Methods for database recovery for encrypted indexes are performed by systems and devices. A query with a decryption key is received from a client device, where the query modifies an encrypted index of a database using a secure enclave. When events requiring remedial actions for the database occur during the querying, some transactions of the query and later queries are deferred, and a remedial action is initiated that includes restarting the database. A determination of the remedial action being unsuccessful in recovering the encrypted index causes the action to be re-performed until another query having the decryption key is received whereupon the action is performed again to recover the encrypted index utilizing the decryption key. Deferred transactions are then performed with the decryption key. When a database restarts for access without secure enclaves, the encrypted index for the database is invalidated, and the remedial actions are otherwise completed or discarded.

System and method for database recovery for encrypted indexes

Examples described herein generally apply color transforms to visual content. A set of color transforms in a graphics pipeline that are requested by a plurality of applications can be determined. At least one of the set of color transforms or an ordering of the set of color transforms can be modified, based on one or more arbitration rules, to generate an arbitrated set of color transforms. The visual content can be generated for display based at least in part on applying the arbitrated set of color transforms in the graphics pipeline.

Techniques for applying color transforms in rendering visual content

Devices and methods for controlling display brightness may include receiving a brightness input for controlling a luminance level of at least one display in communication with the computer device. The devices and methods may include receiving high dynamic range (HDR) content and standard dynamic range (SDR) content for presentation on at least one display. The devices and methods may include generating adjusted SDR content by using the brightness input to modify luminance of the SDR content. The devices and methods may include blending the adjusted SDR content and the HDR content together to create a composed framebuffer content with the adjusted SDR content and the HDR content and transmitting the composed framebuffer content for presentation on at least one display.
