These days, Software-Defined Vehicles (SDVs) are becoming crucial in complex automotive system development. In this context, VirtIO, in particular, has played a key role and has become increasingly popular over the last couple of years.
Although VirtIO is an effective and useful method in development, it has one significant drawback in terms of performance: the overhead caused by its virtualization scheme. This overhead generates latency across multiple metrics, degrading system performance compared to a native environment.
Such latency is critical not only for ADAS, which requires mixed criticality, but also for Meter Clusters, Digital Cockpits, and IVI systems. This latency often causes certain metrics to exceed acceptable levels, presenting a major challenge for VirtIO in automotive systems.
This session will cover the following:
First: The current status of VirtIO, the roadmap by the OASIS Committee, and the role of AGL.
Second: The mechanism behind how this latency occurs.
Third: The specific areas where latency occurs.
Finally: Countermeasures to mitigate this latency.
