C Specification
Bits which can be set in VkPipelineCacheCreateInfo::flags,
specifying behavior of the pipeline cache, are:
// Provided by VK_VERSION_1_3, VK_KHR_maintenance8, VK_EXT_pipeline_creation_cache_control
typedef enum VkPipelineCacheCreateFlagBits {
// Provided by VK_VERSION_1_3
VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT = 0x00000001,
// Provided by VK_KHR_maintenance8
VK_PIPELINE_CACHE_CREATE_INTERNALLY_SYNCHRONIZED_MERGE_BIT_KHR = 0x00000008,
// Provided by VK_EXT_pipeline_creation_cache_control
VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT_EXT = VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT,
} VkPipelineCacheCreateFlagBits;Description
-
VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT specifies that all commands that modify the created VkPipelineCache will be externally synchronized. When set, the implementation may skip any unnecessary processing needed to support simultaneous modification from multiple threads where allowed.
-
VK_PIPELINE_CACHE_CREATE_INTERNALLY_SYNCHRONIZED_MERGE_BIT_KHR specifies that when the created VkPipelineCache is used as the
dstCacheparameter of vkMergePipelineCaches, it does not need to be externally synchronized. This flag is mutually exclusive with VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT.
