94 | * Three debug levels are defined. | |
95 | * drm_core, drm_driver, drm_kms | |
96 | * drm_core level can be used in the generic drm code. For example: | |
97 | * drm_ioctl, drm_mm, drm_memory | |
98 | * The macro definiton of DRM_DEBUG is used. | |
99 | * DRM_DEBUG(fmt, args...) | |
100 | * The debug info by using the DRM_DEBUG can be obtained by adding | |
101 | * the boot option of "drm.debug=1". | |
102 | * | |
103 | * drm_driver level can be used in the specific drm driver. It is used | |
104 | * to add the debug info related with the drm driver. For example: | |
105 | * i915_drv, i915_dma, i915_gem, radeon_drv, | |
106 | * The macro definition of DRM_DEBUG_DRIVER can be used. | |
107 | * DRM_DEBUG_DRIVER(fmt, args...) | |
108 | * The debug info by using the DRM_DEBUG_DRIVER can be obtained by | |
109 | * adding the boot option of "drm.debug=0x02" | |
110 | * | |
111 | * drm_kms level can be used in the KMS code related with specific drm driver. | |
112 | * It is used to add the debug info related with KMS mode. For example: | |
113 | * the connector/crtc , | |
114 | * The macro definition of DRM_DEBUG_KMS can be used. | |
115 | * DRM_DEBUG_KMS(fmt, args...) | |
116 | * The debug info by using the DRM_DEBUG_KMS can be obtained by | |
117 | * adding the boot option of "drm.debug=0x04" | |
118 | * | |
119 | * If we add the boot option of "drm.debug=0x06", we can get the debug info by | |
120 | * using the DRM_DEBUG_KMS and DRM_DEBUG_DRIVER. | |
121 | * If we add the boot option of "drm.debug=0x05", we can get the debug info by | |
122 | * using the DRM_DEBUG_KMS and DRM_DEBUG. | |
