Resending in plain text mode I have been looking into adding Linux support for electronic privacy screens which is a feature on some new laptops which is built into the display and allows users to turn it on instead of needing to use a physical privacy filter. In discussions with my colleagues the idea of using either /sys/class/backlight or /sys/class/leds but this new feature does not seem to quite fit into either of those classes. I am proposing adding a class called "privacy_screen" to interface with these devices. The initial API would be simple just a single property called "privacy_state" which when set to 1 would mean that privacy is enabled and 0 when privacy is disabled. Current known use cases will use ACPI _DSM in order to interface with the privacy screens, but this class would allow device driver authors to use other interfaces as well. Example: # get privacy screen state cat /sys/class/privacy_screen/cros_privacy/privacy_state # 1: privacy enabled 0: privacy disabled # set privacy enabled echo 1 > /sys/class/privacy_screen/cros_privacy/privacy_state Does this approach seem to be reasonable? _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
