In pci_epf_test_init_dma_chan() epf_test->dma_chan_rx is assigned from dma_request_channel() with DMA_DEV_TO_MEM as filter.dma_mask. However, in pci_epf_test_data_transfer() if the dir is DMA_DEV_TO_MEM, epf->dma_chan_rx should be used but instead we are using epf_test->...
如下图,i2c驱动分为如下几个重要模块 核心层core,完成i2c总线、设备、驱动模型,对用户提供sys文件系统访问支持;为i2c内部adpter等提供注册接口。 adpter,适配器,实际就是CPU集成的IIC控制器,有cpu控制,完成i2c物理总线操作,busses文件夹里,有各个cpu adapter的具体实现;algorithm集成到这个模块里,而且是adapter的一部分...
