 /**
- * Same as util_blitter_copy_texture with the capabilities of util_blitter_blit,
- * but dst and src are pipe_surface and pipe_sampler_view, respectively.
- * The mipmap level and dstz are part of the views.
+ * This is a generic implementation of pipe->blit, which accepts
+ * sampler/surface views instead of resources.
+ *
+ * The layer and mipmap level are specified by the views.
  *
  * Drivers can use this to change resource properties (like format, width,
  * height) by changing how the views interpret them, instead of changing
- * pipe_resource directly. This is usually needed to accelerate copying of
- * compressed formats.
+ * pipe_resource directly. This is used to blit resources of formats which
+ * are not renderable.
  *
  * src_width0 and src_height0 are sampler_view-private properties that
  * override pipe_resource. The blitter uses them for computation of texture
