fix(device/hygon): validate DCU count and default DCU count to 1 for memory/core-only requests - #2728
Conversation
📝 WalkthroughWalkthrough
ChangesHygon admission handling
Estimated code review effort: 2 (Simple) | ~15 minutes Merge Risk: 🔵 Low · up to The change improves DCU count validation and defaulting, but malformed DCU core quantities can still pass admission and the related tests do not fully verify rejection behavior. The PR is mergeable with explicit owner follow-up on core-quantity validation and test assertions. Possibly related issues

- Around line 95-135: Update MutateAdmission to normalize each Hygon resource
from Limits first, falling back to Requests when omitted, so request-only dCUs
are validated consistently. Apply the existing positive-integer validation to
HygonResourceCount and the 1–100 validation to HygonResourceCores, while
preserving current mutation behavior and adding request-only test coverage.

dcucores 0 and above 100 were accepted before, nvidia clamps instead of rejecting. this is user facing, the release note says none.

HygonResourceMemory and HygonResourceCores are constants, the empty string checks are always true. drop them.
