Hello,
Adding Corey in cc: . I guess I should have done that in the first place.
Yes, probably so. I've been travelling and didn't see it on the mailing
lists until now.
There is already a BT driver in the kernel, in drivers/char/ipmi, why
won't that work?
The new driver is the host side (running on the BMC), the existing one
is the client (running on the PC).

Ok, that's not really clear from the documentation or the Kconfig.
In the IPMI spec the "host" side is the computer side, not the BMC
side. Like:
11.6.1 BT Host Interface Registers
The Host BT interface provides an independent set of registers and
interrupts to allow the Host driver to
communicate with the baseboard management controller without
conflicting with the O/S ACPI driver.
In light of that, this should probably be named the bt-bmc driver.
I haven't reviewed this in detail, but I'm ok with putting it in
drivers/char/ipmi. The state machine part looks reasonably
generic. The configuration part isn't, but that could be split
out later if necessary.
what do you mean by configuration ? I am ready to send a v2. May be
I can add a few other things.
The part that sets everything up, basically everything from
bt_host_fops down.
If you were to use this on another system, that code would have to be
made more generic and the machine-specific part split into different
files, but that's not necessary now, I don't think.
