Linux for Tegra
Linux for Tegra (L4T) is the component that provides the OS components (kernel, file system, drivers, firmware) and the bootloader. Jetpack 6.1 comes with L4T version 36.4, featuring:
- Linux Kernel version 5.15: the previous Jetpack version (5.0) came with Linux Kernel version 5.10.
- Ubuntu 22.04-based root file system: the previous Jetpack version (5.0) came with Ubuntu 20.04-based root file system.
- UEFI-based bootloader: continues from L4T 34.1.
- Support for upstream kernels: allows running kernels newer than 5.14.
- MAXN Super performance mode: available on Jetson Orin Nano Developer Kit, increasing performance up to 1.6x.
- Enhanced Argus Camera Library: reducing CPU utilization by up to 40%.
- Firmware TPM (fTPM) support: provides improved security.
- New GStreamer IPC plugins: nvunixfdsink / nvunixfdsrc for multimedia inter-process communication.
- Predictable Ethernet interface naming: improves networking consistency.
Multimedia API
Included as part of L4T, the Multimedia API allows developers to develop camera-based multimedia applications. It has two main components:
- V4L2 Sensor driver API: the V4L2 API that enables the capture devices, codecs, and scaling functionality.
- Libargus: the proprietary NVIDIA library that allows using the Jetson Image Signal Processor (ISP).
JetPack 6.1 Multimedia API includes performance improvements and new GStreamer-based IPC plugins for buffer sharing.
CUDA
Jetpack 6.1 includes CUDA 12.6 support. CUDA is a parallel computing API for NVIDIA GPUs. NVIDIA's CUDA Toolkit provides the development environment for creating GPU-accelerated applications in C/C++. Table 2 provides the CUDA 12.6 components version information:
