Hi All, Here is the privacy-screen related code which we discussed a while ago. This series consists of a number of different parts: 1. A new version of Rajat's privacy-screen connector properties patch, this adds new userspace API in the form of new properties 2. Since on most devices the privacy screen is actually controlled by some vendor specific ACPI/WMI interface which has a driver under drivers/platform/x86, we need some "glue" code to make this functionality available to KMS drivers. Patches 3-5 add a new privacy-screen class for this, which allows non KMS drivers (and possibly KMS drivers too) to register a privacy-screen device and also adds an interface for KMS drivers to get access to the privacy-screen associated with a specific connector. This is modelled similar to how we deal with e.g. PWMs and GPIOs in the kernel, including separate includes for consumers and providers(drivers). 3. Some drm_connector helper functions to keep the actual changes needed for this in individual KMS drivers as small as possible (patch 6). 4. Make the thinkpad_acpi code register a privacy-screen device on ThinkPads with a privacy-screen (patches 7-8) 5. Make the i915 driver export the privacy-screen functionality through the connector properties on the eDP connector. I was a bit in doubt if I should calls this series a RFC, or just call it v1, since there is no real userspace code using this yet. It was tested using xrandr property access and udevadm event monitoring. I do expect / hope we will have patches for a userspace consumer of the new properties (mutter) ready soon. But since the code is completely ready, including API documentation, I've decided to just call this v1. Hopefully we can get patches for the first userspace consumer of this ready during the review of this.
