In -current I added support for the additional I2C busses on piixpm(4) now I noticed that on my old AMD system the I2C bus seems to either connect all those 4 busses together (or there is a bug in the driver).
I would like to know if people with ATI SBx00 SMBus chips see the same effect as I do. Here the bit from my dmesg: piixpm0 at pci0 dev 20 function 0 "ATI SBx00 SMBus" rev 0x41: polling iic0 at piixpm0 sdtemp0 at iic0 addr 0x18: stts2002 sdtemp1 at iic0 addr 0x19: stts2002 sdtemp2 at iic0 addr 0x1a: stts2002 sdtemp3 at iic0 addr 0x1b: stts2002 spdmem0 at iic0 addr 0x50: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem1 at iic0 addr 0x51: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem2 at iic0 addr 0x52: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem3 at iic0 addr 0x53: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor iic1 at piixpm0 sdtemp4 at iic1 addr 0x18: stts2002 sdtemp5 at iic1 addr 0x19: stts2002 sdtemp6 at iic1 addr 0x1a: stts2002 sdtemp7 at iic1 addr 0x1b: stts2002 spdmem4 at iic1 addr 0x50: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem5 at iic1 addr 0x51: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem6 at iic1 addr 0x52: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem7 at iic1 addr 0x53: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor iic2 at piixpm0 sdtemp8 at iic2 addr 0x18: stts2002 sdtemp9 at iic2 addr 0x19: stts2002 sdtemp10 at iic2 addr 0x1a: stts2002 sdtemp11 at iic2 addr 0x1b: stts2002 spdmem8 at iic2 addr 0x50: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem9 at iic2 addr 0x51: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem10 at iic2 addr 0x52: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem11 at iic2 addr 0x53: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor iic3 at piixpm0 sdtemp12 at iic3 addr 0x18: stts2002 sdtemp13 at iic3 addr 0x19: stts2002 sdtemp14 at iic3 addr 0x1a: stts2002 sdtemp15 at iic3 addr 0x1b: stts2002 spdmem12 at iic3 addr 0x50: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem13 at iic3 addr 0x51: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem14 at iic3 addr 0x52: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor spdmem15 at iic3 addr 0x53: 4GB DDR3 SDRAM ECC PC3-10600 with thermal sensor -- :wq Claudio
