LKML: Paul Cercueil: [PATCH v3 04/11] iio: buffer-dma: Enable buffer …

WebThis block reads data from the direct-memory-access (DMA) buffer of the specified AXI4-Stream IP core device by using the Industrial I/O (IIO) library drivers. The AXI4-Stream IIO Read block enables you to achieve a low-latency, high-throughput data transmission between your model deployed on the processor and the IP core on the FPGA. WebImplement the two functions iio_dma_buffer_alloc_dmabuf() and iio_dma_buffer_enqueue_dmabuf(), as well as all the necessary bits to enable userspace access to the DMABUF objects. These two functions are exported as GPL symbols so that IIO buffer implementations can support the new DMABUF based userspace API.
