[Arm-dev] Gigabyte MP30-AR0

I am following up on this.



You need to use freeipmi for inband. Ipmitools is for out-of-band only.



+ Update kernel to 4.2.0-0.26.el1

$ yum install i2-tools

$ yum install freeipimi

$ insmod i2c-dev

$ i2cdetect –l

i2c-0   smbus           MAILBOX I2C                             SMBus
adapter  << Use this one with freeipmi

i2c-1   i2c                 AST i2c bit bus                         I2C
adapter



# Get BMC info

bmc-info --no-probing --driver-type=SSIF --driver-address=0x10
--driver-device=/dev/i2c-0 --get-device-id –debug



# Get BMC config (mainly for its IP address)

$ bmc-config --driver-type=SSIF --driver-address=0x10
--driver-device=/dev/i2c-0 -o -S Lan_Conf



user at localhost:~$ ipmitool -I lanplus -H <BMC IP address>  -U admin -P
password fru print

user at localhost:~$ ipmitool -I lanplus -H <BMC IP address>  -U admin -P
password sdr list

user at localhost:~$ ipmitool -I lanplus -H <BMC IP address>  -U admin -P
password sensor list



etc.

Hi folks,



X-Gene kernel does not support ipmitools, which relies on OpenIPMI driver
(using /dev/ipmi).

Instead, communications to the BMC is via  SSIF over /dev/i2c.



You can either use ipmitools with the BMC LAN interface directly (out of
band), or freeipmi (inband).

I don’t have the information handy at this time – will follow up tomorrow.

Does anyone have any input on what (if any) lm_sensors drivers can be

something other than ipmi available?

You'll probably find it's the default kernel causing the crash, it'll
likely work with your new kernel, it does here.


No, still causes a crash:
Do you want to scan for Super I/O sensors? (YES/no):

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no):

So it seems the sensors aren't there, and proving the various I/O
ranges causes a crash.

Still it would be nice to get "ipmitool sensor" working locally.
# ipmitool sensor
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0:
No such file or directory
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0:

Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0:
No such file or directory

Unable to open SDR for reading

Is there a driver that I missed?

This may be a compatibility issue with ipmitools package, the protocol
is clearly compatible though. I guess you can't load the ipmi_si module?
I created /dev/ipmi0 manually but it made no difference to the error
displayed.



# modprobe ipmi_si
modprobe: ERROR: could not insert 'ipmi_si': No such device

So I'm wondering if a different driver is needed. Or a patch for this one.

Having gone into the scant manual and the Ubuntu image (along with some
Googling) it seems the board requires an SSIF driver (ipmi_smb?) which is
not in mainline since 2.6 days.
