C Specification
If the pNext chain of VkCommandBufferBeginInfo includes a
VkDeviceGroupCommandBufferBeginInfo structure, then that structure
includes an initial device mask for the command buffer.
The VkDeviceGroupCommandBufferBeginInfo structure is defined as:
typedef struct VkDeviceGroupCommandBufferBeginInfo {
VkStructureType sType;
const void* pNext;
uint32_t deviceMask;
} VkDeviceGroupCommandBufferBeginInfo;
or the equivalent
typedef VkDeviceGroupCommandBufferBeginInfo VkDeviceGroupCommandBufferBeginInfoKHR;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure. -
deviceMaskis the initial value of the command buffer’s device mask.
Description
The initial device mask also acts as an upper bound on the set of devices that can ever be in the device mask in the command buffer.
If this structure is not present, the initial value of a command buffer’s device mask is set to include all physical devices in the logical device when the command buffer begins recording.
