Detailed Description

struct ttm_bo_device - Buffer object driver device-specific data.

: Pointer to a struct ttm_bo_driver struct setup by the driver. : An array of mem_type_managers. : Protects the synchronizing members on all bos belonging to this device. : Range manager for the device address space. lru_lock: Spinlock that protects the buffer+device lru lists and ddestroy lists. : Current validation sequence. : Try nicely to wait for buffer idle when cleaning a manager. If a GPU lockup has been detected, this is forced to 0. : A pointer to the struct address_space representing the device address space. : Work queue structure for the delayed delete workqueue.
