Abstract: Timestamp synchronization may be performed by determining a time offset between a first virtual machine having a first virtual clock counter of a computing system and a second virtual machine having a second virtual clock counter of the computing system; and adjusting timestamps of traces with timestamps based on the second virtual clock counter according to the time offset.

Abstract: In general, techniques are described by which to provide streaming via a hardware abstraction layer. A cartridge comprising a memory, and a processor may be configured to perform the techniques. The processor may execute a second version of an operating system, and receive a stream, via an interface and to a first version of the operating system executing on a processor of a head unit of a vehicle, information relating to an application executing in the application layer exposed by the first version of the operating system. The information relating to the application may include a first function call that conforms with the first version of the operating system, where the cartridge is communicatively coupled to the head unit. The interface may transform the first function call to a second function call that conforms with the second version of the operating system.
