I have just improved the support for software powerdown in the NetBSD
kernel somewhat. Previously, if you had APM on an i386, RB_HALT would
cause the machine to power down. These semantics are undesirable on
systems which support software powerdown _and_ have a Real console monitor
(e.g. Sun4m, Digital Personal Workstation, etc.).
Now, to power down, RB_POWERDOWN must be specified. RB_POWERDOWN implies
RB_HALT, so if the platform does not support software powerdown, or if the
powerdown fails, the system will simply halt.
A -p option has been added to both halt(8) and shutdown(8) to specifiy
that software powerdown is to be performed.
- alpha: Digital Personal Workstation (Miata) can now software
- i386: Systems w/ APM (mostly laptops) will no longer powerdown
on halt unless -p is specified to halt(8) or shutdown(8).
- sparc: Sun4m systems which support software powerdown can
now do so.
If you have any problems, please send a bug report w/ send-pr(1).
