It's fixed, but I noticed that it would work also with:

functions->CopyPixels = _mesa_meta_CopyPixels;
functions->DrawPixels = _mesa_meta_DrawPixels;
if (radeon->radeonScreen->kernel_mm) {
    functions->ReadPixels = radeonReadPixels;
}

Is this better than current?

if (radeon->radeonScreen->kernel_mm) {
    functions->CopyPixels = _mesa_meta_CopyPixels;
    functions->DrawPixels = _mesa_meta_DrawPixels;
    functions->ReadPixels = radeonReadPixels;
}

Should be fine.  Care to create a patch?

Did you actually test glReadPixels() with that?

Err, I mean glCopyPixels and glDrawPixels.

Created an attachment (id=34007)
 --> (http://bugs.freedesktop.org/attachment.cgi?id=34007)
enable meta ops for draw/coopy pixels

Seems to work ok here.

I tested only the game, but shouldn't _mesa_meta_DrawPixels and
_mesa_meta_CopyPixels be already the default BTW?

They weren't enabled until that patch.
