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.
If ef7e0b39a24966526b102643523feac765771842 is bad, you need llvm-3.5 and start
from older mesa commit.

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?

Sorry to bring you bad news, but that commit was reverted soon after it was
committed.

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.

That one has been reverted as well. Can you try bisecting again with that one
reverted?

How would you revert a commit then bisect?

67a77ecdec3ba701eb63783535c43abf6eb1ab29 is the first bad commit
commit 67a77ecdec3ba701eb63783535c43abf6eb1ab29
Author: Marek Olšák <marek.olsak@amd.com>

    radeonsi: don't use TC L2 for updating descriptors on SI

    It's causing problems, because we mix uncached CP DMA with cached
WRITE_DATA
    when updating the same memory.

    The solution for SI is to use uncached access here, because CP DMA doesn't
    support cached access.

    CIK will be handled in the next patch.

Revert TC Patch

Seems like reverting all TC commits fixes the issue ...
Tested the patch on Master

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.

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)
