I'm the maintainer of the IPMI driver, and there is a new function that needs to be added that does IPMI over SMBUS. This requires some minor changes to the I2C interface to support a special function of the IPMI driver. The IPMI driver support the ability to store panic information into the Systen Event Log (SEL) of the IPMI controller. Since it does this at panic time, the system can no longer schedule. Thus the driver has to be able to do this without jiffies or scheduling. There are also some watchdog operations that need to happen at panic time that also need this. I've attached a patch that modifies the I2C bus drivers to add the capability to use a delay. There's some more work to do on the IPMI driver portion, still, but I thought I would socialize this with the sensors group first. This is just a first shot, I'm sure I've missed something. This is relative to 2.6.11-rc1. Thanks, -Corey -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
