Hi, nice to see someone else interested in the I2C & DMA topic.
Please check this series which I sent out recently: "[RFC PATCH v4 0/6] i2c: document DMA handling and add helpers for it" In that series, I proposed... > 3. kmalloc data buffer instead of local variables buf in function > i2c_smbus_xfer_emulated(...) ... this solution. Although I have to check Mauro's general response to the series first. I'd be interested in what you think of the series, too. Kind regards, Wolfram
