aw_sid
—
driver for the SID controller in Allwinner SoC
The aw_sid
device driver provides support for the
Allwinner SID (Security ID) controller. This controller provides root security
keys that may be used as either a device unique ID or to generate a MAC
address.
The aw_sid
driver supports the SID controller with one
of the following compatible strings:
- allwinner,sun4i-a10-sid
- allwinner,sun7i-a20-sid
- allwinner,sun50i-a64-sid
- allwinner,sun8i-a83t-sid
- allwinner,sun8i-h3-sid
The following read-only variables are available via
sysctl(8):
- dev.aw_sid.rootkey
- Root security key for this device.
The aw_sid
device driver first appeared in
FreeBSD 11.0.
