to work with ipmitools. It works with other tools that have an OpenIPMI
driver interface. The port will need to get updated to used this.
I have not implemented the IPMB mode yet so ioctl's for that don't
really do much otherwise it should work like the OpenIPMI version.
The ipmi.h definitions was derived from the ipmitool header file.
The bus attachments are done for smbios and pci/smbios. Differences
in bus probe order for modules/static are delt with. ACPI attachment
should be done.
This drivers registers with the watchdod(4) interface
Work to do:
- BT interface
- IPMB mode
This has been tested on Dell PE2850, PE2650 & PE850 with i386 & amd64
kernel.
I will link this into the build on next week.
Tom Rhodes, helped me with the man page.
