So @btashton you want the userspace provide a buffer/FIFO to driver and avoid the memory copy? 1. Sensor normally connect through the external bus(I2C, SPI, UART) and never tightly couple with SoC, so I expect the special memory buffer management like GPU/Display/Video isn't required and memory can be always allocated inside kernel. 2. We can expose the internal buffer and queue offset to userspace like what fb or alsa driver done. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
