I have just committed a number of CAM changes that will require recompilation of any userland programs you have that access the CAM passthrough driver. So things like cdrecord, xmcd, etc., should be recompiled.
The best way to update your system is via make world. NOTE: I would really like to hear from NCR owners about these changes. Justin and I made a small negotiation change in the NCR driver that should mean that people with 875's and the like should get Ultra speeds without putting options in their kernel. To summarize, these changes: - add new 'tags' and 'negotiate' commands to camcontrol. The tags command allows setting and viewing the number of tagged openings, and the negotiate command allows viewing and setting negotiation parameters for devices. - add code to make the transport layer's sink devices invisible to camcontrol devlist by default. (they reappear with -v) - The CD and DA drivers now attach regardless of what errors they get back from a read capacity. (with one exception -- "logical unit not supported") - Fixed a negotiation bug in the NCR driver. Note that the ahc, adv, and ncr drivers are the only drivers that fully support the 'camcontrol negotiate' command at this point. Other drivers, like the adw driver, may let you turn sync negotiation on and off but won't let you set the sync rate. In the case of the adw boards, I think it's a hardware limitation. Other drivers, like the bt driver, don't support the XPT_SET_TRAN_SETTINGS CCB at all, so you can't set any negotiation parameters. The 'tags' command should work on any device, because tagged queueing is handled by the transport layer, and not individual peripheral drivers. I plan on checking all of this code into -stable as well, hopefully later on today. Many thanks to Justin for helping with these changes and reviewing everything.
