Hi Joshua, There is some low level support in NetBSD for trim in the device drivers (wd for example), but there is no ioctl interface, filesystem support and of course no userland trim utility. I would check out how FreeBSD does it first and model it after that. I would start with ioctl support, then userland utility support to test and finally I would start adding support to ffs. I think that we would need to update our zfs code to support trim. Best, christos
