This is a proof-of-concept backend which acts like an EEPROM on the connected
|
|
|
|
|
I2C bus. The memory contents can be modified from userspace via this file
|
|
|
|
|
located in sysfs:

/sys/bus/i2c/devices/<device-directory>/slave-eeprom

As of 2015, Linux doesn't support poll on binary sysfs files, so there is no

|
|
|
notification when another master changed the content.
