well as per repo. There are some differences in what you can do and how you do it, but in general, they are roughly equivalent when it comes to permissions. We obviously already went with option one. The main benefit, as I see it, of this option is that we don't pollute the branch namespace with pre-release changes. I would argue that this option scales a bit better in terms of usability as well. Once you start having a lot of working branches, cloning the repo will be pretty annoying. The Linux uses a similar strategy and most well-known kernel devs have their own repos on git.kernel.org and Linus curates the master repo.

Hi All, I have a question about using branches in the mainline gem5 repo. I see ARM have a separate repo here: https://gem5-review.googlesource.com/admin/projects/arm/gem5. It is used for staging ARM features under development. At AMD we would like to do something similar, as we have some significant changes to the GPU model we would like to push out to the public. We were thinking about doing so with branches, and were wondering what others thought about branches? I'm sure it's been discussed somewhat in the past, but I can't find much searching through old posts. What I was thinking would be to have institutional branches, like AMD or ARM branches, and perhaps users from those institutions who are also gem5 maintainers could have user specific branches. We use branches a lot internally and find them extremely useful. So I'd like to get a better idea why there is an aversion to using branches on the public tree, if there is such an aversion. -Tony _______________________________________________ gem5-dev mailing list [email protected] http://m5sim.org/mailman/listinfo/gem5-dev
