mt->total_height *is* used for state setup, for calculating qpitch in brw_miptree_get_vertical_slice_pitch(), which is transitively called from brw_upload_image_surfaces(). mt->total_width is never used for miptrees created for DRIimage's, as far as I can tell. Regardless, I believe that all code that accesses DRIimage::offset,tile_x,tile_y is horribly broken, and this patch accordingly does not alter the entropy. For consistency with intel_image_target_renderbuffer_storage(), and no other reason, this patch is Reviewed-by: Chad Versace <chadvers...@chromium.org> Please update the commit message to mention that at least mt->total_width is used. > src/mesa/drivers/dri/i965/intel_mipmap_tree.c | 4 ++-- > 1 file changed, 2 insertions(+), 2 deletions(-) > > diff --git a/src/mesa/drivers/dri/i965/intel_mipmap_tree.c > b/src/mesa/drivers/dri/i965/intel_mipmap_tree.c > index 3bc6827..a1be37e 100644 > --- a/src/mesa/drivers/dri/i965/intel_mipmap_tree.c > +++ b/src/mesa/drivers/dri/i965/intel_mipmap_tree.c > @@ -922,10 +922,10 @@ intel_miptree_create_for_dri_image(struct brw_context > *brw, > return NULL; > > mt->target = target; > - mt->total_width = image->width; > - mt->total_height = image->height; > mt->level[0].slice[0].x_offset = image->tile_x; > mt->level[0].slice[0].y_offset = image->tile_y; > + mt->total_width += image->tile_x; > + mt->total_height += image->tile_y; > > /* From "OES_EGL_image" error reporting.
