I think we should probably add a couple of lines in the meson.build on the amber branch, like this: if gallium_drivers.count() != 0 or vulkan_drivers.count() != 0 error("You shouldn't package Gallium or Vulkan drivers from the amber branch; please only enable these in the standard Mesa package build.") endif Do you think that would be enough to resolve the distro packages maintainers' confusion? Hi, I think the problem with Amber is that the situation isn't clear. Branch appeared from nowhere and without clear goal. (Some commits for new drivers landed on it. So it may be giving wrong idea about LTS.) Moving into separate repo was my first idea to address this problem, but I agree it may not be best solution. Overall I think we have problems: - branch is difficult to find (adding link in readme of main branch and renaming branch?) - sometimes commits for drivers still supported by main branch are modifying gallium, so there's chance of regression (or accidental use). (we can disable them, but probably removing is better?) - people don't correlate amber and legacy. Here's video with with chipset 945g (915g) and lubuntu. https://youtu.be/nCjantxylV4?t=1160 (btw there's another problem why 945g only advertise gl 1.4) So adding "Legacy" or "Legacy driver" after word Mesa my be a good idea.

Re: Moving amber into separate repo?
Currently, amber branch only have * radeon * r200 * i915 * i965 * nouveau (the DRI driver for NV04-NV20) Indeed, I think i915 and i965 can also be removed from amber branch, because they have alternative i915g/ crocus alternatives in main branch, maybe in future, after all code that's not belongs to amber removed, we can even place amber under main branch's src/amber folder? -- 此致 礼 罗勇刚 Yours sincerely, Yonggang Luo

If the fd.o admins are complaining about disk usage, we can take steps to reduce that but it's entirely irrelevant to the discussion of whether amber should get it's own repo. Pulling amber into a separate repo won't reduce disk usage. If anything, it'll slightly increase it but not by an amount that's likely to matter. Let's stay focused on actual reasons that might matter, like user confusion (if that's actually happening). --Jason

Re: Moving amber into separate repo?
Removing mainline drivers from the build system of Amber is a good idea.

Re: Moving amber into separate repo?
Git stores all commits. Removing files at the top of main doesn't make the repository smaller. It actually makes it bigger. Forking the repository would also double the size on the server.

Moving amber into separate repo?
Hi, recently I've seen case of user been using Amber when hardware was supported by mainline mesa. This gave me a couple of thoughts. 1) Users don't correlate "Amber" with "Legacy" and probably it's gonna be best to always also print "Legacy" together with "Mesa". 2) Not sure if problem of choosing best driver is on mesa's or distro maintainer's side, but it became more complicated for maintainers. I'm thinking that moving Amber into separate repo may make this situation more clear. (Disabling duplicated drivers or only allowing glsl_to_tgsi codepath may futher help.) Some more reasoning from gitlab: * web based tools provided by gitlab are quite useful, unfortunately they work best with main branch. * repo is growing large. Amber kinda requires long history, modern mesa not. This may be good spot to split if cleanup is required. * imho having amber's issues in this repo, won't create new contributors. Due to lack of kernel driver (on commercial level) or documentation for these gpus, so you need to be both mesa and kernel developer. (Any contribution is gonna require deep knowledge about hardware, domain and time consuming effort.) * for normal users (not software developers) amber is kinda "hidden under the carpet". Communities like vogons may be interested in having simpler access to kinda documentation for these ancient gpus. Thanks for all insights, Filip.
