RE: [Freeipmi-devel] 64-bit issues with OpenIPMI driver on FreeBSD-7.2

[Andy Cress]

FYI.  Shortly after this email, I did get this issue resolved in 
ipmiutil-2.5.2. 
After the pragma_pack, I also had to change the IOCTL definitions, since they 
are slightly different between Linux and FreeBSD.

Mark,

There is definitely an interface incompatibility between the FreeBSD ipmi 
driver and the Linux OpenIPMI driver.  The same code to talk to /dev/ipmi0 on 
Linux does not work on FreeBSD (either 32-bit or 64-bit).  I haven't diagnosed 
why exactly, but the ipmi_req size is a start.  If we had a solution, it could 
be implemented with #ifdef's.  It's on my TODO list, but keeps getting bumped 
by more urgent issues.

I believe that both FreeIPMI and ipmiutil use the direct I/O approach instead 
for FreeBSD.
Does anyone know of any code that DOES work with the FreeBSD /dev/ipmi0 
interface?

Andy

Hi Mark,

I don't personally have experience w/ the OpenIPMI driver on FreeBSD.
As an FYI, you may want to try the OpenIPMI mailing list too to see if anyone 
else there has experience w/ the driver on FreeBSD.
