Synopsis

createValidationCacheEXT :: forall io. MonadIO io => Device -> ValidationCacheCreateInfoEXT -> ("allocator" ::: Maybe AllocationCallbacks) -> io ValidationCacheEXT Source #

vkCreateValidationCacheEXT - Creates a new validation cache

Parameters

  • device is the logical device that creates the validation cache object.
  • pCreateInfo is a pointer to a ValidationCacheCreateInfoEXT structure containing the initial parameters for the validation cache object.
  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.
  • pValidationCache is a pointer to a ValidationCacheEXT handle in which the resulting validation cache object is returned.

Description

Note

Applications can track and manage the total host memory size of a validation cache object using the pAllocator. Applications can limit the amount of data retrieved from a validation cache object in getValidationCacheDataEXT. Implementations should not internally limit the total number of entries added to a validation cache object or the total host memory consumed.

Once created, a validation cache can be passed to the createShaderModule command by adding this object to the ShaderModuleCreateInfo structure’s pNext chain. If a ShaderModuleValidationCacheCreateInfoEXT object is included in the ShaderModuleCreateInfo::pNext chain, and its validationCache field is not NULL_HANDLE, the implementation will query it for possible reuse opportunities and update it with new content. The use of the validation cache object in these commands is internally synchronized, and the same validation cache object can be used in multiple threads simultaneously.

Note

Implementations should make every effort to limit any critical sections to the actual accesses to the cache, which is expected to be significantly shorter than the duration of the createShaderModule command.

Valid Usage (Implicit)

  • device must be a valid Device handle

Return Codes

Success
Failure

withValidationCacheEXT :: forall io r. MonadIO io => (io ValidationCacheEXT -> (ValidationCacheEXT -> io ()) -> r) -> Device -> ValidationCacheCreateInfoEXT -> Maybe AllocationCallbacks -> r Source #

A convenience wrapper to make a compatible pair of calls to createValidationCacheEXT and destroyValidationCacheEXT

To ensure that destroyValidationCacheEXT is always called: pass bracket (or the allocate function from your favourite resource management library) as the first argument. To just extract the pair pass '(,)' as the first argument.

destroyValidationCacheEXT :: forall io. MonadIO io => Device -> ValidationCacheEXT -> ("allocator" ::: Maybe AllocationCallbacks) -> io () Source #

vkDestroyValidationCacheEXT - Destroy a validation cache object

Parameters

  • device is the logical device that destroys the validation cache object.
  • validationCache is the handle of the validation cache to destroy.
  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.

Valid Usage

  • If AllocationCallbacks were provided when validationCache was created, a compatible set of callbacks must be provided here
  • If no AllocationCallbacks were provided when validationCache was created, pAllocator must be NULL

Valid Usage (Implicit)

  • device must be a valid Device handle
  • If validationCache is not NULL_HANDLE, validationCache must be a valid ValidationCacheEXT handle
  • If pAllocator is not NULL, pAllocator must be a valid pointer to a valid AllocationCallbacks structure
  • If validationCache is a valid handle, it must have been created, allocated, or retrieved from device

Host Synchronization

  • Host access to validationCache must be externally synchronized

getValidationCacheDataEXT :: forall io. MonadIO io => Device -> ValidationCacheEXT -> io (Result, "data" ::: ByteString) Source #

vkGetValidationCacheDataEXT - Get the data store from a validation cache

Parameters

  • device is the logical device that owns the validation cache.
  • validationCache is the validation cache to retrieve data from.
  • pDataSize is a pointer to a value related to the amount of data in the validation cache, as described below.
  • pData is either NULL or a pointer to a buffer.

Description

If pData is NULL, then the maximum size of the data that can be retrieved from the validation cache, in bytes, is returned in pDataSize. Otherwise, pDataSize must point to a variable set by the user to the size of the buffer, in bytes, pointed to by pData, and on return the variable is overwritten with the amount of data actually written to pData.

If pDataSize is less than the maximum size that can be retrieved by the validation cache, at most pDataSize bytes will be written to pData, and getValidationCacheDataEXT will return INCOMPLETE. Any data written to pData is valid and can be provided as the pInitialData member of the ValidationCacheCreateInfoEXT structure passed to createValidationCacheEXT.

Two calls to getValidationCacheDataEXT with the same parameters must retrieve the same data unless a command that modifies the contents of the cache is called between them.

Applications can store the data retrieved from the validation cache, and use these data, possibly in a future run of the application, to populate new validation cache objects. The results of validation, however, may depend on the vendor ID, device ID, driver version, and other details of the device. To enable applications to detect when previously retrieved data is incompatible with the device, the initial bytes written to pData must be a header consisting of the following members:

Offset Size Meaning
0 4 length in bytes of the entire validation cache header written as a stream of bytes, with the least significant byte first
4 4 a ValidationCacheHeaderVersionEXT value written as a stream of bytes, with the least significant byte first
8 UUID_SIZE a layer commit ID expressed as a UUID, which uniquely identifies the version of the validation layers used to generate these validation results

Layout for validation cache header version VALIDATION_CACHE_HEADER_VERSION_ONE_EXT

The first four bytes encode the length of the entire validation cache header, in bytes. This value includes all fields in the header including the validation cache version field and the size of the length field.

The next four bytes encode the validation cache version, as described for ValidationCacheHeaderVersionEXT. A consumer of the validation cache should use the cache version to interpret the remainder of the cache header.

If pDataSize is less than what is necessary to store this header, nothing will be written to pData and zero will be written to pDataSize.

Valid Usage (Implicit)

  • device must be a valid Device handle
  • validationCache must be a valid ValidationCacheEXT handle
  • pDataSize must be a valid pointer to a size_t value
  • If the value referenced by pDataSize is not 0, and pData is not NULL, pData must be a valid pointer to an array of pDataSize bytes
  • validationCache must have been created, allocated, or retrieved from device

Return Codes

Success
Failure

mergeValidationCachesEXT :: forall io. MonadIO io => Device -> ("dstCache" ::: ValidationCacheEXT) -> ("srcCaches" ::: Vector ValidationCacheEXT) -> io () Source #

vkMergeValidationCachesEXT - Combine the data stores of validation caches

Parameters

  • device is the logical device that owns the validation cache objects.
  • dstCache is the handle of the validation cache to merge results into.
  • srcCacheCount is the length of the pSrcCaches array.
  • pSrcCaches is a pointer to an array of validation cache handles, which will be merged into dstCache. The previous contents of dstCache are included after the merge.

Description

Note

The details of the merge operation are implementation dependent, but implementations should merge the contents of the specified validation caches and prune duplicate entries.

Valid Usage

  • dstCache must not appear in the list of source caches

Valid Usage (Implicit)

  • device must be a valid Device handle
  • dstCache must be a valid ValidationCacheEXT handle
  • pSrcCaches must be a valid pointer to an array of srcCacheCount valid ValidationCacheEXT handles
  • srcCacheCount must be greater than 0
  • dstCache must have been created, allocated, or retrieved from device
  • Each element of pSrcCaches must have been created, allocated, or retrieved from device

Host Synchronization

  • Host access to dstCache must be externally synchronized

Return Codes

Success
Failure
