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:
// Provided by VK_VERSION_1_1
typedef struct VkDeviceGroupCommandBufferBeginInfo {
VkStructureType sType;
const void* pNext;
uint32_t deviceMask;
} VkDeviceGroupCommandBufferBeginInfo;
or the equivalent
// Provided by VK_KHR_device_group
typedef VkDeviceGroupCommandBufferBeginInfo VkDeviceGroupCommandBufferBeginInfoKHR;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
deviceMask
is 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.
