Hello,
I am new to DRI hacking, and I am looking for some guidance. I am trying to
get the Neverwinter Nights Toolset to work under wine (http://nwwine.beergeek.net). I
have hacked wine a bit to get it working for most people, but I am having problems
with the r128 drivers that other people using different cards are not seeing. I am
using a Rage Mobility 128 with the latest CVS DRI and X 4.2. I have two problems.
1) Some textures don't appear (or may not repeat) when in 1600x1200 mode (they work
fine when X is in 1280x1024 or 1024x768)
Wine makes the following series of calls
# Set GL_TEXTURE_WRAP_S to GL_REPEAT
trace:opengl:wine_glTexParameteri (3553, 10242, 10497)
# Set GL_TEXTURE_WRAP_T to GL_REPEAT
trace:opengl:wine_glTexParameteri (3553, 10243, 10497)
When in 1600x1200 the 1st call produces a GLError of GL_INVALID_VALUE (no error in
other resolutions) the second call seems to succeed. So I think that call failing is
the problem. However I looked at the mesa source in CVS and this doesn't make sense;
these parameter seem valid. Is the GL_INVALID_VALUE being produced at a higher level
than _mesa_TexParameterfv? How could this be a product of the resolution?
The above problem occurs in both XFree 4.1 version and in CVS.
2) Assert fails in r128_texstate.c
The texture that r128UpdateTextureUnit has been passed is null. I think what happens
is that the texture is deleted and set to null. Then a new texture is bound to the
old spot with glBindTexture, but no new texture is created.
r128_texstate.c:494: r128UpdateTextureUnit: Assertion `t' failed.
This happens when a window is created on top of another window and they both have
renderings in them. The new window works fine (I believe rendering to the window
below it is stopped while the new window is pen), but when the new window is closed
(and the old window becomes the focus), this assertion fails.
This seems to be a regression. The XFree 4.1 version does not have this problem.
I would greatly appreciate it if one of you could point me in the right direction so I
can fix the bug in the driver.
Thanks!
ryan
