Screenshot of broken video

Intro videos in the game Call of Duty 4 (running with Wine) no longer renders
correctly, bisecting leads to this:

    r600g: Replace needless flush in texture upload.

    Replace pipe->flush() with pipe->texture_barrier() in
    the texture upload path for the staging texture.
    This should be enough to get data out of the gpu
    caches ready to be read for texture fetch.

Adding the flush back fixes the problem.

Also a problem on radeonsi.

Apitrace of the problem:
https://www.dropbox.com/s/ibt9iu15x4mxw9q/cod4.trace?dl=0

I'm getting a lot of errors when replaying the trace, so I guess it's possible
the game or Wine is doing something wrong:

100824: message: major api error 1: GL_INVALID_OPERATION in glTexImage3D(bad

Setting StrictDrawOrdering in Wine to enabled gets working videos again, but at
a severe performance cost.

Hi Sven, thanks for the apitrace. I can confirm that there is garbage in some
of the first frames of the apitrace, e.g. Frame 11 @77450. I'm going to look in
more detail, though the many error messages do hint at an application bug.

I just tried Wine Staging with the CSMT (Command stream multithreading)
patches, and the videos play fine there, so I think it really is a problem with
Wine.

--- Comment #7 from Nicolai Hähnle <nhaehnle@gmail.com> ---
This is an application bug (though I don't know whether the fault lies with
Wine or with CoD4): there is insufficient synchronization between different
contexts.

If you look e.g. at Frame 5, there is a sequence of glTexSubImage2D calls for
textures 64 to 66 running in context 3.

The command sequence switches to context 2 in call 75827, and the textures are
used in call 76024, still on context 2 and without any flush or fence command
in between to ensure that the TexSubImage commands are actually executed.
