Module linux 

Linux-specific platform detection: GPU, ROCm, and hardware introspection.

Provides GPU detection with a three-tier fallback chain (rocminfo → lspci → sysfs), GPU architecture correction from marketing names, ROCm version detection from /opt/rocm/.info/version, and ROCm path search with priority ordering.

Fallback Chain

1. rocminfo — parses agent entries for AMD GPU devices
2. lspci — scans PCI bus for AMD VGA devices
3. sysfs (/sys/class/drm) — reads vendor IDs from DRM card entries

ROCm Path Priority

1. ROCm_PATH environment variable
2. /opt/rocm (standard location)
3. /opt/rocm-* versioned directories (sorted newest-first)
4. /usr/lib/rocm, /usr/local/rocm (Arch AUR paths)
5. /usr/lib/rocm-* versioned paths (Arch AUR)
6. Derived from which rocminfo

Functions

detect_gpu

Detect AMD GPUs using the three-tier fallback chain (rocminfo → lspci → sysfs).

detect_rocm_path

Detect ROCm installation path by searching common locations in priority order.

get_correct_gfx_from_marketing_name

Map GPU marketing name to correct gfx architecture.

get_rocm_version

Detect ROCm version using multiple fallback methods.
