Hello, I wrote SMBus controller driver for Intel PIIX4 Power Management Controller, and I don't know how to test the driver. I think smb(4) is generic "upstream" driver for SMBus, but I don't know how to recognize and how to use it.Opening /dev/smb0 (device node made) only results EINVAL. Currently I test code in PCI probe routine by issuing recieve method from smbus address 0xa0-0xa6(assigned for DIMM EEPROM ) and 0x58-0x5e(assigned for Hectra * hardware sensor) . In my side, 0xa0,0xa2,0xa4 Succeed and others Failed, this matches the machine configuration. (It holds 768MB DRAM(256M DIMMx3) and no hardware sensor.) any Ideas? My code is at http://www.planet.kobe-u.ac.jp/~takawata/intiic.c http://www.planet.kobe-u.ac.jp/~takawata/intiicreg.h and to use it, you will need changes in smbus.c conf/files.???? configuration file. and so on.
