so the ipmi_smb driver Corey just posted to LKML, together with his previous i2c patches, together with http://bmcsensors-26.sourceforge.net , and you should be able to get sensor data from the 87431! let us know how it works! p.s. Corey I looked through ipmi_smb and it looks good. this should give smbus block transfers and PEC quite a good testing. mds Chan Min Wai wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > However There is still one things is missing... > > Driver for the "IPMI" Device in kernel... > Without that there is no way for us to even touch the ipmi chip in the > board. > > Regards, > Chan Min Wai > > Ilia Stolov wrote: > >>The Host interface of PC87431 is IPMI 1.5/2.0 SSIF - the new host >>interface introduced in IPMI 2.0 spec.
