Public Member Functions | |
| Buffer< VkCommandBuffer > | allocateComputeCommandBuffers (uint04 count) const |
| Allocate a batch of command buffers in a single Vulkan call. | |
| VkCommandBuffer | batchCommandBuffer () const |
| Returns the active batch command buffer, or VK_NULL_HANDLE if no batch is active. | |
| VkCommandBuffer | beginComputeCommands () const |
| Allocate and begin a one-time-use compute command buffer. | |
| void | beginTransferBatch () const |
| Begin a transfer batch. | |
| VkCommandPool | computeCommandPool () const |
| Get the compute command pool. | |
| uint04 | computeFamilyIndex () const |
| Index of the compute queue family. | |
| VkQueue | computeQueue () const |
| Get the compute queue. | |
| VkDevice | device () const |
| Get the VkDevice handle. | |
| void | endComputeCommands (VkCommandBuffer cmd, bool wait_for_completion) const |
| End, submit, and optionally wait for a compute command buffer. | |
| void | endTransferBatch () const |
| End the transfer batch: submit the batched command buffer and wait for completion. | |
| uint04 | findMemoryType (uint04 type_filter, uint04 properties) const |
| Find a memory type index matching the given filter and properties. | |
| void | freeComputeCommandBuffers (const Buffer< VkCommandBuffer > &cmds) const |
| Free a batch of command buffers. | |
| bool | hasDedicatedComputeQueue () const |
| Whether the compute queue is dedicated (not the graphics queue). | |
| void | resetComputeCommandBuffer (VkCommandBuffer cmd) const |
| Reset a previously submitted (or freshly allocated) command buffer and begin recording. | |
| void | submitComputeCommands (VkCommandBuffer cmd) const |
| End and submit a command buffer without waiting or freeing. | |
| bool | supportsCompute () const |
| Whether this device has a usable compute queue. | |
| const ConstPointer< VulkanDevice > & | vulkanDevice () const |
| Access the underlying VulkanDevice. | |
| void | waitComputeQueue () const |
| Block until all work on the compute queue has completed. | |
Wraps a VulkanDevice with compute-specific queue discovery and command pool management.
Discovers a queue family supporting VK_QUEUE_COMPUTE_BIT (preferring a dedicated compute queue when available for async overlap with graphics), creates a dedicated command pool, and provides helpers for one-shot compute dispatches.
Definition at line 45 of file VulkanComputeDevice.h.
Allocate a batch of command buffers in a single Vulkan call.
Returned buffers are in the initial state — call resetComputeCommandBuffer() to transition to recording before use.
| void VulkanComputeDevice::beginTransferBatch | ( | ) | const |
Begin a transfer batch.
All VulkanComputeBuffer::copyBuffer() calls between beginTransferBatch() and endTransferBatch() are recorded into a single command buffer and submitted once, avoiding per-buffer GPU round-trips.
| void VulkanComputeDevice::resetComputeCommandBuffer | ( | VkCommandBuffer | cmd | ) | const |
Reset a previously submitted (or freshly allocated) command buffer and begin recording.
Reusable across phases without reallocating.
| void VulkanComputeDevice::submitComputeCommands | ( | VkCommandBuffer | cmd | ) | const |
End and submit a command buffer without waiting or freeing.
Caller must call waitComputeQueue() before reuse or free.
