/* |
* 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 definition 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". |
* 4 debug categories are defined: |
* |
* 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" |
* CORE: Used in the generic drm code: drm_ioctl.c, drm_mm.c, drm_memory.c, ... |
* This is the category used by the DRM_DEBUG() macro. |
* |
* 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" |
* DRIVER: Used in the vendor specific part of the driver: i915, radeon, ... |
* This is the category used by the DRM_DEBUG_DRIVER() macro. |
* |
* 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 |
* using the DRM_DEBUG_KMS and DRM_DEBUG. |
* KMS: used in the modesetting code. |
* This is the category used by the DRM_DEBUG_KMS() macro. |
* |
* PRIME: used in the prime code. |
* This is the category used by the DRM_DEBUG_PRIME() macro. |
* |
* Enabling verbose debug messages is done through the drm.debug parameter, |
* each category being enabled by a bit. |
* |
* drm.debug=0x1 will enable CORE messages |
* drm.debug=0x2 will enable DRIVER messages |
* drm.debug=0x3 will enable CORE and DRIVER messages |
* ... |
* drm.debug=0xf will enable all messages |
* |
* An interesting feature is that it's possible to enable verbose logging at |
* run-time by echoing the debug value in its sysfs node: |
* # echo 0xf > /sys/module/drm/parameters/debug |
