          Priority: medium
            Bug ID: 64257
          Assignee: dri-devel@lists.freedesktop.org
           Summary: RS880 issues with r600-llvm-compiler
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: mike@fireburn.co.uk
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

Hi

Kwin starts with a black screen if I use r600-llvm-compiler on my RS880

When I switched off the llvm parts and just ran glxgears using
r600-llvm-compiler the gears looked like they were layered wrongly and slightly
darker

I'm not sure when this regression appeared - I'm guessing within the last two
weeks - I mostly ssh into the box

I'm always running the latest llvm, clang, libdrm and mesa

I didn't see anything strange in my dmesg or .xsession-errors  or from the
glxgears text output

Could this be due to RS880 being singled out in llvm as a separate processor
variant?

ie r600g/llvm: Update radeon family mappings for LLVM backend or [PATCH 1/2]
R600: Add some new processor variants

Any chance you could bisect?  It might be a duplicate of bug 64193.

Is it mesa or llvm that needs bisecting or both?

I just pushed the Mesa patch that updates the GPU mappings to account for the
new processors in LLVM.  Can you re-test with the latest code from the git

I too can confirm that the two patches to llvm fix things for me

Is there any chance they could be applied to llvm 3.3 before it's released?

It's possible that the recent scheduling changes have caused an unrelated
regression.  Does kwin render correctly if you use the LLVM 3.3 branch?

No time currently to test my rv670 or bisect, but on current heads my rv790 is
rendering Unigine heaven with various incorrect hues.

Does a similar regression happens on less complex application ? (ie mesa demo)

Demos look OK, and a quick run of openarena and nexuix looked OK.

etqw is showing some transient corruptions.

Was going to try and pin this down last night but ended up finding a further
regression instead.

commit 061ff3409d4f6db313448fa8d916313233789516

    Setting the default value (fixes CRT assertions about uninitialized
variable use when doing debug MSVC builds), and fixing coding style.

borks everything for me.

On my rv790 the heaven regression is caused by -

OK I'm just back and I've recompiled everything from master - unfortunately
things have regressed further. I'm not sure if there's colour corruption or not
but things do look a little funky

fixes the regression caused by -

commit 061ff3409d4f6db313448fa8d916313233789516

so most things work on rv770.

Heaven is still wrong, though.

still the same. 

chrome still shows the triangles instead of the boy in the boat (even worse
than before) and firefox does not render the boy at all.

Doesn't fix heaven or pearl boy on my rv790, though in the case of pearl boy
corruption didn't start until I dived.

looks like my chrome version (27) has a bug with coordinates, so ignore this

All of the proposed fixes have been merged to the LLVM tree, so what would be
helpful now is if people could post the output of R600_DEBUG=vs,fs,ps,sbdisasm
from the applications that don't work.  It would also be helpful if you could
post the same shader dumps from an older version of Mesa/LLVM when the
application was working.

I attached the output of firefox

the commit mentioned in comment 42 almost fixes the misrendering, but not
completely. R600_DEBUG=sbdisasm crashes, so I cannot provide the output with
it.
Anyway, attaching output with current mesa/llvm and commits from comment 42.
The diff is really short ...

Can you post a backtrace from the crash with R600_DEBUG=sbdisasm This may
provide a clue as to what is wrong.

Work Around

It looks like the stack size calculations are wrong in some cases, does this
patch help?

seems to be fixed in master now, but using the commits in comment 42 it crashes

Force max tex size of 8

Does this patch help ?
I assumed a max tex clause size of 16 for anything from HD4000 using mesa
classic backend as reference, but apparently the hw cannot support more than 8
instructions in a tex clause.
On the other hand I don't think that classic backend create clauses that big,
so it may be the reason this wrong limit was unspotted.

6xx has a max tex/vtx clause size of 8.
7xx+ has a max tex/vtx clause size of 16.

In CF_WORD1, make sure you are setting the MSB of the count field.  Bits 12:10
and bit 19 make up the total count field.  I suspect you are not setting bit 19
properly.

Properly set COUNT_3

Indeed, I was always setting COUNT_3 to 0.

This new patch should solve the issue (at least if it's related to tex clause
size). I can't test on Unigine because Unigine doesn't want to start anymore
since I updated my fedora beta, however oversatured hue in some Lightmark scene
is gone.

This doesn't fix it and I also got a GPU reset.

The other patch - Force max tex size of 8 does fix it.

Dos this new patch help ? It's almost the same as the previous one, but I

vincent, it seems you applied the patch to master already. I cannot find any
difference with perl boy demo. Can someone provide me a link to heaven 3.0? I
can only find 4.0 which requires opengl 3.3...

The patch - doesn't apply maybe it's the wrong one -

Forgot to put that you need to run heaven 3.0 like -

MESA_EXTENSION_OVERRIDE=-GL_ARB_shader_bit_encoding 
force_glsl_extensions_warn=true  ./heaven

regarding crash in comment 57, there seems to be something wrong with cosine:

https://www.khronos.org/registry/webgl/conformance-suites/1.0.2/conformance/glsl/functions/glsl-function-cos.html

reproduces the crash.

Trig functions need slightly different setup on r6xx and r7xx+.  See
tgsi_setup_trig() in r600_shader.c:

/*
 * r600 - trunc to -PI..PI range
 * r700 - normalize by dividing by 2PI
 * see fdo bug 27901

I mean it cannot find the intrinsic at all:

# ./Release/bin/llc < test/CodeGen/R600/llvm.sin.ll -march=r600 -mcpu=r600
LLVM ERROR: Cannot select: 0x8a5570: f32 = fsin 0x8a5670 [ORD=2] [ID=3]

    0x8a5970: f32 = Register %T0_X [ID=1]

litte different with eg. -mcpu=hainan:

Add a cos/sin pattern

Andy, does current master work on your rv790 and Unigine ?

Marc, can you try the attached patch and Unigine Heaven ? I'm not sure it'll
work (the cos/sin pattern does not trunc anything, but it should at least not
crash)
