Alright so, before upgrading to 10.5.1 I was on 10.4.6 and a game I play a lot, Counter Strike GO (Available on Steam) was running just fine at good performance with nothing weird coming up on screen. After updating on 10.5.1 I am getting lots of white flickering on certain parts of the game (walls or objects) as well as lines that go accross objects. It appears almost as if it is GPU artifacting, although it is not because Minecraft and other games do not produce any of these weird effects. What can do be done to solve the issue? CSGO is a proprietary game although Valve is pretty good at giving support for Linux I would assume so maybe some things can be done. I have no clue what kind of log output would be helpful, I would assume dmesg and Xorg.0.log yes? I will be adding them in shortly. Specs AMD 7950 3GB Arch Linux 3.19.2 kernel
Created attachment 114498 [details] Xorg Log Xorg Log after running the game
Created attachment 114499 [details] dmesg output dmesg output after running the game, experiencing the artifacts/flickering/issues listed in OP and closing the game.
Does it still happen with current Mesa Git master? If so, can you bisect?
(In reply to Michel Dänzer from comment #3) > Does it still happen with current Mesa Git master? If so, can you bisect? The mesa-git package available in the arch linux user repository is not working at the moment so this may take a while. I found this https://wiki.archlinux.org/index.php/Bisecting_bugs essentially do I just follow these steps? This is a bit out of my scope of knowledge.

Alright I just, I do not have enough knowledge to follow that tutorial I tried and I am just failing miserably and I can't understand what I am doing. I upgraded my system to mesa-git (10.6-devel) and I still have the issue so the issue IS present on 10.6. Hopefully there is someone at the mesa team that plays games and can test CSGO on AMD hardware?
Andre ff you use yaourt grab pkgs by: yaourt -G mesa-git and yaourt -G lib32-mesa-git, and make it and install (cd mesa-git; makepkg -si; and the same for lib32-mesa-git) CS GO is 32bit (i belive) app so you need bisect only lib32-mesa-git: Try commit: http://cgit.freedesktop.org/mesa/mesa/commit/?id=ef7e0b39a24966526b102643523feac765771842 It's first one I can build against llvm-3.6, it's probably old enough to run CS:GO without issues but you have to be sure: $cd lib32-mesa-git $cd src/mesa $git checkout ef7e0b39a24966526b102643523feac765771842 $cd ../.. $makepkg -efsi //Try CS:GO and if it's ok, let's bisect: $cd src/mesa $git bisect start //git bisect good _commit_when_CSGO_ok $git bisect good ef7e0b39a24966526b102643523feac765771842 //git bisect bad _commit_when_you_see_issue //you may use mesa 10.5.1 release note: http://cgit.freedesktop.org/mesa/mesa/commit/?id=11c0ff60ef19cca84452aa989fb8bb25127473e0 $git bisect bad 11c0ff60ef19cca84452aa989fb8bb25127473e0 //now you can see info about need check some commit $cd ../.. $makepkg -efsi //and now try CS:GO //if CS GO has issues still $cd src/mesa $git bisect bad //or if CS GO runs without issues $cd src/mesa $git bisect good -->GOTO //now you can see info about need check some commit //you need check another commit again and again... and again until it gives to you "first bad commit" and this "first bad commit" is wanted by Michel I hope it help a bit.

Alright so I decided to give this a try since I have some time. I downloaded the mesa-git and lib32-mesa-git tarballs manually and ran makepkg -s then I went into src/mesa and used that command to put in the commit and went back to the main directory and did makepkg -s instead of makepkg -efsi because I don't know what that does...I believe -i installs it but I would prefer it to make .tar.xz packages so I can remove this version using pacman....I am just afraid to screw up my system. So I did this for mesa and lib32-mesa to ensure nothing would go wrong, and it seemed to have built mesa-git 10.6.0_devel.... Alright, I did sudo pacman -U to install the .tar.xz packages that were built logged out/in and loaded up CSGO. The graphical issues I have been talking about are still there. I went into /src/mesa did bit bisect start and then git bisect bad and put the ef7e0b39a24966526b102643523feac765771842 commit. I honestly have no clue what I am doing but I then did the same steps initially of building the package but did commit cb154bb22116910c462f7a83f4401bd01e15c34d which is a commit for 10.4.7 since the entire 10.4.x series were fine with CSGO and only noticed issues since 10.5 came out. I guess ill move up from 10.4.7 and there? Again I did makepkg -s and the .tar.xz that were made were the same ones as before. I am confused if I am actually doing anything here.
I don't have the skill to this. Is it possible I could purchase the game for one of the developers through Steam and they can try and solve this? Offtopic but I think this is an important field, games need to be tested and make sure they work. Granted majority of distros arent using 10.5 however eventually they will catch up and if the bugfixes haven't been solved this could prevent linux users from playing games, forced to go back into windows to (what I am experiencing now) and could even prevent new users from transitioning to Linux.
Certain Mesa devs are able to get this game for free, as well as other Valve games. Hopefully this may help solve the bug as someone working in Mesa can use the game on their machines? http://lists.freedesktop.org/archives/dri-devel/2015-April/081045.html

After I posted the comment I noticed it was reverted. I compiled 82b7ee62fc4bbe014f61a60bccf694b706c7247d and the artifacts are still present. There might be two different changes that cause a similar bug? I'll try to narrow it down.

So I came to check out if there was anything new and I see that there are some of you working on fixing the bug? Thank You! I really appreciate it as I have no clue how to do this on my own. I don't know what else I can do to help, only that (you guys probably know this already) the bug is still present on Mesa 10.6...just thought I would let you know in case you guys didnt (you probably do). Thanks a lot again for looking into the issue.

How would you revert a commit then bisect?

What happens if you change SI_NUM_CONTEXTS to 32 in src/gallium/drivers/radeonsi/si_descriptors.c ? Do you have Tahiti, Pitcairn, or something else?
We can't revert it, because it would cause other issues. Your patch is wrong, because it reverts a lot of unrelated things too. I think the proper fix is to use the constant engine. Or upload descriptors without CP_DMA and WRITE_DATA, only using the CPU to upload them.
Created attachment 117229 [details] make log I have a Tahiti (7950) GPU for your information. When I set SI_NUM_CONTEXTS to 32 in si_descriptors.c, I get multiple compile errors. I have tried to set it with define SI_NUM_CONTEXTS 32, define SI_NUM_CONTEXTS=32, and SI_NUM_CONTEXTS=32.
Nevermind, I got it to compile with 'SI_NUM_CONTEXTS=32;', but it seems to have done nothing to help the artifacting/glitching.
I would like to notify everyone that I have tried the latest mesa available from git (both mesa and lib32-mesa from git, via the AUR on Arch Linux) and there seems to be no artificating! I do not know what you guys did but it seemed to have worked. Thank you so much, I appreciate it! I downloaded mesa-demo from official ach repo, I am not aware if that is okay but when I run glxinfo | grep "OpenGL version" it shows OpenGL version string: 3.0 Mesa 11.0.0-devel (git-d6d7515)
