The techniques described herein use an edge device to manage the security for a data stream being ingested by a tenant and a cloud platform. The creation of the data stream for ingestion occurs in an environment that is trusted by a tenant (e.g., an on-premises enterprise network). The cloud platform that is part of the data stream ingestion process is outside this trusted environment, and thus, the tenant loses an element of security when ingesting data streams for cloud storage and/or cloud processing. Accordingly, the edge device is configured on a trust boundary so that the data stream ingestion process associated with a cloud platform is secured, or trusted by the tenant. The edge device is configured to encrypt the data stream using a data encryption key and/or manage the protection of the data encryption key.

Secure data ingestion with edge computing

Methods and devices for presenting an image in an atomic manner across a plurality of displays of a computer device from a single buffer shared by the plurality of displays may include synchronizing the plurality of displays of the computer device. The methods and devices may initiate an atomic present request to present an image frame on the plurality of displays including a first display and a second display, the atomic present request may identify at least a first display texture and a second display texture from a plurality of display textures stored in the single buffer corresponding to the image frame and that the first display texture corresponds to a first display and the second display texture corresponds to a second display. The devices and methods may transmit a bundled set of first image frame data and second image frame data from the single buffer to a display driver.

Mechanism to present in an atomic manner a single buffer that covers multiple displays

Described are examples for adjusting display level properties across multiple displays. One or more ranges of display brightness capability values that are supported by a given display device can be received for multiple display devices. For each of the multiple display devices, at least a portion of display brightness capability values in the one or more ranges of display brightness capability values can be mapped to selectable brightness levels available in an operating system. One of the selectable brightness levels can be determined as selected via the operating system. For each of the multiple display devices, a corresponding display brightness capability value mapped to the one of the selectable brightness levels can be determined and indicated to each of the multiple display devices, such that the multiple display devices may set different display brightness capability value brightness, but the brightness may be perceptually similar across the display devices.
