Detection Guidance

Detection involves checking the installed ROCm version and affected GPU models. Verify if your system uses AMD Instinct GPUs (MI210, MI250, MI250X, MI300A, MI300X, MI308X, MI325X, MI350X, MI355X) and confirm if ROCm version is below 7.14. Use commands like 'rocm-smi --version' or 'apt list --installed | grep rocm' to check versions.
