Asrock Rack E3C226D2I #308

Open tapochkin opened 4 years ago

Hi. Please point me to the right place to ask my questions in case it's offtopic here.

My system is built on Asrock Rack E3C226D2I/Intel Xeon E3-1240L v3. The output of intelmetool is confusing:

# sudo ./intelmetool -m ... MEI found: [8086:8c3a] 8 Series/C220 Series Chipset Family MEI Controller #1

ME Status : 0x1e0f0345 ME Status 2 : 0xb800a100

ME: FW Partition Table : OK ME: Bringup Loader Failure : NO ME: Firmware Init Complete : YES ME: Manufacturing Mode : NO ME: Boot Options Present : NO ME: Update In Progress : NO ME: Current Working State : Normal ME: Current Operation State : M0 without UMA ME: Current Operation Mode : (null) ME: Error Code : No Error ME: Progress Phase : Global reset after an error ME: Power Management Event : Sx/M3->S0/M0 ME: Progress Phase State : Unknown 0x00

ME: Extend Register not valid

ME: timeout waiting for data: expected 8, available 6 ME: GET FW VERSION message failed`

iomem=relaxed option has no impact on the intelmetool output.

There is also no /dev/mei0 device:

# ls /dev/mei ls: cannot access '/dev/mei': No such file or directory

The only ME related BIOS setting states SPS version and ME FW State (SPS ME FW Active).

So is IME functional or not? Do I still need to apply the me_cleaner?
