__vb2_queue_alloc 分配vivi_buffer结构体的空间(缓存区头部信息), 如果使用的是V4L2_MEMORY_MMAP类型则 调用==>__vb2_buf_mem_alloc ==> q->mem_ops->alloc 即vb2_vmalloc_alloc 分配空间,将分配的空间指向vb2_buffer->planes[0].mem_priv ,该指针保存着分配到的空间,该指针指向vb2_vmalloc_buf结构体 ...
this patch drops setting of vb2 buffer state to VB2_BUF_STATE_ACTIVE, as any buffer queued to the driver is marked ACTIVE by the vb2 core.
