BMS 칩셋 i2c 주소를 어떻게 접근하나 찾는중
i2cdetect를 통해서는 이상한것만 보이는데..
gmbus는 그래픽 카드쪽이라고 검색은 나오지만.. 확실한건 좀더 봐야 할 듯 하고

$ i2cdetect -l
i2c-3 unknown i915 gmbus dpc N/A
i2c-1 unknown i915 gmbus vga N/A
i2c-6 unknown DPDDC-B N/A
i2c-4 unknown i915 gmbus dpb N/A
i2c-2 unknown i915 gmbus panel N/A
i2c-0 unknown i915 gmbus ssc N/A
i2c-5 unknown i915 gmbus dpd N/A

acpi 명령을 통해 보면 배터리 상태나 온도등이 그냥 나오네.. 버스가 다른가?
