I'm trying to enable GLX_EXT_texture_from_pixmap in direct rendering for swrast. After applying patches given in this thread glxinfo shows TFP on GLX extensions string, but correlated functions don't work.
1) I found that GetGLXDRIDrawable() inside drisw_bind_tex_image() returns NULL, so function fails due to line: if (pdraw != NULL) { becouse there is no needed GLXDrawable key inside hash table if (__glxHashLookup(priv->drawHash, drawable, (void *) &pdraw) == 0) return pdraw; return NULL; 2) I took a look at i915 dri2 driver and i found this hash is normally added inside CreateDRIDrawable() function in glx_pbuffer.c at lines: if (__glxHashInsert(priv->drawHash, glxdrawable, pdraw)) { (*pdraw->destroyDrawable) (pdraw); return; /* FIXME: Check what we're supposed to do here... */ } but this function fails on swrast for me due to: pdraw = psc->driScreen->createDrawable(psc, drawable, glxdrawable, config); if (pdraw == NULL) { fprintf(stderr, "failed to create drawable\n"); return; } and finally due to condition inside driCreateDrawable() in drisw_glx.c: /* Old dri can't handle GLX 1.3+ drawable constructors. */ if (xDrawable != drawable) return NULL; 3) I tried to comment out above condition, but then i get crash inside swrastGetImage() in drisw_glx.c. Anybody can help? /Sylwester _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
