3 Multimedia Support Based vDRM on Linux

Due to the IVI/cluster/ADAS project has a specific requirement for boot time. Different with the standard DRM display framework. The vDRM framework can adjust the multicore architecture and improve the boot time performance.

For PSDKLA + VISION-SDK architecture, we often use early boot late-attach. Figure 3-1 shows the boot flow.

For some application that based omapdrm will not work with virtual DRM. So we need to adjust the vDRM requirement. Here are some examples: Gstreamer/viddec3test/modetest/kmscube. Those binaries can download from the attachment.
