Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of testing a system-on-chip (SoC). The method includes generating data for a plurality of audio channels. The data comprises first data corresponding to a first audio channel and second data corresponding to a second audio channel. The method further includes outputting the first audio channel over a first output port of the SoC for output by a speaker. The method further includes outputting the second audio channel over a second output port. The method further includes looping back the second audio channel from the second output port to a first input port of the SoC as third data. The method further includes comparing the third data to the second data. The method further includes determining if the SoC is operating correctly based on the comparison of the third data to the second data.

Abstract: Systems, methods, and devices of the various embodiments enable dynamic configuration of a number of display regions of interest (ROIs) associated with safety critical content presented on a display, such as a vehicle display. Various embodiments may enable verification of data integrity for ROIs on a display. Various embodiments may enable the selection of different sets of display ROIs from a plurality of independent sets of display ROIs each associated with its own set of stored integrity check values (ICVs). Various embodiments may enable stored ICVs to be used to verify the data integrity of ROIs on a display. Various embodiments may enable the set of display ROIs and the associated ICVs for each display ROI to be changed after a number of frames have been displayed.

Abstract: A shared memory may be employed for use with a front end (e.g., a guest virtual machine (GVM) component) and a back end (e.g., native driver, physical virtual machine (PVM) component, hardware, etc.) of a virtualization system to allow the front end to influence (e.g., control) the occurrence of the virtual interrupt request (IRQ) forwarding from the back end. The shared memory may include one or more flags or one or more lists to allow the front end to control the behavior of the back end virtual IRQ forwarding logic without causing the back end to stop its existing processes. Thus, the front end may multiple numerous input/output (IO) requests, but the front end may only check the completion of some of the requests (e.g., based on work items written into the shared memory, by the front end, for back end processing and back end IRQ forwarding).
