This adds an array of pipe_transfers to st_texture_image. Each transfer is for mapping a single layer. v2: allocate the array of transfers on demand --- diff --git a/src/mesa/state_tracker/st_cb_texture.c b/src/mesa/state_tracker/st_cb_texture.c index 304dc91677e..97bba8b7da5 100644 --- a/src/mesa/state_tracker/st_cb_texture.c +++ b/src/mesa/state_tracker/st_cb_texture.c @@ -175,6 +175,10 @@ st_FreeTextureImageBuffer(struct gl_context *ctx, _mesa_align_free(stImage->TexData);
