Now all the DRM debug info will be reported if the boot option of "drm.debug=1" is added. Sometimes it is inconvenient to get the debug info in KMS mode. We will get too much unrelated info. This will separate several DRM debug levels and the debug level can be used to print the different debug info. And the debug level is controlled by the module parameter of drm.debug In this patch it is divided into four debug levels; drm_core, drm_driver, drm_kms, drm_mode. At the same time we can get the different debug info by changing the debug level. This can be done by adding the module parameter. Of course it can be changed through the /sys/module/drm/parameters/debug after the system is booted. Four debug macro definitions are provided. DRM_DEBUG(fmt, args...) DRM_DEBUG_DRIVER(prefix, fmt, args...) DRM_DEBUG_KMS(prefix, fmt, args...) DRM_DEBUG_MODE(prefix, fmt, args...) When the boot option of "drm.debug=4" is added, it will print the debug info using DRM_DEBUG_KMS macro definition. When the boot option of "drm.debug=6" is added, it will print the debug info using DRM_DEBUG_KMS/DRM_DEBUG_DRIVER. Sometimes we expect to print the value of an array. For example: SDVO command, In such case the following four DRM debug macro definitions are added: DRM_LOG(fmt, args...) DRM_LOG_DRIVER(fmt, args...) DRM_LOG_KMS(fmt, args...) DRM_LOG_MODE(fmt, args...) Signed-off-by: -

A driver will use the _DRM_DRIVER map flag to indicate that it wants to be responsible for removing the map itself, bypassing the DRM's automagic cleanup code. Since the multi-master changes this has been broken, resulting in some drivers having their registers unmapped before it's finished with them. Signed-off-by:

By sending a broken execbuffer (its length was not suitably aligned) I triggered an operation upon a freed object. The invalid alignment was discovered after updating the write_domain on the object but before the object was placed on the active queue. So during the unwind process following the error, the now freed object attempts to flush its non-existent, but outstanding, GPU writes causing this use-after-free.
