Jean Delvare <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #5 from Jean Delvare <[email protected]> 2011-01-11 12:44:56 --- Thanks for the pointer to the outdated documentation. I didn't remember we had this, I'll clean it up. That being said, I still don't understand why i2c_ec was removed in the first place. Just because the sbs driver no longer needs it, doesn't mean it wasn't useful. i2c_ec could be used to access the SMBus on some systems where this is currently not possible due to the resource conflict that prevents native drivers from being used. The SMBus doesn't only host SBS, it also typically hosts SPD EEPROMs on memory modules and sometimes hardware monitoring ASICs. As a matter of fact, we already have one driver for one of the possible ACPI implementations of SMBus: see drivers/i2c/busses/i2c-scmi.c. I'm not sure why different implementations were specified by ACPI, but as far as I can see i2c_ec.c was for a completely different implementation. So I would like to see i2c_ec.c revived as drivers/i2c/buses/i2c-acpiec.c, for systems which need it. Len, any objection? That being said, there is no proof so far that the reporter's system would be supported by the old i2c_ec driver. Please check if "ACPI0001" (or "SMBUS01") appears anywhere in your disassembled DSDT. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
