131 * Three debug levels are defined.
132 * drm_core, drm_driver, drm_kms
133 * drm_core level can be used in the generic drm code. For example:
134 * drm_ioctl, drm_mm, drm_memory
135 * The macro definition of DRM_DEBUG is used.
136 * DRM_DEBUG(fmt, args...)
137 * The debug info by using the DRM_DEBUG can be obtained by adding
138 * the boot option of "drm.debug=1".
139 *
140 * drm_driver level can be used in the specific drm driver. It is used
141 * to add the debug info related with the drm driver. For example:
142 * i915_drv, i915_dma, i915_gem, radeon_drv,
143 * The macro definition of DRM_DEBUG_DRIVER can be used.
144 * DRM_DEBUG_DRIVER(fmt, args...)
145 * The debug info by using the DRM_DEBUG_DRIVER can be obtained by
146 * adding the boot option of "drm.debug=0x02"
147 *
148 * drm_kms level can be used in the KMS code related with specific drm driver.
149 * It is used to add the debug info related with KMS mode. For example:
150 * the connector/crtc ,
151 * The macro definition of DRM_DEBUG_KMS can be used.
152 * DRM_DEBUG_KMS(fmt, args...)
153 * The debug info by using the DRM_DEBUG_KMS can be obtained by
154 * adding the boot option of "drm.debug=0x04"
155 *
156 * If we add the boot option of "drm.debug=0x06", we can get the debug info by
157 * using the DRM_DEBUG_KMS and DRM_DEBUG_DRIVER.
158 * If we add the boot option of "drm.debug=0x05", we can get the debug info by
159 * using the DRM_DEBUG_KMS and DRM_DEBUG.
