| Reserved for future use. Should be 0. More... | |
| uint32_t | allocationCount |
Number of allocations in pAllocations array. More... | |
| const VmaAllocation * | pAllocations |
| Pointer to array of allocations that can be defragmented. More... | |
| VkBool32 * | pAllocationsChanged |
| Optional, output. Pointer to array that will be filled with information whether the allocation at certain index has been changed during defragmentation. More... | |
| uint32_t | poolCount |
Numer of pools in pPools array. More... | |
| const VmaPool * | pPools |
| Either null or pointer to array of pools to be defragmented. More... | |
| VkDeviceSize | maxCpuBytesToMove |
Maximum total numbers of bytes that can be copied while moving allocations to different places using transfers on CPU side, like memcpy(), memmove(). More... | |
| uint32_t | maxCpuAllocationsToMove |
Maximum number of allocations that can be moved to a different place using transfers on CPU side, like memcpy(), memmove(). More... | |
| VkDeviceSize | maxGpuBytesToMove |
Maximum total numbers of bytes that can be copied while moving allocations to different places using transfers on GPU side, posted to commandBuffer. More... | |
| uint32_t | maxGpuAllocationsToMove |
Maximum number of allocations that can be moved to a different place using transfers on GPU side, posted to commandBuffer. More... | |
| VkCommandBuffer | commandBuffer |
| Optional. Command buffer where GPU copy commands will be posted. More... | |
Parameters for defragmentation.
To be used with function vmaDefragmentationBegin().
| uint32_t VmaDefragmentationInfo2::allocationCount |
Number of allocations in pAllocations array.
| VkCommandBuffer VmaDefragmentationInfo2::commandBuffer |
Optional. Command buffer where GPU copy commands will be posted.
If not null, it must be a valid command buffer handle that supports Transfer queue type. It must be in the recording state and outside of a render pass instance. You need to submit it and make sure it finished execution before calling vmaDefragmentationEnd().
Passing null means that only CPU defragmentation will be performed.
| VmaDefragmentationFlags VmaDefragmentationInfo2::flags |
Reserved for future use. Should be 0.
| uint32_t VmaDefragmentationInfo2::maxCpuAllocationsToMove |
Maximum number of allocations that can be moved to a different place using transfers on CPU side, like memcpy(), memmove().
UINT32_MAX means no limit.
| VkDeviceSize VmaDefragmentationInfo2::maxCpuBytesToMove |
Maximum total numbers of bytes that can be copied while moving allocations to different places using transfers on CPU side, like memcpy(), memmove().
VK_WHOLE_SIZE means no limit.
| uint32_t VmaDefragmentationInfo2::maxGpuAllocationsToMove |
Maximum number of allocations that can be moved to a different place using transfers on GPU side, posted to commandBuffer.
UINT32_MAX means no limit.
| VkDeviceSize VmaDefragmentationInfo2::maxGpuBytesToMove |
Maximum total numbers of bytes that can be copied while moving allocations to different places using transfers on GPU side, posted to commandBuffer.
VK_WHOLE_SIZE means no limit.
| const VmaAllocation* VmaDefragmentationInfo2::pAllocations |
Pointer to array of allocations that can be defragmented.
The array should have allocationCount elements. The array should not contain nulls. Elements in the array should be unique - same allocation cannot occur twice. All allocations not present in this array are considered non-moveable during this defragmentation.
| VkBool32* VmaDefragmentationInfo2::pAllocationsChanged |
Optional, output. Pointer to array that will be filled with information whether the allocation at certain index has been changed during defragmentation.
The array should have allocationCount elements. You can pass null if you are not interested in this information.
| uint32_t VmaDefragmentationInfo2::poolCount |
Numer of pools in pPools array.
| const VmaPool* VmaDefragmentationInfo2::pPools |
Either null or pointer to array of pools to be defragmented.
All the allocations in the specified pools can be moved during defragmentation and there is no way to check if they were really moved as in pAllocationsChanged, so you must query all the allocations in all these pools for new VkDeviceMemory and offset using vmaGetAllocationInfo() if you might need to recreate buffers and images bound to them.
The array should have poolCount elements. The array should not contain nulls. Elements in the array should be unique - same pool cannot occur twice.
Using this array is equivalent to specifying all allocations from the pools in pAllocations. It might be more efficient.
