I've created an illumos upower backend, which seems to work on several
notebooks where I've tested it.
The code itself lives in oi-userland repository:
https://github.com/OpenIndiana/oi-userland/pull/3869 (I point to the PR
with upower integration, as it has some history).
UPower illumos backend is based on OpenBSD backend. It supports systems
with one battery and one AC device (or without them :)).
UPower daemon is supposed to start at boot as separate service, as we
don't support services, automatically activated by dbus requests.
There are several patches:
- this adds check if ld supports '--as-needed' option
- We have rather ancient version of ConsoleKit and this one is intended
to map 'logind-style' ConsoleKit interfaces to older interfaces (I have
no intention to upstream it)
- this patch allowed us to avoid crashes of upower client and
mate-power-manager when upower service was turned off - client
applications expect to get list of devices and don't handle NULL properly.
The main patch:
The most methods are wrappers around minor_device_ioctl() function,
which looks for acpi_drv device of necessary kind and fires requested
IOCTL on it. We currently look only on first found device of kind "ac"
and "battery". Luckily, this covers most of notebooks.
I'm interested in getting some reviews and upstreaming it.
