  • disable command queuing at startup?

    From Winston@21:1/5 to All on Fri Aug 23 12:55:56 2024
    Once FreeBSD is up and running,
    "camcontrol negotiate $device -T disable"
    will disable command queuing for $device.

    Is there a setting or hint.* in some .conf file (loader.conf.local?)
    that would do that during startup?

    Thanks!

    [I didn't spot an answer in camcontrol(8), ada(4), ahci(4), cam(3),
    cam(4), driver(9), device(9), devclass(9), device.hints(5), or
    sysctl(8), but maybe I missed it.]

    rc.local perhaps?

    That would at least ensure it happens. It'd be even better if
    there were some way for "Command Queueing enabled" during device
    discovery to be suppressed for that device, especially if it could be
    done based on manufacturer or model rather than $device.
