I believe that restriction might only apply to swizzled surfaces.

Hm, but in my case it apparently worked fine... so, may be check is
overrestrictive?

I also tried to apply this path on top of mesa version indicated above
((git-93161be)

and got this in terminal:

This is a bit strange, this demo from ~2002 era, and apparently was  working
fine on older nvidia hardware. And on nouveau, until this  commit.  I will
retest just for making sure it doesn't flood my dmesg with errors

You should be seeing errors about invalid values in dmesg for 0208 or some
similar method. I'm guessing that the zeta buffer is used in such a way that
things happen to work out, but the card doesn't really support it.

src/gallium/include/pipe/p_format.h:   PIPE_FORMAT_B8G8R8A8_UNORM  = 1,
src/gallium/include/pipe/p_format.h:   PIPE_FORMAT_Z16_UNORM   =
16,

Not a valid combo, AFAIK.

just tried to comment  out zbuf disabling, rendering is ok, no errors o.o May
be because nv43 uses z-compression?

kbuildsycoca running...


important part seems to be:
"Mismatched color and zeta formats, ignoring zeta."

I also tried to disable PIPE_CAP_BUFFER_MAP_PERSISTENT_COHERENT , but this not
fixed my bug.

(In reply to Andrew Randrianasulu from comment #11)
> "Mismatched color and zeta formats, ignoring zeta."

Yeah, as I suspected... unfortunately there's not a ton you can do besides
fixing the issue. The problem is that you can't render to a 32-bit color format
(e.g. RGBA8) while using a 16-bit zeta (Z16), and conversely you can't render
to a 16-bit color format (e.g. RGB565) while using a 32-bit zeta (Z24S8).

My current solution to this problem is to just not set the zeta buffer and move
on with life. This leads to incorrect rendering, but at least no hangs.

The proper solution is to have 2 depth textures that you copy to and fro and
set the "right" one for the given color format. Ideally while minimizing the
number of copies.

Older wine reacted the same (illegal instruction), so this is not something
added with new wine version.

This machine lacks SSE2, obviously ..may be apitrace silently compiles in some
SSE2+ code?

--- Comment #6 from Andrew Randrianasulu  ---
Updating wine (to version 1.7.51-staging, from
http://www.slackware.com/~alien/slackbuilds/wine/pkg/14.1/) resulted in
correctly disabled Vsync, but rendering still broken in the same way.

Moreover, attempt to use latest apitrace (command line: 
~/src/apitrace/apitrace trace /usr/bin/wine GLExcess.exe ) only resulted in
illegal instruction (?!)

[Nouveau] [Bug 92306] GL Excess demo renders incorrectly on nv43

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=92306

--- Comment #5 from Andrew Randrianasulu  ---
Hm, apparently this is regression - tried few mesa versions - 10.1.6 was OK,
but 10.2.9 already broken.

Attempt to disable few new (in 10.2) extensions not fixed this.
"Mesa 10.2.9 implementation error: Trying to disable a permanently enabled
extension: GL_ARB_multi_bind" - this one can't be disabled, it seems
(commandline used  MESA_EXTENSION_OVERRIDE="-GL_ARB_multi_bind" wine
GLExcess.exe)

MESA_EXTENSION_OVERRIDE="-GL_ARB_buffer_storage" wine GLExcess.exe - not
resulted in anything.

Apparently those two types of corruption related (no image and parts of scene 
filled with rainbow  lines) - at least they both started to appear in 10.2.9

correct software rendering

It shows some landscape, even if at 1 fps.

dmesg

I think you can ignore locking-related warnings. But I can retry with 4.3-rc4
mainline, if you prefer (again, will need some time to compile it)

Another type of image corruption

Probably need its own bugreport. It always happen at same place in scene - so,
not random. Nearly looks like some garbage instead of (guess) alpha channel of
texture?
