# @BLURB: Overlay-wide ROCm version pin feeding the rocm eclass
# @DESCRIPTION:
# The single place the overlay's ROCm toolchain generation is declared.
# Sets ROCM_VERSION — which keys the rocm eclass's amdgpu_targets_*
# IUSE list (Portage filters the AMDGPU_TARGETS env var to flags
# present in IUSE, so a package without the eclass globals gets an
# empty get_amdgpu_flags) — before inheriting rocm, so every
# ROCm-capable package, ggml backends and the sci-ml torch stack
# alike, follows the same version. Bump it HERE when the system ROCm
# moves.
