Capability-gated acceleration rollouts

Summary#

Default-enabling an optimized backend should depend on the exact capability it needs, not on a broad platform signal such as a vendor or runtime family. Detect the real hardware or runtime feature, keep explicit enable/disable overrides, and let unsupported environments fall back safely. Treat incidents from unsupported sub-platforms as rollout-scope mistakes, not edge-case noise.

Problem#

A platform-wide auto-enable can hang devices or crash workloads on subsets that lack the required instruction set, while making the fast path look 'generally supported' when it is not.

Solution#

Gate activation on concrete architecture or feature checks, keep conservative fallbacks, and expose force-enable and force-disable switches for operators and debugging.

Failure Modes#

Using OS, driver, or platform family as the only gate
Removing the fallback path before feature detection is proven reliable
Omitting manual overrides, which blocks mitigation and diagnosis
Silent fallback hides that the rollout is too conservative or broken
