Hi Y'll
Several of you ask, so here is a generic answer;
I am actively working on i2o subsystem for FreeBSD. The reference card
for this work is the DPT 5th Generation controllers.
Status: Much of the work, particularly IRT DPT controllers is
complete.
All the mechanics and kernel modifications to allow
recognition of i2o card and in particular DPT cards
is in place. I am able, routinely to:
* Detect the cards
* Negotiate setup and configuration
* Initialize the IOP
* Build a list of all devices known
* Query device attributes and capabilities
* Notify the kernel of known devices
* Accept block I/O requests, send to the IOP, return results.
* Accept character (raw) device I/O requests, translate to
Block I/O requests, process and reply.
* Still to be done: * Complete debugging disklabel code.
* Add fdisk slice code
* Mature and stabilize error handling
* Complete port of dptutil (RAID
management.
Most Helpful Help: Fdisk Slice, disklabel, and devfs
code completion.
Personal Note; I am so swamped with work that I have little
time, if any, for participation in mailing
list activities. This is NOT to say that I am
not active in FreeBSD, or the i2o project. If
you need me, or like to chat, drop me a line!
