设置USB请求的actual、status、direction、epnum和length等字段,对于输出端点,length必须是MaxPacketSize的整数倍。 对USB请求的缓冲区进行流式DMA映射。USB请求缓冲区是Function驱动使用kmalloc等函数分配,DMA不能直接使用,需要进行DMA映射,具体的映射过程在2.7小结介绍。 将提交的USB请求先放到pending_list链表。 调用__...

在__memblock_remove()中有提到,memblock_isolate_range()主要作用是将要移除的物理内存区从reserved 内存区中分离出来,将 start_rgn 和 end_rgn(该内存区块的起始、结束索引号)返回回去,而这里,由于我们传入的type 是 memblock.memory,该函数会根据入参 base 和 size 标记节点内存范围,将该内存从 memory 中划分...
