 * Three debug levels are defined.

116
 * The macro definition of DRM_DEBUG is used.
117
 * 	DRM_DEBUG(fmt, args...)
118
 * 	The debug info by using the DRM_DEBUG can be obtained by adding
119
 * 	the boot option of "drm.debug=1".
120
 *
121
 * drm_driver level can be used in the specific drm driver. It is used
122
 * to add the debug info related with the drm driver. For example:
123
 * i915_drv, i915_dma, i915_gem, radeon_drv,
124
 * 	The macro definition of DRM_DEBUG_DRIVER can be used.
125
 * 	DRM_DEBUG_DRIVER(fmt, args...)
126
 * 	The debug info by using the DRM_DEBUG_DRIVER can be obtained by
127
 * 	adding the boot option of "drm.debug=0x02"
128
 *
129
 * drm_kms level can be used in the KMS code related with specific drm driver.
130
 * It is used to add the debug info related with KMS mode. For example:
131
 * the connector/crtc ,
132
 * 	The macro definition of DRM_DEBUG_KMS can be used.
133
 * 	DRM_DEBUG_KMS(fmt, args...)
134
 * 	The debug info by using the DRM_DEBUG_KMS can be obtained by
135
 * 	adding the boot option of "drm.debug=0x04"
136
 *
137
 * If we add the boot option of "drm.debug=0x06", we can get the debug info by
138
 * using the DRM_DEBUG_KMS and DRM_DEBUG_DRIVER.
139
 * If we add the boot option of "drm.debug=0x05", we can get the debug info by
140
 * using the DRM_DEBUG_KMS and DRM_DEBUG.
