I have a code that write data to a I2C-EEPROM. The i2c-driver is config to use DMA. But is there anyway I can check that data is transfered by i2c using DMA from my program in user-space?
Thanks!

Roughly you may check the interrupt counter of DMA controller (if it's a separate device). Otherwise it's hardly to achieve. And usually i2c buses (their drivers) are not using DMA at all. – 0andriy Jun 29 '16 at 22:57

Oh! good suggestion. You are right, I can check it there. Many thanks! – dvn0zzz Jul 01 '16 at 03:16
