57 * GPU mapping life cycle
58 * ======================
59 *
60 * Kernel mappings
61 * ---------------
62 *
63 * Kernel mappings are created through vm.map(..., false):
64 *
65 * - Mappings to the same allocations are reused and refcounted.
66 * - This path does not support deferred unmapping (i.e. kernel must wait for
67 * all hw operations on the buffer to complete before unmapping).
68 * - References to dmabuf are owned and managed by the (kernel) clients of
69 * the gk20a_vm layer.
70 *
71 *
72 * User space mappings
73 * -------------------
74 *
75 * User space mappings are created through as.map_buffer -> vm.map(..., true):
76 *
77 * - Mappings to the same allocations are reused and refcounted.
78 * - This path supports deferred unmapping (i.e. we delay the actual unmapping
79 * until all hw operations have completed).
80 * - References to dmabuf are owned and managed by the vm_gk20a
81 * layer itself. vm.map acquires these refs, and sets
82 * mapped_buffer->own_mem_ref to record that we must release the refs when we
83 * actually unmap.
