func (Config) Validate

func (cfg Config) Validate() error

type Output

type Output struct {
	// Represents the number of GPUs in the system.
	// This is used to determine if ibcore may be expected to use peermem module.
	GPUCount int `json:"gpu_count"`

	ProductName  string                                `json:"product_name"`
	LsmodPeermem nvidia_query.LsmodPeermemModuleOutput `json:"lsmod_peermem"`
}

func ParseOutputJSON

func ParseOutputJSON(data []byte) (*Output, error)

func ParseStateLsmodPeermem

func ParseStateLsmodPeermem(m map[string]string) (*Output, error)

func ParseStatesToOutput

func ParseStatesToOutput(states ...components.State) (*Output, error)

func ToOutput

func ToOutput(i *nvidia_query.Output) *Output

ToOutput converts nvidia_query.Output to Output. It returns an empty non-nil object, if the input or the required field is nil (e.g., i.SMI).
