/* zink_batch_usage concepts:
|
|
* - batch "usage" is an indicator of when and how a BO was accessed
|
|
* - batch "tracking" is the batch state(s) containing an extra ref for a BO
|
|
*
|
|
* - usage prevents a BO from being mapped while it has pending+conflicting access
|
|
* - usage affects pipeline barrier generation for synchronizing reads and writes
|
|
* - usage MUST be removed before context destruction to avoid crashing during BO
|
|
* reclaiming in suballocator
|
|
*
|
|
* - tracking prevents a BO from being destroyed early
|
|
* - tracking enables usage to be pruned
|
|
*
|
|
*
|
|
* tracking is added:
|
|
* - any time a BO is used in a "one-off" operation (e.g., blit, index buffer, indirect buffer)
|
|
* - any time a descriptor is unbound
|
|
* - when a buffer is replaced (IFF: resource is bound as a descriptor or usage previously existed)
|
|
*
|
|
* tracking is removed:
|
|
* - in zink_reset_batch_state()
|
|
*
|
|
* usage is added:
|
|
* - any time a BO is used in a "one-off" operation (e.g., blit, index buffer, indirect buffer)
|
|
* - any time a descriptor is bound
|
|
* - any time a descriptor is unbound (IFF: usage previously existed)
|
|
* - for all bound descriptors on the first draw/dispatch after a flush (zink_update_descriptor_refs)
|
|
*
|
|
* usage is removed:
|
|
* - when tracking is removed (IFF: BO usage == tracking, i.e., this is the last batch that a BO was active on)
