On a NUMA system the eeprom interface in /sys
/sys/bus/i2c/drivers/eeprom/*
do not list all the DRAM eeproms. Only the DRAM from one node is listed. I have a 4 socket system with all 16 banks filled and see only 4 entries.
My suspicion (without looking at any code) is that the list of i2c devices with eeproms is collected once and this happens only on one CPU. I sees not to be dynamic since when I read the files with taskset restricting execution on certain sockets and cores the result doesn't change.
Is this known or expected (I hope not the latter)? Where should I look at? I assume that's in the i2c code?
