    Abstract: In examples, properties of an execution environment may be verified for a game session to comply with security policies based at least on analyzing attestation reports generated using one or more host devices. Content items may be associated with the game session to indicate the verification for presentation with a live stream video of the game session, in a pre-recorded video of the game session, and/or in another user interface associated with the game session. A record of the verification may be stored in a database, and the database may be queried to display the content item and/or to determine whether the verification occurred. The attestation reports may include an attestation report(s) generated using an input device(s) used to capture user inputs for the game session, such as an input device used to control the game session and/or provide a video capture of the player during the game session.

    Abstract: In various examples, latency of human interface devices (HIDs) may be accounted for in determining an end-to-end latency of a system. For example, when an input is received at an HID, an amount of time for the input to reach a connected device may be computed by the HID and included in a data packet transmitted by the HID device to the connected device. The addition of the peripheral latency to the end-to-end latency determination may provide a more comprehensive latency result for the system and, where the peripheral latency of an HID is determined to have a non-negligible contribution to the end-to-end latency, a new HID component may be implemented, a configuration setting associated with the HID component may be updated, and/or other actions may be taken to reduce the contribution of the peripheral latency to the overall latency of the system.

    Abstract: Disclosed are apparatuses, systems, and techniques that reduce latency of frame processing pipelines. The techniques include but are not limited to causing a display to set a refresh rate that matches a frame rendering rate of an application and rendering, with the frame rendering rate, a plurality of frames. Rendering frames includes generating, using a first processing unit, sets of instructions associated with respective frames and generated starting at times spaced with the refresh rate, processing, using a second processing unit, the sets of instructions to render the frames, and causing the display to display the rendered frames.

    Abstract: In examples, a VM may receive and aggregate a first attestation report corresponding to a
    CPU and a second attestation report corresponding to a GPU. The aggregated data may be provided to an attestation service, which may verify the attestation reports indicate a TCB is to include the VM and GPU state data and is to isolate the GPU state data and the VM from an untrusted host OS. Based at least on the TCB being verified, the VM may perform one or more operations using the TCB. The TCB may include a trusted hypervisor to isolate the VM and GPU state data within the GPU(s) from the untrusted host OS. The trusted hypervisor may prevent the host OS from accessing device memory assigned to the VM based at least on controlling an IOMMU and/or second-level address translation (SLAT) used to access the data.
