128
 * The macro definition of DRM_DEBUG is used.

 * 	DRM_DEBUG(fmt, args...)
130
 * 	The debug info by using the DRM_DEBUG can be obtained by adding
131
 * 	the boot option of "drm.debug=1".
132
 *
133
 * drm_driver level can be used in the specific drm driver. It is used
134
 * to add the debug info related with the drm driver. For example:
135
 * i915_drv, i915_dma, i915_gem, radeon_drv,
136
 * 	The macro definition of DRM_DEBUG_DRIVER can be used.
137
 * 	DRM_DEBUG_DRIVER(fmt, args...)
138
 * 	The debug info by using the DRM_DEBUG_DRIVER can be obtained by
139
 * 	adding the boot option of "drm.debug=0x02"
140
 *
141
 * drm_kms level can be used in the KMS code related with specific drm driver.
142
 * It is used to add the debug info related with KMS mode. For example:
143
 * the connector/crtc ,
144
 * 	The macro definition of DRM_DEBUG_KMS can be used.
145
 * 	DRM_DEBUG_KMS(fmt, args...)
146
 * 	The debug info by using the DRM_DEBUG_KMS can be obtained by
147
 * 	adding the boot option of "drm.debug=0x04"
148
 *
149
 * If we add the boot option of "drm.debug=0x06", we can get the debug info by
150
 * using the DRM_DEBUG_KMS and DRM_DEBUG_DRIVER.
151
 * If we add the boot option of "drm.debug=0x05", we can get the debug info by
152
 * using the DRM_DEBUG_KMS and DRM_DEBUG.
