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.
