    Implementation of TARGET_MODE applications
    How we used TARGET_MODE in the kernel to create and interesting product

    This presentation will cover a real world implementation of the TARGET_MODE infrastructure in the kernel (stable/6). Topics to include: drivers used (isp, aic7xxx, firewire). scsi_target userland code vs kernel drivers missing drivers (4/8G isp support, iSCSI target)

    Target Mode describes a feature within certain drivers that allows a FreeBSD system to emulate a Target in the SCSI sense of the word. By recompiling your kernel with this feature enabled, it permits one to turn a FreeBSD system into an external hard disk. This feature of the FreeBSD kernel provides many interesting implementations and is highly desirable to many organizations whom run FreeBSD as their platform.

    I have been tasked with the maintenance of a proprietary target driver that interfaces with the FreeBSD kernel to do offsite data mirroring at the block level. This talk will discuss the implementation of that kernel mode driver and the process my employer went through to implement a robust and flexible appliance.

    Since I took over the implementation, we have implemented U160 SCSI(via aic7xxx), 2G Fibre Channel(via isp) and Firewire 400 (via sbp_targ). Each driver has it's own subtleties and requirements. I personally enhanced the existing Firewire target driver and was able to get some interesting results.

    I hope to demonstrate a functional Firewire 400/800 target and show how useful this application can be for the embedded space. Also, I wish to demonstrate the need for iSCSI. USB and 4/8G Fibre Channel target implementations that use the TARGET_MODE infrastructure that is currently in place to allow others to expand their various interface types.

    The presentation should consist of a high level overview, followed by detailed implementation instructions with regards to the Firewire implementation and finish up with a hands-on demonstration with a FreeBSD PC flipped into TARGET_MODE and a Mac.

    Firewire BoF Plugfest
    Debugging and testing of Firewire products with FreeBSD

    Come one come all to a Firewire plugfest. Let's debug and test together and see if we can't knock out some features and bugs.

    A hands-on testing and debugging session of the Firewire stack in FreeBSD.

    Everyone who wishes to attend should bring their Firewire devices, ext Drives and Cameras, and their Laptops. I will be debugging and capturing data points to enhance and improve features in the Firewire stack.

    We should be able to knock out quite a bunch of bugs if folks can bring their various Firewire devices along with their various PCs.

    Even if your Firewire device works perfectly, bring it by so it can be documented as supported by the Firewire team!
