class RangeValidator

Public Types

enum ResultMaskBits

Values:

enumerator kValid

Cache and range is valid.

enumerator kInvalidCache

Cache is null or unusable.

enumerator kInvalidRange

first-last range is invalid or out of bounds for provided cache

enumerator kMultiplePrimaryCommandBuffersInRange

More than one primary command buffer object is used in range.

enumerator kFirstRangeCallIsBoundary

First call is command buffer initialization call (i.e. vkBeginCommandBuffer)

enumerator kLastRangeCallIsBoundary

Last call is command buffer finalization call (i.e. vkEndCommandBuffer)

Public Functions

RangeValidator(CallableCache *cache)

~RangeValidator()

bool IsValidRangeForMeasurements(uint64_t first, uint64_t last, uint32_t *reason = nullptr, bool checkForNativeCalls = true, bool checkForSingleCmdBuf = true)

Returns true if range [first, last] is measurable.

You can avoid iterating an entire range if you skip the checks checkForNativeCalls, checkForSingleCmdBuf by setting them to false. This will decrease the number of CPU cache misses and improve performance. But you have to perform these checks in the calling function.
