Subject: New feature: a "poweroff" command
Date: Wed, 25 May 2016 21:51:16 -0400 [thread overview]
Message-ID: <b9258ff8-c7ee-2e05-e5f4-f9456721a9cb@jodybruchon.com> (raw)
I have just committed a 'poweroff' command to ELKS. Piggybacking on the
existing sys_reboot() syscall, the commit uses Advanced Power Management
(APM) BIOS calls to power down the computer when the poweroff command is
issued. If you're running in an emulator like QEMU, Bochs, or
Virtualbox, or if you're running ELKS on any APM-enabled platform such
as most 486 or higher laptops and any older ATX PC, this is a much more
convenient way to shut down.
I find this to be a nicer way of exiting the QEMU curses interface than
ESC, 2, q, [enter] in any case, and most ELKS testing seems to be done
on more modern systems and emulators, so it makes sense. I would like
someone to test it on a non-APM system to make sure that a failure due
to no APM support falls through to an error message.
Also, I am thinking of renaming sys_reboot() to sys_shutdown() to better
reflect its actual purpose. Any objections?
