Keep next_process, connection, etc. in ProcessManager instead
of SteamOSManager.
Also change exit_code to only give the exit code if known.
Added wait to do the wait and get the proper
exit code on completion.
Also added libc::pid_t use in process.rs.
In order to be able to pause/resume/cancel some operations
that could take some time we need to keep track of those processes
and give callers an id to pause/resume/cancel them with later.
In these long running cases, return an object path that can be used
to pause/resume/cancel when told to.
TODO:
- Add some tests and manually test that the right things happen
Instead of always using /sys/class/drm/card0 based paths, use
/sys/class/hwmon looking for amdgpu name file to determine where
to look.
Fixes reading TDPLimit, GPUPerformanceLevel and ManualGPUClock
in cases where sysfs uses card1 or other paths.
NOTE: Using wrong cardX path is a bug and will be fixed, but
this makes steamos-manager a bit more resilient to those bugs.
This change implements the ability to get and set the WiFi back-end,
by leveraging a new script created for that purpose.
The idea is to be able to use 'wpa_supplicant' (which is the default
back-end in NetworkManager upstream) when 'iwd' (the default in
SteamOS) does not work for some reason.
This change interacts with another feature of steamos-manager, which
is to set debug mode for WiFi. Handling debug mode complicates things
substantially because those methods write config for 'iwd' and restart
the daemons/systemd units, with many interdependencies.
Instead of trying to implement all at once and attempt feature-parity
between back-ends on this aspect from the start, as a first step the
operations are just declared incompatible. As a result, if
WifiDebugMode=on the back-end cannot be changed, and conversely the
WifiDebugMode cannot be turned on when the back-end is
'wpa_supplicant'.
