Feasibility of an extension implementation layer for `VK_KHR_dynamic_rendering` ? about vulkan-extensionlayer HOT 5 CLOSED

I'm not even sure if I would take on the work of implementing such a layer (it wouldn't be an easy task) so I'm rather asking out of curiosity, but: Would you be open to taking/reviewing a pull request if someone actually implemented this kind of extension layer ?

Yes, I'd gladly take a pull request if the code works on the platforms we support for the sync2 layer (windows, android, linux) and there are some unit test included.

Sorry for the delay. It seems like it would be feasible to implement but I'm not sure anyone has looked at it in more detail than you have. One thing to keep in mind is that all the renderpass stuff was added to Vulkan to improve performance on mobile tiled rendering GPUs. It might concern some folks if we're encouraging developers towards a non-optimal path.

Thanks.

I really only had use cases in mind where on-chip multipass rendering leveraging multiple-subpass render passes for TB(D)R is not an absolute requirement for performance.

Unlike desktop GPUs that tend to get regular driver updates, many Android devices are stuck on 1.0/1.1 where they won't receive any OTA driver update until the end of time, which is where such an extension layer might come in handy for running future apps written with VK_KHR_dynamic_rendering support in mind.

Regarding dynamic rendering and TB(D)R, an interesting merge request was submitted to mesa which implements VK_KHR_dynamic_rendering for turnip (Vulkan driver for Adreno).
On a related note: many drivers (barring mobile) on mesa seems to be moving towards implementing VK_KHR_dynamic_rendering only, relying on common code path across the driver stack to implement regular render pass on top of it.

Thanks - that clears it up for now !
