The SMBus Driver

----------------



The SMBus driver allows up to 4 SMBus devices to be configured in the

system.  By default, the driver will register any SMBus interfaces it finds

in the I2C address range of 0x20 to 0x4f on any adapter.  You can change this

at module load time (for a module) with:



  modprobe ipmi_smb.o

	addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]

	dbg=<flags1>,<flags2>...

	[defaultprobe=1] [dbg_probe=1]



The addresses are specified in pairs, the first is the adapter ID and the

second is the I2C address on that adapter.



The debug flags are bit flags for each BMC found, they are:

IPMI messages: 1, driver state: 2, timing: 4, I2C probe: 8



Setting smb_defaultprobe to zero disabled the default probing of SMBus

interfaces at address range 0x20 to 0x4f.  This means that only the

BMCs specified on the smb_addr line will be detected.



Setting smb_dbg_probe to 1 will enable debugging of the probing and

detection process for BMCs on the SMBusses.



Discovering the IPMI compliant BMC on the SMBus can cause devices

on the I2C bus to fail. The SMBus driver writes a "Get Device ID" IPMI

message as a block write to the I2C bus and waits for a response.

This action can be detrimental to some I2C devices. It is highly recommended

that the known I2c address be given to the SMBus driver in the smb_addr

parameter. The default address range will not be used when a smb_addr

parameter is provided.



When compiled into the kernel, the addresses can be specified on the

kernel command line as:



  ipmb_smb.addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]

	ipmi_smb.dbg=<flags1>,<flags2>...

	ipmi_smb.defaultprobe=0 ipmi_smb.dbg_probe=1



These are the same options as on the module command line.



Note that you might need some I2C changes if CONFIG_IPMI_PANIC_EVENT

is enabled along with this, so the I2C driver knows to run to

completion during sending a panic event.
