just something i threw together, not in final form, but it represents
tossing the legacy PM stuff. at the moment, the menuconfig entry for
PM_LEGACY lists it as "DEPRECATED", while the help screen calls it
"obsolete." that's a good sign that it's getting close to the time
for it to go, and the removal is fairly straightforward, but there's
no mention of its removal in the feature removal schedule file.
It's been like this for a long long time. I think you're right that it can
be
dropped, but I don't know the details (eg. why it hasn't been dropped yet).
One reason was that there are (were?) a number of machines which only powered
down properly using apm. It was discussed as part of shutting down after power
failure when your UPS is running out of power.
um ... what does APM have to do with legacy PM? two different issues,
no?
Since the patches are going into apm.c and apm was used for suspend and
poweroff before ACPI was a feature of the hardware, I assume there's a
relationship. As of 2.6.9 ACPI still couldn't power down one of my old
boxes, it hasn't been updated since that time, so I can't say what later
kernels will do.
