Detailed Description

The passthrough implementation: one dedicated VkDeviceMemory per buffer, mapped for its lifetime. Every allocation it returns owns its memory and starts at offset zero.

Constructor & Destructor Documentation

DedicatedBufferAllocator()

donner::gpu::vulkan::DedicatedBufferAllocator::DedicatedBufferAllocator ( const VkPhysicalDeviceMemoryProperties & memoryProperties )

inlineexplicit

Parameters

memoryProperties

Physical device memory properties, for memory-type selection.

Member Function Documentation

allocate()

Result< BufferAllocation > donner::gpu::vulkan::DedicatedBufferAllocator::allocate ( const VulkanApi & api, VkDevice device, VkBuffer buffer, std::string_view label )

overridevirtual

Provides memory for buffer and binds it.

Parameters

api	Resolved device entry points.
device	Device owning buffer.
buffer	Buffer to bind memory into.
label	Buffer label, for failure messages.

Implements donner::gpu::vulkan::BufferSuballocator.

release()

void donner::gpu::vulkan::DedicatedBufferAllocator::release ( const VulkanApi & api, VkDevice device, BufferAllocation & allocation )

overridevirtual

Releases an allocation obtained from allocate.

Parameters

api	Resolved device entry points.
device	Device owning the allocation.
allocation	Allocation to release; left cleared.

Implements donner::gpu::vulkan::BufferSuballocator.
