Detailed Description

Tracked state for a set of textures, under the discipline the backend records against.

A transition recorded into a command buffer updates the staged view; only a submission that actually reached the queue commits it. An encode that fails partway, or a submit the driver rejects, discards the staging instead - so the table never claims a transition the GPU never ran, which would make every later barrier compute the wrong source scope from a state that does not exist.

forget()

void donner::gpu::vulkan::TextureSyncStateTable::forget

(

uint32_t

textureSlot

)

Forgets a slot entirely, for a texture that no longer exists.

Parameters

textureSlot

Texture slot to drop.

stage()

void donner::gpu::vulkan::TextureSyncStateTable::stage	(	uint32_t	textureSlot,
		const TextureSyncState &	state )

Records that a transition to state was encoded, pending submission.

Parameters

textureSlot	Texture slot the transition applies to.
state	Resulting state.

stateOf()

TextureSyncState donner::gpu::vulkan::TextureSyncStateTable::stateOf ( uint32_t textureSlot ) const

nodiscard

The state textureSlot will be in at this point of an encode: the staged state when one was recorded, otherwise the committed one. A slot never seen reads as untouched.

Parameters

textureSlot

Texture slot to query.
