I noticed last night (it may have started sooner) Intel is advertising
that something big is going to be announced on March 12th.
According to the hype, it will not only change the way you work but where you work.
Does anyone know what this is all about?
I hate it when they decide to rewrite the rules.
I think they invented a CPU that works in a portable computer.
They are very, very smart.

Kind of begs the question, How long until Centrino/Neutrino
combination?
Quite long I am afraid. Neutrino does not have any power-management
features, which is all Centrino is about. I think it will take QNX longer
than to support CD-R. And we don’t know yet how long the latter will take

Well supporting APM would be
whip up /dev/apm resource manager, polling APM events from BIOS
(supporting “cat /dev/apm/battery0” is useful on its own)
modify “shutdown” command to devctl("/dev/apm", DCMD_APM_SHUTDOWN)
sysmgr_reboot() should be called from APM resmgr.
modify DDK to register sleep/shutdown hooks when the
drivers want to be notified on APM events
1,2 could be done fairly easily.
The hard part is 3, which QSSL must take some kind of initiative
(or contracting customer who has $$$,manpower,and source code)
Actual needs for APM on embedded devices is an interesting topic.

Oh, maybe two weeks after they release the block device, scsi
pass-thru, CAM
DDK? Of course, we don’t know when that will be!
If you consider that my Newton and Agenda VR3 are both battery powered
embedded systems, I should think the requirement is obvious… Or
consider
battery powered field data loggers, if you don’t want to think of a PDA
as
an embedded system…

All their drivers also have to be modified to make use of those hooks. If
the power saving mode in question implies loss of runtime state information,
then drivers have to save their state and state of hardware, then restore it
upon wakeup.

Embedded devices are easier to deal with than general case (like PC) because
you have a predefined hardware environment. APM is obsolete though.
