2005-07-29[PATCH] I2C: 24RF08 corruption prevention (again)Jean Delvare2-6/+10
The 24RF08 corruption prevention in the eeprom and max6875 drivers wasn't complete. For one thing, the additional quick write should happen as soon as possible and unconditionally, while both drivers had error paths before. For another, when a given chip is forced, the core does not emit a quick write, so a second quick write would cause the corruption rather than prevent it. I plan to move the corruption prevention in the core in the long run, so that individual drivers don't have to care anymore. But I need to merge i2c_probe and i2c_detect before I do (work in progress).

2005-07-11[PATCH] I2C: New max6875 driver may corrupt EEPROMsJean Delvare1-1/+5
After a careful code analysis on the new max6875 driver (drivers/i2c/chips/max6875.c), I have come to the conclusion that this driver may cause EEPROM corruptions if used on random systems. The EEPROM part of the MAX6875 chip is accessed using rather uncommon I2C sequences. What is seen by the MAX6875 as reads can be seen by a standard EEPROM (24C02) as writes. If you check the detection method used by the driver, you'll find that the first SMBus command it will send on the bus is i2c_smbus_write_byte_data(client, 0x80, 0x40). For the MAX6875 it makes an internal pointer point to a specific offset of the EEPROM waiting for a subsequent read command, so it's not an actual data write operation, but for a standard EEPROM, this instead means writing value 0x40 to offset 0x80. Blame Philips and Intel for the obscure protocol. Since the MAX6875 and the standard, common 24C02 EEPROMs share two I2C addresses (0x50 and 0x52), loading the max6875 driver on a system with standard EEPROMs at either address will trigger a write on these EEPROMs, which will lead to their corruption if they happen not to be write protected. This kind of EEPROMs can be found on memory modules (SPD), ethernet adapters (MAC address), laptops (proprietary data) and displays (EDID/DDC). Most of these are hopefully write-protected, but not all of them. For this reason, I would recommend that the max6875 driver be neutralized, in a way that nobody can corrupt his/her EEPROMs by just loading the driver. This means either deleting the driver completely, or not listing any default address for it. I'd like this to be done before 2.6.13-rc1 is released. Additionally, the max6875 driver lacks the 24RF08 corruption preventer present in the eeprom driver, which means that loading this driver in a system with such a chip would corrupt it as well. Here is a proposed quick patch addressing the issue, although I wouldn't mind a complete removal if it makes everyone feel safer. I think Ben has plans to replace this driver by a much simplified one anyway. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

I am using the atxp1 module to change vcore on my NForce2 via userspace daemon (see punnoor.de). Currently the atxp1 module will write to the log on every vcore change, thus filling up my log - which I don't want.
