Detailed Description

struct ttm_bo_global - Buffer object driver global data.

: Pointer to a struct ttm_mem_global object for accounting. : Pointer to a dummy page used for mapping requests of unpopulated pages. : A shrink callback object used for buffer object swap. : Mutex protecting the device list. This mutex is held while traversing the device list for pm options. : Spinlock protecting the bo subsystem lru lists. : List of buffer object devices. : Lru list of buffer objects used for swapping.
