+ * The 'type' parameter identifies whether the shader state contains TGSI
+ * tokens, etc. If the driver returns 'PIPE_SHADER_IR_TGSI' for the
+ * 'PIPE_SHADER_CAP_PREFERRED_IR' shader param, the ir will *always* be
+ * 'PIPE_SHADER_IR_TGSI' and the tokens ptr will be valid. If the driver
+ * requests a different 'pipe_shader_ir' type, then it must check the 'type'
+ * enum to see if it is getting TGSI tokens or its preferred IR.
+ *
+ * TODO pipe_compute_state should probably get similar treatment to handle
+ * multiple IR's in a cleaner way..
+ *
+ * NOTE: since it is expected that the consumer will want to perform
+ * additional passes on the nir_shader, the driver takes ownership of
+ * the nir_shader. If state trackers need to hang on to the IR (for
+ * example, variant management), it should use nir_shader_clone().
