Functions

func GetTrackIDs

func GetTrackIDs(ctx context.Context, s Scope, processor *perfetto.Processor) ([]int64, error)

GetTrackIDs returns all track ids from gpu_track with the given scope.

func IsNumber

func IsNumber(column *perfetto_service.QueryResult_ColumnValues, columnType perfetto_service.QueryResult_ColumnDesc_Type) bool

IsNumber is a checker that checks that the column is a number type.

func ValidateGpuCounters

func ValidateGpuCounters(ctx context.Context, processor *perfetto.Processor, counters []GpuCounter) error

ValidateGpuCounters validates the GPU counters. GPU counters validation will fail in the below cases: 1. Fail to query 2. Missing GPU counter samples 3. Fail to check

func ValidateGpuSlices

func ValidateGpuSlices(ctx context.Context, processor *perfetto.Processor) error

ValidateGpuSlices validates gpu slices, returns nil if all validation passes.

func ValidateVulkanEvents

func ValidateVulkanEvents(ctx context.Context, processor *perfetto.Processor) error

ValidateVulkanEvents validates vulkan events slices, returns nil if all validation passes.

Types

type Checker

type Checker func(column *perfetto_service.QueryResult_ColumnValues, columnType perfetto_service.QueryResult_ColumnDesc_Type) bool

Checker is a function that checks the validity of the values of the given result set column.

func And

func And(cs ...Checker) Checker

And returns a checker that is only valid if all of its arguments are.

func Average

func Average(check func(float64) bool) Checker

Average returns a checker that checks whether the average values meets the condition

func CheckAllEqualTo

func CheckAllEqualTo(num float64) Checker

CheckAllEqualTo returns a checker that checks that all returned value equal the given value.

func CheckAverageApproximateTo

func CheckAverageApproximateTo(num, margin float64) Checker

CheckAverageApproximateTo checks whether the average of the values is within a margin of the given value.

func CheckLargerThanZero

func CheckLargerThanZero() Checker

CheckLargerThanZero is a checker that checks that the values are all greater than zero.

func CheckNonNegative

func CheckNonNegative() Checker

CheckNonNegative is a checker that checks that no value is less than zero.

func ForeachValue

func ForeachValue(check func(float64) bool) Checker

func Not

func Not(c Checker) Checker

Not returns a checker that returns the inverse of the given checker.

type GpuCounter

type GpuCounter struct {
	Id    uint32
	Name  string
	Check Checker
}

GpuCounter represents a GPU counter for which the profiling data is validated.

type Scope

type Scope string

type Validator

type Validator interface {
	Validate(ctx context.Context, processor *perfetto.Processor) error
	GetCounters() []GpuCounter
}

Validator is an interface implemented by the various hardware specific validators.
