Jonas Ådahl	ce5a5789bb	native: Release output device files that are unused ... In order to make it possible to e.g. unload an unused DRM device, we need to make sure that we don't keep the file descriptor open if we don't need it; otherwise we block anyone from unloading the corresponding module.

Jonas Ådahl	5502f956f5	device-file: Add tags ... Tags are meant to make it possible for a device file opener to tag a file if it has affected the state the file descriptor is in; e.g. if it has enabled a DRM capability.

Jonas Ådahl	b4cf839e87	device-pool: Add way to open files read-only ... Will be used by libinput's tablet device led device files. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1828>	2021-07-07 21:03:25 +02:00
Jonas Ådahl	ee8c252a8c	native: Add device pool for tracking device file descriptors ... This practically does the same thing as part of MetaLauncher, except with added thread safety and caching. For example, opening the same file a second time will return the same MetaDeviceFile, and only once all acquired MetaDeviceFile's are released, will the file descriptor be closed and control of the device released.
