[Bug 10832] New: Dark Age of Camelot has page fault exception if pixelshaders are enabled

http://bugs.winehq.org/show_bug.cgi?id=10832

Summary: Dark Age of Camelot has page fault exception if
                    pixelshaders are enabled
           Product: Wine
           Version: 0.9.51.
          Platform: PC-x86-64
               URL: http://daoc.goa.com/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

To use the new character models in daoc, pixelshaders need to be enabled. If
they are, a page fault exception occurs as soon as the first character gets
drawn (character selection screen). If I skip the character selection screen,
the same pagefault occurs at a different position in the game. (I have only
uploaded the logs for the selectionscreen version). Pixelshaders have never
worked in this game, but they become more important with every release.

What else have you changed in Wine's default configuration? If you can not
recall, remove ~/.wine directory and reinstall your game.
Also are you using beryl/compiz?

I'm using enlightenment DR17 to run wine games but the composite & AIGLX
extensions are enabled.

I tried different things with the wine config (based on clean .wine):

1. With virtualdesktop/nopixelshaders -> works
2. With virtualdesktop/pixelshaders -> doesn't work
3. Without virtualdesktop, with pixelshaders -> doesn't work
4. With virtualdesktop/pixelshaders/UseGLSL=disabled -> doesn't work (this
works on my core2 laptop with ATI X1600XT Mobile card)

Just tried it with composite extension disabled (and learned that nvidia
drivers don't use aiglx...). I get the same exception.

run of wine-1.0-rc3 with no WINEDEBUG set.

The error is still present in wine-1.0-rc3. This is just the default log
output. If needed, I can do a run with more verbose settings.

The crash is caused by GetDeviceCaps() returning 0 for MaxVertexBlendMatrices.
On a windows machine this returns 4. When wine is patched to also return 4, the
game doesn't crash, but then it doesn't display the player model anymore. (not
with builtin or native d3d9_?? libs).

There's some more mention about this MaxVertexBlendMatrices in Bug 8357 comment
9.

Correction to previous comment.. it works!  The reason the models didnt appear
before was because I was still running a hacked up wine with some stuff
disabled. After using a pristine copy with just the MaxVertexBlendMatrices set
to 4, it seems to work fine!

With max_blends hardcoded to 4 it works for me too, but leads to many lines of

fixme:d3d:transform_worldex >>>>>>>>>>>>>>>>> GL_INVALID_ENUM (0x500) from
glMatrixMode(glMat) @ ../../../wine/dlls/wined3d/state.c / 3551

which probably is to be expected.

I can confirm this bug is still in Wine 1.4 RC5.

The new line to patch in dlls/wined3d/directx.c line 2613 :

if (gl_info->supported[ARB_VERTEX_BLEND])
    {
        glGetIntegerv(GL_MAX_VERTEX_UNITS_ARB, &gl_max);
        gl_info->limits.blends = gl_max;
        TRACE_(d3d_caps)("Max blends: %u.\n", gl_info->limits.blends);
    }
+   gl_info->limits.blends = 4;  /* Dark Age of Camelot hack */
    if (gl_info->supported[EXT_TEXTURE3D])
    {
        glGetIntegerv(GL_MAX_3D_TEXTURE_SIZE_EXT, &gl_max);
        gl_info->limits.texture3d_size = gl_max;
        TRACE_(d3d_caps)("Max texture3D size: %d.\n",
gl_info->limits.texture3d_size);
    }

Is it possible to make this some sort of registry key on a per-application
basis?
Right now, I'm running two copies of WINE. The main version for like Starcraft
II and other apps, and this specially hacked one for Dark Age of Camelot.

Being able to have this as a reg key that only works for specific apps would
solve this problem.

I can confirm this is still an issue with WINE v1.6.1.
I will attach a new debug output. I get "Renderer creation failed" however.
I even tried the patch of hard coding gl_info->limits.blends = 4; and that
doesn't seem to work now.

If there is any way we can have a "quirk" added for game.dll for DAoC to hard
code this limit blend or some kind of fix so that it runs, that would be
fantastic and save me from having to compile in a 32-bit chroot every time.

> From the looks of things, the patch only works with WINE 1.4.1.

Somewhere in WINE 1.5.xx, all the code for pixel shaders changed such that the
small one-line hack no longer works. WINE 1.6.1 almost certainly shares this
new codebase so I've no idea where to go from here.

In current Wine you can modify "caps->MaxVertexBlendMatrices" in
wined3d_get_device_caps() instead, and it should have about the same effect as
the hack attached to this bug. This bug is essentially a duplicate of bug 6955
though.
