/*
* 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

*
* Drivers provide a hardware-specific implementation of how transactions
* are executed via the .transfer() function. A pointer to a drm_dp_aux_msg
* structure describing the transaction is passed into this function. Upon
* success, the implementation should return the number of payload bytes
* that were transferred, or a negative error-code on failure. Helpers
* propagate errors from the .transfer() function, with the exception of
* the -EBUSY error, which causes a transaction to be retried. On a short,
* helpers will return -EPROTO to make it simpler to check for failure.
*
* An AUX channel can also be used to transport I2C messages to a sink. A
* typical application of that is to access an EDID that's present in the
* sink device. The .transfer() function can also be used to execute such
* transactions. The drm_dp_aux_register_i2c_bus() function registers an
* I2C adapter that can be passed to drm_probe_ddc(). Upon removal, drivers
* should call drm_dp_aux_unregister_i2c_bus() to remove the I2C adapter.
*
* Note that the aux helper code assumes that the .transfer() function
* only modifies the reply field of the drm_dp_aux_msg structure. The
* retry logic and i2c helpers assume this is the case.
