When we'll call commitAndNextCommandBuffer, we'll have to wait for this semaphore on to execute STAGE_COLOR_ATTACHMENT_OUTPUT_BIT.

getCopyEncoder()

void Ogre::VulkanQueue::getCopyEncoder	(	const BufferPacked *	buffer,
		TextureGpu *	texture,
		const bool	bDownload,
		CopyEncTransitionMode::CopyEncTransitionMode	transitionMode
	)

Call this function when you need to start copy/transfer operations.

Remarks

buffer and texture pointers cannot be both nullptr at the same time

You don't have to pair every getCopyEncoder call with an endCopyEncoder call. In fact this is discouraged.

Keep calling getCopyEncoder until you're done with all transfer operations

See also

VulkanQueue::prepareForUpload

VulkanQueue::prepareForDownload

Parameters

buffer	The buffer we're copying from/to. Can be nullptr
texture	The texture we're copying from/to. Can be nullptr

If uploading, the texture will be transitioned to VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL If downloading, the texture will be transitioned to VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL

Parameters

bDownload

True if we plan to do CPU -> GPU transfers False if we plan to do GPU -> CPU transfers

If you want to perform GPU -> GPU transfers, then you need to call:

queue->getCopyEncoder( src, src, true );
queue->getCopyEncoder( dst, dst, false );

Parameters

transitionMode

Only used if texture != nullptr See CopyEncTransitionMode::CopyEncTransitionMode

If this function returns false, waiting on the fence would cause a deadlock since it will never signal.

You must call commitAndNextCommandBuffer before waiting.
