+ * Three debug levels are defined.
+ * drm_core, drm_driver, drm_kms
+ * drm_core level can be used in the generic drm code. For example:
+ *      drm_ioctl, drm_mm, drm_memory
+ * The macro definiton of DRM_DEBUG is used.
+ *      DRM_DEBUG(fmt, args...)
+ *      The debug info by using the DRM_DEBUG can be obtained by adding
+ *      the boot option of "drm.debug=1".
+ *
+ * drm_driver level can be used in the specific drm driver. It is used
+ * to add the debug info related with the drm driver. For example:
+ * i915_drv, i915_dma, i915_gem, radeon_drv,
+ *      The macro definition of DRM_DEBUG_DRIVER can be used.
+ *      DRM_DEBUG_DRIVER(fmt, args...)
+ *      The debug info by using the DRM_DEBUG_DRIVER can be obtained by
+ *      adding the boot option of "drm.debug=0x02"
+ *
+ * drm_kms level can be used in the KMS code related with specific drm driver.
+ * It is used to add the debug info related with KMS mode. For example:
+ * the connector/crtc ,
+ *      The macro definition of DRM_DEBUG_KMS can be used.
+ *      DRM_DEBUG_KMS(fmt, args...)
+ *      The debug info by using the DRM_DEBUG_KMS can be obtained by
+ *      adding the boot option of "drm.debug=0x04"
+ *
+ * If we add the boot option of "drm.debug=0x06", we can get the debug info by
+ * using the DRM_DEBUG_KMS and DRM_DEBUG_DRIVER.
+ * If we add the boot option of "drm.debug=0x05", we can get the debug info by
