The problem is we're mapping the same texture (but different slices) multiple times simultaneously. The state tracker doesn't support that.
This assertion fails if I put it in st_texture.c:
--- a/src/mesa/state_tracker/st_texture.c
+++ b/src/mesa/state_tracker/st_texture.c

level = stImage->base.Level;
+ /* check that the texture's not already mapped */
+ assert(!stImage->transfer);

return pipe_transfer_map_3d(st->pipe, stImage->pt, level, usage,
x, y, z + stImage->base.Face,
w, h, d, &stImage->transfer);
Gallium allows mapping multiple slices of a 3D texture, but not Mesa's ctx->Driver.MapTextureImage.
This is fixed (probably by 26c41398cc47c0f72259a34406831443238b7ba9). |
