FYI, the flickering on R600 and R700 should be fixed by my latest Mesa commits.

Alright, that fixed the CS rejections as expected.

However the Mesa patch doesn't fix the flickering.

Oops, I only just noticed that my kernel (3.13.2) is rejecting CS buffers:

[  377.460557] radeon :01:00.0: r600_cs_track_check:756 mask 0x0777 |

This is with libdrm 2.4.52 and Mesa f47e5.

I'm seeing additional texture corruption with that patch. I can't say if
nodma,nocpdma helps or makes them worse.

Please try also:

R600_DEBUG=noinvalrange

There will be a severe performance hit though.

Same here: lots of flickering textures. rv730 (HD4xxx).

Present with the tip of the master branch. Not influenced by 7948ed1250.
So far I haven't been able to find a revision that does *not* show the

Retested with latest mesa on kernel 3.13-rc3 and there is no flickering at all
on Cayman.

Do you mean the flickering increases in time even if you stay where you are in
DOTA 2? If so, it may be a different bug. The patch fixed the flickering I was
seeing (and I think it was the same for Peter) in some specific areas (always
the same flickering intensity in a given area, it could be related to some
elements in the are like the river or towers for example).

Peter reopened this bug because the patch was not backported to mesa 9.2 but it
had been fixed for him too when applied manually.

Was fixed on 6950 (I'll test it again later today to be sure things are still
OK). Patches point to evergreen code and above. Marek could tell if it applies
(or if a similar solution should be made) to R700 (HD4XXX).

  Is there any performance regression? If there isn't, I'm okay with the
  revert.
 
 I've run with the original commit 7948ed (+ little workaround) and with it
 remove (both using latest git as of yesterday). I do see a performance
 difference.
 
 I have the following result with the original commit (+ workaround):
 Nexuiz - 58.59
 OpenArea - 59.47
 World of Padman - 59.70
 Urban Terror - 38.03
 Warsow - 157.43
 
 Once removed:
 Nexuiz - 58.47
 OpenArea - 59.20
 World of Padman - 59.63
 Urban Terror - 37.07
 Warsow - 141.55
 
 Now, I should run it again and be sure I'm not enabling vsync here and
 there. Warsow seems to be the one showing the greatest difference since it
 was not hitting the refresh limit.

I ran it again with vsync disabled and, while the scores went up, results are
pretty close from one to another. This time, Warsow scored a bit lower with
7948ed than without it. So, it as no real impact on performances from what I
can see.

Marek,

you ask about, so...
If I'm right, I see some on my poor RV730 AGP under git,
but not with Dota2 or the like 'cause I haven't such stuff.
I see it with Q3A demo (my old testing one) and mesa-demos/
objviewer bobcat.obj/buddha.obj/bunny.obj/GreatLakesBiplaneHP.obj.
Most with high frame rate ones (bobcat.obj).

 fun observation:
 
 Instead of reverting, setting this at the end of r600_cp_dma_copy_buffer()
 appears to fix it for me:
 rctx-b.flags |= R600_CONTEXT_INV_VERTEX_CACHE;
 
 (R600_CONTEXT_INV_CONST_CACHE will also work)
 

Well, if we are using CP DMA to update a constant buffer or vertex buffer, we
need to flush the the apprortiate shader read caches.

 Well, if we are using CP DMA to update a constant buffer or vertex buffer,
 we need to flush the the apprortiate shader read caches.

So, if I understand correctly what you mean, before reverting commit
7948ed1250cae78ae1b22dbce4ab23aceacc6159, the problem was that we were not
flushing correctly (read when expected) caches. Am I understanding correctly?

Why would adding either rctx-b.flags |= R600_CONTEXT_INV_VERTEX_CACHE or
rctx-b.flags |= R600_CONTEXT_INV_CONST_CACHE work in fixing the texture glitch
(which are coming from an unknown buffer type for now) if they are not intended
for the same buffer type?

Also, I'm still interested in benchmarking with and without commit
7948ed1250cae78ae1b22dbce4ab23aceacc6159, so I'll gladly run any suggestion.
Would something like Phoronix test suite be of any interest?

--- Comment #35 from Marek Olšák mar...@gmail.com ---
Feel free to do some benchmarking if you want.

The question is why this code at the end of the function didn't set one of the
flush flags:

r600_flag_resource_cache_flush(rctx, dst);

Constants are usually read with the shader cache and indirect addressing of the
constants goes through the vertex cache. Also some chips don't have the vertex
cache, so they have to use the texture cache instead. That's why both VERTEX
and CONST work for some chips in this situation. The purpose of the flags is to
express what type of buffer was changed. The flushing code will then figure out
which cache should be flushed.

Thing I don't understand about this is that if I instead set the flag just
before r600_flush_emit() is called (2 places) the corruption is still there. I
must be missing something.

[Bug 68451] Texture flicker in native Dota2 in mesa 9.2.0rc1

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=68451

--- Comment #29 from Alexandre Demers alexandre.f.dem...@gmail.com ---
(In reply to comment #27)
 fun observation:
 
 Instead of reverting, setting this at the end of r600_cp_dma_copy_buffer()
 appears to fix it for me:
 rctx-b.flags |= R600_CONTEXT_INV_VERTEX_CACHE;
 
 (R600_CONTEXT_INV_CONST_CACHE will also work)
 
 
 Thing I don't understand about this is that if I instead set the flag just
 before r600_flush_emit() is called (2 places) the corruption is still there.
 I must be missing something.

Your observation also applies to my HD 6950.

The patch reverting 7948ed1250cae78ae1b22dbce4ab23aceacc6159 fixes it for me on
6630M (prime)

The issues I was experiencing:
 - Corruption 1 (polygon facing bottom left)
 - texture flickering

I may give it a try this weekend, but I'm using a HD6950 (I'm also suffering
from texture flickering problem with Dota 2).

Hi,
I am also having this behavior in Dota2. Peter, are you sure
7948ed1250cae78ae1b22dbce4ab23aceacc6159 is the first non-working? Can you try
one earlier commit, 1b40398d024d2ac5c8e8b78d0f4941e2a007de2c, and confirm that
it works? Because, I am seeing the corruption on even earlier (haven't figured
out yet how much earlier).

Maybe I am doing something wrong, I am compiling 32-bit mesa on otherwise
64-bit system, but I can see my own printf()'s I've put in to make sure the
correct library is loaded when running Dota2.

Hello,
I have just checked, commit 1b40398d024d2ac5c8e8b78d0f4941e2a007de2c (+ the 5
patches for Bison 3, above) still works fine.

Current HEAD is still broken.

Hi there,

any update on this one? Can I / do I need to test anything? It's a bit of a
bummer...

Or is this a bug in Dota?

The behaviour is there also with linux-3.11.

That commit does break something, but it was fixed in:

http://cgit.freedesktop.org/mesa/mesa/commit/?id=0d7f087483d014305ec96a84ce5a28355f843c86

In other words, can you checkout 7948ed1250cae78ae1b22dbce4ab23aceacc6159, then
cherry-pick 0d7f087483d014305ec96a84ce5a28355f843c86, and then see if the issue

r600g: only flush the caches that need to be flushed during CP DMA
operations

This should increase performance if constant uploads are done with the CP
DMA,
because only the cache that needs to be flushed is flushed.

Hello,
I guess I'm just really unlucky. Compilation of "required merge" according to
git bisect fails with:

CXXLDlibOSMesa.la
/usr/bin/ld: i386:x86-64 architecture of input file
`../../../../src/mesa/.libs/libmesa.a(ast_expr.o)' is incompatible with i386
output

Which is similar to a bug report here: bug 50754. Adding those variables into
the build script doesn't help (in fact, they've been in before). Looks like I'm
stuffed yet again!

Regardless, you would need to do make clean/distclean after each bisection
step.

this should do the job
$ git cherry-pick $hash

Note: you might need to pick one, two, etc of the hashes depending on where
exactly your HEAD is (i.e. some of the patches may be already applied). In
theory all of those should apply cleanly (git will not complain), although you
may not be so lucky.

Once you take a quick look at the patches mentioned you will see which one
resolves what issue (git show $hash), and you'll be able to pick the correct
ones.

> Also, I've managed to get some screenshots of the corruption, see attached.
Indeed your issue seems different from the one I've mentioned.

--- Comment #11 from Emil Velikov emil.l.veli...@gmail.com ---
(In reply to comment #8)
 Alex, your suggestion doesn't seem to work. 
 
Regardless, you would need to do make clean/distclean after each bisection
step.

 Emil, sorry, I don't really know what to do with these hashes - if you give
 me the git command to run in the repo, I could try that...
 
this should do the job
$ git cherry-pick $hash

Note: you might need to pick one, two, etc of the hashes depending on where
exactly your HEAD is (i.e. some of the patches may be already applied). In
theory all of those should apply cleanly (git will not complain), although you
may not be so lucky.

 I can get current HEAD (58251) compiled, running, and the regression is
 still there. Once I start bisecting, though, the scanner error as in
 comment 5 happens.
 
Once you take a quick look at the patches mentioned you will see which one
resolves what issue (git show $hash), and you'll be able to pick the correct
ones.

 Also, I've managed to get some screenshots of the corruption, see attached.
Indeed your issue seems different from the one I've mentioned.

--- Comment #4 from Peter Kraus  ---
Hello,
did not have a time to bisect yet (seems to be a bit more complex than I
thought, or I'm just daft).

The behaviour is not fixed by yesterday's game update, and it's not fixed in
9.2rc2 either.

What's the best way of doing the bisect if I don't want to pollute my Arch
Linux install?

Cheers.

RE: Emil:
Possibly. I couldn't get a screenshot of the corruption, mine looked a lot
different, but it's definitely possible.

RE: Alex:
I'll try when I get back home and have some time (ie tomorrow). I might try and
follow the bisect of bug 67887, to see whether it's indeed a duplicate.

Wild guess, but can it be bug 67887 ?

Can you bisect to track down what commit caused the problem?
