-/*
- * The following categories are defined:
- *
- * 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.
- *
- * DRIVER: Used in the vendor specific part of the driver: i915, radeon, ...
- * This is the category used by the DRM_DEBUG_DRIVER() macro.
- *
- * 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.
- *
- * ATOMIC: used in the atomic code.
- * This is the category used by the DRM_DEBUG_ATOMIC() macro.
- *
- * VBL: used for verbose debug message in the vblank code
- * This is the category used by the DRM_DEBUG_VBL() 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=0x3f 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
