C Specification
Bits which can be set in vkCmdPipelineBarrier::dependencyFlags,
specifying how execution and memory dependencies are formed, are:
// Provided by VK_VERSION_1_0
typedef enum VkDependencyFlagBits {
VK_DEPENDENCY_BY_REGION_BIT = 0x00000001,
// Provided by VK_VERSION_1_1
VK_DEPENDENCY_DEVICE_GROUP_BIT = 0x00000004,
// Provided by VK_VERSION_1_1
VK_DEPENDENCY_VIEW_LOCAL_BIT = 0x00000002,
// Provided by VK_EXT_attachment_feedback_loop_layout
VK_DEPENDENCY_FEEDBACK_LOOP_BIT_EXT = 0x00000008,
// Provided by VK_KHR_maintenance8
VK_DEPENDENCY_QUEUE_FAMILY_OWNERSHIP_TRANSFER_USE_ALL_STAGES_BIT_KHR = 0x00000020,
// Provided by VK_KHR_maintenance9
VK_DEPENDENCY_ASYMMETRIC_EVENT_BIT_KHR = 0x00000040,
// Provided by VK_KHR_multiview
VK_DEPENDENCY_VIEW_LOCAL_BIT_KHR = VK_DEPENDENCY_VIEW_LOCAL_BIT,
// Provided by VK_KHR_device_group
VK_DEPENDENCY_DEVICE_GROUP_BIT_KHR = VK_DEPENDENCY_DEVICE_GROUP_BIT,
} VkDependencyFlagBits;
Description
-
VK_DEPENDENCY_BY_REGION_BIT specifies that dependencies will be split into multiple framebuffer-local regions according to the (x,y,layer,sample) coordinates.
-
VK_DEPENDENCY_VIEW_LOCAL_BIT specifies that dependencies will be split into multiple framebuffer-local regions according to the view.
-
VK_DEPENDENCY_DEVICE_GROUP_BIT specifies that dependencies are non-device-local.
-
VK_DEPENDENCY_FEEDBACK_LOOP_BIT_EXT specifies that the render pass will write to and read from the same image with feedback loop enabled.
-
VK_DEPENDENCY_QUEUE_FAMILY_OWNERSHIP_TRANSFER_USE_ALL_STAGES_BIT_KHR specifies that source and destination stages are not ignored when performing a queue family ownership transfer.
-
VK_DEPENDENCY_ASYMMETRIC_EVENT_BIT_KHR specifies that vkCmdSetEvent2 must only include the source stage mask of the first synchronization scope, and that vkCmdWaitEvents2 must specify the complete barrier.
