Where to find driver source after Voyager SDK installation

After installing the Voyager SDK, the Metis driver source code lives in /usr/src/metis-<version>/driver/.

Confirm the installed driver​

Use dkms status to see which driver version is built and installed:

dkms status
metis/1.2.2, 5.10.160, aarch64: installed

In this example, the Metis driver (version 1.2.2) is installed and compiled for kernel 5.10.160 on an ARM64 (aarch64) system.

List the source directory​

ls /usr/src/metis-1.2.2/driver/
axl-pcie-reset.c      conf                          dmabuf-triton-exporter.o      dmabuf-triton-importer.o  metis-dmabuf.h  metis.o

The directory contains:

  • Source files (.c, .h) — the driver code for PCIe operations, DMA buffer management, and device reset.
  • Compiled objects (.ko, .o, .mod*) — built kernel modules, ready to load into the kernel.
  • Build artifacts — the Makefile, configuration files, and module metadata.
