Just double-checking - before a given provider adapts, the global klog calls will continue working as before, right?

Propagate the received context to downstream work.

These methods accept ctx but create a new context before GPU detection, node lookup, refresh, or debug work. This prevents caller cancellation, deadlines, and contextual logging values from reaching those operations.

  • cluster-autoscaler/cloudprovider/alicloud/alicloud_cloud_provider.go#L128-L130: pass ctx to gpu.GetNodeGPUFromCloudProvider.
  • cluster-autoscaler/cloudprovider/civo/civo_cloud_provider.go#L90-L98: pass ctx to group.Nodes.
  • cluster-autoscaler/cloudprovider/civo/civo_cloud_provider.go#L168-L170: pass ctx to gpu.GetNodeGPUFromCloudProvider.
  • cluster-autoscaler/cloudprovider/cloudstack/cloudstack_cloud_provider.go#L130-L132: pass ctx to gpu.GetNodeGPUFromCloudProvider.
  • cluster-autoscaler/cloudprovider/huaweicloud/huaweicloud_cloud_provider.go#L187-L189: pass ctx to gpu.GetNodeGPUFromCloudProvider.

  • cluster-autoscaler/cloudprovider/magnum/magnum_cloud_provider.go#L194-L197: pass ctx to nodegroup.Debug.
  • cluster-autoscaler/cloudprovider/ovhcloud/ovh_cloud_provider.go#L192-L205: add ctx parameters to the lookup helpers and pass ctx to NodeGroups and Nodes.
  • cluster-autoscaler/cloudprovider/ovhcloud/ovh_cloud_provider.go#L301-L303: pass ctx to gpu.GetNodeGPUFromCloudProvider.
  • cluster-autoscaler/cloudprovider/ovhcloud/ovh_cloud_provider.go#L311-L324: pass ctx to ListNodePools.
  • cluster-autoscaler/cloudprovider/scaleway/scaleway_cloud_provider.go#L244-L249: pass ctx to gpu.GetNodeGPUFromCloudProvider.
  • cluster-autoscaler/cloudprovider/scaleway/scaleway_cloud_provider.go#L257-L279: pass ctx to ListPools and ListNodes.
  • cluster-autoscaler/cloudprovider/tencentcloud/tencentcloud_cloud_provider.go#L141-L145: pass ctx to gpu.GetNodeGPUFromCloudProvider.
Proposed pattern 
- return gpu.GetNodeGPUFromCloudProvider(context.TODO(), provider, node)
+ return gpu.GetNodeGPUFromCloudProvider(ctx, provider, node)

- nodes, err := group.Nodes(context.TODO())
+ nodes, err := group.Nodes(ctx)

- pools, err := client.ListPools(context.Background(), clusterID)
+ pools, err := client.ListPools(ctx, clusterID)
