# Profiled families (AKS/GKE gpuStack): hydrate the recipe with the

…ferences gpu-operator v26.7.0 ships a stale copy of the ComputeDomain CRD in crds/ that marks numNodes required with no default. Helm installs crds/ only when absent and gpu-operator is ordered before nvidia-dra-driver-gpu, so on a fresh cluster the operator's copy wins and the slinky-slurm ComputeDomain CR is rejected with "spec.numNodes: Required value". Pin numNodes: 0 explicitly, which is valid under both CRD copies and is the correct value under IMEXDaemonsWithDNSNames. Also refresh version references the bump made stale: the GPU CI chart pin, a chainsaw comment mirroring the driver-validation rationale, the ccManager and toolkit-hardening comments, and a hand-written sample in the BOM page. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
Verified each version-specific behavioral claim in Go comments against v26.7.0 / DRA 0.5.0 before updating the cited version: transformForDriverInstallDir still early-returns on "", clusterpolicy.yaml still accesses .Values.hostPaths.rootFS unconditionally, the ClusterPolicy CRD still types driverInstallDir as a string, _helpers.tpl still reads .Values.driver.manager.repository, operator.runtimeClass still defaults to nvidia, driverInstallDir still defaults to /run/nvidia/driver, and the DRA chart still defaults nvidiaDriverRoot to "/". The GKE Ubuntu driver-management note is de-versioned rather than re-pinned, since it is a support-matrix claim rather than a chart fact. Docs, demos and example recipes carried the old versions in copyable samples and in one exact-match constraint (== v26.3.3), which would have failed validation against a v26.7.0 deployment. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
…azard gpu-operator v26.7.0 and the standalone DRA driver both ship a computedomains.resource.nvidia.com CRD, and the copies differ: the operator's marks numNodes required with no default. Helm installs crds/ only when absent and gpu-operator is ordered first, so a fresh cluster gets the stricter copy and rejects any ComputeDomain CR omitting numNodes. An upgraded cluster masks this because DRA 0.4.1 already installed the permissive copy, so no upgrade-path e2e would catch a regression here. The guard ignores comment lines: these manifests legitimately discuss "spec.numNodes: Required value" in prose, and a naive substring scan matched that instead of the key — passing even with the key deleted. Verified by deleting numNodes and confirming the test fails, then restoring it. Also fails closed when the walk matches no manifests, so it cannot go silently inert. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
…efresh misspell rejects "analogue"; the US spelling is required by the lint gate. Three stale references the earlier refresh missed: - demos/dynamic.md grepped for 'version: 580' to prove the dynamic value had been removed from baked values. With the pin at 595.91.07 that grep returns 0 whether or not the substitution worked, so the check no longer proved anything. The chainsaw suite it mirrors uses a 999.99.99 sentinel and is unaffected. - the driver-root lockstep comment still named DRA chart 25.12.0 while its own error text had been updated to 0.5.0. - the AKS setup guide still named toolkit v1.19.1 while the manifest it documents now names v1.20.0. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
The guard matched numNodes anywhere in the file. A multi-document manifest where one ComputeDomain sets the key and a second omits it would pass while still failing admission, as would an unrelated resource carrying a numNodes key. No such manifest exists today; scoping per document means adding one cannot silently bypass the guard. Two independent reviews raised this. Dropping the whole-file helper also removes its fake generic signature — it took a key parameter, ignored it in the regex, and panicked on anything but "numNodes". Controls verified both ways: deleting numNodes fails, and appending a second ComputeDomain document without it fails naming document 2. Restoring passes. Also updates two comments in checks_test.go that mirror comments in checks.go which this branch already moved to v26.7.0; the claims were verified against the v26.7.0 chart and still hold. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
…leType The chart deprecated useOpenKernelModules and made it a no-op; the identical NOTE appears in v26.3.3 and v26.7.0 values.yaml, so the key had already stopped having any effect before this pin moved. Our clusters have been running the chart default kernelModuleType: auto regardless of what that line said. Pinning "auto" records today's effective behaviour rather than changing it: it is the chart default on both versions and the fallback the OCP ClusterPolicy template already renders. Setting "open" would pin the intent the dead key expressed, but that is a real behaviour change wherever auto currently selects proprietary, so it needs its own validation rather than riding a version bump. Render goldens move for 46 of 48 leaves. The two that do not, ocp-inference-nim and ocp-training, consume gpu-operator-ocp and its separate values file. Catalog goldens are unchanged because values content affects rendering but not recipe resolution. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
…ype consumers The guard matched numNodes anywhere in the ComputeDomain document, so moving the key to metadata.numNodes still passed while Kubernetes would reject the absent spec.numNodes. Matching a key without its parent is not a weaker check, it is the wrong check. The scanner now requires numNodes as a DIRECT CHILD of spec, walking indentation because the manifests are Helm templates no YAML parser accepts. Adds table cases covering every shape that has fooled a previous version of this scanner or must keep working: present, absent, under metadata, comment-only, nested under spec.channel, and templated. Plus a multi-document case asserting only the offending document is reported. Replacing useOpenKernelModules also broke four consumers that were not updated with it — a chainsaw bundle assertion (which fails CLI E2E), the OpenAPI response example, the query demo output, and the OCP values comment. Changing a values key requires sweeping its consumers, the same discipline applied to the version strings in this branch. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
…lity NVIDIA documents R595 as backward incompatible with P6e-GB200 EFA. R595 drops NVreg_GrdmaPciTopoCheckOverride, the R580-era escape hatch, and substitutes a topology check requiring EFA in an IOMMU group or GPU and EFA under a shared root port. p6e-gb200/gb300 satisfies neither. Proven on p6e-gb300r.36xlarge, not inferred: running the NCCL NET workload under 595 with the preflight bypassed, both nodes selected aws-ofi-nccl/EFA/RDMA and then aborted, with the kernel logging "NVRM: dma-buf attach failed: topology not supported for mapping type FORCE_PCIE". The same two nodes passed NCCL NET at 43.16 GB/s under 580.173.02. Scope is the AWS P6e Grace-Blackwell EFA GPUDirect path. NVLS passed under 595 at 840 GB/s, as did deployment and conformance — NVLink never touches EFA. Holding here is a supported combination rather than an untested one: GPU Operator v26.7.0 lists 580.173.02 as supported (595.91.07 is only its default), and DRA driver 0.5.0 requires >= 580. The chart and DRA bumps are retained. This reverses an argument made earlier on this branch, that driver and chart should move together because holding one back invents an untested pairing. That reasoning did not account for the new driver being unsupported on hardware we ship. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>

Summary
Bumps GPU Operator
v26.3.3→v26.7.0and the NVIDIA DRA driver (base and OCP)0.4.1→0.5.0, and fixes a ComputeDomain CRD conflict that v26.7.0 introduces.The GPU driver is deliberately NOT bumped. It stays at
580.173.02— see "Driver held at 580.173.02" below. R595 is incompatible with P6e EFA, proven on hardware.Allocation behaviour is unchanged:
ClusterPolicywith the device plugin as the whole-GPU advertiser, and the standalone DRA driver serving ComputeDomain/IMEX.GPUClusteris not adopted.Motivation / Context
The catalog is two GPU Operator minors behind. v26.7.0 (2026-08-21) and DRA driver 0.5.0 (2026-08-19) are current, and 0.5.0 lists "Support deployment with the NVIDIA GPU Operator v26.7.0" as a feature — they are the pairing upstream validates.
Fixes: N/A — this is a version sweep, not a defect fix

ComputeDomain CRD conflict — the one behaviour fix here
v26.7.0's chart gained three CRDs its predecessor did not ship, two of them in the
resource.nvidia.comgroup:resource.nvidia.com_computedomains.yamlis also shipped by the standalone DRA driver chart, and gpu-operator's copy is a stale snapshot:spec.required[channel, numNodes][channel]spec.numNodesdefault, nominimumdefault: 0,minimum: 0Helm installs
crds/only when the CRD is absent and never upgrades it, andgpu-operatoris ordered beforenvidia-dra-driver-gpu. So on a fresh cluster the operator's stricter copy wins, andrecipes/components/slinky-slurm/manifests/compute-domain.yaml— which omittednumNodes— would be rejected withspec.numNodes: Required value. Structural defaulting cannot fill it because that copy has nodefault: 0.Fix: pin
numNodes: 0on the CR, plus a regression guard (TestComputeDomainManifestsSetNumNodes) asserting every ComputeDomain manifest in the catalog sets the key, so a future CR cannot reintroduce the hazard. Valid under both copies, and0is the correct value rather than a placeholder — withIMEXDaemonsWithDNSNames=true(the DRA driver default) each IMEX daemon starts immediately instead of waiting for a quorum. It matchesbuildComputeDomain()invalidators/performance/nccl_all_reduce_bw_constraint.go, which already setsnumNodes: 0for the same reason.Reachable in a supported configuration:
gb200-eks-ubuntu-training-slurmis a shipped overlay with UAT coverage, and the CR is aslinky-slurmpre-manifest applied unconditionally. Fresh installs only — an existing cluster keeps the DRA-installed CRD, which is why an upgrade-path test would not surface it.Neither component declares
ownsCRDs: true, so the #2312 Flux CRD-replace path does not correct this on its own.Driver held at 580.173.02 — the one thing this PR does NOT bump
An earlier revision of this branch moved the pin to
595.91.07, the v26.7.0 chart default, arguing that holding a driver back against a newer chart invents an untested pairing. Cluster validation disproved that, and the pin is held.NVIDIA documents R595 as backward incompatible with P6e-GB200 EFA. R595 drops
NVreg_GrdmaPciTopoCheckOverride— the R580-era escape hatch — and substitutes a topology check: EFA must sit in an IOMMU group, or GPU and EFA must share a root port.Measured on
p6e-gb300r.36xlarge, both nodes, identically:Neither condition is met. The failure is proven, not inferred — running the NCCL NET workload under 595 with the preflight bypassed, both nodes selected
aws-ofi-nccl/EFA/RDMA and then aborted:A preserved 2026-08-26 validation on the same two nodes under
580.173.02passed the NET preflight and NCCL NET at 43.16 GB/s, with AICR's transport assertion rejecting Socket — so that was a genuine network-plugin result, and the one-EFA-per-node topology is not the cause.Scope is narrow: the AWS P6e Grace-Blackwell + EFA GPUDirect path. Not generic EKS, not generic GB200/GB300, not DRA, not NVLS. Under 595, NVLS passed at 840 GB/s and deployment and conformance passed 8/8 — NVLink never touches EFA.
Holding is a supported combination, not an untested one. GPU Operator v26.7.0 lists
580.173.02as supported (595.91.07is merely its default), and DRA driver 0.5.0 requires>= 580.Do not substitute a newer R580 patch without re-validating EFA —
580.173.02is the exact measured baseline.gcp-driver-installeris unchanged at580.173.02That component requests a driver from the node's COS release, and
cos-gpu-installervalidates the request against the COS build's curated per-GPU-type list — an unqualified pin crash-loops the DaemonSet. It is unchanged and, now that the GPU Operator pin is also held at580.173.02, the two happen to agree. They remain independent paths: GKE COS setsdriver.enabled: false, so the GPU Operator pin is inert there, and a future move of either must be validated on its own terms.GPUClusteris not adoptedv26.7.0 introduces it, but it ships experimental and
deployCR: false, and it forces whole-GPU DRA cluster-wide, which cannot express today's default. Tracked in #2403. This bump is allocation-neutral by construction.useOpenKernelModulesreplaced withkernelModuleTypedriver.useOpenKernelModules: truewas a no-op. The chart deprecated it and the identical note appears in both v26.3.3 and v26.7.0values.yaml, so the key had already stopped having any effect before this pin moved — our clusters have been running the chart defaultkernelModuleType: autoregardless of what that line said.Replaced with an explicit
kernelModuleType: auto. That records today's effective behaviour rather than changing it: it is the chart default on both versions, and it is the fallback the OCP ClusterPolicy template already renders (components/gpu-operator-ocp/manifests/clusterpolicy.yaml). Per the ClusterPolicy CRD,autoselects the recommended module type from the host's GPU devices and driver branch, which yields open modules on Blackwell/Grace where they are required.Setting
"open"instead would pin the intent the dead key expressed — but that IS a behaviour change on any hardware whereautocurrently selects proprietary, so it needs its own validation rather than riding a version bump.Render goldens move for 46 of 48 leaves as a result. The two that do not —
ocp-inference-nimandocp-training— consumegpu-operator-ocpand its separate values file. Catalog goldens are unchanged, because values content affects rendering but not recipe resolution.Operand versions carried by the chart bump
DCGM's base image moves from Ubuntu 22.04 to 24.04.
DRA driver 0.5.0's new capabilities (
HostManagedIMEXDaemon,FabricManagerPartitioning,ConsumableShares,DRAListTypeAttributes) are all alpha and default-off, so the bump changes no behaviour by itself. It carries ComputeDomain fixes relevant to our usage: CD domain ID validated before IMEX config generation, and no longer failing on incomplete fabric registration on non-MNNVL nodes. ChartkubeVersionis unchanged on both charts (>= 1.16.0-0,>= 1.32.0-0).Stale version references refreshed
The bump made a number of version-specific claims stale. Each behavioural claim in Go comments was re-verified against v26.7.0 / DRA 0.5.0 before its cited version was updated — all seven still hold:

Also refreshed: the GPU CI chart pin in
.settings.yaml(so the GPU lanes exercise the chart the catalog ships rather than one two minors behind), a chainsaw comment mirroring the driver-validation rationale, theccManagernote (ccManager.enabled: truere-verified in v26.7.0), the AKS toolkit-hardening note (the v1.20.0 changelog shows no change to the volume-mount device-request path, so the security rationale stands), and copyable samples indocs/,demos/andexamples/.One of those was more than cosmetic:

Both were regenerated withAICR_UPDATE_GOLDEN=1.gpu-operatorandnvidia-dra-driver-gpucome frombase.yaml, so every leaf inherits them. A partial change would have signalled leakage into a subset of recipes.

After the rebase ontomain, the golden parity suites inpkg/recipeandpkg/bundlerwere re-run against the rebased head and pass, confirming the two commits picked up (#2445, #2448) did not invalidate the regenerated golden files. The only SDK surface changeapi-diffreports is compatible:(*Config).DRAEvictionNodeLabel: added, from the separately-merged #2401.Cluster validation:

The driver is held at 580.173.02 as a result.Re-validated after reverting the driver. The bundle diff against what was deployed was exactly one line (

Covers NCCL/OFI and MNNVL/IMEX on the held driver.The 595 -> 580 downgrade was exercised on live nodes, since that is the path an existing cluster takes on upgrade. It completed on both nodes; module unload took roughly five minutes per node, during which the driver-manager parks at

Verify recipe evidence (warning-only)check reports 10 pointers across 8 protected recipes asstale:gb200-eks-ubuntu-training,gb300-eks-ubuntu-inference-dynamo,gb300-eks-ubuntu-training-kubeflow,h100-aks-ubuntu-inference-dynamo,h100-aks-ubuntu-training-kubeflow,h100-aks-ubuntu-training,h100-gke-cos-training,rtx-pro-6000-eks-ubuntu-inference-dynamo.That is the expected consequence of changing pinned versions: the recipe digest moves, so previously-signed evidence no longer matches it. It is the warning gate doing its job, not a defect in this change.
It does not gate merge. That check is warning-only by design (its own workflow: "Workflow 2 of 2 for the warning-only recipe-evidence gate"), and it is not in
main's required status checks. The separate blocking evidence gate isevidence-pointer-contract.yaml, which enforces the on-disk pointer contract for committed pointers — this PR adds none, so it has nothing to trip.Three additional entries report
registry-forbidden (HTTP 401). That is a fork-registry access limitation (the fork'saicr-evidencepackage is not public), unrelated to this diff and equally true of any fork PR.Regenerating evidence against the new pins is hardware-gated downstream work for each recipe's owner, tracked separately from this bump.
Risk Assessment
A driver version change rolls every GPU node in the operator-managed families. The diff is small and easily reverted, but its runtime blast radius is the whole GPU fleet, and the EFA path has prior history with driver-validation strictness.
Rollout notes: Operator-managed families (EKS and the base default) take a driver upgrade, which drains and reloads GPU nodes. Provider-installed families (AKS, GKE COS, OKE) keep their host driver; only operands move. v26.7.0 adds in-place driver pod restarts when the driver configuration digest is unchanged, so cosmetic chart-label changes no longer drain nodes — but this bump does change the driver, so nodes will roll.
