Jackson noted, "Following up from the classic swrast OSMesa removal in favor of llvmpipe/softpipe, remove the classic swrast DRI driver. It's unused by any distribution -- debian was the last holdout until this week, which had it enabled instead of softpipe on obscure platforms (non-LLVM and hurd). Now that debian has switched, remove the driver so nobody can accidentally enable it again."
Hmm, so if I understand correctly, if a target doesn't have an LLVM backend at the moment, we can still use softpipe, can't we? I'll need to talk with upstream about that. Adrian

I would assume that Stefan Dirsch is already working on Mesa 21. I'd welcome it because the current Mesa in Tumbleweed looks like it would need quite a number of patches for LLVM 12. (I haven't even tried, I'm running 21.0.1 with two patches right now.) Best regards, Aaron

Tried once. Gave up after 2 hours fiddling around with meson options, when other things popped up with higher severity and priority. Can't say for sure, but I expect this to be a task for several days to get the update done. :-(

Interesting. Is this on openSUSE with our Mesa package and your changes/patches on top of it? Or did you build Mesa 21 manually? Anyway, help with the Mesa update to version 21 would be appreciated. ;-) Thanks, Stefan Public Key available ------------------------------------------------------ Stefan Dirsch (Res. & Dev.)

I have an unstable Mesa git snapshot package in my home project which is base on X11:XOrg (concenering the packaging), it may help with the initial update. Lets see if i find the time to push a first version of Mesa 21.0 to X11:XOrg this weekend.

One problem is that swrast is gone and you've used that as "alibi" driver in the Mesa package (the actual drivers are all built in Mesa-drivers). I've replaced it with nouveau, but maybe there is a better option. A bigger problem is osmesa. First of all the configuration options changed, so instead of classic/none we have now true/false. I tried going with -Dosmesa=true in Mesa and -Dosmesa=false in Mesa-drivers but that didn't work out because it apparently wants softpipe or llvmpipe which we don't build in Mesa. So I moved it to Mesa-drivers. Not sure if we want that, perhaps there is a better solution. Other than that I've just ported back two Clover changes for LLVM 12.
Ok. So an update to LLVM12 is already in the works?
Yes, I package LLVM release candidates early on so that I can report issues upstream. It's more or less ready now, I just want to replace one patch by the proper upstream fix.

It's all in <https://build.opensuse.org/project/show/home:aaronpuchert:llvm-next> but I'll need to polish it a bit before I submit the changes. I wasn't planning on doing the actual Mesa update, but if needed I guess I can do it along the way. Best regards, Aaron

Yes, that's one of the issues here. I'm afraid things will get difficult on platforms without any hardware driver. :-( But I will have a try with "auto" or removing this option completely on such platforms. Let's see ...

I think that's a good idea. Currently working on it.

Probably not needed. Things are looking good right now. I expect biggest issues on platforms without hardware driver like s390, ppc64, etc. Thanks, Stefan Public Key available ------------------------------------------------------ Stefan Dirsch (Res. & Dev.)

Can llvmpipe take the role of software rasterization?

Using a gallium driver makes Mesa a larger build (about 1000 files to compile instead of 800), but it appears with that change you can move osmesa back from Mesa-drivers to Mesa. So you can probably undo most of the changes for that. (Just tried it out in my repo.) Since I guess the main point of the split is to have the libraries without LLVM already I think the slightly larger build should be Ok. Best regards, Aaron

Yes, indeed. Thanks for the new submit! Already accepted. Looks good so far. Also on the non-x86_64 platforms!

Hmm strange...for me it makes the build smaller 1200 -> 1000 items and when it comes to build times 208 -> 152 seconds for a local "osc build". Which arch are you building?

That's on x86_64, but I was using -Ddri-drivers=nouveau previously instead of -Dgallium-drivers=swrast. We're throwing away the driver anyway so it doesn't really matter. (Note the rm -f %{buildroot}/%{_libdir}/dri/*_dri.so.) But that meant we couldn't have osmesa in Mesa, so I think your solution is preferable. Best regards, Aaron
